AWS Certified SysOps Administrator – Associate (legacy) — Question 82

An organization is concerned that its Amazon RDS databases are not protected. The solution to address this issue must be low cost, protect against table corruption that could be overlooked for several days, and must offer a 30-day window of protection.
How can these requirements be met?

Answer options

• A. Enable Multi-AZ on the RDS instance to maintain the data in a second Availability Zone.
• B. Create a read replica of the RDS instance to maintain the data in a second region.
• C. Ensure that automated backups are enabled and set the appropriate retention period.
• D. Enable versioning in RDS to recover altered table data when needed.

Correct answer: C

Explanation

The correct answer is C because enabling automated backups with a specified retention period ensures that data is backed up daily and can be restored up to 30 days, meeting the requirement for protection against corruption. Options A and B do not provide a solution for backup and recovery, while option D does not address the need for a comprehensive backup strategy over the specified timeframe.
