Question 1

A company needs to recover a specific deleted record that is 15 minutes old from an Amazon RDS instance. Which recovery option should they use?

Correct Answer: Perform a point-in-time recovery to a new instance using the latest available automatic backup

To recover a specific record, the best option is to use point-in-time recovery, which allows you to recover the database to a specific point within a custom window. Other options involve full backups or don't apply to recovery scenarios.

Question 2

A company has an RDS instance storing sensitive data, and they require backups to be created every 6 hours. Which solution best achieves this requirement?

Correct Answer: Configure the backup retention period and set the backup window

Amazon RDS creates automated backups by default, but it's required to configure the backup retention period and backup window to specify when the backups should occur. Other wrong answers involve manual snapshots or don't apply to RDS backups.

Question 3

An organization runs Amazon RDS for MySQL in us-east-1. They need an automated disaster recovery strategy that maintains a continuously up-to-date copy of the database in another AWS Region with minimal data loss and quick promotion during a regional outage. Which option best meets these requirements?

Correct Answer: Create a cross-region read replica

Creating a cross-region read replica for Amazon RDS for MySQL provides near real-time, continuous asynchronous replication to another AWS Region. This delivers low RPO and rapid recovery because the replica can be promoted to a standalone instance during a regional outage. Snapshot-based approaches copy data only on a schedule and incur higher RPO; CloudWatch/EventBridge rules alone cannot perform copies and do not provide continuous replication; and relying on AWS global infrastructure does not create a recoverable database in another region.
