Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A company stores sensitive data in Azure Blob Storage. They want to enforce encryption at rest using a customer-managed key (CMK) stored in Azure Key Vault. Additionally, they require that the key vault be in a different region than the storage account to protect against regional disasters. Can this be achieved, and if so, what is the implication?
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
Yes, but the storage account must use a different key vault per region; no other implications.
This is incorrect because the key vault must be in the same region as the storage account, not just different vaults per region.
B
Distractor review
Yes, but you must enable cross-region replication for the key vault and pay additional costs.
Azure Key Vault offers geo-replication for the vault itself, but this does not enable using a vault from a different region for storage encryption. The storage encryption CMK feature requires the vault to be in the same region.
C
Best answer
No, Azure does not support CMK from a different region than the storage account.
This is correct. The key vault and the storage account must reside in the same region for CMK encryption of Azure Storage.
D
Distractor review
Yes, but you must use a managed identity from the storage account's region to access the key vault.
Managed identity region does not override the requirement; the key vault must be in the same region as the storage account regardless of identity.
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: No, Azure does not support CMK from a different region than the storage account. — Azure Storage encryption with customer-managed keys requires the key vault to be in the same Azure region as the storage account. Cross-region key vaults are not supported for storage encryption. This is a fundamental limitation to be aware of. The storage account cannot use a CMK from a different region, so the requirement cannot be met as stated.
