AWS Certified SysOps Administrator – Associate — Question 52

A company runs an encrypted Amazon RDS for Oracle DB instance. The company wants to make regular backups available in another AWS Region.

What is the MOST operationally efficient solution that meets these requirements?

Answer options

• A. Modify the DB instance. Enable cross-Region automated backups.
• B. Create an RDS read replica in another Region. Create a snapshot of the read replica.
• C. Use AWS Database Migration Service (AWS DMS) to copy the data to a DB instance in another Region.
• D. Temporarily turn off encryption on the DB instance. Take a snapshot. Copy the snapshot to another Region.

Correct answer: A

Explanation

The correct answer is A because enabling cross-Region automated backups allows for seamless and efficient backup management without manual intervention. Option B requires additional resources and manual steps to manage the read replica, while C introduces complexity and is not designed specifically for backups. Option D compromises security by disabling encryption, which is not advisable.
