During loading/unloading, staged files encryption uses which of the following?

• A. Only 256-bit AES
• B. Only 128-bit AES
• C. No encryption is used
• D. 128-bit or 256-bit AES encryption

Answer: (D)

Staged file encryption protects data at rest in the stage by using AES-based encryption. For loading and unloading, the system can apply either 128-bit or 256-bit AES keys, depending on the chosen policy or key management setup. That means you have two valid strength options, with 256-bit generally offering stronger security. So the correct understanding is that staged files can be encrypted with either 128-bit or 256-bit AES.

Encryption is required—not using it would expose data in the stage. It isn’t restricted to only one key length, and it isn’t no encryption.
