DBS-C01 Management and Operations Practice Question

A company's Amazon RDS for Oracle instance is running out of storage space. The database administrator wants to add storage without downtime. Which action should be taken?

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 the 'Modify DB Instance' action to increase the allocated storage.

Amazon RDS allows you to modify allocated storage online using the 'Modify DB Instance' action without significant downtime. Option A is wrong because deleting old archived redo logs can free up space temporarily but does not add storage and may impact point-in-time recovery. Option B is wrong because taking a snapshot and restoring to a larger instance requires downtime during the restore process. Option D is wrong because creating a new instance and migrating data involves downtime and is more complex than simply modifying storage.
