Top 20 DevOps Interview Questions &
Answers in 2023
1. What is DevOps?
DevOps is a set of practices that combine software development (Dev) and IT
operations (Ops) to deliver software services faster, more reliably, and with improved
quality.
2. What are the benefits of DevOps?
DevOps benefits include faster time to market, improved collaboration and
communication between teams, increased efficiency and productivity, and improved
quality and reliability of software services.
3. What are some popular DevOps tools?
Some popular DevOps tools include Jenkins, Git, Docker, Kubernetes, Ansible, Chef,
Puppet, and Nagios.
4. What is continuous integration?
Continuous integration (CI) is a software development practice where developers
frequently integrate code changes into a shared repository, and automated build and
test processes are triggered to detect and fix issues as early as possible.
5. What is continuous delivery?

Continuous delivery (CD) is a software development practice where software changes
are automatically built, tested, and deployed to production environments in a
continuous and efficient manner.
6. What is a container?
A container is a lightweight, portable unit of software that packages an application
and all its dependencies into a single executable package that can run consistently
on any infrastructure.
7. What is Kubernetes?
Kubernetes is an open-source container orchestration system that automates the
deployment, scaling, and management of containerized applications.
8. What is infrastructure as code?
Infrastructure as code (IaC) is a software engineering practice where infrastructure
components such as servers, networks, and storage are defined and managed using
code and automation tools.
9. What is microservices architecture?
Microservices architecture is a software development approach where applications
are built as a collection of small, independent, and loosely-coupled services that can
be deployed and scaled independently.
10. What is monitoring in DevOps?
Monitoring in DevOps is the practice of observing and measuring the performance,
availability, and reliability of software services, and using that data to optimize and
improve the services.
11. What is version control?
Version control is the process of managing changes to files and documents over
time, allowing multiple users to work on the same file and maintain a record of all
changes made.
12. What is agile software development?
Agile software development is an iterative and collaborative approach to software
development that emphasizes flexibility, customer satisfaction, and rapid delivery of
working software.

13. What is a pipeline in DevOps?
A pipeline in DevOps is a sequence of automated tasks and processes that together
build, test, and deploy software services.
14. What is the difference between Git and SVN?
Git is a distributed version control system that allows multiple developers to work on
the same codebase and merge changes independently. SVN is a centralized version
control system that requires a central repository and requires developers to
synchronize their changes with the central repository.
15. What is the difference between Docker and VMs?
Docker is a containerization technology that allows multiple applications to run on
the same host, each in its own isolated container. VMs are virtual machines that run
on a host operating system, with each VM running its own guest operating system.
16. What is the role of DevOps in cloud computing?
DevOps plays a critical role in cloud computing by providing the tools, practices, and
processes needed to deploy and manage applications in the cloud, with a focus on
automation, scalability, and reliability.
17. What are some common challenges faced by DevOps teams?
Common challenges faced by DevOps teams include managing complex
infrastructure, integrating multiple tools and systems, ensuring security and
compliance, and maintaining effective communication and collaboration between
teams.
18. What is a configuration management tool?
A configuration management tool is a software tool that automates the process of
configuring, managing, and monitoring IT infrastructure components, such as
servers, networks, and storage.
19. What is Resilience Testing?
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.
20. Can you differentiate between continuous testing and automation testing?

The difference between continuous testing and automation testing is given below:
Continuous Testing Automation Testing
This is the process of executing all the
automated test cases and is done as part of
the delivery process.
This is a process that replaces manual testing by helping the
developers create test cases that can be run multiple times
without manual intervention.
This process focuses on the business risks
associated with releasing software as early
as possible.
This process helps the developer to know whether the
features they have developed are bug-free or not by having
a set of pass/fail points as a reference.
Career Opportunities in Devops
There are a variety of career opportunities in DevOps, including:
1. DevOps Engineer: responsible for developing, implementing and managing the DevOps
processes and tools to support software development and delivery.
2. Automation Engineer: responsible for developing, testing and maintaining automation
scripts and tools to improve software development and delivery.

3. Cloud Engineer: responsible for managing and deploying cloud infrastructure and services
to support software development and delivery.
4. Site Reliability Engineer (SRE): responsible for ensuring the reliability, availability and
performance of software services by designing and implementing infrastructure and tools.
5. Release Manager: responsible for planning and coordinating software releases, managing
deployment processes, and ensuring software quality and compliance.
6. DevOps Consultant: responsible for advising and assisting organizations in the adoption
and implementation of DevOps practices and tools.
7. Security Engineer: responsible for designing and implementing security measures and
practices to protect software services and infrastructure.
8. Quality Assurance Engineer: responsible for testing software products and services to
