Is it a tool, framework or programming language?<\/strong><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">Answer: None of these! Simply saying, it\u2019s a blended word formed from two words, development and operations. Actually, it\u2019s the practice of collaborating development and operations teams in a software project in order to overcome organizational silos and to achieve improved productivity in delivering products and services as per customer need. <\/span><\/p>\n<p><b><\/b><span class=\"s1\">2. <strong>What can a DevOps Engineer do? <\/strong><\/span><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">Answer: The main objective for DevOps is to address some crucial challenges faced by development and operations teams in a traditional SDLC project. For developers, they may have to wait a lot before code deployment completion. Also, they may face troubles in managing old, new and pending codes at the same time. For the operations team, managing uptime will be the main issue. And for the operations team, there would be difficulty in handling less effective infrastructure management automation tools. DevOps can minimize these efforts.<\/span><\/p>\n<blockquote><p>Looking for Online Training Course for\u00a0AWS DevOps Engineer Professional?\u00a0Join <a href=\"https:\/\/www.whizlabs.com\/aws-devops-certification-training\/online-course\/\" target=\"_blank\" rel=\"noopener noreferrer\">AWS DevOps Engineer Professional Online Course<\/a> and start learning with the industry experts.<\/p><\/blockquote>\n<p><b><\/b><span class=\"s1\">3. <strong>How DevOps Collaborates Development &amp; Operations teams? <\/strong><\/span><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">Answer: This is one of the frequently asked DevOps Interview Questions in recent times. We\u2019ve discussed the common problems development and operations teams face. DevOps implements a \u201ccontinuous integration\u201d approach to faster deployment, testing, and feedback mechanism so as to eliminate waiting time for the software development team. For operations, DevOps have methods such as \u201ccontinuous monitoring\u201d, \u201cconfiguration management\u201d, \u201cvirtualization\u201d, etc. With all these methods, DevOps is buzzing towards a highly automated, standardized process with a handful of tools reducing the need for human intervention.<span class=\"Apple-converted-space\">\u00a0 \u00a0<\/span><\/span><\/p>\n<p><b><\/b><span class=\"s1\">4. <strong>What made you take the decision to become a DevOps engineer?<\/strong><\/span><\/p>\n<p class=\"p5\" style=\"text-align: justify;\"><span class=\"s1\">Answer: If you are making a career shift from an operations role into a DevOps engineer, this would be one of the pivotal DevOps interview questions you may face in a DevOps coding interview. Most of us may try to answer this question like this- \u201cDevelopment is my career goal and I had a strong desire to move here from long back\u201d. However, this isn\u2019t the right way to say. You should say like this \u2013 \u201cI want to see myself as part of an organization that has processes where engineering and operations teams are working smartly and productively than ever. And, it\u2019d be great if I could be part of the entire software delivery system from scratch to finish.<\/span><\/p>\n<p><b><\/b><span class=\"s1\">5. <strong>What are the prerequisites for the implementation of DevOps?<\/strong><\/span><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">Answer: Followings are the useful prerequisites for the implementation of DevOps &#8211;<\/span><\/p>\n<ul>\n<li>Proper communication across the team<\/li>\n<li>Commitment at the senior level<\/li>\n<li>Version Control Software<\/li>\n<li>Automated testing<\/li>\n<li>Automated tools for compliance<\/li>\n<li>Automated deployment<\/li>\n<\/ul>\n<p><b><\/b><span class=\"s1\">6. <strong>List out some of the most popular DevOps tools. Did you use any of these tools?<\/strong><\/span><\/p>\n<p>Answer: Here is the list of some most popular DevOps tools.<\/p>\n<ol class=\"ol2\" style=\"text-align: justify;\">\n<li class=\"li1\"><span class=\"s1\"><strong>Git &#8211;<\/strong>\u00a0It\u2019s a well-known DevOps tool used for distributed source code management. <\/span><\/li>\n<li class=\"li1\"><span class=\"s1\"><strong>Jenkins &#8211;<\/strong> This tool is a continuous integration tool that provides running tests on a non-developer machine when new code pushed into the source repository. <\/span><\/li>\n<li class=\"li1\"><span class=\"s1\"><strong>Puppet &#8211;<\/strong>\u00a0A cross-platform configuration management tool that can manage infrastructure as code.<\/span><\/li>\n<li class=\"li1\"><span class=\"s1\"><strong>Raygun &#8211;<\/strong>\u00a0This is a DevOps tool meant for error and crash reporting. <\/span><\/li>\n<li class=\"li1\"><span class=\"s1\"><strong>Docker &#8211;<\/strong>\u00a0Docker is a tool used at the time of its continuous deployment stage of DevOps to achieve containerization of OS and its dependencies. <\/span><\/li>\n<\/ol>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">Well, there\u2019re a lot of other tools out there. Here we just put some mentions. Try to find out more such tools to prepare more DevOps interview questions based on those. If you\u2019re experienced in DevOps, you\u2019d have some working knowledge in any of DevOps tools. But make sure that you\u2019re responding honestly while answering any of DevOps interview questions even the question seemed to be confusing. <\/span><\/p>\n<p><b><\/b><span class=\"s1\">7. <strong>What\u2019s the role of AWS in DevOps?<\/strong><\/span><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">Answer: Amazon Web Services (AWS) offers powerful features that support process automation and continuous delivery. On the other hand, DevOps provides unprecedented practices to grow an organization\u2019s capability to deliver products and services at a high pace. Undoubtedly, the blend of these two elements will have a huge impact on an organizations workflow. It\u2019ll automate manual tasks, allows teams to manage complex environments etc. <\/span><\/p>\n<p class=\"p5\" style=\"text-align: justify;\"><span class=\"s1\">So if you are opting for a DevOps engineer position that requires AWS skills, you may have to prepare for AWS DevOps interview questions. If you\u2019ve some prior AWS knowledge, many of the Amazon DevOps interview questions won\u2019t feel tough to you.<\/span><\/p>\n<p><span class=\"s1\">8. <strong>What are the most used scripting languages for DevOps?<\/strong><\/span><\/p>\n<p class=\"p4\"><span class=\"s1\">Answer: DevOps was a further step towards \u201cautomate all\u201d philosophy. That is &#8211; writing most of the infrastructure required for an organization in lines of code. We learned about IaaC scripts that are written in JSON or YAML. Moreover, template files required for DevOps infrastructure is also written in YAML while infrastructure deployment scripts in Python. Here, applications are written in JavaScript that is deployed through pipelines are written in Groovy.<span class=\"Apple-converted-space\">\u00a0 <\/span><\/span><\/p>\n<p class=\"p4\"><span class=\"s1\">Moving to the development side, we can see Python as the most used language here. Go, C, JavaScript, and Ruby are also recommended for DevOps programming.<\/span><\/p>\n<p><span class=\"s1\">9. <strong>DevOps and Agile: Are they synonymous or different items?<\/strong><\/span><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">Answer: Perhaps, it\u2019d be one of the confusing Amazon DevOps interview questions for the beginners. But once you understood the basics of these two, it won\u2019t be a troublesome case. We know DevOps as a software development culture that creates a collaborative environment across software development and operations teams in an organization. While DevOps is dealing with the collaboration across development and operations team, agile addresses issues within the software development team and the end users. This is the simple and fundamental difference.\u00a0<\/span><\/p>\n<p><span class=\"s1\">10. <strong>What is CI\/CD in DevOps?<\/strong><\/span><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">Answer: Continuous Integration (CI) in DevOps targets at collecting work from individual developers and put it into a central repository infrequent intervals as early as possible. This helps to detect integration bugs from the early stage of product development. <\/span><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">DevOps Continuous Delivery (CD) ensures the building, testing, and releasing of bug-free software into production line infrequent intervals by means of an automation system. This system verifies that the development team automates testing and deployment processes as well for making sure that the code is always in deployable\u00a0form.<\/span><\/p>\n<p><span class=\"s1\">11. <strong>Is DevOps Continuous Delivery and Continuous Deployment are the same?<\/strong><\/span><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">Answer: Even these terms look similar, they are distinct differences between these two. Continuous delivery aims at keeping the code base at a deployable stage at any time. This doesn\u2019t mean that the project is 100% done but it\u2019s successfully written, tested and debugged and can deploy at any time we want. <\/span><\/p>\n<p class=\"p5\" style=\"text-align: justify;\"><span class=\"s1\">Continuous deployment is a term that indicates the automatic deployment of development changes into the production environment. It\u2019s is often considered as the next step of continuous delivery. <\/span><\/p>\n<p><span class=\"s1\">12. <strong>Is testing necessary before production in a DevOps environment?<\/strong><\/span><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">Answer: A tech recruiter who\u2019s conducting DevOps interview questions may never want to hire a candidate for a DevOps position if the candidate still sticks on to the concept of information silos in an organization. The recruiter may expect you to know how DevOps concept benefits the entire process of IT projects in your organization. <\/span><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">So for this question, it is fine to answer like this &#8211; \u201cDevOps is all about carrying out continuous testing process from development to delivery where every member of the project shares the same responsibility. This will help to assure quality throughout the process utilizing the time of everyone in the most productive manner.\u201d<span class=\"Apple-converted-space\">\u00a0 \u00a0<\/span><\/span><\/p>\n<p><span class=\"s1\">13. <strong>What are CI Pipelines and DevOps Assembly Lines?<\/strong><\/span><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">Answer: In simple words, a pipeline is a set of jobs that are executed in several stages. If there are multiple jobs in a stage, they\u2019ll be executed in parallel. In a continuous integration (CI)\u00a0pipeline in DevOps, developers send the code they wrote into a repository for automated integration testing immediately after the code\u2019s produced. The code will be tested within minutes and developers get informed any errors occurred during testing. Then, the developer will re-work on the code and this process continues until the code is error-free. <\/span><\/p>\n<p class=\"p5\" style=\"text-align: justify;\"><span class=\"s1\">The intention of DevOps assembly lines is to connect and automate actions performed by several departments in a software development project. Configuration management and infrastructure provision is an operations activity. The responsibility of semantic versioning and approval gates are assigned to release managers. All these activities are part of a typical DevOps assembly line. CI pipeline itself is a subset of this assembly line. Altogether, DevOps assembly line can be called as a pipeline of pipelines.<\/span><\/p>\n<p><span class=\"s1\">14. <strong>What is IaaC and how is it implemented using AWS?<\/strong>\u00a0<\/span><\/p>\n<p class=\"p4\"><span class=\"s1\">Answer: Infrastructure as a Code (IaaC) or programmable infrastructure is a DevOps practice to\u00a0make infrastructure management process as easy, reliable, and fast. Amazon has a special service called AWS CloudFormation\u00a0that helps to set up your Amazon Web Services resources. This service allows using a single file to model, all resources needed for AWS applications to run for an account. <\/span><\/p>\n<p class=\"p4\"><span class=\"s1\">Here, we have to write a CloudFormation script that contains infrastructure details that need to be deployed, and AWS will take care of deploying as per our requirement. This script can be written on either JSON or YAML.<\/span><\/p>\n<blockquote><p>Other Helpful Resource: <a href=\"https:\/\/www.whizlabs.com\/blog\/aws-devops-engineer-professional-certification-preparation\/\" target=\"_blank\" rel=\"noopener noreferrer\">Preparation Guide for AWS DevOps Engineer Professional Exam<\/a><\/p><\/blockquote>\n<p><span class=\"s1\">15. <strong>Why we need Git in DevOps?<\/strong><\/span><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">Answer: Git is a tool to perform version control. It can be easily associated with DevOps ecosystem. Developers can use this tool to manage their code versions over time. Changes made to the code will incrementally stack up to the existing code creating a new version. Anyhow, it\u2019s possible to rollback to an earlier code version. One major feature of Git is its distributed structure so that the developers can work with an offline copy of the code base.<\/span><\/p>\n<p><span class=\"s1\">16. <strong>What are Anti-Patterns of DevOps?<\/strong><\/span><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">Answer: Anti-Patterns denotes the warning signals when our software team moving away from proper DevOps implementation. Here, they diminish the entire DevOps idea. Root Cause analysis, Information Silos, Human errors, Criticizing mentality, etc. are few examples of Anti-Patterns of DevOps. Let\u2019s take the \u2018Criticizing mentality\u2019 as a case. As you can imagine it\u2019s the culture of criticizing others for the mistake they made without taking consideration of a root cause analysis of the problem.\u00a0<\/span><\/p>\n<p><span class=\"s1\">17. <strong>Can DevOps be applied to the waterfall software development model?<\/strong><\/span><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">Answer: Surely, we can. But, it won\u2019t be a right move if we seriously want to save our companies\u2019 resources. We\u2019ll be surely able to optimize DevOps build processes by means of automation if we follow the waterfall approach. But in this case, no matter how faster we develop the code, it will not get end users until the next release cycle. The same is the case with DevOps operations side. This delay in product delivery will diminish even the core purpose of DevOps integration.\u00a0<\/span><\/p>\n<p><span class=\"s1\">18. <strong>What is the role of configuration management in DevOps?<\/strong><\/span><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">Answer: In software development, configuration management recapitulates the necessary items that are required for a successful project completion. Since DevOps spans across both development and operations faces of software creation, it requires a comprehensive configuration management plan to support it. There are 3 major elements in each configuration management in DevOps- A source code depository, An Artifact Repository, and a Configuration Management Database.<\/span><\/p>\n<p><span class=\"s1\">19. <strong>What is the &#8216;CHEF&#8217; tool used in DevOps?<\/strong><\/span><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">Answer: Chef is a popular configuration management tool used to control and manage the infrastructure of software production. It uses a pure-Ruby, domain-specific language for writing system configuration files in DevOps. As these files implement IaaC (Infrastructure as a Code) feature of DevOps, these can be easily tested and version controlled. Although this tool has an architecture almost similar to puppet tool, there\u2019s a special component in Chef that lacks in Puppet. It\u2019s an element called \u201cworkstation\u201d which acts as a middleman between users and the tool itself.<\/span><\/p>\n<p><span class=\"s1\">20. <strong>What do you know about DevOps Toolchain?<\/strong><\/span><\/p>\n<p class=\"p4\" style=\"text-align: justify;\"><span class=\"s1\">Answer: Here\u2019s the Last but not least among DevOps interview questions that can repeatedly ask during many DevOps interviews. A DevOps toolchain is simply referred to the set of tools that aid the movement of code through various stages of software development and production. Loosely, we can say that there are seven stages in DevOps lifecycle &#8211; Plan, Create, Verify, Packaging, Release, and Configure &amp; Monitor. Now, there isn\u2019t a single toolkit that\u2019s capable of performing these tasks. Anyhow for each of these tasks, there are specific tools available now.<\/span><\/p>\n<p>21. <strong>Explain pair programming in the DevOps?<\/strong><\/p>\n<p>Pair programming is an important part of the DevOps process. It helps developers to collaborate and code more efficiently. Pair programming is when two developers work together on the same code. One developer writes the code while the other developer reviews it. This way, the two developers can catch any errors and make sure the code is of high quality. This is a great way to improve collaboration among developers. It also helps to improve the quality of the code.<\/p>\n<p><span style=\"font-weight: 400;\">22. <strong>Which makes AWS DevOps to be highly accessible?<\/strong><\/span><\/p>\n<p>The answer is simple: automation.<\/p>\n<p>AWS DevOps is highly accessible because it automates many of the tasks that would otherwise be manual, time-consuming, and error-prone. For example, AWS DevOps can automatically provision and configure AWS resources, deploy applications, and monitor them for you. This means that you can focus on your core business tasks and leave the DevOps to us.<\/p>\n<p>In addition, AWS DevOps is designed to be highly scalable so that you can easily add or remove resources as your needs change. This makes it easy to keep your environment up-to-date and running smoothly, even as your business grows.<\/p>\n<p><span style=\"font-weight: 400;\">23. <strong>What are the various DevOps-related job roles?<\/strong><\/span><\/p>\n<p>There are various job roles in DevOps, such as:<\/p>\n<p>1. Development team &#8211; responsible for coding and testing the software.<\/p>\n<p>2. Operations team &#8211; responsible for deploying and maintaining the software.<\/p>\n<p>3. Release manager &#8211; responsible for managing the software release process.<\/p>\n<p>4. Configuration manager &#8211; responsible for managing the software configuration.<\/p>\n<p>5. Monitoring team &#8211; responsible for monitoring the software and the infrastructure.<\/p>\n<p><span style=\"font-weight: 400;\">24. <strong>Mention the areas that DevOps automation has been implemented?<\/strong><\/span><\/p>\n<p>There are a number of areas where DevOps automation can be implemented, including continuous integration, delivery and deployment.Automating these processes can help to improve efficiency and quality, while also reducing the risks associated with manual processes.<\/p>\n<p>Some of the other areas where DevOps automation can be used include configuration management, monitoring and logging. By automating these processes, organizations can gain greater insights into their systems and identify potential issues before they cause problems.<\/p>\n<p>Implementing DevOps automation can be a challenge, but there are a number of tools and services that can help. Here are just a few examples:<\/p>\n<p>* Jenkins: A popular open source automation server that can be used for a range of tasks, including building, testing and deploying software.<\/p>\n<p>* Bamboo: A commercial automation server from Atlassian that offers similar functionality to Jenkins.<\/p>\n<p>* Travis CI: A popular open source continuous integration service that can be used to automate the building, testing and deploying of software.<\/p>\n<p>* CircleCI: A commercial continuous integration and delivery platform that offers similar functionality to Travis CI.<\/p>\n<p>Organizations should also consider their specific needs when choosing a DevOps automation tool or service. There is no one-size-fits-all solution, so it&#8217;s important to select a tool or service that will work well for your particular environment and requirements.<\/p>\n<p><span style=\"font-weight: 400;\">25. <strong>How does VCS works in DevOps?<\/strong><\/span><\/p>\n<p>In DevOps, VCS is used to manage code changes and track changes over time. It allows developers to collaborate on code, share changes, and track progress. VCS also provides a way to roll back changes if necessary.<\/p>\n<p>26. <strong>How will you approach a project that needs to deploy DevOps?<\/strong><\/p>\n<p><span style=\"font-weight: 400;\">There are a few key things to keep in mind when approaching a project that needs to deploy DevOps. The<strong> first is to ensure that the development and operations teams are aligned from the start<\/strong>. This means clear communication and collaboration between the two teams from the very beginning.The <strong>second key thing<\/strong> to keep in mind is <strong>automation<\/strong>. Automation is key to successful DevOps deployments. Everything from the build process to the deployment process should be automated as much as possible. This will help to speed up the process and make it more efficient.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The <strong>third key thing<\/strong> to keep in mind is <strong>testing<\/strong>. Testing is essential to ensure that the code and the application are working as intended. This includes both functional and non-functional testing.<\/span><\/p>\n<p>27. <strong>What are the three important KPIs of DevOps?<\/strong><\/p>\n<p><span style=\"font-weight: 400;\">There are a lot of KPIs (Key Performance Indicators) that can be used to measure the success of a DevOps team. However, there are three KPIs that are particularly important in assessing the performance of a DevOps team.<\/span><\/p>\n<ul>\n<li><span style=\"font-weight: 400;\">The first KPI is the lead time. Lead time is the time it takes from when a customer request is made to when it is actually fulfilled. A shorter lead time indicates a better able DevOps team that can deliver customer requests faster.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">The second KPI is the number of defects. A lower number of defects indicates a more stable and efficient system that is less likely to break down.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">The third KPI is the mean time to repair. This is the time it takes to fix a defect once it is discovered. A shorter mean time to repair indicates a more responsive DevOps team that can fix problems quickly.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">These three KPIs are important in assessing the performance of a DevOps team because they indicate the team&#8217;s ability to deliver customer requests quickly, efficiently, and with fewer defects.<\/span><\/p>\n<p>28. <strong>What are the benefits of usage of version control?<\/strong><\/p>\n<p><span style=\"font-weight: 400;\">Most people are familiar with the benefits of version control for software development, but there are many other potential uses for version control systems. Here are just a few examples:<\/span><\/p>\n<ul>\n<li><span style=\"font-weight: 400;\"> Documenting changes to a project over time<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Coordinating work on a shared project<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Keeping track of configuration changes<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Managing website content<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Minimises duplication of outdated versions of any document\u00a0<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">The possibilities are really endless. In general, version control can be a huge help in any situation where you need to track changes or manage multiple versions of something.<\/span><\/p>\n<p>29. <strong>What are the differences between git pull and git fetch?<\/strong><\/p>\n<p><span style=\"font-weight: 400;\">There are two main ways to get the latest code from a remote repository: git pull and git fetch. Both of these commands will retrieve the code from the remote repository, but they differ in how they handle the code that is retrieved.<\/span><\/p>\n<p><span style=\"font-weight: 400;\"><strong>Git pull<\/strong> will not only retrieve the code from the remote repository, but it will also try to merge the code into the current branch. This can cause problems if there are any conflicts between the code in the remote repository and the code in the current branch.<\/span><\/p>\n<p><span style=\"font-weight: 400;\"><strong>Git fetch<\/strong> will retrieve the code from the remote repository, but it will not try to merge the code. This means that you will have to manually merge the code if you want to incorporate the changes from the remote repository.<\/span><\/p>\n<p>30. <strong>What are the key elements of continuous testing tools?<\/strong><\/p>\n<p><span style=\"font-weight: 400;\">There are a few key elements that you should look for when choosing a continuous testing tool. And they are:<\/span><\/p>\n<ul>\n<li><span style=\"font-weight: 400;\">Risk assessment\u00a0<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Policy analysis<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Requirements traceability<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Advanced analysis<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Test optimization<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Service virtualization\u00a0<\/span><\/li>\n<\/ul>\n<p>31. <strong>Explain the concept of branching in Git.<\/strong><\/p>\n<p><span style=\"font-weight: 400;\">Git is a distributed version control system, which means that each developer has a complete copy of the project history on their own machine. When a change is made, it is committed to the local repository, and then pushed to the remote repository.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The process of branching allows developers to create a new line of development, which can be used to add new features, fix bugs, or experiment without affecting the main codebase.
