A company uses Azure Blob Storage to store archival data that is rarely accessed. The security policy requires that the data must be encrypted at rest using a unique Microsoft-managed key per storage account, and the data must be stored cost-effectively while allowing retrieval within 15 minutes. Which storage account type and encryption configuration 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.
Distractor review
BlockBlobStorage account with infrastructure encryption
BlockBlobStorage is optimized for high transaction scenarios, not archival, and infrastructure encryption (double encryption) adds cost without being required.
Distractor review
BlobStorage account with Hot access tier and default encryption
The Hot tier has higher storage costs and is not cost-effective for archival data.
Best answer
General-purpose v2 account with Cool access tier and default encryption
GPv2 accounts support Cool tier (low cost, retrieval within minutes) and default SSE with unique Microsoft-managed keys.
Distractor review
General-purpose v1 account with Archive access tier and default encryption
Archive tier has retrieval times that can exceed 15 minutes (usually hours), and GPv1 accounts do not support all modern features.
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-500 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: General-purpose v2 account with Cool access tier and default encryption — A General-purpose v2 (GPv2) storage account with the Cool access tier meets the cost and retrieval time requirements. Default encryption uses server-side encryption (SSE) with Microsoft-managed keys, which are unique per storage account. The BlobStorage account with Hot tier is more expensive. Archive tier has retrieval times of hours, not minutes. Infrastructure encryption provides double encryption but is not required. BlockBlobStorage accounts are recommended for high transaction workloads, not archival.
