AZ-400 Design and implement a DevOps infrastructure Practice Question
This AZ-400 practice question tests your understanding of design and implement a devops infrastructure. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 uses Azure DevOps for CI/CD. They have multiple pipelines that deploy to different environments. They want to ensure that secrets like API keys are not exposed in pipeline logs. What is the best approach?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a Variable Group linked to Azure Key Vault
Option C is correct because Variable Groups linked to Azure Key Vault securely store secrets and can be referenced in pipelines without exposing values. Option A is wrong because pipeline variables can be set as secret but still need secure storage. Option B is wrong because Azure App Configuration can store secrets but is less integrated for secret management. Option D is wrong because environment secrets are for Kubernetes, not general pipeline secrets.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use Azure App Configuration with Key Vault references
Why it's wrong here
App Configuration can reference Key Vault, but for pipeline secrets, Variable Groups with Key Vault is the recommended approach.
✓
Create a Variable Group linked to Azure Key Vault
Why this is correct
Variable Groups linked to Key Vault ensure secrets are never stored in the pipeline and are fetched at runtime.
Clue confirmation
The clue word "best" in the question point toward this answer.

Read the scenario before looking for a memorised answer.
✗
Use Azure Kubernetes Service secrets
Why it's wrong here
AKS secrets are for Kubernetes workloads, not for Azure DevOps pipeline secrets.
✗
Use pipeline variables marked as 'secret'
Why it's wrong here
Even though masked, the secret values are still stored in the pipeline definition and can be exposed if someone has access.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
