Oracle Database 12c: Multitenancy Essentials — Question 22

Which two statements are true about data paths used during RMAN backup and restore operations when media management servers use InfiniBand to connect to an X5 Database Machine?

Answer options

• A. During backups, data blocks are always read from Smart Flash Cache by cellsrv.
• B. During restores, data blocks read from the media are sent to a database server that sends the blocks to cellsrv to be written.
• C. During backups, data blocks are read by cellsrv and sent to a database server, which sends the blocks to the media manager to be written to media.
• D. During backups, data blocks are read by cellsrv and sent directly to the media manager to be written to media.
• E. During restores, data blocks read from the media are sent directly to cellsrv to be written.

Correct answer: D, E

Explanation

Option D is correct because it accurately describes the process of how data blocks are sent directly from cellsrv to the media manager during backups. Option E is also correct as it states that during restores, blocks read from the media are sent directly to cellsrv for writing. The other options incorrectly describe the data flow or processes involved in RMAN operations.
