Q30. Which two are true about RMAN encryption?

RMAN can encrypt the Oracle password file.

Dual-mode encrypted backups can be restored only if both the password and the keystore used for encryption are available.

Password encryption can be persistently configured using the CONFIGURE ENCRYPTION command.

RMAN encryption keys are stored in a database wallet.

SET ENCRYPTION command overrides the CONFIGURE ENCRYPTION command settings.

Q36. Which three are true about Transparent Data Encryption (TDE)?

Set encrypt new table spaces parameter to false to stop encrypting the tablespaces.

TDE overrides access controls configured using Oracle Database Vault.

TDE allows you to encrypt sensitive data in individual columns.

TDE stores the master key outside the database in an external security module.

When the TDE master encryption key is reset, backups taken using the old TDE master encryption key become obsolete.

dbcli update_tdekey command is used to update the master encryption key for a PDB.
