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.
Your team uses Azure Pipelines for CI/CD. You want to enforce that every build produces a versioned artifact that includes the Git commit ID. Which predefined variable should you use to get the commit ID in a YAML pipeline?
Build.Repository.Name
Why wrong: Incorrect: Build.Repository.Name is the repository name.
Build.BuildId
Why wrong: Incorrect: Build.BuildId is the unique pipeline run ID.
Build.SourceVersion
Correct: Build.SourceVersion contains the commit ID.
Build.SourceBranch
Why wrong: Incorrect: Build.SourceBranch is the branch name.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Build.SourceVersion
Option C is correct because Build.SourceVersion returns the commit ID. Option A is wrong because Build.BuildId is the pipeline build number. Option B is wrong because Build.SourceBranch is the branch name. Option D is wrong because Build.Repository.Name is the repo name.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Build.Repository.Name
Why it's wrong here
Incorrect: Build.Repository.Name is the repository name.
Build.BuildId
Why it's wrong here
Incorrect: Build.BuildId is the unique pipeline run ID.
Build.SourceVersion
Why this is correct
Correct: Build.SourceVersion contains the commit ID.

Build.SourceBranch
Why it's wrong here
Incorrect: Build.SourceBranch is the branch name.
Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
