Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
CONFIGURE DEVICE TYPE DISK PARALLELISM 4;
Why this is correct
Increasing parallelism allows RMAN to read multiple datafiles simultaneously.
- ✗
CONFIGURE COMPRESSION ALGORITHM 'MEDIUM';
Why it's wrong here
Compression reduces space but increases CPU overhead, potentially slowing backups.
- ✓
ALTER DATABASE ENABLE BLOCK CHANGE TRACKING;
Why this is correct
BCT reduces the time taken for incremental backups by identifying changed blocks.
- ✗
CONFIGURE MAXSETSIZE TO 10G;
Why it's wrong here
This limits set size and does not inherently improve performance.
- ✗
CONFIGURE CONTROLFILE AUTOBACKUP OFF;
Why it's wrong here
Autobackup is critical for recovery and should generally remain on.
