- A
Create a release with multiple jobs (one per tenant) in the same stage, each deploying to a tenant's staging slot, running tests, and conditionally swapping. Set the 'Run this job' condition to 'Only when all previous jobs have succeeded' or use custom conditions to skip swap on failure.
Multiple jobs can run in parallel, and each job can independently handle success/failure for its tenant.
- B
Create a single stage with a 'foreach' loop over tenants, and if smoke tests fail, skip the swap using a condition.
Why wrong: A loop within a single job is sequential; a failure would stop the loop unless 'continue on error' is used, but then the swap still runs.
- C
Create a single job with parallel tasks for each tenant, and configure failure conditions to skip the swap.
Why wrong: Tasks within a job cannot run in parallel; you need multiple jobs.
- D
Create a single stage with multiple deployment tasks, one per tenant, and use a 'continue on error' option on each task.
Why wrong: 'Continue on error' allows the pipeline to continue but does not skip the swap for the failed tenant; it would still try to swap.
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. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 designing a release pipeline for a multi-tenant SaaS application that is deployed to Azure App Service. Each tenant has its own App Service instance. The pipeline must deploy a new version of the application to a staging slot for each tenant, run smoke tests, and then swap the staging slot to production. You need to ensure that if the smoke tests fail for any tenant, the swap is not performed for that tenant, while other tenants continue. Which release pipeline configuration should you use?
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 release with multiple jobs (one per tenant) in the same stage, each deploying to a tenant's staging slot, running tests, and conditionally swapping. Set the 'Run this job' condition to 'Only when all previous jobs have succeeded' or use custom conditions to skip swap on failure.
Option D is correct because using a multi-job release allows each tenant deployment to be independent, and you can configure pre-deployment conditions or failure conditions to skip the swap for that tenant if tests fail. Option A is wrong because stages are sequential and a failure in one tenant would block others. Option B is wrong because a single job with multiple tasks would still block all tenants if one fails. Option C is wrong because a parallel execution in a single job is not possible; you need multiple jobs.
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.
- ✓
Create a release with multiple jobs (one per tenant) in the same stage, each deploying to a tenant's staging slot, running tests, and conditionally swapping. Set the 'Run this job' condition to 'Only when all previous jobs have succeeded' or use custom conditions to skip swap on failure.
Why this is correct
Multiple jobs can run in parallel, and each job can independently handle success/failure for its tenant.

Why it's wrong here
A loop within a single job is sequential; a failure would stop the loop unless 'continue on error' is used, but then the swap still runs.
- ✗
Create a single job with parallel tasks for each tenant, and configure failure conditions to skip the swap.
Why it's wrong here

Why it's wrong here
'Continue on error' allows the pipeline to continue but does not skip the swap for the failed tenant; it would still try to swap.
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 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.
