DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
You are designing a data processing solution in Azure Synapse Analytics. The solution must ensure that data at rest in a dedicated SQL pool is encrypted using customer-managed keys (CMK) stored in Azure Key Vault. The encryption should be enabled at the database level. 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
✓
Transparent Data Encryption (TDE) with a customer-managed key in Azure Key Vault.
Transparent Data Encryption (TDE) with a customer-managed key in Azure Key Vault provides database-level encryption for dedicated SQL pools in Azure Synapse Analytics. TDE encrypts data at rest, and using a customer-managed key (CMK) allows the organization to control the key lifecycle. Option B is incorrect because Azure Purview is for data governance and classification, not encryption. Option C is incorrect because Azure Disk Encryption encrypts VM disks, not the SQL pool database. Option D is incorrect because Always Encrypted is a column-level encryption feature, not for full database encryption.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Transparent Data Encryption (TDE) with a customer-managed key in Azure Key Vault.
Why this is correct
Correct. Transparent Data Encryption (TDE) with a customer-managed key in Azure Key Vault enables database-level encryption for dedicated SQL pools, meeting the requirement.
- ✗
Azure Purview data classification and encryption policies.
Why it's wrong here
Incorrect. Azure Purview is a data governance service used for cataloging and classifying data, not for enabling database-level encryption.
- ✗
Azure Disk Encryption on the nodes hosting the dedicated SQL pool.
Why it's wrong here
Incorrect. Azure Disk Encryption encrypts the managed disks of virtual machines, not the data within a dedicated SQL pool.
- ✗
Always Encrypted with keys stored in Azure Key Vault.
Why it's wrong here
Incorrect. Always Encrypted protects sensitive data at the column level by encrypting column data in transit and at rest, but it does not provide full database-level encryption.
