A company is using Amazon RDS for Oracle with Automated Backups enabled. The database size is 1 TB. The company wants to improve the backup and restore performance. Which TWO actions should be taken? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Provisioned IOPS storage for the database.
Using Provisioned IOPS storage improves I/O performance, which speeds up backup and restore operations. Option B is correct because enabling backup compression reduces the backup size, leading to faster transfer and restore times. Option C is wrong because using a smaller DB instance class would degrade performance, not improve it. Option D is wrong because increasing the backup retention period to 35 days does not affect backup performance; it only increases the storage used. Option E is wrong because disabling Multi-AZ would reduce availability and does not improve backup performance; in fact, Multi-AZ can improve backup performance by offloading backups to the standby instance.

Why this is correct
Compression reduces the amount of data written and transferred.
- ✗
Use a smaller DB instance class to reduce backup size.
Why it's wrong here
Smaller instance class would have lower performance.
- ✗
Increase the backup retention period to 35 days.
Why it's wrong here
Retention period does not affect backup speed.
- ✗
Disable Multi-AZ to reduce backup time.
Why it's wrong here
Disabling Multi-AZ reduces availability and may not improve backup performance.
