DVA-C02 Deployment Practice Question
This DVA-C02 practice question tests your understanding of deployment. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is deploying a containerized application on Amazon EKS. The developer wants to automate the deployment process using a CI/CD pipeline that builds a Docker image, pushes it to Amazon ECR, and updates the Kubernetes deployment. Which tool should the developer use to update the Kubernetes deployment?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
kubectl set image command
The `kubectl set image` command is the standard Kubernetes-native method to update the image of an existing deployment. It directly modifies the deployment's pod template to reference the new Docker image tag, triggering a rolling update. This is the simplest and most direct approach for updating a deployment in a CI/CD pipeline without additional infrastructure.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

AWS Systems Manager Automation
Why it's wrong here
Not designed for Kubernetes updates.
- ✗
AWS CloudFormation with a custom resource
Why it's wrong here

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse the execution environment (like CodeBuild or Jenkins) with the actual tool that performs the update, leading them to select a service like CodeBuild instead of recognizing that `kubectl set image` is the direct and correct tool for the job.
Detailed technical explanation
How to think about this question
Under the hood, `kubectl set image` sends a PATCH request to the Kubernetes API server to update the `spec.template.spec.containers[].image` field of the Deployment resource. This triggers a rollout, where the Deployment controller creates a new ReplicaSet with the updated image and gradually scales down the old ReplicaSet. In a CI/CD pipeline, this command is often combined with `kubectl rollout status` to wait for the update to complete, ensuring the new pods are healthy before proceeding.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
