Practice a lot of devOps interview questions along with practice excercises to learn devOps and pass interview easily.

Q3. What are the key principles of DevOps?

Ans: The key principle of DevOps includes collaboration, continuous integration and Continuous delivery (CI/CD), automation, monitoring, and feedback loops. These principles help create a smooth and optimised SDLC pipeline where the entire process becomes smooth and safe based on real time feedback from users.

Q4. What is the difference between Agile and DevOps?

Ans: Agile is a methodologies which works based on iterative and incremental approach with high degree of clients collaboration. It is based on tight feedback loops and continuous improvement in product based on those feedback.

DevOps on other hand is a wider approach very similar to agile methodologies but focuses on automating and streamlining the entire software development life cycle with focus on continuous integration and continuous delivery. DevOps ensures that the entire production is faster and reliable while agile is based on speed and flexibility. It is one of the most frequently asked devOps interview questions.

Q5. What is CI/CD in DevOps?

Ans: CI/CD comprises two important processes i,e. Continuous Integration and Continuous Delivery. Continuous integration means frequently merging changes in code into a shared repository and testing them using automation.

Continuous delivery means to ensure that the code is always present in a deployable state. With CI/CD faster software delivery and significant reduction in error is possible.

Q6. What is version control and why is it important in DevOps?

Ans: Version control systems are used to track changes in code and allow multiple developers to collaborate and make changes/overwrite each other’s work.

In DevOps, version control is crucial for managing code, automating CI/CD pipelines, rollbacks, and more. Version control takes the snapshot which can be recalled later when needed.

Q7. What is Infrastructure as Code (IaC)?

Ans: Infrastructure as Code (IaC) is the practice of managing and provisioning infrastructure through code rather than using the manual processes.

Various tools like Terraform or AWS CloudFormation allow you to write infrastructure configurations that can easily be versioned, tested, and deployed like application code. This approach improves consistency, reduces errors, and enables automation in DevOps workflows.

Q8. What are some commonly used DevOps tools?

Ans: DevOps uses a wide range of tools and frameworks to ensure continuous delivery and integration. There are various tools for containerization, delivery, deployment, integration, automation, and more.

Some of the tools are Git for version control, Jenkins/GitHub Actions for CI/CD, Docker for containerization, Kubernetes for container orchestration, Terraform for IaC, Ansible for configuration management, and Prometheus/Grafana for monitoring. Each tool plays a role in automating and improving different parts of the pipeline.

Q9. What is the role of Docker in DevOps?

Ans: Docker is a popular tool in devOps used in containerization that allow applications to run in isolated environments known as containers. Docker is used to develop, ship and run applications using light weight containers. This approach is very helpful for developers to separate their application from business infrastructure giving them more power to deliver better quality.

Q10. What is Kubernetes and how does it relate to DevOps?

Ans: Kubernetes is a portable and extensible open source application used for automating the deployment, scaling and management of the containerized application in DevOps.

It manages containerized workloads and facilitates automation and configuration. It is especially useful in production environments where managing many containers manually becomes impractical.

Q11. What is continuous monitoring in DevOps?

Ans: Continuous monitoring in DevOps is used to track application performance and users experience in real time using tools like Grafana, Prometheus, Nagios, and more which works by collecting logs and metrics.

In DevOps, this helps teams quickly detect issues, reduce downtime, and continuously improve software based on live system behavior and usage patterns. Practice a lot of devOps interview questions along with practice excercises to learn devOps and pass interview easily.

Q12. What are some benefits of using DevOps?

Ans: DevOps provides a range of benefits especially in the software development life cycle including faster software delivery, improved deployment, frequent collaboration, reduced failure rates, and quick recoveries.

It helps reduce the bottleneck of dev and ops team and maintain higher reliability with more quick response to feedback from users.

Q13. How does automation help in DevOps?

Ans: With automation in DevOps cross team collaboration and automation of repetitive tasks become possible. This complete process reduces chances of error, increases reliability, fastens the software delivery process, monitors user experience in real time, and helps in implementing shorter feedback loops. Smart tools like Jenkins, Ansible, and Terraform make automation possible across the entire DevOps lifecycle. Automation is one of the most important DevOps interview questions.

Q14. What is the typical DevOps lifecycle?

Ans: The devOps lifecycle is very simple and follows the effective process starting from planning to monitor phase. Check the stages involved in devOps lifecycle.

Plan
Develop
Build
Test
Release
Deploy
Operate
Monitor

This is a continuous cycle where regular feedback loops are used to improve each stage. DevOps ensures that changes flow smoothly and quickly through each phase, with automation and collaboration driving efficiency.

Q15. Can a non-coder start a career in DevOps?

Ans: A Non-coder can also start a career in devOps especially candidates from non-technical background. If you have strong interest in system administrators, cloud technologies, infrastructure and more in software development then just go for it.

While some scripting or coding knowledge (e.g., Bash or Python) becomes essential over time, many tasks can be learned step-by-step. Starting with Linux, cloud basics, and automation tools is a good entry point.
