You manage an API in Azure API Management. You need to cache API responses such that different responses are returned based on the product subscription key used by the caller. Which set of policies should you implement?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Set a 'cache-lookup' policy in the inbound section and a 'cache-store' policy in the outbound section, using the subscription key as a cache vary-by parameter.
This is the correct pattern: lookup cache on request, store on response, varying by subscription key.
B
Distractor review
Set a 'cache-store' policy in the inbound section and a 'cache-lookup' policy in the outbound section.
This reverses the roles: storing on inbound before the backend is called is incorrect; caching must happen after the backend response.
C
Distractor review
Set both 'cache-lookup' and 'cache-store' policies in the inbound section.
Both in inbound would attempt to store before the backend response, and the stored response would be empty or wrong.
D
Distractor review
Set only a 'cache-store' policy in the backend section.
The backend section does not support caching policies; caching is done in inbound/outbound of the API.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this AZ-204 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Set a 'cache-lookup' policy in the inbound section and a 'cache-store' policy in the outbound section, using the subscription key as a cache vary-by parameter. — To cache responses per subscription (product), you use inbound 'cache-lookup' policy to check the cache with a vary-by-subscription-id key, and outbound 'cache-store' policy to store the response. The inbound section is for looking up the cache; the outbound section is for storing the response after backend processing. Setting both in inbound or only outbound would not work correctly.
