DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
Which TWO actions should you take to ensure that data at rest is encrypted in Azure Synapse Analytics dedicated SQL pool?
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
✓
Enable infrastructure-level encryption using double encryption.
The correct actions are B and E. Transparent Data Encryption (TDE) with service-managed keys (Option E) encrypts the entire dedicated SQL pool at rest by default. Infrastructure-level encryption using double encryption (Option B) adds a second layer of encryption at the infrastructure level, providing extra protection. Option A (Always Encrypted with secure enclaves) is for client-side encryption during queries, not at rest. Option C (column-level encryption with ENCRYPTBYPASSPHRASE) encrypts specific columns, not the entire pool. Option D (creating a customer-managed key in Azure Key Vault) is a prerequisite for TDE with customer-managed keys, but the action to enable encryption itself is TDE; Option E with service-managed keys already achieves at-rest encryption without requiring a customer-managed 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.
- ✗
Enable Always Encrypted with secure enclaves.
Why it's wrong here
Always Encrypted protects data in use and in transit, not at rest.
- ✓
Enable infrastructure-level encryption using double encryption.
Why this is correct
Azure Storage double encryption provides additional layer at rest.
- ✗
Apply column-level encryption using ENCRYPTBYPASSPHRASE.
Why it's wrong here
This is application-level, not a built-in at-rest encryption for the pool.
- ✗
Create a customer-managed key in Azure Key Vault.
Why it's wrong here
This is a prerequisite for TDE with CMK, but encryption is not enabled until TDE is turned on.
- ✓
Enable Transparent Data Encryption (TDE) using service-managed keys.
Why this is correct
TDE encrypts the entire database at rest.
