DevOps Interview Questions 2025 | iCert Global

Want to become a DevOps expert? You've come to the right page!

This article will assist you in preparing for DevOps interview interviews. It contains numerous typical questions that interviewers may pose. These questions are based on the experiences of DevOps professionals and more than 30,000 learners worldwide.

DevOps is not software or tools; it's a culture. It brings together the people who develop software and the people who operate it, so they can work as one team. Different organizations practice DevOps differently, but if you learn the right skills, you can fit in anywhere.

We are here to assist you to learn DevOps step by step and become a certified DevOps Engineer. Once you have finished your DevOps course, you will be ready for different jobs in this field.

What do you need to become a DevOps Engineer?

Companies need certain skills while recruiting DevOps Engineers. Some of them are:

• Acquiring knowledge of how to use tools like Chef, Puppet, Ansible, or PowerShell to make computers self-provision.

• Being proficient in coding in programming languages like Ruby, Python, PHP, or Java.

• Possessing the ability to collaborate effectively and communicate effectively across teams.

If you already possess these skills, you can now start preparing to nail interviews. If you don't, don't fret! Our DevOps course will help you learn all of this.

Q1. What is DevOps?

DevOps is a way of developing and deploying software faster and better. It unites two teams—developers (those who develop the software) and IT operations (those who run and maintain the software)—so that they can work together more closely.

With DevOps, teams leverage tools and automation to save time, decrease errors, and rapidly update software. It also focuses on continuous integration (implementing new code in small chunks) and continuous delivery (releasing updates constantly). The objective is to operate as a single team in an attempt to produce and enhance software rapidly and securely.

Q2. Who is a DevOps Engineer?

A DevOps Engineer assists teams in collaborating to create, test, and deploy software faster and more effectively. They have knowledge in software development (coding) and IT operations (the maintenance of systems). Their role is to ensure everything runs smoothly.

Some of the activities that a DevOps Engineer performs :

1. Teamwork – Allows developers and operations teams to collaborate.

2. Automation – Creates tools that do jobs by themselves (like testing and starting software).

3. CI/CD - Facilitates more frequent and secure updating of software.

4. Infrastructure as Code – Utilizes code to control and construct systems.

5. Monitoring – Watches systems to catch problems early.

6. Security – Develops software in a secure manner.

7. Cloud Platforms – Leverages cloud tools like AWS or Azure to enable applications to perform optimally.

8. Troubleshooting – Fixes problems when something goes wrong.

9. Learning – Keeps learning new tools and tricks to improve.

A DevOps Engineer assists the entire business to run more effectively by accelerating software development and enhancing its quality.

If you wish to be a DevOps Engineer, you can be a member of the DevOps Course Master's Program by iCert Global. It builds useful skills and tools with hands-on experience and knowledge to aid career advancement.

Q3. Why do we require DevOps?

Today, businesses prefer to provide minimum updates to their software from time to time rather than waiting and making huge updates all at once. It benefits them:

• Request users for rapid feedback.

• Make software better

• Keep customers satisfied

For this to be achieved, firms should:

• Publish updates frequently

• Prevent errors in rolling out new features

• Solve problems quickly

• Fix things quickly if they break.

DevOps makes all of this possible. It makes teamwork easier, automates tasks, and speeds up the delivery of quality software.

Big companies such as Google, Amazon, and Etsy use DevOps. They can deploy updates every few days without compromising anything about stability or security.

Q4. What makes DevOps different from Agile?

Agile is a way of developing software in small parts. Agile assists teams in breaking down big ideas and making them into functional programs. Agile is best for breaking down software planning, development, and testing into small pieces so that it can be changed easily.

But that is not enough. Not only do you have to create the software, you have to deploy that software into the real world — i.e., deploy it onto people's phones or websites. That is where DevOps comes in.

DevOps allows you to easily deploy and run software. DevOps uses tools to deploy software from your developer machine to the external world securely and quickly.

Basic Difference:

• Agile   — Seeks to deliver the software

• DevOps  —  Aims to build and deploy software securely to users.

Both are crucial — they assist in various ways with creating software!

Q5. What are the greatest DevOps tools? What tools have you used?

Some of the most widely used DevOps tools are listed below:

• Git – helps you track changes to the code.

• Jenkins – builds and tests code automatically.

• Selenium – guarantees that the software functions as it should.

• Puppet, Chef, and Ansible – help set up and control systems automatically.

• Nagios – it checks the system to ensure everything is fine

• Docker – packages software into tiny packages so it behaves the same everywhere

If you have utilized all these devices, you can assert:

I have used all these tools to develop, test, and deploy software rapidly and securely.

If you've tried a few, say:

I know how to use [name the tools you know], and I understand the basics of the others.

Q6. How Do All These DevOps Tools Work Together?

Here's how the tools help make and initiate software step by step:

1. Git helps developers save and share their code.

2. The code enters a common Git folder (termed a repository).

3. Jenkins looks for new code, compiles it, and tests it.

4. Puppet or Ansible tools assist in setting up the test environment.

5. Selenium performs tests to ensure code functionality.

6. If everything is good, Jenkins sends the code to be used by real people.

7. Monitoring tools such as Nagios monitor everything to detect issues ahead of time.

8. Docker provides the developers with the same environment to test that they will eventually use, and thus fewer surprises.

Q7. What is the DevOps Pipeline?

A DevOps pipeline is a procedure that helps teams build, test, and deliver software rapidly by utilizing automation. It is also called the CI/CD pipeline, or Continuous Integration and Continuous Delivery. This pipeline helps in transferring code from the developer's computer to the users quickly and safely.

These are the general steps in the process:

1. Code Change: Coders write code and store it in a unique storage location such as Git.

2. Build: An automated tool inspects and constructs the new code to get it working.

3. Create Files: If all works out, it creates files which can be used or shared.

4. Test Environment: These files are tested in a test environment that's similar to the real one.

5. Automated Tests: The program executes automated tests to detect errors or bugs.

6. Go Live: After passing all tests, the software is released to actual users.

7. Monitor: Once live, tools watch over it to make sure everything runs smoothly.

Q8. What are the benefits of DevOps?

DevOps has numerous excellent advantages:

Technical benefits:

Software is updated more frequently.

• It is simpler to correct issues.

• Problems are resolved quicker.

Business advantages:

• New features are experienced by the users earlier.

• The systems work more efficiently and don't break down often.

• Teams can spend more time on improvement than bug fixing.

Q9. What are some major benefits of DevOps?

• Applications are developed and sent quicker.

• DevOps is easy to adjust when things change.

• There is less confusion because the software works better.

• Developers and ops teams talk to each other more.

• Automation does things better and quicker.

• Customers are happier with better and faster updates.
