Q31). Explain your understanding of both the software development side and technical operations side of an organization you have worked in the past recently.

Ans:- The answer to this question may vary from person to person. Here, you should discuss the experience of how flexible you were in your last Company.

32). Why DevOps has become famous?

Ans:- These days, the market window of products has reduced drastically. We see new products almost daily. This provides a myriad of choices to consumers but it comes at a cost of heavy competition in the market. Organizations cant afford to release big features after a gap. They tend to ship off small features as releases to the customers at regular intervals so that their products don't get lost in this sea of competition.

Customer satisfaction is now a motto to the organizations which has also become the goal of any product for its success. In order to achieve this, companies need to do the below things:

  • Frequent feature deployments
  • Reduce time between bug fixes
  • Reduce failure rate of releases
  • Quicker recovery time in case of release failures.
  • In order to achieve the above points and thereby achieving seamless product delivery, DevOps culture acts as a very useful tool. Due to these advantages, multi-national companies like Amazon and Google have adopted the methodology which has resulted in their increased performance.

Q33). What is the use of SSH?

Ans:-  SSH stands for Secure Shell and is an administrative protocol that lets users have access and control the remote servers over the Internet to work using the command line.

SSH is a secured encrypted version of the previously known Telnet which was unencrypted and not secure. This ensured that the communication with the remote server occurs in an encrypted form.

SSH also has a mechanism for remote user authentication, input communication between the client and the host, and sending the output back to the client.

Q34). What is Configuration management?

Ans:-  Configuration management (CM) is basically a practice of systematic handling of the changes in such a way that system does not lose its integrity over a period of time. This involves certain policies, techniques, procedures, and tools for evaluating change proposals, managing them, and tracking their progress along with maintaining appropriate documentation for the same.

CM helps in providing administrative and technical directions to the design and development of the appreciation.

Q35). What is the importance of having configuration management in DevOps?

Ans:-  Configuration management (CM) helps the team in the automation of time-consuming and tedious tasks thereby enhancing the organization’s performance and agility.

It also helps in bringing consistency and improving the product development process by employing means of design streamlining, extensive documentation, control, and change implementation during various phases/releases of the project.

Q36). What does CAMS stand for in DevOps?

Ans:-  CAMS stands for Culture, Automation, Measurement, and Sharing. It represents the core deeds of DevOps.

Q37). What is Continuous Integration (CI)?

Ans:-  Continuous Integration (CI) is a software development practice that makes sure developers integrate their code into a shared repository as and when they are done working on the feature. Each integration is verified by means of an automated build process that allows teams to detect problems in their code at a very early stage rather than finding them after the deployment.

  • Developers regularly check out code into their local workspaces and work on the features assigned to them.
  • Once they are done working on it, the code is committed and pushed to the remote shared repository which is handled by making use of effective version control tools like git.
  • The CI server keeps track of the changes done to the shared repository and it pulls the changes as soon as it detects them.
  • The CI server then triggers the build of the code and runs unit and integration test cases if set up.
  • The team is informed of the build results. In case of the build failure, the team has to work on fixing the issue as early as possible, and then the process repeats.

Q38). Why is Continuous Integration needed?

Ans:-  By incorporating Continuous Integration for both development and testing, it has been found that the software quality has improved and the time taken for delivering the features of the software has drastically reduced.

This also allows the development team to detect and fix errors at the initial stage as each and every commit to the shared repository is built automatically and run against the unit and integration test cases.

Q39). What is Continuous Testing (CT)?

Ans:- Continuous Testing (CT) is that phase of DevOps which involves the process of running the automated test cases as part of an automated software delivery pipeline with the sole aim of getting immediate feedback regarding the quality and validation of business risks associated with the automated build of code developed by the developers.

Using this phase will help the team to test each build continuously (as soon as the code developed is pushed) thereby giving the dev teams a chance to get instant feedback on their work and ensuring that these problems don’t arrive in the later stages of SDLC cycle.

Doing this would drastically speed up the workflow followed by the developer to develop the project due to the lack of manual intervention steps to rebuild the project and run the automated test cases every time the changes are made.

Q40) . What are the three important DevOps KPIs?

Ans:-  Few KPIs of DevOps are given below:

  • Reduce the average time taken to recover from a failure.
  • Increase Deployment frequency in which the deployment occurs.
  • Reduced Percentage of failed deployments.

Q41). Explain the different phases in DevOps methodology.

Ans:-  DevOps mainly has 6 phases and they are:


This is the first phase of a DevOps lifecycle that involves a thorough understanding of the project to ultimately develop the best product. When done properly, this phase gives various inputs required for the development and operations phases. This phase also helps the organization to gain clarity regarding the project development and management process.

Tools like Google Apps, Asana, Microsoft teams, etc are used for this purpose.


The planning phase is followed by the Development phase where the project is built by developing system infrastructure, developing features by writing codes, and then defining test cases and the automation process. Developers store their codes in a code manager called remote repository which aids in team collaboration by allowing view, modification, and versioning of the code.

Tools like git, IDEs like the eclipse, IntelliJ, and technological stacks like Node, Java, etc are used.

Continuous Integration (CI):

This phase allows for automation of code validation, build, and testing. This ensures that the changes are made properly without development environment errors and also allows the identification of errors at an initial stage.

Tools like Jenkins, circleCI, etc are used here.


DevOps aids in the deployment automation process by making use of tools and scripts which has the final goal of automating the process by means of feature activation. Here, cloud services can be used as a force that assists in upgrade from finite infrastructure management to cost-optimized management with the potential to infinite resources.

Tools like Microsoft Azure, Amazon Web Services, Heroku, etc are used.


This phase usually occurs throughout the lifecycle of the product/software due to the dynamic infrastructural changes. This provides the team with opportunities for increasing the availability, scalability, and effective transformation of the product.

Tools like Loggly, BlueJeans, Appdynamics, etc are used commonly in this phase.


Monitoring is a permanent phase of DevOps methodology. This phase is used for monitoring and analyzing information to know the status of software applications.

Tools like Nagios, Splunk, etc are commonly used.

Q42) . How is DevOps different than the Agile Methodology?

Ans:- DevOps is a practice or a culture that allows the collaboration of the development team and the operations team to come together for successful product development. This involves making use of practices like continuous development, integration, testing, deployment, and monitoring of the SDLC cycle.

DevOps tries to reduce the gap between the developers and the operations team for the effective launch of the product.

Agile is nothing but a software development methodology that focuses on incremental, iterative, and rapid releases of software features by involving the customer by means of feedback. This methodology removes the gap between the requirement understanding of the clients and the developers.

Q43) . What can you say about antipatterns of DevOps?

Ans:- A pattern is something that is most commonly followed by large masses of entities. If a pattern is adopted by an organization just because it is being followed by others without gauging the requirements of the organization, then it becomes an anti-pattern. Similarly, there are multiple myths surrounding DevOps which can contribute to antipatterns, they are:

  • DevOps is a process and not a culture.
  • DevOps is nothing but Agile.
  • There should be a separate DevOps group.
  • DevOps solves every problem.
  • DevOps equates to developers running a production environment.
  • DevOps follows Development-driven management
  • DevOps does not focus much on development.
  • As we are a unique organization, we don’t follow the masses and hence we won’t implement DevOps.
  • We don’t have the right set of people, hence we cant implement DevOps culture.

Q44). Can you tell me something about Memcached?

Ans:-  Memcached is an open-source and free in-memory object caching system that has high performance and is distributed and generic in nature. It is mainly used for speeding the dynamic web applications by reducing the database load.

Memcached can be used in the following cases:

  • Profile caching in social networking domains like Facebook.
  • Web page caching in the content aggregation domain.
  • Profile tracking in Ad targeting domain.
  • Session caching in e-commerce, gaming, and entertainment domain.
  • Database query optimization and scaling in the Location-based services domain.

Benefits of Memcached:

  • Using Memcached speeds up the application processes by reducing the hits to a database and reducing the I/O access.
  • It helps in determining what steps are more frequently followed and helps in deciding what to cache.

Some of the drawbacks of using Memcached are:

  • In case of failure, the data is lost as it is neither a persistent data store nor a database.
  • It is not an application-specific cache.
  • Large objects cannot be cached.

Q45). What are the various branching strategies used in the version control system?

Ans:- Branching is a very important concept in version control systems like git which facilitates team collaboration. Some of the most commonly used branching types are:

Feature branching

  • This branching type ensures that a particular feature of a project is maintained in a branch.
  • Once the feature is fully validated, the branch is then merged into the main branch.

Task branching

  • Here, each task is maintained in its own branch with the task key being the branch name.
  • Naming the branch name as a task name makes it easy to identify what task is getting covered in what branch.

Release branching

  • This type of branching is done once a set of features meant for a release are completed, they can be cloned into a branch called the release branch. Any further features will not be added to this branch.
  • Only bug fixes, documentation, and release-related activities are done in a release branch.
  • Once the things are ready, the releases get merged into the main branch and are tagged with the release version number.
  • These changes also need to be pushed into the develop branch which would have progressed with new feature development.

The branching strategies followed would vary from company to company based on their requirements and strategies.

Q46). Can you list down certain KPIs which are used for gauging the success of DevOps?

Ans:-  KPIs stands for Key Performance Indicators. Some of the popular KPIs used for gauging the success of DevOps are:

  • Application usage, performance, and traffic
  • Automated Test Case Pass Percentage.
  • Application Availability
  • Change volume requests
  • Customer tickets
  • Successful deployment frequency and time
  • Error/Failure rates
  • Failed deployments
  • Meantime to detection (MTTD)
  • Meantime to recovery (MTTR)

Q47). What is CBD in DevOps?

Ans:-  CBD stands for Component-Based Development. It is a unique way for approaching product development. Here, developers keep looking for existing well-defined, tested, and verified components of code and relieve the developer of developing from scratch.

Q48). What is Resilience Testing?

Ans:-  Resilience Testing is a software process that tests the application for its behavior under uncontrolled and chaotic scenarios. It also ensures that the data and functionality are not lost after encountering a failure.

Q49) . Can you say something about the DevOps pipeline?

Ans:-  A pipeline, in general, is a set of automated tasks/processes defined and followed by the software engineering team. DevOps pipeline is a pipeline which allows the DevOps engineers and the software developers to efficiently and reliably compile, build and deploy the software code to the production environments in a hassle free manner.

Q50) . Who is a DevOps engineer?

Ans:-  A DevOps engineer is a person who works with both software developers and the IT staff to ensure smooth code releases. They are generally developers who develop an interest in the deployment and operations domain or the system admins who develop a passion for coding to move towards the development side.

In short, a DevOps engineer is someone who has an understanding of SDLC (Software Development Lifecycle) and of automation tools for developing CI/CD pipelines.

Q51). What are the advantages of DevOps?

Ans:-  For this answer, you can use your past experience and explain how DevOps helped you in your previous job. If you don’t have any such experience, then you can mention the below advantages.

Technical benefits:

  • Continuous software delivery
  • Less complex problems to fix
  • Faster resolution of problems

Business benefits:

  • Faster delivery of features
  • More stable operating environments
  • More time available to add value (rather than fix/maintain)

Q52) . Mention some of the core benefits of DevOps?


  • Faster development of software and quick deliveries.
  • DevOps methodology is flexible and adaptable to changes easily.
  • Compared to the previous software development models confusion about the project is decreased due to which the product quality is increased.
  • The gap between the development team and operation team is bridged. i.e, the communication between the teams has been increased.
  • Efficiency is increased by the addition of automation of continuous integration and continuous deployment.
  • Customer satisfaction is enhanced.

Q53). What is the most important thing DevOps helps us achieve?

Ans:-  The most important thing that DevOps helps us achieve is to get the changes into production as quickly as possible while minimizing risks in software quality assurance and compliance. This is the primary objective of DevOps. 

However, you can add many other positive effects of DevOps. For example, clearer communication and better working relationships between teams i.e. both the Ops team and Dev team collaborate together to deliver good quality software which in turn leads to higher customer satisfaction.

Q54) . Explain with a use case where DevOps can be used in industry/ real-life.

Ans:-  There are many industries that are using DevOps so you can mention any of those use cases, you can also refer the below example:

Etsy is a peer-to-peer e-commerce website focused on handmade or vintage items and supplies, as well as unique factory-manufactured items. Etsy struggled with slow, painful site updates that frequently caused the site to go down. It affected sales for millions of Etsy’s users who sold goods through online market place and risked driving them to the competitor.

With the help of a new technical management team, Etsy transitioned from its waterfall model, which produced four-hour full-site deployments twice weekly, to a more agile approach. Today, it has a fully automated deployment pipeline, and its continuous delivery practices have reportedly resulted in more than 50 deployments a day with fewer disruptions.

Q55). Explain your understanding and expertise on both the software development side and the technical operations side of an organization you have worked with in the past.

Ans:-  For this answer, share your past experience and try to explain how flexible you were in your previous job. You can refer the below example:

DevOps engineers almost always work in a 24/7 business-critical online environment. I was adaptable to on-call duties and was available to take up real-time, live-system responsibility. I successfully automated processes to support continuous software deployments. I have experience with public/private clouds, tools like Chef or Puppet, scripting and automation with tools like Python and PHP, and a background in Agile.

Q56) . What are the anti-patterns of DevOps?

Ans:-  A pattern is common usage usually followed. If a pattern commonly adopted by others does not work for your organization and you continue to blindly follow it, you are essentially adopting an anti-pattern. There are myths about DevOps. Some of them include:

  • DevOps is a process
  • Agile equals DevOps?
  • We need a separate DevOps group
  • Devops will solve all our problems
  • DevOps means Developers Managing Production
  • DevOps is Development-driven release management
  1. DevOps is not development driven.
  2. DevOps is not IT Operations driven.
  • We can’t do DevOps – We’re Unique
  • We can’t do DevOps – We’ve got the wrong people

Q57) . Explain the different phases in DevOps methodology?

Ans:-  The various phases of the DevOps lifecycle are as follows:

  • Plan – In this stage, all the requirements of the project and everything regarding the project like time for each stage, cost, etc are discussed. This will help everyone in the team to get a brief idea about the project.
  • Code – The code is written over here according to the client’s requirements. Here codes are written in the form of small codes called units.
  • Build – Building of the units is done in this step.
  • Test – Testing is done in this stage and if there are mistakes found it is returned for re-build.
  • Integrate – All the units of the codes are integrated into this step.
  • Deploy – codeDevOpsNow is deployed in this step on the client’s environment.
  • Operate – Operations are performed on the code if required.
  • Monitor – Monitoring of the application is done over here in the client’s environment.

Q58). Explain your understanding and expertise on both the software development side and the technical operations side of an organization you have worked with in the past?


  • Deployment frequency: This measures how frequently a new feature is deployed.
  • Change failure rate: This is used to measure the number of failures in deployment.
  • Mean Time to Recovery (MTTR): The time is taken to recover from a failed deployment.

Q59). What are the KPIs that are used for gauging the success of a DevOps team?

Ans:- KPI Means Key Performance Indicators are used to measure the performance of a DevOps team, identify mistakes and rectify them. This helps the DevOps team to increase productivity and which directly impacts revenue.

There are many KPIs which one can track in a DevOps team. Following are some of them:

  • Change Failure rates: This is used to measure the number of failures in deployments.
  • Meantime to recovery (MTTR): The time is taken to recover from a failed deployment.
  • Lead time: This helps to measure the time taken to deploy on the production environment.
  • Deployment frequency: This measures how frequently a new feature is deployed.
  • Change volume: This is used to measure how much code is changed from the existing code.
  • Cycle time: This is used to measure total application development time.
  • Customer Ticket: This helps us to measure the number of errors detected by the end-user.
  • Availability: This is used to determine the downtime of the application.
  • Defect escape rate: This helps us to measure the number of issues that are needed to be detected as early as possible.
  • Time of detection: This helps you understand whether your response time and application monitoring processes are functioning correctly.

Q60). Why has DevOps become famous?

Ans:- As we know before DevOps there are two other software development models:

  • Waterfall model
  • Agile model

In the waterfall model, we have limitations of one-way working and lack of communication with customers. This was overcome in Agile by including the communication between the customer and the company by taking feedback. But in this model, another issue is faced regarding communication between the Development team and operations team due to which there is a delay in the speed of production. This is where DevOps is introduced. It bridges the gap between the development team and the operation team by including the automation feature. Due to this, the speed of production is increased. By including automation, testing is integrated into the development stage. Which resulted in finding the bugs at the very initial stage which increased the speed and efficiency.

Q61). How does AWS contribute to DevOps?

Ans:-  AWS [Amazon Web Services ] is one of the famous cloud providers. In AWS DevOps is provided with some benefits:

  • Flexible Resources: AWS provides all the DevOps resources which are flexible to use.
  • Scaling: we can create several instances on AWS with a lot of storage and computation power.
  • Automation: Automation is provided by AWS like CI/CD
  • Security: AWS provides security when we create an instance like IAM

DevOps Interview Questions and Answers for Advanced DevOps Professionals

In this section, we will be discussing interview questions for experienced people having more than three years of experience. Before you go through questions directly, take this quiz first to become a little more confident in your skills.

Q31). What are the anti-patterns in DevOps?

Ans:- A pattern is used by others, not by organizations and you continue blindly following it. You are essentially adopting anti-patterns here.

Q32). What is a Git Repository?

Ans:- It is a version control system that tracks changes to a file and allows you to revert to any particular changes.

Q33). In Git, how to revert a commit that has already been made public?

Ans:- Remove or fix the commit and push it to the remote repository. This is the most natural style to fix an error. To do this, you should use the command given below: Git commit –m “commit message”

Create a new commit that undergoes all changes that were made in the bad commit. Git revert

Q34). What is the process to squash last N number of commits into a single commit?

Ans:- There are two options to squash last N number of commits into a single commit.

  • To write a new commit message from scratch, you should use the following command: git reset –soft HEAD ~N && git commit
  • To edit the existing message, you should extract those messages first and pass them to the Git commit for later usage. Git reset –soft HEAD ~ N&& git commit –edit –m “$(git log –format=%B –reverse .HEAD {N})”

Q35). What is Git rebase and how to use it for resolving conflicts in a feature branch before merging?

Ans:- Git Rebase is a command that is used to merge another branch to the existing branch where you are working recently. It moves all local commits at the top of the history of that branch. It effectively replays the changes of feature branch at the tip of master and allows conflicts to be resolved in the process. Moreover, the feature branch can be merged to the master branch with relative ease and sometimes considered as the fast-forward operation.

Q36). How can you configure a git repository to run code sanity checking tools right before making commits and preventing them if the test fails?

Ans:-Sanity or smoke test determines how to continue the testing reasonably. This is easy configuring a Git repository to run code sanity checking before making commits and preventing them if the test fails. It can be done with a simple script as mentioned below:

#!/bin/sh file=$(git diff -cached -name-only -diff-filter=ACM | grep '.go$') if [ -z file]; then exit 0 fi unfmtd=$(gofmt -I $files) if [ -z unfmtd]; then exit 0 fi eacho "some .go files are not fmt'd" exit 1

Q37). How to find a list of files that are changed in a certain manner?

Q70). What is Memcached in DevOps?

Ans:-Memcached is an open source, high speed, distributed memory object. Its primary objective is enhancing the response time of data that can otherwise be constructed or recovered from another source of the database. It avoids the need for operating SQL database repetitively to fetch data for a concurrent request.

Q71). Why is Memcached useful?


  • It speeds up the application processes.
  • It determines what to store and share.
  • It reduces the total number of retrieval requests to the database.
  • It cuts the I/O access from the hard disk.

Q72). What are the drawbacks of Memcached?


  • It is not a persistent data store
  • It is not a database.
  • It is not application-specific.
  • It is not able to cache large objects.

Q73). What are the features of Memcached?

Ans:-A few highlighted features of Memcached can be given as:

  • Callbacks to simplify the code.
  • GetDelayed to reduce the response or wait time for the outcome.
  • A binary protocol to use with the new client.
  • An Igbinary data option is available to use with the complex data.

Q74). Can you share a single instance of Memcached with multiple instances?

Ans:-Yes, it is possible.

Q75). If you have multiple Memcached servers and one of the Memcached servers fails, then what will happen?

Ans:-Even if one of the Memcached servers fails, data won’t get lost, but it can be recovered by configuring it for multiple nodes.

Read: Periodic Table Of DevOps Tools - A Revolutionary Breakthrough

Q76). How to minimize the Memcached server outages?


  • If one of the server instances fails, it will put a huge load on the database server. To avoid this, the code should be written in such a way that it can minimize the cache stampedes and leave a minimal impact on the database server.
  • You can bring up an instance of Memcached on a new machine with the help of lost IP addresses.
  • You can modify the Memcached server list to minimize the server outages.
  • Set up the timeout value for Memcached server outages. If the server gets down, it will try to send a request to the client until the timeout value is achieved.

Q77). How to update Memcached when data changes?

Ans:-To update the Memcached in case of data changes, you can use these two techniques:

  • Clear the cache proactively
  • Reset the Cache

Q78). What is a Dogpile effect and how to prevent it?

Ans:-Dogpile effect refers to the event when the cache expires, and the website hits by multiple requests together at the same time. The semaphore lock can minimize this effect.  When the cache expires, the first process acquires the lock and generates new value as required.

Q79). Explain when Memcached should not be used?

  • It should not be used as a datastore but a cache only.
  • It should not be taken as the only source of information to run your apps, but the data should be available through other sources too.
  • It is just a value store or a key and cannot perform a query or iterate over contents to extract the information.
  • It does not offer any security for authentication or encryption.

Q80). What is the significance of the blue/green color in the deployment pattern?

Ans:-These two colors are used to represent tough deployment challenges for a software project. The live environment is the Blue environment. When the team prepares the next release of the software, it conducts the final stage of testing in the Green environment.

Q134). Can you tell me the advantages of using Git?


  • Data redundancy and replication
  • High availability
  • Only one Git directory per repository
  • Superior disk utilization and network performance
  • Collaboration friendly
  • Can be used for any sort of projects

Q135). Are git fetch and git pull the same?

Ans:-The command ‘git pull’ pulls any new commits from a branch from the central repository and then updates the target branch in the local repository.

But, ‘git fetch’ is a slightly different form of ‘git pull’. Unlike ‘git pull’, it pulls all new commits from the desired branch and then stores them in a new branch in the local repository.

Q136) . What are the benefits of using version control?


  • It helps improve the collaborative work culture: Here, team members are allowed to work freely on any file at any time. The version control system allows us to merge all changes into a common version.
  • It keeps different versions of code files securely: All the previous versions and variants of code files are neatly packed up inside the version control system.
  • It understands what happened: Every time we save a new version of our project, the version control system asks us to provide a short description of what was changed. More than that it allows us to see what changes were made in the file’s content, as well as who has made those changes.
  • It keeps backup: A distributed version control system like Git allows all team members to have the complete history of the project file so that in case there is a breakdown in the central server, they can use any of their teammate’s local Git repository. 

Q137). How do you handle the merge conflicts in Git?

Ans:- In order to resolve the merge conflicts in Git, we need to follow three steps:

  • Understand what happened: It could be because of the same line edit on the same file; it could be because of deleting some files, or also it could be because of files with the same file names. You can check everything by using ‘git status’.
  • Mark and clean up the conflict: When we open the files using the merge tool, Git marks the conflicted area like this ‘<<<<< HEAD’ and ‘ >>>>> [other/branch/name]’.
  • Perform commit again and then merge the current branch with the master branch.

Must-Know: Regression Testing Interview Questions and Answers.

Q138). Can you tell me some advantages of Forking Workflow over other Git workflows?

Ans:- Forking Workflow is fundamentally different from other Git workflows. Instead of using a single server-side repository to act as the ‘central’ codebase, Forking Workflow gives every developer their own server-side repositories. This workflow is most often seen in public open-source projects.

The main advantage is that contributions can be integrated without the need for everyone to push to a single central repository to maintain clean project history. Developers can push to their own server-side repositories, and only the project maintainer will push to the official repository.

As soon as developers are ready to publish their local commits, they will push their commits to their own public repositories. Then, they will perform a pull request from the main repository, which notifies the project maintainer that an update is ready to be integrated.

Q139). When do you use ‘git rebase’ instead of ‘git merge’?

Ans:- Both ‘git rebase’ and ‘git merge’ commands are designed to integrate changes from one branch into another branch: just that they just do it in different ways.

When we perform rebase of a feature branch onto the master branch, we move the base of the feature branch to the master branch’s ending point.

By performing a merge, we take the contents of the feature branch and integrate them with the master branch. As a result, only the master branch is changed, but the feature branch history remains the same. Merging adds a new commit to your history.

Rebasing will create inconsistent repositories. For individuals, rebasing makes a lot of sense. Now, in order to see the history completely, the same way as it has happened, we should use merge. Merge preserves history, whereas rebase rewrites it.

Q140) What is Continuous Testing and Automation Testing are?

Ans:- Automation testing, as the name suggests, is a process of automating the manual process of testing. It involves the use of separate testing tools that let developers create test scripts that can be executed repeatedly without any manual intervention.

Continuous testing is nothing but the process of executing automated tests as part of the software delivery pipeline in DevOps. In this process, each build is tested continuously, allowing the development team to get fast business feedback so that it can prevent the problems from progressing to the next stage of the software delivery lifecycle. This will dramatically speed up a developer’s workflow. He/she no longer needs to manually rebuild the project and re-run all tests after making changes.

Q145). How will you secure Jenkins?

Ans:- The way to secure Jenkins is as follows:

  • Ensure that the global security is on
  • Check whether Jenkins is integrated with the company’s user directory with an appropriate plugin
  • Make sure that Project matrix is enabled to fine-tune access
  • Automate the process of setting rights or privileges in Jenkins with a custom version-controlled script
  • Limit physical access to Jenkins data or folders
  • Periodically run security audits

Q146). How to create a backup and copy files in Jenkins?

Ans:- To create a backup, all we need to do is to periodically back up our JENKINS_HOME directory. This contains all of the build configurations of our job, our slave node configurations, and our build history. To create a backup of our Jenkins setup, just copy this directory. We can also copy a job directory to clone or replicate a job or rename the directory.

Q147). What is Jenkins Pipeline and CI/CD Pipeline?

Ans:- Jenkins Pipeline can be defined as a suite of plugins supporting both implementation and integration of Jenkins continuous delivery pipeline.

Continuous integration or continuous delivery pipeline consists of build, deploy, test, and release. The pipeline feature is very time-saving. In other words, a pipeline is a group of build jobs that are chained and integrated in a sequence.

Q148). What are Puppet Manifests?

Ans:- Every Puppet Node or Puppet Agent has got its configuration details in Puppet Master, written in the native Puppet language. These details are written in a language that Puppet can understand and are termed as Puppet Manifests. These manifests are composed of Puppet codes, and their filenames use the .pp extension.

For instance, we can write a manifest in Puppet Master that creates a file and installs Apache on all Puppet Agents or slaves that are connected to the Puppet Master.

Q149). How can I configure systems with Puppet?

Ans:- In order to configure systems with Puppet in a client or server architecture, we have to use the Puppet Agent and the Puppet Master applications. In a stand-alone architecture, we have to use the Puppet apply application.

Check out the most important Git Interview Questions and Answers now!

Q150). What is a Puppet Module? How is it different from the Puppet Manifest?

Ans:- A Puppet Module is nothing but a collection of manifests and data (e.g., facts, files, and templates). Puppet Modules have a specific directory structure. They are useful for organizing the Puppet code because with Puppet Modules we can split the Puppet code into multiple manifests. It is considered as the best practice to use Puppet Modules to organize almost all of your Puppet Manifests.

Puppet Modules are different from Puppet Manifests. Manifests are nothing but Puppet programs, composed of the Puppet code. File names of Puppet Manifests use the .pp extension.
