DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing

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 double encryption with a customer-managed key in Azure Disk Encryption
Azure Databricks managed disks support double encryption with a customer-managed key (CMK) using Azure Disk Encryption. This provides two layers of encryption: server-side encryption with a platform-managed key and additional encryption with a customer-managed key. Option A (Azure Storage Service Encryption) applies to Azure Storage accounts, not to Azure Databricks managed disks. Option C (TDE) is for Azure SQL Database. Option D (Azure Purview) is a data governance service, not an encryption solution.

Configure Azure Storage Service Encryption with a customer-managed key
Why it's wrong here
SSE is for Azure Blob/Data Lake storage, not managed disks.
- ✓
Enable double encryption with a customer-managed key in Azure Disk Encryption
Why this is correct
Azure Databricks clusters can use Azure Disk Encryption with CMK.
- ✗
Enable Transparent Data Encryption (TDE) in Azure SQL Database
Why it's wrong here
TDE is for SQL databases, not Databricks.
