Full question →mediummultiple choiceObjective-mapped
A company stores sensitive data in Azure Blob Storage. They want to encrypt the data at rest using customer-managed keys (CMK) stored in Azure Key Vault. Additionally, they want the key to be automatically rotated every 90 days without manual intervention. Which configuration should they 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
Distractor review
Enable Azure Storage encryption with a CMK and configure a rotation policy on the storage account.
Storage accounts do not have a key rotation policy; rotation is managed at the Key Vault level.
B
Best answer
Enable Azure Storage encryption with a CMK and enable automatic key rotation in Azure Key Vault by creating a rotation policy.
Key Vault rotation policy handles automatic key version updates. The storage account can be configured to use the key URI without a specific version to pick up new versions automatically.
C
Distractor review
Enable Azure Storage encryption with a CMK and manually rotate the key every 90 days.
Manual rotation is not automatic and requires manual intervention.
D
Distractor review
Use Azure Storage service-side encryption with platform-managed keys and enforce rotation via Azure Policy.
Platform-managed keys cannot be rotated on a schedule; they are managed by Microsoft. The requirement is for CMK.
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: Enable Azure Storage encryption with a CMK and enable automatic key rotation in Azure Key Vault by creating a rotation policy. — To automatically rotate a customer-managed key, you must enable a key rotation policy in Azure Key Vault. The storage account then remains configured to use the same key identifier, but the Key Vault will automatically use the latest version. The storage account itself does not have a key rotation policy.
