DP-300 Implement a secure environment Practice Question
You have an Azure SQL Database with Always Encrypted enabled for sensitive columns. You need to grant a developer the ability to encrypt data using a column master key stored in Azure Key Vault. What permissions must be assigned to the developer's Microsoft Entra identity in the key vault?
⚠ Common exam trap
The trap is that candidates often assume only Wrap Key is needed for encryption, but in Always Encrypted, the client driver must also unwrap the existing column encryption key from its encrypted form to use it for encrypting data. Both Unwrap Key and Wrap Key are required operations during encryption tasks.
Answer choices
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
✓
Get, Wrap Key, and Unwrap Key.
To encrypt data with Always Encrypted, the client driver must retrieve the column encryption key (which is stored encrypted) and unwrap it using the column master key. It may also need to wrap newly generated column encryption keys during key rotation or initial setup. Therefore, the developer's Microsoft Entra identity requires Get, Unwrap Key, and Wrap Key permissions on the column master key in Azure Key Vault. Option B correctly includes all three.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Get, Decrypt, and Unwrap Key.
Why it's wrong here
Decrypt is not needed for encryption; wrap is needed.
- ✓
Get, Wrap Key, and Unwrap Key.
Why this is correct
Wrap Key is needed to encrypt, and Unwrap Key is needed to decrypt. Get is required to retrieve the key metadata.
- ✗
Get and Decrypt.
Why it's wrong here
Decrypt alone is insufficient; wrap/unwrap are required.
- ✗
Get, Sign, and Verify.
Why it's wrong here
Sign and Verify are not used for Always Encrypted key operations.
