- A
Use the 'Azure SQL Database deployment' task with the 'Deploy' action, specifying the DACPAC file and setting the 'Additional Arguments' to include 'p:BlockOnPossibleDataLoss=False' for safety.
This deploys the DACPAC incrementally and allows rollback by redeploying the previous version.
- B
Use the 'Azure SQL Database deployment' task with the 'Query' action to run schema changes.
Why wrong: The 'Query' action is for running ad-hoc queries, not DACPAC deployment.
- C
Use a 'PowerShell' task to run 'SqlPackage.exe' with the DACPAC file.
Why wrong: This works but is not using the built-in task; it requires additional setup.
- D
Use the 'Azure SQL Database deployment' task with the 'Run SQL Script' action, and execute the schema changes as SQL scripts.
Why wrong: SQL scripts are not idempotent and harder to rollback than DACPAC.
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.
Your team uses Azure Pipelines to deploy a multi-tier application to Azure. The application consists of a web frontend, an API backend, and a database. You need to deploy the database schema changes using a DACPAC file. The deployment should be idempotent and support rollback. You must use the Azure SQL Database deployment task. What should you do?
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
Use the 'Azure SQL Database deployment' task with the 'Deploy' action, specifying the DACPAC file and setting the 'Additional Arguments' to include 'p:BlockOnPossibleDataLoss=False' for safety.
Option A is correct: The 'Azure SQL Database deployment' task supports incremental deployment from a DACPAC and allows rollback via additional steps. Option B is incorrect because SQL scripts do not provide the same level of idempotency as DACPAC. Option C is incorrect because executing the DACPAC manually is not automated. Option D is incorrect because the task does support DACPAC deployment.
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 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.
