DP-300 Implement a secure environment Practice Question
Which THREE of the following are required to configure Transparent Data Encryption (TDE) with customer-managed keys in Azure Key Vault for Azure SQL Database?
⚠ Common exam trap
Candidates often confuse the requirement for the Key Vault to be in the same region as the database (Option B) with the actual requirement that the Key Vault must have soft-delete and purge protection enabled (Option C), and they may also mistakenly think an RBAC role assignment (Option E) is needed instead of the correct access policy permissions for the server's Azure AD identity.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The key encryption key must be stored in Azure Key Vault.
Transparent Data Encryption (TDE) with customer-managed keys requires the key encryption key (KEK) to be stored in Azure Key Vault. This KEK is used to protect the database encryption key (DEK), which is stored in the database boot record. Without the KEK in Key Vault, the customer-managed key scenario cannot be implemented, as Azure SQL Database must be able to access the key to perform encryption operations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The key encryption key must be stored in Azure Key Vault.
Why this is correct
Customer-managed key is stored in AKV.
- ✗
The Azure Key Vault must be in the same region as the database.
Why it's wrong here
Key Vault can be in any region.
- ✓
The Azure Key Vault must have soft-delete and purge protection enabled.
Why this is correct
Required for TDE with customer-managed keys.
- ✓
The Azure SQL Database server must have an Azure AD identity.
Why this is correct
The server uses its Azure AD identity to authenticate to AKV.
- ✗
The SQL server must have an RBAC role assignment on the key vault.
Why it's wrong here
Access policy is used, not RBAC.
