DevOps Complete Interview - Practice Questions 2026

Master the DevOps Interview: Complete Practice Exams and Interview Prep

Welcome to the most comprehensive practice exam suite designed to help you ace your DevOps interview. Whether you are a fresh graduate or an experienced engineer looking to transition into a DevOps role, these practice tests are engineered to simulate the pressure and complexity of real-world technical screenings.

Why Serious Learners Choose These Practice Exams

Navigating a DevOps interview requires more than just knowing a few commands; it requires a deep understanding of how development and operations intersect. Serious learners choose this course because it offers a structured, tiered approach to learning. We don't just provide answers; we provide the logic behind the solutions. With detailed feedback on every question, you transform your mistakes into milestones.

Course Structure

The curriculum is divided into six strategic levels to ensure no stone is left unturned:

• Basics / Foundations: We start by solidifying your understanding of the DevOps philosophy. This includes the SDLC, basic Linux commands, and the primary goals of the DevOps movement.

• Core Concepts: Here, we dive into the "Big Three" of DevOps: Version Control (Git), CI/CD pipelines, and basic Cloud infrastructure.

• Intermediate Concepts: This section covers Containerization with Docker, Orchestration basics with Kubernetes, and Infrastructure as Code (IaC) principles.

• Advanced Concepts: Tackle high-level topics like Microservices architecture, Service Mesh, advanced Monitoring/Logging (ELK/Prometheus), and Security (DevSecOps).

• Real-world Scenarios: Practice solving complex "What would you do?" questions that test your ability to troubleshoot production outages and optimize deployment workflows.

• Mixed Revision / Final Test: A comprehensive, timed exam that pulls from all previous levels to test your retention and speed under pressure.

Sample Practice Questions

QUESTION 1

Which of the following best describes the "Blue-Green Deployment" strategy?

• Option 1: Gradually shifting traffic from the old version to the new version in small increments.

• Option 2: Keeping two identical production environments and switching all traffic from one to the other.

• Option 3: Updating a single environment by replacing old instances with new ones one by one.

• Option 4: Testing a new feature on a small subset of users before a full rollout.

• Option 5: Deploying code directly to the production server and restarting the service.

CORRECT ANSWER: Option 2

CORRECT ANSWER EXPLANATION: Blue-Green deployment utilizes two identical environments. The "Blue" environment runs the current version, while "Green" runs the new version. Once testing is complete on Green, traffic is rerouted instantly via a load balancer.

WRONG ANSWERS EXPLANATION:

• Option 1: This is Canary Deployment, not Blue-Green.

• Option 2: Incorrect description of the rolling update method.

• Option 3: This describes a Rolling Update, which involves downtime or reduced capacity during the transition.

• Option 4: This refers to A/B Testing or Canary Testing.

• Option 5: This is a "Big Bang" or direct deployment, which carries high risk and significant downtime.

QUESTION 2

In Kubernetes, what is the primary role of the Kube-proxy component?

• Option 1: Managing the lifecycle of containers within a Pod.

• Option 2: Scheduling Pods onto specific Nodes based on resource availability.

• Option 3: Maintaining network rules on nodes to allow communication to your Pods.

• Option 4: Storing the cluster configuration data and state.

• Option 5: Acting as the primary API gateway for the cluster.

CORRECT ANSWER: Option 3

CORRECT ANSWER EXPLANATION: Kube-proxy is a network proxy that runs on each node in your cluster. It maintains network rules (using IP tables or IPVS) that allow network communication to your Pods from network sessions inside or outside of your cluster.

WRONG ANSWERS EXPLANATION:

• Option 1: This is the responsibility of the Kubelet.

• Option 2: This is handled by the Kube-scheduler.

• Option 3: This is incorrect as Kube-proxy handles networking, not scheduling.

• Option 4: This describes etcd, the distributed key-value store.

• Option 5: This describes the kube-apiserver.

QUESTION 3

Which Git command is used to combine multiple commits into a single, clean commit before merging into the main branch?

• Option 1: git merge --abort

• Option 2: git checkout -b

• Option 3: git rebase -i

• Option 4: git fetch --all

• Option 5: git push --force

CORRECT ANSWER: Option 3

CORRECT ANSWER EXPLANATION: The "git rebase -i" (interactive rebase) command allows users to "squash" multiple commits into one, providing a cleaner project history.

WRONG ANSWERS EXPLANATION:

• Option 1: This simply stops a merge process if a conflict occurs.

• Option 2: This creates and switches to a new branch.

• Option 3: This is the correct tool for commit cleanup.

• Option 4: This downloads objects and refs from another repository but does not modify your commits.

• Option 5: This overwrites remote history and is dangerous if used incorrectly; it does not squash commits.
