For a data lakehouse that stores highly sensitive information requiring encryption both at rest and in transit, which method ensures high-performance querying on the encrypted data?

Real Exam

Implement column-level encryption, allowing selective decryption for queried columns to reduce computational overhead.

24.7%

Use hardware-accelerated encryption/decryption at the storage level, minimizing the overhead while querying.

42.9%

Encrypt only non-identifiable data fields, leaving key identifiers and commonly queried fields unencrypted for performance.

13.0%

Leverage a proxy layer for on-the-fly encryption and decryption, caching frequently accessed data in its decrypted form.
