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.

Who Should Take This Course
"DevOps Complete Interview - Practice Questions 2026" is aimed at people who want a practical, structured introduction to development without paying full price for it. It's a solid fit if you're starting out in development and want a guided course rather than piecing tutorials together yourself, if you've tried free YouTube content on the topic and want something more organized, or if you already work in a related area and want a refresher you can finish at your own pace. Since enrollment happens on Udemy itself, you keep full access to view the lectures, download any provided resources, and revisit the material later â this isn't a stripped-down or time-limited version of the course.
Why This Course Is Worth Taking
Our take: this listing earns a spot on FreeWebCart because the coupon we verified actually brings the price to $0, not just a token discount, and the course carries a 4.5/5 rating on Udemy. That combination â real reviews plus a working 100% OFF code â is what we look for before publishing a development course. It won't replace hands-on experience or a full degree program, but as a low-risk way to test whether development is worth pursuing further, or to pick up one specific skill, the free price tag makes it an easy yes while the coupon lasts.
