Full question →mediummultiple choiceObjective-mapped
A company wants to cache frequently accessed session state and product data for their e-commerce website. They need the cache to be highly available with a 99.9% SLA and provide fast read and write access. The solution must be fully managed. Which Azure Cache tier should they choose?
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
Distractor review
Azure Redis Cache Basic tier
Basic tier does not provide high availability (no SLA) and runs on a single node, so it does not meet the requirement for high availability.
B
Best answer
Azure Redis Cache Standard tier
Standard tier offers a 99.9% SLA, replication, and is fully managed, making it suitable for caching with high availability.
C
Distractor review
Azure Redis Cache Premium tier
Premium tier provides additional features like data persistence and clustering, but it is unnecessary for the stated requirement for this requirement and more expensive.
D
Distractor review
Azure Content Delivery Network
Azure CDN is for caching static content (images, videos) at edge locations, not for application session state or dynamic data caching.
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.
