Media Management messages for SBT devices are always written to sbtio.log.

RMAN error stacks should be read from the bottom up as that is the order in which errors are generated.

RMAN error stacks should be read from the top down as that is the order in which errors are generated.

The RMAN LOG command line clause causes output issued during RMAN command compilation to be written to a log file and to standard output.

The RMAN LOG command line clause causes output issued during RMAN command compilation to be written to a log file only.

Media Management messages for SBT devices are written to an Oracle trace file.

Q35. A database is configured in archivelog mode.
A full RMAN backup exists but no control file backup to trace has been taken.
A media failure has occurred.
In which two scenarios is incomplete recovery required?

after losing all copies of the control file

after losing all members of an inactive online redo log group

after losing all members of the current online redo log group

after losing an undo tablespace that is in use

after losing a sysaux tablespace data file

Q36. Examine these queries and their output: An online RMAN backup of the CDB was taken an hour before Restore Point R1 was created. You want to recover PDB1 to Restore Point R1. How do you achieve this?

Execute FLASHBACK PLUGGABLE DATABASE PDB1 TO RESTORE POINT R1by using RMAN while connected to PDB1.

Execute FLASHBACK PLUGGABLE DATABASE PDB1 TO RESTORE POINT R1by using SQL while connected to PDB1.

Execute FLASHBACK PLUGGABLE DATABASE PDB1 TO RESTORE POINT R1by using SQL while connected to CDB$ROOT.
