AWS Certified Database – Specialty — Question 126

A financial company recently launched a portfolio management solution. The backend of the application is powered by Amazon Aurora with MySQL compatibility.
The company requires an RTO of 5 minutes and an RPO of 5 minutes. A database specialist must configure an efficient disaster recovery solution with minimal replication lag.
Which approach should the database specialist take to meet these requirements?

Answer options

• A. Configure AWS Database Migration Service (AWS DMS) and create a replica in a different AWS Region.
• B. Configure an Amazon Aurora global database and add a different AWS Region.
• C. Configure a binlog and create a replica in a different AWS Region.
• D. Configure a cross-Region read replica.

Correct answer: B

Explanation

The correct option, B, is ideal because an Amazon Aurora global database allows for low-latency global reads and meets both the RTO and RPO requirements with minimal replication lag. Options A and C involve methods that do not provide the necessary real-time replication or are primarily for migration, while option D only offers a read replica, failing to ensure the required recovery objectives.
