How does HTTP work? How does a web page appear in a browser?
Basically, to prove that you understand (at a high-level) the infrastructure you&rsquo;ll be working with, as well as the ability to explain concepts to others. <a href="https://devops.com/" target="_blank" rel="noopener">DevOps</a> is about communication too, remember?
Tell me about the worst-run/best-run outage you&rsquo;ve been a part of. What made it bad/well-run?
Take lessons from both failures and successes in dealing with outages. Remember, there's no shame in talking about the mistakes you've learned from.
How would you prepare for a migration from one platform to another?
Fairly self-explanatory, how do you handle transitions? How do you document the current state of your environment before moving, and how do you validate everything is as it should be after the fact?
How do you handle interruptions?
While it&rsquo;s going to be your job to&nbsp;stop&nbsp;interruptions, how you deal with them now is important for getting an idea of if you know how to fix them quickly and if you know how to make devs and ops work together.
How would you deploy software to 5000 systems?
Do you know how you would go about large-scale deployments?
What different types of testing need to be carried out on a software system, and what tools would you use to achieve this testing?
For starters, you probably would want to test that your configurations are correct before and after making changes, and know how to validate that your environments are all consistent.
Discuss your experience building bridges between IT Ops, QA and development?
DevOps is all about effective communication and collaboration. I&rsquo;ve been able to deal with production issues from the development and operations sides, effectively straddling the two worlds. I&rsquo;m less interested in finding blame or playing the hero than I am with ensuring that all of the moving parts come together.
What types of testing are needed?
Software teams will often look for the &ldquo;fair weather&rdquo; path to system completion; that is, they start from an assumption that software will usually work and only occasionally fail. I believe to practice defensive programming in a pragmatic way, which often means assuming that the code will fail and planning for those failures. I try to incorporate unit test strategy, use of test harnesses, early load testing; network simulation, A/B and multi-variate testing &nbsp;etc.
Which scripting languages do you think are most important for a DevOps engineer?
As far as scripting languages go, the simpler the better. In fact, the language itself isn&rsquo;t as important as understanding design patterns and development paradigms such as procedural, object-oriented, or functional programming.
How do you expect you would be required to multitask as a DevOps professional?
Focus attention on bridging communication gaps between Development and Operations teams.
Understand system design from an architect&rsquo;s perspective, software development from a developer&rsquo;s perspective,operations and infrastructure from the perspective of a seasoned Systems Administrator.
Execute-&nbsp;to be able to actually do what needs to be done.
What testing is necessary to ensure that a new service is ready for production?
DevOps is all about continuous testing throughout the process, starting with development through to production. Everyone shares the testing responsibility. This ensures that developers are delivering code that doesn&rsquo;t have any errors and is of high quality, and it also helps everyone leverage their time most effectively.
What&rsquo;s a PTR in DNS?
Pointer records are used to map a network interface (IP) to a host name. These are primarily used for reverse DNS. Reverse DNS is setup very similar to how normal (forward) DNS is setup.&nbsp; When you delegate the DNS forward, the owner of the domain tells the registrar to let your domain use specific name servers.
Describe two-factor authentication?
Two-factor authentication is a security process in which the user provides two means of identification from separate categories of credentials; one is typically a physical token, such as a card, and the other is typically something memorized, such as a security code.
What other tools might help you in this role?
DevOps is so diverse and inclusive that it rarely ends with coding, testing and systems. A DevOps project might rely on database platforms like SQL or NoSQL, data structure servers like Redis, or configuration and management issue tracking systems like Redmine. Web applications are popular for modern enterprises, making a background with Web servers, like Microsoft Internet Information Services, Apache Tomcat or other Web servers, beneficial. Make sure to bring across that you are familiar with Agile application lifecycle management techniques and tools.
Tell us about the CI tools that you are familiar with?
The premise of CI is to get feedback as early as possible because the earlier you get feedback, the less things cost to fix. Popular open source tools include Hudson, Jenkins, CruiseControl and CruiseControl.NET. Commercial tools include ThoughtWorks&rsquo; Go, Urbancode&rsquo;s Anthill Pro, Jetbrains&rsquo; Team City and Microsoft&rsquo;s Team Foundation Server.

Make sure to bring across that you are familiar with Agile application lifecycle management techniques and tools.
<h3>Q12. Which are the top DevOps tools? Which tools have you worked on? </h3>
Ans: The most popular DevOps tools are mentioned below:
<ul>
<li>Git: Version Control System tool</li>
<li>Jenkins: Continuous Integration tool</li>
<li>Selenium: Continuous Testing tool</li>
<li>Puppet, Chef, Ansible: Configuration Management and Deployment tools</li>
<li>Nagios: Continuous Monitoring tool</li>
<li>Docker: Containerization tool You can also mention any other tool if you want, but make sure you include the above tools in your answer. The second part of the answer has two possibilities:</li>
</ul>
<h3>Q13. How do DevOps tools work in collaboration?&nbsp; &nbsp; &nbsp;&nbsp;</h3>
Ans:&nbsp;The following workflow tells how the DevOps tools work cordially, and this workflow varies from organization to organization.
<ul>
<li>The source code developed by the developers is handled by VCS tools like Git, Subversion etc..</li>
<li>In Git tool,&nbsp; git archive or repository handles the code and modifications made in the code is saved to it.</li>
<li>Jenkins picks the code from the archive with the help of a git plugin and builds it with the help of tools like Ant or Maven.</li>
<li>Jenkins test the code in the testing environment which is configured by the puppet, and then it dispatches the code for installation on the production server.</li>
<li>Tools like Nagios, Docker container do continuous monitoring and testing on the build.&nbsp;&nbsp;</li>
</ul>
<h3>Q14. What is the primary objective of DevOps?</h3>
Ans:&nbsp;The primary objective of DevOps is making changes to the final product instantly and achieving the required quality in the end product. DevOps also makes the operations team and development team collaborate to deliver a good quality product.
<h3>Q15.&nbsp; Explain Git Architecture?&nbsp;</h3>
Ans:
<ul>
<li>&nbsp;Git is a distributed version control system,&nbsp; it enables us to record the modifications of a file and facilitates us to revert to any specific change.&nbsp; &nbsp; &nbsp; &nbsp;</li>
<li>&nbsp;Due to its distributed architecture, git has many advantages. one primary advantage is that developers can store the duplicate copy of project history on their hard disks instead of depending on the central server.</li>
<li>when any changes are made to the existing files or created any new file, then we can share these changes with the teammates by sending these changes to their local repository through a remote repository. For this purpose, we can use &ldquo;git pull&rdquo; command.</li>
<li>&nbsp;when we face server outrage, these local repositories are useful for sharing the information among the teammates.&nbsp;</li>
</ul>
<h3>Q16. Explain the implementation of continuous integration in DevOps?</h3>
Ans: Following the below four phases present in the continuous integration implementation:
<ul>
<li>Commit: In this phase, new features or new modifications are integrated with the base code and with the help of Jenkins tool unit and sanity testing is performed on the new code.</li>
<li>Build: After the code is integrated and tested, the second phase is to build the code with the help of Dockers tool.&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;</li>
<li>Test: In this phase, alpha and beta deployments take place to check the performance of the new builds and to perform manual testing on the application.&nbsp;</li>
<li>Production Deployment: This is the phase, where application or product goes live, after testing the build successfully.</li>
</ul>

A person who has skills in coding or scripting and brilliance to become deployment or system admin can perform this role.</li>
</ul>
<h3>Q18. What are the measures that successful DevOps involves?</h3>
Ans:
<ul>
<li>&nbsp;The first measure for DevOps success is reducing the delivery time which means the duration for the project item to enter into a production environment.</li>
<li>&nbsp;with the help of agile methodology, we have to decrease the production-level defects.</li>
<li>&nbsp;we may face a situation in which deployments may get failed, to avoid this we should have a mechanism to go back to our previous version.</li>
<li>&nbsp;DevOps should minimise Mean Time To Recover(MTTR) as it measures the average time required for the product to recover from the failure in the production environment.&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;</li>
<li>&nbsp;Performance of the application and number of bugs are the key measures for DevOps success. These two are depended on the quality of the application.&nbsp; &nbsp; &nbsp;&nbsp;</li>

DevOps Interview Questions

<h2 style="text-align: justify;">How to solve the dilemma of choosing between DevOps Engineering And Full-Stack Development?</h2>
With the advent of Ops, the developers are being forced to choose either full-stack or Ops as their key skill. Full-stack means the developer is well versed in developing front-end as well as back-end applications by using the latest languages and tools being used. Ops mean that the developer is a subject matter expert in any one area of implementation &ndash; be it server-side programming, database management, or application programming &ndash; and that too by possessing knowledge of any one (or max two) of the languages and tools used for development in that area.
Full-stack developers are lagging in the expertise of late, and most of the software development India companies prefer hiring Ops developers for their development needs. This is because the technology-specific delivery demands have made the process to complex to be handled by full-stack developers.
Ops processes make it essential to build a team of developers who are experienced in various areas of development and collaborate to deliver a solution that is the collective effort of this expert team. This approach to application development has changed how developers think and the technologies that they use because rather than having skill in every possible area, the developers are required to priorities agility, modularity, and scalability in their own area of expertise. This makes specialization and deep expertise more valuable than full-stack knowledge (in an Ops environment).

</blockquote>
<h2 style="text-align: justify;">DevOps Engineering And Full Stack Development</h2>
However, it is necessary to evaluate the exact needs of the enterprise before leaning towards a full stack or Ops hiring approach. Following are the key questions that need to be addressed to arrive at a conclusion:
<h3>1. Is your software stack complex?</h3>
Software stacks are much more diverse and variable these days. For example, Java has two runtime environments now. MySQL is not the only preferred DB solution, there is NoSQL too. In this scenario, if your application stack is too complex, it is futile to expect expertise in so many technologies from a full stack developer. It makes sense to opt for Ops and hire technology-specific experts for each stack element.
<h3>2. Do you really need agile implementation?</h3>
Agile implementation is for applications that are trying to keep up with highly volatile consumer markets, where there is intense competition between similar companies to come up with latest features that tilt the balance of customers on either side depending upon the utility provided by those features. If the enterprise is an industry facing entity, which has legacy solutions that do not require frequent changes other than white labelling for the customer companies, going for Ops does not make sense. The enterprise would do better with full-stack developers who can handle minor version changes and maintenance needs of the application.
&nbsp;
<a style="background-color: #e94350; color: #ffffff; padding: 10px 20px;" href="devops-interview-questions" target="_blank" rel="noopener">DevOps Interview Questions</a>
&nbsp;
<h3>3. What team size do you require, and what is your budget?</h3>
The team size per project depends less on the application needs and more on the enterprise&rsquo;s ability to spend funds on hiring the team these days. This is a faulty approach. The team size should be decided based on the complexity of the application, and the areas of expertise required to build the application.
If it is a complex application that requires modularity and uses diverse stacks, it requires Ops resources. If the application scope is limited, with no complexity, and few update requirements, full-stack developers can suffice.
In case of complex applications though, the budget plays a big role in hiring as Ops developers charge outrageous amounts of money in lieu of their deep expertise in the field. If the budget is limited, the enterprise should opt for full-stack developers instead.
<h3>4. What are your growth plans?</h3>
Startups are mostly required to roll out frequent app releases. Enterprises try to mimic their operation style and end up spending time and money without significant returns. Startups opt for Ops because they cannot survive without it. Enterprises should take the call based on their future growth plans &ndash; is their application suite adequate or expected to grow? Are their applications subject to frequent changes or legacy applications that evolve over a larger time frame?
To conclude, there is no right or wrong in choosing full-stack or Ops for <a href="https://www.nexsoftsys.com/services/offshore-development-center.html" target="_blank" rel="noopener">Software Development</a>&nbsp;India. It depends on the specific needs of the company hiring the resources.

<h2 style="text-align: justify;">What is DevOps?</h2>
DevOps is a set of practices which automates the processes between IT and Software development teams to develop, test and release software much faster and more reliably. <a href="devops-tutorials" target="_blank" rel="noopener">DevOps</a> is founding on building a collaborative culture between teams that functioned in relative silos. 
It is the combination of cultural philosophies, tools and practices that increase an organization&rsquo;s ability to deliver services and applications at high velocity: evolving and improving products at a rapid pace than others using conventional software development and infrastructure management processes.
The primary benefits include faster software releases, increased trust and ability to solve critical issues quickly and to manage unplanned work in a better way. For having a clear understanding, DevOps means a combination of distinct people with different things covering a lot of ground.
<h2 style="text-align: justify;">What are the DevOps tools?</h2>
DevOps is a culture in software engineering. The aim or objective of DevOps is to unify software development and software operations (Dev+Ops). It is a broad area involving distinct tools at different phases/stages. There are separate tools available to implement DevOps. 
Any tool you select entirely depends on Model and infrastructure in which you want to develop particular software. There is no concept of one DevOps tools is higher than the other. It is just because of the choice of the user or the business infrastructure that requiring that tools.

<h3 style="text-align: justify;">Some of the most common DevOps tools used frequently:</h3>
<a href="jenkins-training" target="_blank" rel="noopener">Jenkins</a>: Written in Java and is a continuous integration server used to test and tell about changes in real-time. It also helps developers to solve bugs in code and to automate the testing.
Docker: Platform for distributed applications helps engineers to build and run an application. It helps in assembling apps from components.
Git: Being a version control system helps and allows engineers to track file changes. Git&rsquo;s features include adding/moving files, ignoring specific data, branches, and finding versions introducing a bug using binary search.
Selenium: To develop tests, automated tests and provides the easy interface. <a href="selenium-training/" target="_blank" rel="noopener">Selenium</a> offers a portable software testing framework for web applications.
Ant: A Java library and a command-line tool, helps to drive processes as targets and extension points based upon each other. It provides numerous built-in tasks and can plot any method that is described regarding goals and functions.
Ansible: An open-source tool that automates IT infrastructure and apps including network configuration, cloud deployments, and development environment creation.
<h2 style="text-align: justify;">What is the Importance of DevOps?</h2>
DevOps describes a set of processes and culture that combines development and operations teams to complete developing software. It allows companies to create and improve products at a quick pace when compared with conventional software development methods. 
<h3 style="text-align: justify;">Here are the top reasons why Industry is quickly adopting DevOps principles:</h3>
<ul style="text-align: justify;">

<li style="font-weight: 400;">Soft skills are a must-have</li>
</ul>
There is an intense need of experts having an ideal arrangement of DevOps abilities in the DevOps area. Today DevOps has transformed into a requesting space with groundbreaking associations sending code up to multiple times more than contenders. The achievement rate of organizations is over 50.
The primary tasks of DevOps engineers include:
<ul style="text-align: justify;">
<li style="font-weight: 400;">Expertise in programming code testing and arrangement </li>
<li style="font-weight: 400;">A firm establishing in the agile procedure of undertaking the management </li>
<li style="font-weight: 400;">Deploying the different automation devices of DevOps to perfection </li>
<li style="font-weight: 400;">Working with an assortment of open-source tools and advancements </li>
<li style="font-weight: 400;">Having exhaustive learning of the IT activities and sysadmin roles </li>
<li style="font-weight: 400;">Ability to associate the technical &nbsp;and business objectives with an energetic willingness </li>
<li style="font-weight: 400;">Excellent aptitudes in correspondence and working with groups.</li>
</ul>
The DevOps engineer should ensure that the code has changed that is incremental and frequent. Thus a DevOps engineer should know distinct coding elements along with software development kit and libraries to integrate discrete SQL components of data manager or software release messaging tools on the production infrastructure or the operating system.
Therefore, the role of a DevOps engineer is not just one position but has to struggle between multiple tasks to do justice to the task assigned to him. He should have the skill sets like coding, testing and integrating. The functions of a DevOps engineer is about solving organization problems and improving the business process.
<h2 style="text-align: justify;">DevOps Vs Agile: What&rsquo;s the Difference?</h2>
To distinguish between DevOps and Agile in a better way, let&rsquo;s take a look back at the pre-agile era. While both of these are common terminologies used in software development, they are neither same nor foes.
Definition of Agile and DevOps: DevOps is the offspring of the model of Agile that works beyond the software team. Both of these procedures each other complements for faster production and quick delivery, but both of them perform it differently. Coming to Agile, it follows an incremental approach to fix complex tasks into small sub-tasks known as modules. DevOps is an operational philosophy, which combines cultural practices and tools to achieve faster delivery.
The approach in Agile and DevOps: The agile model depends on Lean thinking that emphasizes constant iteration for incremental delivery. It is a collaboration between the development team and the end-users. DevOps is a mutual collaboration among the groups of development and operations, therefore the name. Merely working on software, it emphasizes the software and services to accelerate the delivery process.
The culture of Agile and DevOps: DevOps is the togetherness of cultural practices that increase the ability of an organization to deliver applications and services at a relatively quick pace. The development and operations teams work combinable as part of a DevOps team. On the contrary, <a href="agile-training" target="_blank" rel="noopener">Agile</a> is a modern approach that encourages change to development. Agile promotes smaller changes that may or may not lead to more significant changes over time.
Communication for Agile and DevOps: DevOps follows a modern documentation approach to communicate with relevant teams instead of conducting daily meetings. Agile, on the other hand, is a methodology revolves around a variety of formal/informal meetings are at the agile core. It believes in constant feedbacks and daily team meetings to make development teams more efficiently and productively.
Team Size for Agile and DevOps: DevOps believes in the number that means bigger the better; many teams work together as a single team to work on distinct theories. Agile on the other hand think in a small group, the faster they can deliver with fewer complexities.
Automation in Agile and DevOps: The automation of DevOps methodology is synonymous to maximize efficiency and minimize interruptions. Agile on the other hand also a modern approach to software development without anticipation.

<h3>Q6) What is Nagios Infrastructure?</h3>
Ans. Client-server architecture is the foundation of Nagios. A Nagios server is usually operating on a host in a network, and plugins are running on all distant computers that need to be monitored.
<ul>
<li style="font-weight: 400;" aria-level="1">The Nagios server contains the scheduler. The remote host receives a signal from this to start the plugins.</li>
<li style="font-weight: 400;" aria-level="1">The remote host provides the status of the plugin.</li>
<li style="font-weight: 400;" aria-level="1">The process scheduler receives the data from the plugin.</li>
<li style="font-weight: 400;" aria-level="1">The process scheduler changes the GUI and notifies administrators as well.</li>
</ul>
<h3>Q7) Explain the Nagios Plugins</h3>
Ans. Nagios Plugins are independent add-ons that Nagios Core can use to monitor virtually anything. The command-line parameters are processed by plugins, which then perform a particular check and submit the findings to Nagios Core.
Utilizing Nagios to monitor devices, hosts, protocols, applications, and services are made possible through plugins.
<h3><a id="nagios-ncpa"></a>Q8) What does Nagios' NCPA mean?</h3>
Ans:&nbsp;NCPA is referred to as Nagios Cross-Platform Agent. A plug-in for Nagios Core is available for download. Despite the fact that Nagios XI is not necessary for this agent, it does have a wizard for creating active checks with NCPA.
<h3><a id="nrpe"></a>Q9) Explain NRPE.</h3>
Ans:&nbsp;The Nagios Remote Plugin Executor, often known as NRPE, enables the use of remote Linux or UNIX workstations. With the aid of these plugins, remote workstations can be monitored for CPU and memory usage as if they were local resources. The NRPE agent is installed on distant devices for this purpose since it is required because this information is rarely publicly accessible to an external system.
Two components make up the NRPE add-on or plugin, and they cooperate to carry out the task:
<ul>
<li style="font-weight: 400;" aria-level="1">A local machine plugin used for monitoring is called check_nrpe.</li>
<li style="font-weight: 400;" aria-level="1">Runnable on distant machines is the NRPE daemon.</li>
</ul>
<h3>Q10) What different kinds of checks does Nagios perform on hosts and services?</h3>
Ans: There are two different sorts of checks that Nagios performs on hosts and services i.e. Active and Passive checks
<ul>
<li>Active Checks: The Nagios process starts active checks, which then run according to an established schedule. To monitor remote hosts and services, Nagios runs plugins and passes information about what needs to be examined.</li>
<li>Passive Checks: Applications and processes from outside sources start and carry out passive checks. The findings of the passive check are subsequently sent to Nagios for additional processing. Active checks are started and carried out by Nagios, whilst passive checks are carried out by external programs. This is the primary distinction between active and passive checks.</li>
</ul>
<h3>Q11) What is the Nagios protocol for sending passive checks?</h3>
Ans. To allow distant hosts to submit passive check results to the monitoring host, we may utilize the NSCA or NRDP addons. A daemon that operates on Nagios Core hosts and a client that runs on distant hosts make up the NSCA addon.
<h3><a id="soft-and-hard-states"></a>Q12) What do SOFT and HARD states entail?</h3>
Ans:&nbsp;Soft and hard states can be described as:
<ul>
<li style="font-weight: 400;" aria-level="1">Even if the service check has not been rechecked beyond the number of times set by the max check attempts directive, the results of the host or service checks in the event of the SOFT state are not OK or up to par. Soft Recovery is the process of recovering a component from such a soft error.</li>
<li style="font-weight: 400;" aria-level="1">Hard errors occur when a host or service check result is not "OK" and it has been tested more than the number of times allowed by the max check attempts directive in the host specification. Hard Recovery is the process of recovering any service from this problem.</li>
</ul>
