DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
Your organization uses Azure Synapse Analytics dedicated SQL pool. You need to ensure that all data at rest in the SQL pool is encrypted using a customer-managed key stored in Azure Key Vault. What should you configure?
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 Transparent Data Encryption (TDE) with a customer-managed key in Azure Key Vault.
Transparent Data Encryption (TDE) with customer-managed keys in Azure Key Vault provides the required encryption for data at rest in Azure Synapse Analytics dedicated SQL pool. Option A is wrong because Always Encrypted protects data in transit and at rest in application logic, not at rest in the database. Option B is wrong because Dynamic Data Masking does not encrypt data; it obfuscates it for users. Option C is wrong because Azure Storage Service Encryption is for Azure Storage accounts, not for SQL pools.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Implement Always Encrypted with column encryption keys stored in Azure Key Vault.
Why it's wrong here
Always Encrypted encrypts data at the column level and is managed by client drivers, not a server-level encryption for the entire pool.
- ✗
Configure Dynamic Data Masking to obfuscate sensitive data.
Why it's wrong here
Dynamic Data Masking hides data from non-privileged users but does not encrypt it.
- ✗
Enable Azure Storage Service Encryption with a customer-managed key.
Why it's wrong here
Azure Storage Service Encryption is used for Azure Storage, not for Azure Synapse dedicated SQL pool.
- ✓
Enable Transparent Data Encryption (TDE) with a customer-managed key in Azure Key Vault.
Why this is correct
TDE with customer-managed key provides encryption at rest for the entire database, meeting the requirement.

Key term
Azure Data Masking
Azure Data Masking is a security feature that hides sensitive data in database query results by replacing it with obscured characters, so unauthorized users see a blurred version instead of the real information.
Key term
Dynamic Data Masking
Dynamic Data Masking is a security feature that automatically hides sensitive data in query results so that unauthorized users see only masked information, while authorized users see the real data.
