  1. DevOps INTERVIEW QUESTIONS 1) What are the advantages of DevOps? 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)

  2. 2) List the essential DevOps tools. • Git • Jenkins • Selenium • Puppet • Chef • Ansible • Nagios • Docker • Monit • ELK –Elasticsearch, Logstash, Kibana • Collectd/Collect • Git(GitHub)

  3. 3) The scope for SSH • SSH is a Secure Shell which provides users with a secure, encrypted mechanism to log into systems and transfer files. • To log out a remote machine and work on command line. • To secure encrypted communications between two hosts over an insecure network. 4) List the major difference between the Agile and DevOps. Agile: • Agile is about software development Devops: • DevOps is about software deployment and management. • DevOps does not replace Agile or Lean. It does this by killing waste, removing handovers, and streamlining deployments to allow faster and more continuous deployments to PRODUCTION.

  4. 5)Name the popular scripting language of DevOps • Python 6) What is docker swarm? • Group of Virtual machines with Docker Engine can be clustered and maintained as a single system and the resources also being shared by the containers and docker swarm master schedules the docker container in any of the machines under the cluster according to resource availability • Docker swarm init can be used to initiate docker swarm cluster and docker swarm join with the master IP from client joins the node into the swarm cluster.

  5. 7) What are the uses of integrating cloud with DevOps? The centralized nature of cloud computing provides DevOps automation with a standard and centralized platform for testing, deployment, and production.Most cloud providers gives Even Devops technologies like CI tools and deployment tools as a service like codebuild, codepipeline, codedeploy in AWS makes easy and even faster rate of Devopspratice. 8) How to Version control Docker images? Docker images can be version controlled using Tags , where you can assign tag to any image using docker tag <image-id> command. And if you are pushing any docker hub registry without tagging the default tag would be assigned which is latest , even if a image with the latest is present , it demotes that image without tag and reassign that to the latest push image. 9) Explain how DevOps is helpful to developers? DevOps can be helpful to developers to fix the bug and implement new features quickly. It also helps for clearer communication between the team members.

  6. 10) Mention what are the types of Http requests? • The types of Http requests are • GET • HEAD • PUT • POST • PATCH • DELETE • TRACE • CONNECT • OPTIONS 11) How is Chef used as a CM tool? • Chef is considered to be one of the preferred industry-wide CM tools. Facebook migrated its infrastructure and backend IT to the Chef platform, for example. Explain how Chef helps you to avoid delays by automating processes. The scripts are written in Ruby. It can integrate with cloud-based platforms and configure new systems.

  7. 12)What is the role of AWS in DevOps? When asked this question in an interview, get straight to the point by explaining that AWS is a cloud-based service provided by Amazon that ensures scalability through unlimited computing power and storage. AWS empowers IT enterprises to develop and deliver sophisticated products and deploy applications on the cloud. Some of its key services include Amazon CloudFront, Amazon SimpleDB, Amazon Relational Database Service, and Amazon Elastic Computer Cloud. Discuss the various cloud platforms and emphasize any big data projects that you have handled in the past using cloud infrastructure. 13) What is Jenkins? Jenkins is an open source automation tool written in Java with plugins built for Continuous Integration purpose. Jenkins is used to build and test your software projects continuously making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build. It also allows you to continuously deliver your software by integrating with a large number of testing and deployment technologies.

  8. 14) Mention some of the useful plugins in Jenkins? • Below I have mentioned some important Plugins: • Maven 2 project • Git • Amazon EC2 • HTML publisher • Copy artifact • Join • Green Balls 15) What are the various ways in which build can be scheduled in Jenkins? • You can schedule a build in Jenkins in the following ways: • By source code management commits • After completion of other builds • Can be scheduled to run at specified time ( crons ) • Manual Build Requests
