Oracle Database 12c: Advanced Administration — Question 17

Which two statements are true about encrypted backups performed by using RMAN?

Answer options

• A. Transparent encryption of backups uses an encryption wallet.
• B. A database uses the same encryption key for every encrypted backup.
• C. A password encryption of backups uses the password while creating and restoring backups.
• D. Image copy backups can be created by using password encryption.
• E. Encrypted backups can only be written to disk.

Correct answer: A, B

Explanation

Option A is correct because transparent encryption indeed requires an encryption wallet for managing keys. Option B is also accurate as a database typically uses a single encryption key for all its encrypted backups. The other options are incorrect; password encryption involves a password but doesn't apply to all backup scenarios, and encrypted backups can be written to other mediums beyond just disk.
