- A
Use Azure Pipelines instead of GitHub Actions because it has better integration with AKS. Store secrets in Azure Key Vault and use variable groups.
Why wrong: The question specifies GitHub Actions, so switching to Azure Pipelines is not appropriate.
- B
Create a reusable workflow with OIDC authentication to Azure. Use Helm to deploy, increment chart version, and commit back. Use GitHub environments for approval gates. Integrate container scanning with Docker Scout or Trivy.
This meets all requirements: OIDC for secure auth, Helm for deployment, version bump, approval, and scanning.
- C
Create a workflow per service with direct deployment. Use kubectl commands to deploy. Store all secrets in a single GitHub secret. Skip security scanning to save time.
Why wrong: Using kubectl directly without Helm is not required; skipping scanning violates requirement.
- D
Create a single reusable workflow that each service calls. Use Azure CLI to deploy Helm charts. Store AKS credentials as GitHub secrets. Use a manual approval step via environment protection rules.
Why wrong: Storing AKS credentials as secrets is less secure than OIDC and exposes them if not handled carefully.
AZ-400 Practice Question: Design and implement build and release pipelines
This AZ-400 practice question tests your understanding of design and implement build and release pipelines. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
You are a DevOps engineer for a large e-commerce company. The development team uses GitHub for source control and GitHub Actions for CI/CD. The application is a microservices architecture with 15 services, each in its own repository. You need to implement a continuous delivery pipeline that builds and deploys each service to a Kubernetes cluster in Azure (AKS). The pipeline must meet the following requirements: - Each service must have its own pipeline that triggers on pushes to the main branch. - Deployment to AKS must use Helm charts. - The pipeline must automatically increment the Helm chart version and update the deployment manifest in the repository. - Security scanning must be performed on container images before deployment. - The pipeline must support manual approval for production deployment. - All secrets (e.g., AKS credentials, registry credentials) must be stored securely and not exposed in logs. You need to design the workflow. What is the best course of action?

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
Create a reusable workflow with OIDC authentication to Azure. Use Helm to deploy, increment chart version, and commit back. Use GitHub environments for approval gates. Integrate container scanning with Docker Scout or Trivy.
Using GitHub Actions with OIDC to authenticate to Azure avoids storing long-lived secrets. Helm chart version bumping can be done with a script. The workflow uses environments for approval gates. Container scanning using tools like Trivy can be added as a step.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
