A company plans to enable Azure Disk Encryption (ADE) on a set of Windows virtual machines using a Key Encryption Key (KEK) stored in Azure Key Vault. They have enabled soft-delete and purge protection on the Key Vault. The encryption fails with an error indicating that the key vault does not have the required permissions. Which additional configuration is most likely required for ADE to use the KEK?
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
Best answer
Configure the key vault access policy to grant the Azure Disk Encryption service (or the VM's managed identity) the 'Key Vault Crypto Service Encryption User' role.
Azure Disk Encryption requires permissions to wrap and unwrap the KEK. Granting this role to the appropriate identity ensures ADE can access the key.
B
Distractor review
Enable the key vault for deployment by setting the 'Enabled for deployment' access policy.
This setting is used for Azure Resource Manager template deployments, not for Azure Disk Encryption. It is not the correct fix.
C
Distractor review
Enable the key vault for disk encryption by setting the 'Enabled for Azure Disk Encryption' access policy.
This setting is a legacy option used in older versions of ADE. While it might work, it is not the recommended approach and is not sufficient by itself without also granting the correct permissions. The modern approach uses RBAC roles.
D
Distractor review
Add the 'Storage Account Contributor' role for the VMs to access the key vault.
Storage Account Contributor has nothing to do with accessing Key Vault for disk encryption. The VMs need key permissions, not storage permissions.
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: Configure the key vault access policy to grant the Azure Disk Encryption service (or the VM's managed identity) the 'Key Vault Crypto Service Encryption User' role. — Azure Disk Encryption requires that the Azure platform (specifically the Azure Disk Encryption service) has permissions to read the encryption keys. This is done by granting the 'Key Vault Crypto Service Encryption User' role to the Azure Disk Encryption service principal (for Azure Key Vault RBAC) or by setting access policies. The most common missing step is granting the 'Key Vault Crypto Service Encryption User' role to the appropriate identity (Azure Disk Encryption service or VM's managed identity). Enabling 'Enabled for Azure Disk Encryption' is a legacy setting that may not work with modern deployments.
