AWS Certified Database – Specialty — Question 81

A database specialist is managing an application in the us-west-1 Region and wants to set up disaster recovery in the us-east-1 Region. The Amazon Aurora
MySQL DB cluster needs an RPO of 1 minute and an RTO of 2 minutes.
Which approach meets these requirements with no negative performance impact?

Answer options

• A. Enable synchronous replication.
• B. Enable asynchronous binlog replication.
• C. Create an Aurora Global Database.
• D. Copy Aurora incremental snapshots to the us-east-1 Region.

Correct answer: C

Explanation

The correct answer is C, as creating an Aurora Global Database allows for low-latency global reads and provides cross-region disaster recovery while maintaining the specified RPO and RTO. Options A and B involve replication methods that could impact performance negatively, and option D does not meet the RPO and RTO requirements in a timely manner.
