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. 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.
Which TWO of the following are valid ways to trigger a release pipeline in Azure DevOps? (Select TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Continuous deployment trigger after a build completes.
Option A is correct because Azure DevOps release pipelines can be configured with a continuous deployment trigger that automatically creates a release whenever a build artifact is successfully produced. This is a core feature for enabling automated delivery pipelines, where the release is triggered immediately after the build pipeline completes, ensuring rapid feedback and deployment.
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.
✓
Continuous deployment trigger after a build completes.
Why this is correct
This triggers a release automatically when a build artifact is available.

✗
Source version trigger.
Why it's wrong here
This is not a standard trigger type in release pipelines.
✗
Manual trigger via the 'Create release' button.
Why it's wrong here
Manual creation is not a trigger; it's an action.
✗
Pull request trigger.
Why it's wrong here
PR triggers are for build pipelines, not releases.
✓
Scheduled release trigger.
Why this is correct
Releases can be scheduled at specific times.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse manual release creation (an action) with a configured trigger (an automated event), and they may incorrectly assume that pull request triggers apply to release pipelines when they are only valid for build pipelines.
Detailed technical explanation
How to think about this question
Release pipeline triggers in Azure DevOps are defined in the 'Triggers' tab of a release pipeline, where you can enable continuous deployment after a build, set a scheduled release, or configure a pull request trigger for build pipelines only. The continuous deployment trigger monitors the build artifact and can be filtered by branch or tag, while scheduled triggers use cron expressions (e.g., '0 0 * * *' for daily at midnight) to run releases at specified times. Understanding the distinction between build triggers (CI) and release triggers (CD) is critical for designing efficient pipelines.
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.
