What should you do?

You have an Azure Synapse Analytics dedicated SQL pool.

You need to ensure that data in the pool is encrypted at rest. The solution must NOT require modifying applications that query the data.

What should you do?
A . Enable encryption at rest for the Azure Data Lake Storage Gen2 account.
B . Enable Transparent Data Encryption (TDE) for the pool.
C . Use a customer-managed key to enable double encryption for the Azure Synapse workspace.
D . Create an Azure key vault in the Azure subscription grant access to the pool.

Answer: B

Explanation:

Transparent Data Encryption (TDE) helps protect against the threat of malicious activity by encrypting and decrypting your data at rest. When you encrypt your database, associated backups and transaction log files are encrypted without requiring any changes to your applications. TDE encrypts the storage of an entire database by using a symmetric key called the database encryption key.
