DP-300 Configure and manage automation of tasks Practice Question
Exhibit
Invoke-AzSqlDatabaseTransparentDataEncryptionProtector -ServerName "myserver" -ResourceGroupName "myrg" -ProtectorType "AzureKeyVault" -KeyVaultKeyId "https://myvault.vault.azure.net/keys/mykey/abc123"
Refer to the exhibit. You run the above PowerShell command to set the Transparent Data Encryption (TDE) protector for an Azure SQL Database server. What is the result?
⚠ Common exam trap
The trap is confusing server-level and database-level TDE operations — candidates may pick the database-scoped answer because the question mentions a database name, but the cmdlet and the TDE protector are server-scoped objects.

Correct answer & explanation
✓
The server’s TDE protector is changed to a customer-managed key from Azure Key Vault.
The PowerShell command Set-AzSqlServerTransparentDataEncryptionProtector with -Type AzureKeyVault changes the server-level TDE protector to a customer-managed key stored in Azure Key Vault. This is the documented cmdlet for configuring Bring Your Own Key (BYOK) TDE at the Azure SQL logical server level, and the result is that the server's TDE protector is now the specified Key Vault key.
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 command fails because the service principal does not have permissions to the key vault.
Why it's wrong here
The service principal is granted key vault access via the access policy or RBAC role before this cmdlet runs, so permission failure is not the outcome. It is tempting because wrapping a key with a key vault does require authorisation, but the exhibit shows the principal already holds the necessary wrap and unwrap permissions.
- ✗
Transparent Data Encryption is disabled.
Why it's wrong here
Setting a server TDE protector enables or rotates encryption; it never disables TDE, which requires a separate disable operation. It is tempting because protector changes feel destructive, but the cmdlet's purpose is to assign the asymmetric key that encrypts the database encryption key, leaving encryption active.
- ✗
The TDE protector for the database "mydb" is updated.
Why it's wrong here
The cmdlet targets the server-level TDE protector, so it rotates the protector for the logical server, affecting all databases on it, rather than updating a single named database. It is tempting because database-scoped TDE cmdlets exist, but this command's parameter set operates at server scope.
- ✓
The server’s TDE protector is changed to a customer-managed key from Azure Key Vault.
Why this is correct
The cmdlet sets a customer-managed key as the server's TDE protector, satisfying the requirement to move encryption key custody from Microsoft-managed to your own Azure Key Vault. The protector must reside in the same region as the server, and the key's permissions grant the server access for wrap and unwrap operations.
