AWS Certified Database – Specialty — Question 210

A database specialist needs to move an Amazon RDS DB instance from one AWS account to another AWS account.

Which solution will meet this requirement with the LEAST operational effort?

Answer options

• A. Use AWS Database Migration Service (AWS DMS) to migrate the DB instance from the source AWS account to the destination AWS account.
• B. Create a DB snapshot of the DB instance. Share the snapshot with the destination AWS account. Create a new DB instance by restoring the snapshot in the destination AWS account.
• C. Create a Multi-AZ deployment for the DB instance. Create a read replica for the DB instance in the source AWS account. Use the read replica to replicate the data into the DB instance in the destination AWS account.
• D. Use AWS DataSync to back up the DB instance in the source AWS account. Use AWS Resource Access Manager (AWS RAM) to restore the backup in the destination AWS account.

Correct answer: B

Explanation

The correct answer is B because creating a DB snapshot and sharing it with another account is a straightforward process that requires minimal effort. Option A involves setting up AWS DMS, which is more complex and time-consuming. Option C requires additional infrastructure and configuration for Multi-AZ and read replicas, making it less efficient. Option D involves using AWS DataSync, which is not the most direct method for this scenario.
