DevOps interview Questions and Answers

April 26, 2019 Interview Questions

Q1) Explain DevOps?

This is a new term perspective in the land, which is not practical focus on software, both cooperation and communication of information technology (IT) professional. It focuses on the provision of software tools promptly and reducing the level of production loss.

Q2) what are the key or Aspects principles behind DevOps?

The basic issues or the principles behind DevOps are

  • Infrastructure such as code
  • Regular humidity
  • Transportation
  • Monitoring
  • Safety

Q3) What is the fundamental Devops used to develop applications and infrastructure?

Devops for basic functions

application development

  • Construction law
  • Legal Insurance
  • The part of the test
  • packages
  • Implementation

and infrastructure

  • Settlement
  • Structure
  • Posting
  • Implementation

Q4) Describe how the “infrastructure framework” is run or implemented by AWS?

AWS,

  • The code will be for JSON infrastructure
  • This JSON item will be held in file formats
  • Templates can be implemented through AWS and then succeeded
  • After CloudFormation service will do, delete, update, etc. working on the cord

Q5) Describe how DevOps is a useful tool for development?

DevOps can help improve the pest and implement new features. It also helps you to clean the links between team members.

Q6) list out some popular tools for devices?Some devices are very popular with DevOps

  • Jenkins
  • Nagios
  • Be aware
  • Elk (Elasticsearch, Logstash, Kibana)
  • Io
  • Jenkins
  • Place a place
  • Accurate
  • Tag
  • collecting / collecting

Q7) For example, how did the SSH be used?

I used SSH to access the remote machine used by the command line. In the same way, we also use systematic methods to facilitate confidential communication between two unrelated groups linked to a secure network.

Q8) Describe how to control the version of the review?

Our system regarding the control of the code control will be published on SourceForge or GitHub so everyone can see it. Also, I do not want to publish the final review checklist to ensure all the problems are solved.

Q9) Describe this type of initiative?

Enter the HTTP requests

  • Success
  • Head
  • placement
  • Printed
  • Users
  • erase
  • Be aware
  • connect
  • choice

Q10) How can you open the terminal very fast for special Ubuntu?

To open a special terminal special Ubuntu you can use the shortcut keyboard.

This, directly in the dance order, adds a new type of genome – Terminal – – Work – directory = / path / to / dir.

Q11) What is the service (continuous integration) CI?

CI service operators must constantly engage in all the changes made and the commitment of the stores made by different developers and to ensure integrated mixing. It is necessary to make the code several times a day, regardless of any death, so that it can detect suicide by breaking breaks.

Ideas: CI and other available tools are Jenkins, TeamCity, circleCI, Hudson, etc. Building

Q12) What is the Continuous Delivery?

Implementing software delivery to test the structure of the IC (continuous integration). It needs to be used as a heavy version of the control system as long as it is always ready for development and testing.

Q13) What is the essence and what is it used to?

Vagabundo is a powerful tool to create or manage a vibrant environment (or container) to test and develop the program. First of all, Vagrant Virtual Box used a technical subject for technical environments, but now it is also compatible with KVM.

Q14) Do you always use the program language?

Most textual, which is simple. In fact, the language itself is not important for understanding the design and development, such as the process, the purpose of the product, or the job program.

Now, many written languages ​​are available so that questions can come up: What is the best language for DevOps? Everything depends on the overall context of the project and its tools, for example, when used Ansible and Python’s knowledge, and if a ruby ​​kid has a baby.

Q15) What are the benefits of DevOps?

To do this, you can use your old experiences and explain how DevOps helps you in your old project. If you do not have these experiences, then you can tell the following benefits.

The benefits of technology:

  • Software transfer
  • Strong and difficult problems to improve
  • Emergency Solution

of benefit:

  • Immediate features of transmit
  • a quiet environment
  • Additional time available to add value (rather than repairs / maintenance)

Q16) What are the key factors that help us achieve?

As a matter of fact, most importantly, Devops helps us to make changes in production as quickly as possible and reduces the risk of quality assurance and follow-up. The main purpose is DevOps. DevOps will learn about this blog.

However, you can add more effects to Devops. For example, clear communication and good working relationship between equipment For example, the two teamwork teams and collaborators who work together to provide quality quality, which results in satisfaction with the consumer.

Q17) Describe the uses of Devops that can be used in real-time industry.

There are many factories in DevOps to write one of these cases, use, you can also refer to the following examples:

Etsy is a central e-commerce network focusing on goods and services, as well as products made from a single plant. Etsy had a problem with the painful site, which often caused a decline. This has affected the sale of millions of people using Etsy who sell goods through the internet and have risen to risk the passengers.

With the help of the new management team management, Etsy changed the cascade, which produced four hours of immigration twice a week, to continue in another way. Currently, the pipelines are full and straightforward, and long-lasting routes that resulted in more than 50 daily operations with little time.

Q18) Describe your understanding and experience both software development and the technical support of the organization he previously worked for.

To respond, share your experience and try to explain how you look forward to the old projects. You can see the following examples:

Engineers DevOps are always used as a 24/7 online business for business. It was made available to the caller’s call to find the exact time, the operating system. We produce the direct approach to supporting the implementation of ongoing programs. I have a great experience and / or public opinion, such as cooker or color, text and appliances such as Python and PHP, and builders.

Q19) What is the DevOps format?

The standard method is the general use followed. When symptoms often accept people who are less than you and your organization will continue to blindly and withstand, you will essentially develop a preventative approach. There are ideas about DevOps. Some include:

  • Devops are a system
  • Connect to the same Devops?
  • Devops Teams should separate
  • DevOps will resolve all of our problems
  • Devops mean productivity management
  • DevOps development is a market for controlling
  1. Devops have not developed the development.
  2. Devops did not do IT operations.
  • We can not Devops – Only for us
  • We can not Devops – We have doubts

Q20) What is the type of control for VCS, and what can I use?

Confirm the copy of the conversation about how the system has been registered for any changes made to one or several files stored in a central location. Mechanisms will help you remember the first part and do the following:

  • Changes in the changes made to take time and then check what works for what we do.
  • send a special or special project to return to the first part.
  • Investigate problems or errors in developmental changes.

Using VCS gives you flexibility to work together to file the file, and any possible changes can be added later.

Q21) Describe how to make Ubuntu machines?

To make a machine machine Ubuntu can be made

Alt + F2 and write “gnome-desktop-item-edit – new creation ~ / desktop” will manage a graphic interface and create machine machine

Q22) Explain what is Memcached?

Memcached is an open source, high performance, reminder system for protection. The main purpose of this document is to improve the response time data that may be recycled or built at another location or data collection. It is used to avoid the need to use SQL data or other similar sources to gain access to the data.

A Memcached can be used

  • Community networks -> Cache Sections
  • Topic Content -> HTML / Web Site Configuration
  • Distribution section -> Cookie / Profile profile
  • Communication -> Cache Cache
  • E-Commerce -> Meeting Codes and HTML
  • Site services -> Weightlifting data
  • sports and recreation -> the next session

Memcache help in

  • Accelerate the application process
  • Decide what is stored and what’s not
  • Reduce the number of applications for recovery data
  • accessing text I / O ((effectiveness)

Drawback of Memcached is

  • It is a permanent database of data
  • No database
  • There is a specific application
  • This can not be cached

Q23) Memcached  some important remembrances.

Memcached contain important features

  • CAS Tokens: CAS A token depends on any item of the item advertisement. You can use the label to save the item.
  • Callbacks: This will facilitate the code
  • getDelayed: Reduce the time you delay your request to return the results of the server
  • Optional method: Binary can be used instead of ASCII and new customers
  • Preventing: In the past, customers are always used to implement the value of complex data, but can be used as a selection line.

Q24) Explain why it is possible to share only one example of Memcache between several projects?

Yes, it is possible to share only one example of Memcache between several projects. Memcache is a shopping center store, and reminders can be done one or more servers. You can also arrange for customers to talk to private agencies. Therefore, you can work in two different ways in the home and not completely free. Except for, if you have data so, it will be necessary to know where to find the data source or postal code.

Q25) You have memory usage, the reminder service fails, and you have the data, which is not always trying to access important server information?

Information on failure of the service does not come up, but there is a requirement for automatic failure, you can count on a few points. Failure can be triggered during any type of string or server failure without errors during regular clients, including key key, and others

Q26) Describe how to stop the secret server reducing?

  • If a sample fails, some small ones, this will put a great deal of data in the data when the information is supposed to be lost and customers request. This is done, if the rule is written to reduce cached stamping and then leave the minimal effect
  • Another way is for example an excuse to appear on the new machine using the IP address of the machine that is not available
  • The law is another option to minimize server closure, because it gives you freedom to change the list of Memcached servers to work at least
  • The site is fully selected for other clients requesting the termination of the Memcached Confidential Service. When reduced, the client will be able to attempt to send an application before crossing the borde

Q27) Describe how you can update when data changes are recorded?

If the information changes, you can renew Memcached

  • Carefully delete the series: Cache Cleanup when you insert or update
  • Recovery of Equipment: This method is the same as the first, but instead delete the key and waiting for the renewal request for the next next data, re-evaluate the value after insertion or renewal.

Q28) Describe its share of Dogpile? How effects can be prevented?

The impact of dogmatic events called stocks, and the site is encrypted by a number of requests from the client. effects it can prevent the use of light traffic. At this time, when the time comes, the process gets the key for the first time and begins to create a new value.

Q29) Describe how you do not use Memcached?

  • Taking normal abusive use is to use the data store, which is different from a facility
  • Never use Collaboration as a source of information you need to manage applications. Data must always be available from other sources, such as
  • The article is the key to savings or can not cover more data or summarize the topic to generate information
  • No MemCached offers any type of security, both laboratory or identity

Q30) If the data collectors do not close the data stored in Memcached are there still?

The information stored on Memcached can not be extended, so if the server is closed or reset and all data stored on Memcached is paid.

Q31) What is the need for DevOps?

In my opinion, this response should begin by explaining the general trend of the market. Instead of launching large feature sets, companies are trying to see if small features can be transported to their customers through a series of launch trains. This has many advantages such as fast response from customers, better software quality, etc. which in turn leads to high customer satisfaction. To achieve this, companies are required to:

  1. Increase the frequency of deployment
  2. Lower failure rate of new releases.
  3. Reduced waiting time between corrections
  4. Fastest average recovery time in the event of a new block.

DevOps meets all these requirements and helps achieve a perfect software delivery. You can give examples of companies like Etsy, Google and Amazon that have adopted DevOps to achieve levels of performance that were unthinkable even five years ago. They are performing dozens, hundreds or even thousands of code implementations per day while offering world-class stability, reliability and security.

If I have to prove your knowledge about DevOps, I should know the difference between Agile and DevOps.

Q32)  How is Agile DevOps / SDLC different?

I advise you to go with the following explanation:

Agile is a set of values ​​and principles on how to produce, that is, to develop software. Example: if you have some ideas and want to turn them into functional software, you can use the agile values ​​and principles as a way to do it. However, that software may only work on a developer’s laptop or in a test environment. You want a fast, easy and repetitive way to move that software to the production infrastructure in a safe and simple way. To do that you need DevOps tools and techniques.

You can summarize by saying that the Agile software development methodology focuses on software development, but DevOps, on the other hand, is responsible for the development and implementation of the software in the safest and most reliable way possible.

Q33) What are the main DevOps tools? In what tools have you worked?

The most popular DevOps tools are mentioned below:

  • Git: version control system tool
  • Jenkins: continuous integration tool
  • Selenium: continuous testing tool
  • Puppet, Chef, Ansible: configuration management and implementation tools
  • Nagios: continuous monitoring tool
  • Docker: containerization tool.

You can also mention any other tool if you wish, but be sure to include the above tools in your response.

The second part of the answer has two possibilities:

  1. If you have experience with all the above tools, you can say that I have worked on all these tools to develop good quality software and deploy these softwares easily, frequently and reliably.
  2. If you have experience with only some of the previous tools, then mention those tools and say that I have specialization in these tools and I have an overview of the rest of the tools.

Q34) How do all these tools work together?

Below is a generic logical flow where everything is automated for a smooth delivery. However, this flow may vary from one organization to another according to the requirement.

  1. The developers develop the code and this source code is managed by tools of the version control system such as Git, etc.
  2. Developers send this code to the Git repository and any changes made to the code are committed to this repository.
  3. Jenkins extracts this code from the repository with the Git plugin and creates it with tools such as Ant or Maven.
  4. Configuration management tools such as Puppet Setup and Puppet Provisioning Environment and then Jenkins release this code in the test environment in which the test is performed using tools such as selenium.
  5. Once the code is tested, Jenkins sends it for implementation on the production server (even the production server is provided and maintained by tools such as Puppet).
  6. After the implementation is continuously monitored by tools such as Nagios.
  7. Docker containers provide a test environment to test the compilation features.

Q35) What are the advantages of DevOps?

For this answer, you can use your past experience and explain how DevOps helped you in your previous work. If you do not have any of these experiences, you can mention the following advantages.

Technical benefits:

  • Continuous software delivery
  • Less complex problems to solve
  • Resolution

Business Benefits:

  • Highest payout feature
  • Active and active areas
  • Additional time available to add value (rather than repairs / maintenance)

Q36) What is the most important thing for DevOps helping us succeed?

In my opinion, the most important thing for Devops to do is to make changes in the production as soon as possible, by reducing the risk of quality assurance and compliance with the software. This is the main purpose of DevOps. Learn more about the DevOps tutorial program.

However, you can add many other effects on DevOps. For example, the correct communication and working relationship between groups, that is, the Ops team and the Dev Team team are working together to provide quality quality software that will satisfy customer satisfaction.

Q37) Explain the uses of Devops that can be used in real life / real life.

There are many factories in DevOps, when you can tell one of them using cases, you can also check the following examples:

Etsy is the e-commerce website that focuses on hardware and products and products, and the specific products made of the plant. Etsy has been chronic in acute and chronic hospitals, which has often led to the crash site. It affects millions of sales for Etsy users who sell products through the internet and are at risk of competing in the competition.

With the help of a new technical management team, Etsy made the cascade model, which produced a full four-hour double-double clock, to continue with other methods. Today, they have a system of full implementation of systematic, regular and resulted in more than 50 activities each day with some mitigation.

Q38) Describe your understanding and experience both in the development of software and in the technical aspects of an organization that you have already done.

In this answer, share your experience and try to explain how you are delicate in the past. You can refer to the following examples:

Devops engineers always work in the online business environment 24/7. I adhere to the guardians’ activities, and they are ready to be in charge of the real time system. We succeeded in automated systems to support the implementation of a permanent software. We have expertise in public / private systems, such as College or Puppet, text and tooling tools such as Python and PHP, and Agile origin.

Q39) What are preventive DevOps?

Usually used is normally followed. If something is ok they do not work for your organization, and you go along without blind, you are based on a preventive approach. There are ideas about DevOps. Some include:

  • Devops are a system
  • Agile equals DevOps
  • We need a special team DevOps
  • Customers will solve all of our problems.
  • DevOps means the product development.
  • Devops is the beginning of developmental development
  1. Devops are not developed for improvement.
  2. Devops do not mean IT activities.
  • We can not Devops – We are special
  • We can not Devops: We have the wrong people

Q40) Why do I need DevOps?

Companies now face the need to quickly implement applications to meet the increasing demand for knowledgeable users to reduce “time market.” Customers often help implement the event quickly.

Q41) Why is essential for the process and the management of the structure?

Discuss the development of software, types and modes, and software types or any test. Explain to the need to maintain and maintain data, retention of data to facilitate a simplified and simplified solution. Do not forget to mention the key CM tool that can be used to achieve this goal. Talk about how to use the puppet, the Ansible, the Chef, and the help of writing software and the configuration of different servers.

Q42) What are the fundamental functions of development and infrastructure?

Devops Primary Functions:

  • Improving the application
  • Improving the rule
  • Legal Insurance
  • The part of the test
  • packages
  • Settlement and infrastructure
  • Settlement
  • Structure
  • Posting
  • Implementation

Q43) The concept of “Infrastructure” as the code (IAC) is a little too small?

It is a good idea to talk about the CAI as a concept, sometimes referred to as the infrastructure of the program, where the infrastructure is compared to the other. Defines the traditional management structure required to take the seat as the restructuring, loss of equipment, and special writings that may be unreliable. In addition, to strengthen the IAC benefits and how IT infrastructure changes can be implemented quickly, safely and easily used by IAC. Other advantages include IAC such as application codes used for the test and interoperability, and maintenance of infrastructure updates.

Q44) What is SSH size?

SSH Secure Shell provides users, a secure system to access system files and transfers.

  • To access the remote machine and use the command line.
  • To check the applicant’s relationship between two groups in a secure network.

Q45) What is the difference between the Linux and Unix Ubuntu system?

Unix:

  • It is part of a complex, multi-family system.
  • Usually used for servers and workplaces.
  • Originally from AT & T Unix, since the Bell Labs Research Center of Ken Thompson, Dennis Ritchie and others.
  • Two surgical systems are open source, but UNIX is similar to Linux.

Ubuntu Linux:

  • Ubuntu Linux may have been a part of the human language programming language.
  • Used for personal computers.
  • Linux computers are based on the UNIX operating system.

Q46) HTTP’s type of application?

Enter the HTTP requests

  • Success
  • Head
  • placement
  • Printed
  • Users
  • erase
  • Be aware
  • connect
  • choice

Q47) What affects the impact of floods and how can be prevented?

The impact of dogmatic events called stocks, and the site is encrypted by a number of requests from the client. Looga effects it can prevent the use of light traffic. At this time, when the time comes, the process gets the key for the first time and begins to create a new value.

Q48) VCS What do you mean by comfort?

You can only call only VCS has worked this way: “I worked on any of the most important advantages of many tools as SVN other VCS is the distribution system version distribution system”

Distribution of the distribution version is not connected to the central server to store all the parts of the project we are in. In contrast, each clone developer and a copy of the store have a full history of jobs on the stronger core.

Q49) Different situations between Memcache and Memcached.

Appeal: This will allow you to work through the Consumer Objectives (OOP) people and the process of performance. It is designed to reduce the size of data in the active web applications

Note: This is an extension that uses the libmemcached library to provide the APIs for communication with the stolen server. It is used to improve online web applications by minimizing data retention. It is the latest API.

Q50) Describe how you can update when the data changes are recorded?

If the information changes, you can renew Memcached

  • Carefully delete the series: Cache Cleanup when you insert or update
  • Restore Device: This method is the same as the first, but instead delete the key and wait for the next renewal request.

Q51) What is the automated test, some of the benefits?

Automation testing or Test Automation is a way to check the manual process to test the application / test system. The automated test involves the use of different experimental tools that allow you to make test scanners that can be maintained regularly without need for interference. Some of the benefits are listed:

  • Supports the frequency of examinations
  • Assistance to test the test of the test
  • Allows the implementation of comparisons.
  • Encourages the implementation of an uncontrolled killings
  • Improves the fact that reduces the mistakes made by the man
  • Provides time and money.

Q52) What are the benefits of using Version Control?

We will suggest you add the following benefits for version control:

  1. Through the Version Control System (VCS), all members of the group can freely operate the file every time. VCS will then allow you to add all the changes in a normal copy.
  2. All previous types and types can be carefully inspected in VCS. When you need it, you can request a week at any time, and you will have a complete picture of your fingerprints.
  3. Each time you store a new part of your project, your VCS wants you to provide a brief description of what has been changed. In addition, you can see the correct way to convert the contents of the file. This will allow you to know who made the project changes.
  4. VCS distributed as Git allows all members of the group to have a complete history of a project, so if there is a moderator in the middle, you can use one of the traditional budgets of your friends.

Q53) How is the difference between Agile DevOps / SDLC?

I advise you to follow the following explanation:

Agile is the foundation of principles and principles of production, that is, software development. For example: if you have ideas you want to return to software behavior, you can use the values ​​and principles in the area to do. However, this program can only work on your laptop or computer. You want a simple, easy and repetitive way to speed up the software for infrastructure development in a safe and simple way. To do this, you need Devops and techniques.

You can briefly say that the software development environment is focused on software development, but DevOps, on the other hand, is responsible for the development and implementation of the most reliable software. Here is a blog that will provide you with more information about DevOps development.

Q54) How to share all of this equipment?

Below is a logical sequence of everything that is used directly. However, the flow may vary from one organization to another according to the requirements.

  1. Development of code development and the code set are governed by the version control systems such as Git, etc.
  2. The shipping agents refer to Git Gitar Code and any changes made to the code are determined by this item.
  3. Jenkins makes this key number of Git’s plug and creates tools such as Ant or Maven.
  4. Construction management tools such as Puppet Setup and Puppet Provisioning Environment, and Jenkins releases this test code for testing a device like selenium.
  5. When the code is tested, Jenkins sends the execution of the production server (even the manufacturer’s product is provided on the Puppet).
  6. After the implementation is monitored regularly with the equipment such as Nagios.
  7. Clay containers provide an environmentally-friendly environment to test the complexities.

Q55) What are the benefits of DevOps?

In this answer, you can use previous experiences to explain how DevOps has helped you in your past work. If you do not have one of these experiences, you can tell the following benefits.

The technical benefits:

  • Paying for a regular program
  • Less than the harder problem solving
  • Solving the problem of growth.

Business Benefits:

  • Highest payout feature
  • Active and active areas
  • Additional time available to add value (rather than repairs / maintenance)

Q56) What is the most important thing to help DevOps?

In my opinion, the most important thing for Devops to do is to make changes in the production as soon as possible, by reducing the risk of quality assurance and compliance with the software. This is the main purpose of DevOps. Learn more about the DevOps tutorial program.

However, you can add many other effects on DevOps. For example, the correct communication and working relationship between groups, that is, the Ops team and the Dev Team team are working together to provide quality quality software that will satisfy customer satisfaction.

Q57) What are the methods of preventing Devops?

Usually used is normally followed. If something is ok they will not work for your organization, and you continue to blindly, that, in essence, taking a preventive system. There are ideas about DevOps. Some include:

  • Devops are a system
  • Connect to the same Devops?
  • Devops Teams should separate
  • DevOps will resolve all of our problems
  • Devops mean productivity management
  • DevOps development is a market for controlling
  1. Devops have not developed the development.
  2. Devops did not do IT operations.
  • We can not Devops – Only for us
  • We can not Devops – We have doubts

Q58) What is the version control?

This question seems easy and will meet with the interview. The first suggestion gives you the definition of version control. This system will record the file changes or the amount of files after the time to remember the next specific components. The computer control system is composed of a shared central center where friends can verify file changes or files. Next, version control operation can be specified.

Control of the virus allows you to:

  • Go back to the state again.
  • Returning to the entire project back to a former government.
  • Time conversion comparisons.
  • Look at something that has been altered and stopped and can cause the problem.
  • Who exhibits a problem when.

Q59) What is the most common type of control?

We will propose the following benefits, including checkers:

  1. Through the version of the VCS, all members of the group are allowed to work freely in any file at any time. VCS will then allow you to add all the changes in a normal copy.
  2. All types and variations that were carefully documented in the VCS. If necessary, you can apply any version at any time and they will have a thorough understanding of the work in the right hand.
  3. Whenever a new version of the project is saved, you need VCS to provide an explanation of what hostel has been changed. In addition, you can see what’s right in the file section. This will allow you to find out who has changed the project.
  4. A distributed VCS such as Git allows all members of the group to have additional work history so that if there is a moderate server damage you can use one of his friends’ stores.

Q60) What is Git?

I would recommend you to try this question by explaining the structure of each one as shown in the following chart. You can refer to the following information:

The distribution module distributed is distributed (DVCS). You can search for a file change that allows you to return to the course.

  • Distributed designs provide many benefits for other versions of the VCS (SVC) as SVN is a great benefit not based on the central server to store all versions of our project. Instead, make each of the “clones” of’ve copy a collection of the following image with a “local store” and the date is full of hard disk hard work and so on if there is a server power, all you need to do is back up Your recovery is one of the repairs in each of your neighborhoods.
  • It is also a storage tank in the center where the development can make changes and other shared companions as you can see in the diagram that all employees are made to make a “Deep Store” change.

Q61) What are the use of version control?

  • Return to state files.
  • Return to the entire project in the region.
  • Compare changes after a period of time
  • See the last thing that has changed something that might cause problems.
  • Who introduced problems and when?

Q62) What are the main functions of DevOps in terms of development and infrastructure?

DevOps Response The most important tasks are: application development, code development, code insurance, unit test, packages, infrastructure, provisioning, design, orchestration and implementation.

Q63) What is a Continuous testing?

Continuous response testing is the implementation of the interconnected part of the software delivery line to get an immediate response to the business threats associated with the latest construction.

Q64) What is automation testing?

Automation Testing or Automation Assessment is a system of testing tools to test the application / testing system.

Q65) What are the main features of the Continuous testing?

Responding to risk assessment, political analysis, looking at terms, advanced analysis, designing experimental and service design

Q66) What types of tests are supported by Selenium?

Respond to regression tests and test scores.

Q67) Separation of property management and configuration management.

Evaluation of property management, generally refers to any monitoring system that maintains the value of an organization or group.

Structuring management is the planning process, identification, hand and confirmation of configuration (CIS) within your service, state register and support management change, evaluates the impact of IT on these substances.

Q68) What is the Puppet?

A structuring management tool used to eliminate administrative tasks.

Q69) How do I work for HTTP?

The HTTP Act operates as a customer and service model like most other types. A browser browser to start the application is called the client and the web server software to respond to an application called a server. The Consortium Web Wide World and the Internet Engineering Task Force are two major channels for HTTP protocols.

Q70) Describe Two Factor authentication?

Two factor factors are a security system that the user provides two ways to identify specific certificates; This is usually a physical record, such as a card, and a reminder, as a security code.

Q71) What are the benefits of using DevOps?

In DevOps, the development of a small development development based primarily on the size of the country is likely to end in two to four weeks; so that any change in business needs can easily be mapped to the next competition.

Devops, many of the solutions that can be used with the help of the API can be reused, third-party services, etc. This helps to reduce the development time, so most of the new number it only needs looga connectivity and configuration.

Q72) What is the XP program?

The radicalization program is generally regarded as XP as one of the most popular ways of using an advanced program. The XP Act is intended to focus on customer satisfaction. This allows for the development, with some conflicts, to confidently respond to a change of circumstances. XP enhances collaboration between customers, customers and developers as partners in team work. Most companies use XP on their trip to DevOps.

Q73) What is Pair program?

Shared program is one of the most demanding engineering requirements. In this sense, both programs work on the computer, the same / algorithms / code / test.

Programs that act as a “driver” and others act as an “observation” monitor / monitor to identify the problem. Both can be changed at any time without downloading.

Q74) What are the benefits of a pair program?

Men’s programs help focus on two different perspectives, which will also help to better understand the code / algorithms / design / testing.

Q75) What is the TDD test?

Driven Development is one of the DevOps software programs in real time and quickly contributes to the constant recovery of integration. This method, a case study, is crucial for the development process. This method ensures rapid identification of problems that pose a significant risk of risk management.

TDD is a tool in which the code is written to deal with an unsuccessful trial case. Not only was the screening method considered, but also the concept of design and development.

TDD began to meet customer requirements, test results, and test results. Experimental case failed because there is no screening test; Next, write a simple code to complete the experiment.

Q76) What are the advantages of developing a test drive?

TDD starts as the previous case, the quality of the code will increase so that one or more test scenarios exist for all activities.

  • The Repatriation Act can be done with confidence.
  • after a while, application codes; Since then, he has included all the test instructions.
  • The law stated that due to the small partial configuration it is more fragmented and flexible than the test title.

Q77) What are the benefits of continuous integration?

The program can be run at any time. It has mechanical feedback and emergency response techniques and reacts quickly when no substance is available.

Quality equipment quality improves to prevent conflicts.

On the basis of automated testing and diagnosis, the healthcare program is easy to access.

Results of the printed form, the most common unsuccessful cases.

The account code is always recorded.

Q78) What is Continuous Deployment?

hand instrumentation, to follow unnecessary steps in the life cycle of the project in urinating the production quality code production quality levels. Regular delivery is permitted for regular delivery of pipes. There are several ways to enable uninterrupted DevOps.

Q79) What is the importance of Continuous Testing?

The regular test is meant to do all exams throughout the software development program that allows regular testing and verification of the number; to make sure that the code really works and works as intended.

One needs to look at regular checkpoints through Lens DevOps; creating a secure network for groups to develop, experiment and release new jobs without increasing the quality

This can be achieved through the use of automated testing, test data management, CI and much more.

Q80) What is Functional Testing and Non-functional Testing?

The performance tests often focus on business goals to ensure that, the structure and the rules of the code, the product meets customer requirements.

On the other hand, non-working exams focus on performance, security, harmony, use, experience, use of resources, etc.

Q81) DevOps! How do you define your words?

The active daily collaboration between software development and IT / IT activities to produce a technical system or program.

DevOps implementation is generally integrated in agile, where implementation of the program of employment is generally the first priority. Implementation of the effort, and focus people on the system, the DevOps engineer must be ready to closely by the development of effective work to ensure that the need to support local features such as test integration, permanent integration and regular payment. In the traditional implementation of DevOps, the business team is primarily responsible for the development, most of which works under a table model helps low-level contracts with the public service, where operations team procedures treat customer development. This is a proven model that obviously works very well, but in a DevOps environment, improvements and operations have facilitated and the barriers between the two groups should not exist.

Q82) Why do I need DevOps?

Companies now face the need to quickly implement applications to meet the increasingly demanding pressure of conscious users to reduce Time to Market. Customers often help implement the event quickly.

Q83) What is the development of blueprints and biases?

Environmental development is used to change water culture practices. In contrast, the development process is a continuum and increase test, over and beyond any developmental milestone, apart from the last phase of a flood.

Cotton is used to manage the computer programming and product development, using traditional methods and performance improvements. The size has three roles: the owner of the product, the residency teacher and the team.

Q84) Can we consider Devops as the most appropriate way?

Of course! Devops is the movement of reconciliation and integration into development and production through better ways. The appearance of the image includes a huge change in the company’s requirements, which want to change the trend so that it meets the requirements of the companies and customers.

Q85) What is the role of mobile phone management tools?

Cars play a key role in the management of the server. We use CM tools, store information on versions and build software software and test and provide inter-software and software software.

Q86) What is the purpose of CM equipment and what is used?

The purpose of the framework management tool is to eliminate and configure a large number of servers. Most CM equipment often use the structure of the agent, which means that the machine is being operated must have the installed installation. My favorite feature is one of the uses of the construction without the agents – Ansible. It only needs SSH and Python. And if the module is not used without it, Python does not even need it because it can handle fraudulent orders. Other popular equipment and CM are Puppet, SaltStack.

Q87) What is OpenStack?

OpenStack is often referred to as OS on the path, which is not far from the truth. It is the full functionality of the IAAS implementation that gives you the possibility to create a compact, like AWS. It is very high and consists of more subdivisions so you can choose and choose which jobs you need. OpenStack can be found in Red Hat, Mirantis, HPE, Oracle, Canonical and many more. It is openly open, but some providers make customer distribution.

Q88) Have a ‘cloud’ and ‘category’?

software cloud computing software such as Software such as Service or SaaS, Infrastructure Services or IaaS and Platform such as Service or PaaS.

SaaS is an encrypted program that works on a network that uses only one mediator for users, most of the web sites. For example, salesforce.com.

Infrastructure services are an environment that demonstrates the use of a technical machine user to use a functional system or a complete package to install everything that is installed in the server. For example this can be OpenStack, AWS, Eucalyptus.

PaaS allows users to implement their applications in the pre-built program, generally in the form of the app submissions.

Q89) What is the easiest way to build a small cloud?

VMfest is one of the possibilities for creating IaaS cloud computing from VirtualBox machine tools. If you want a PaaS light, there is a Dokku, which is basically a printed project that makes PaaS to leave the Dokku container.

90) What are the responsibilities of the engineer DevOps?

Engineer Devops works closely with local development groups to ensure that they have an environment that is essential to support jobs such as automated testing, regular interaction and regular delivery. Engineer Devops should constantly communicate with producers all the key parts of the environment that work well.

Q91) Are you more than a Dev or Ops?

VMI: What I want to say Do you do extra work like a manager’s manager or do you spend a lot of time working with voters?

This depends on a lot about work, the company you are working on and the people involved. You should actually be able to switch to both sides of the fence at any time.

In the past, I have done a lot. But now my work focuses on design and coordination.

Q92) What is a DevOps device that you like to use?

I will use Ansible, and we use Ethics.

Jenkins is another device that works easily and does what he thinks he is doing.

Go, Maven and Python are also well-established.

I also found that my Perl program experience allowed me to study and codify the languages ​​of other programs very quickly.

And finally, but at least, earlier I enjoyed using Ruby with small tests for automation and testing. I also used other expensive equipment, but open openings are always working for me.

Q93) What texting languages ​​do you think is the most important for a DevOps Engineer?

Like textual languages, make it easier and better.

Python seems to be very popular, but personally I like Ruby and Perl (which was the flavor).

Language itself is not important in strategic and academic development.

As a scheme, the program’s purpose or program of work.

Q94) Which book do you recommend someone who wants to start learning DevOps?

It relates to the history and experience of the people, but not even for some experience

Improvement of infrastructure and infrastructure management, can recommend the following:

  • Pragmatic program: from Journeyman to Master by Andrew Hunt and David Thomas
  • Time management manager Thomas Limoncelli
  • Continuous Integration: Improving software quality and risk reduction Paul Duvall
  • In addition, we would also recommend the following:
  • Phoenix project: drama about IT, DevOps and how to help your successful corporation Gene Kim
  • (Well known looga at DevOps), Kevin Behr and George Spafford
  • The work of Jason Fried

Q95) What is the most important thing for DevOps to help?

Personally I think the most important thing DevOps helps to make is changes (dry bags and new ones

Operations) as soon as possible and reducing the risk of ensuring quality of service

and compliance. That’s the main goal / goal of DevOps.

However, there are many other things that are harmful to DevOps.

Q96) Explain the concept of “building” like the code (IaC)?

It is a good idea to talk about the idea of ​​the IaC, sometimes called a comparable computer, where the infrastructure is recognized as the other one. Describe how the traditional management process of managing management relies on and how to use enhancement tools, early tools and unique textures can be unreliable. Next, focus on the benefits of IaC and how IT infrastructure changes can be implemented as fast, safe and simpler as IaC. Include other IaC benefits, such as celluloid testing applications and integration experiments for interchanges and repair of renewable infrastructure.

Q97) What is SSH size?

SSH is a secure environment that provides users with a safe and enriched system to access systems and transfer files.

  • To leave the remote machine and operate the Command Line.
  • Protect communication between two groups through a secure network.

Q98) What are the differences between Linux and Unix operating systems?

Unix:

  • It belongs to families with complex systems, many working systems.
  • These are usually used for Internet servers and workplaces.
  • Originally from AT & T Unix, made from 70 of the Bell Labs research center Ken Thompson, Dennis Ritchie and others.
  • Two systems are open source, but UNIX is different from LINUX.

Linux:

  • Linux is likely to be the home of all human language programs.
  • These are used for personal computers.
  • LINUX is based on the UNIX operating system foundation.

Q98) HTTP application types?

Types of HTTD applications are

  • Git
  • HEAD
  • PUT
  • POST
  • PATCH
  • DELETE
  • TRACE
  • CONNECT
  • OPTION

Q99) What is the nature of Dogpile?

The impact of Dogpile refers to the event that the adolescents are exposed and the websites are affected by multiple requests made by the same customer. Effects can be avoided by the use of lights cars. In this scheme, when the price goes down, the first way gets the blockage and begins to create a new value.

Q100) What is a VCS device that you feel comfortable?

You can only tell the VCS equipment you have worked on: “I worked in Git and one of the biggest advantages over other VCS devices such as SVN is to implement a system for controlling the system” .

The distributed VCS device is not connected to the central server to store all file files. On the contrary, each one of the clones develops a copy of the stack and has a complete project history on a complex path.
