A company uses Azure Managed Disks for their virtual machines. They want to ensure that all managed disks are encrypted at rest using a customer-managed key (CMK) stored in Azure Key Vault. They also want to automatically revoke access to the disks if the key is disabled or deleted. Which feature should they configure?
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 Disk Encryption (ADE) with a Key Encryption Key (KEK)
ADE does encrypt disks but operates inside the VM, requiring additional configuration and agent installation. SSE-CMK is the native disk encryption service for managed disks and provides the same revocation capability without VM overhead.
B
Best answer
Server-side encryption with customer-managed keys (SSE-CMK)
SSE-CMK encrypts managed disks at rest using a CMK. When the key is disabled or deleted, the disk becomes inaccessible, meeting the revocation requirement without additional steps.
C
Distractor review
Azure Storage Service Encryption (SSE) with platform-managed keys
SSE with platform-managed keys encrypts at rest using Microsoft-managed keys. It does not allow customer control or key revocation, so it does not meet the requirement.
D
Distractor review
Azure Key Vault soft-delete and purge protection
Soft-delete and purge protection protect the key from accidental deletion but do not configure encryption on the disks. They are prerequisites for SSE-CMK but not the feature itself.
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: Server-side encryption with customer-managed keys (SSE-CMK) — Server-side encryption with customer-managed keys (SSE-CMK) is the default encryption method for Azure Managed Disks. It uses a CMK from Azure Key Vault to encrypt the disk. If the key is disabled or deleted, the disk becomes inaccessible automatically, providing the desired revocation capability. Azure Disk Encryption (ADE) uses BitLocker/DM-Crypt and also supports CMK but is primarily for OS and data disks inside the VM; SSE-CMK is the recommended and simpler approach for managed disks at rest.
