Full question →hardmultiple choiceObjective-mapped
A company uses Azure SQL Database with Transparent Data Encryption (TDE) and wants to use a customer-managed key (CMK) stored in Azure Key Vault. The security policy requires that the Key Vault be protected by a firewall and virtual network service endpoints to restrict network access. The storage account for TDE logs is in the same Azure region. Which additional configuration is necessary in the Key Vault to allow Azure SQL Database to access the CMK for encryption operations?
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
Add a network rule in the Key Vault firewall allowing the public IP range of the Azure SQL Database server.
Azure SQL Database does not have a fixed public IP range that can be whitelisted. The correct approach is to allow trusted Microsoft services to bypass the firewall, not to add IP rules.
B
Best answer
Enable the 'Allow trusted Microsoft services to bypass this firewall' option in the Key Vault networking settings.
This setting allows trusted Microsoft services like Azure SQL Database to access the Key Vault even when the firewall is enabled, provided the service uses authentication and authorization.
C
Distractor review
Create a private endpoint for the Key Vault and connect it to the same virtual network as the Azure SQL Database.
While a private endpoint is secure, it does not grant access to Azure SQL Database as it runs outside the virtual network. SQL Database is a platform service; it would need a private endpoint as well, or use the trusted services bypass.
D
Distractor review
Configure the Key Vault to use role-based access control (RBAC) and assign the 'Key Vault Crypto Service Encryption User' role to the SQL Database server's managed identity.
RBAC is used for authorization (who can access the key), but the networking firewall still blocks the traffic. The network bypass is required to allow the SQL Database service to reach the Key Vault over the internet.
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 the 'Allow trusted Microsoft services to bypass this firewall' option in the Key Vault networking settings. — When Azure SQL Database uses a CMK in Key Vault for TDE, the SQL service must be able to access the key to encrypt and decrypt the database. If the Key Vault uses firewall rules, you must allow trusted Microsoft services to bypass the firewall. This is done by enabling the 'Allow trusted Microsoft services to bypass this firewall' setting in the Key Vault's networking configuration. Azure SQL Database is a trusted Microsoft service for this purpose.
