When two statements are true?

A Data Guard environment has this configuration and these attributes:
1. A primary database
2. A Physical Standby Database named sbdb
3. The configuration is in maximum availability protection mode.
Then sbdb is converted to a snapshot standby database.
When two statements are true?

A.
Sdbd can still apply redo.

B.
The recovery point objective increases.

C.
The protection mode is lowered to maximum performance.

D.
The recovery time objective increases.

E.
Sbdb can still receive redo

Explanation:
E: A snapshot standby database receives and archives, but does not apply, redo data from a primary database.
D: Snapshot standby databases are best used in scenarios where the benefit of having a temporary, updatable snapshot of the primary database justifies additional
administrative complexity and increased time to recover from primary database failures.
Note: Redo data received from the primary database is applied when a snapshot standby database is converted back into a physical standby database, after
discarding all local updates to the snapshot standby database.
The data in the primary database is fully protected however, because a snapshot standby can be converted back into a physical standby database at any time, and
the redo data received from the primary will then be applied.
Incorrect Answers:
A: A snapshot standby database receives and archives, but does not apply, redo data from a primary database.
