Full question →hardmultiple choiceObjective-mapped
A company plans to enable Azure Disk Encryption (ADE) on their Windows virtual machines. They will use a Key Encryption Key (KEK) stored in Azure Key Vault. What additional configuration must be made in the Key Vault to allow the Azure platform to access the KEK for encrypting the VM disks?
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
Grant the Azure Disk Encryption service principal 'Reader' role on the key vault.
The 'Reader' role does not provide the necessary cryptographic permissions (Get, WrapKey, UnwrapKey) required by ADE.
B
Best answer
Set the key vault's 'enabledForDiskEncryption' property to true.
This property allows the Azure Disk Encryption service to access the keys and secrets in the vault, which is a standard prerequisite for ADE.
C
Distractor review
Grant the virtual machine's managed identity 'Contributor' role on the key vault.
It's the managed identity of the VM that needs key-level permissions, not the 'Contributor' role, which is too broad and not sufficient for key operations.
D
Distractor review
Configure soft-delete and purge protection on the key vault.
Soft-delete and purge protection are required for using customer-managed keys with ADE, but the question asks for the access configuration needed specifically to allow the platform to access the KEK.
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: Set the key vault's 'enabledForDiskEncryption' property to true. — Azure Disk Encryption requires the key vault to have the 'enabledForDiskEncryption' property set to true. This grants the Azure platform (specifically the Azure Disk Encryption service) the necessary permissions to access the keys/secrets stored in the vault. Granting the ADE service principal specific permissions directly via an access policy is another approach, but the classic method to enable the key vault for disk encryption is setting this property. The 'enabledForDeployment' property is for Azure Resource Manager templates, and 'enabledForTemplateDeployment' is for templates. Soft-delete and purge protection are prerequisites but not the specific access configuration for ADE.
