Question 14 of 100 | ← Chapter 13

Q914. A company is designing its production application's disaster recovery (DR) strategy. The application is backed by a MySQL database on an Amazon Aurora cluster in the us-east-1 Region. The company has chosen the us-west-1 Region as its DR Region.The company's target recovery point objective (RPO) is 5 minutes and the target recovery time objective (RTO) is 20 minutes. The company wants to minimize configuration changes.Which solution will meet these requirements with the MOST operational efficiency?

Correct Answer: B. Convert the Aurora cluster to an Aurora global database. Configure managed failover.

Explanation

To meet the company's requirements of a 5-minute Recovery Point Objective (RPO), a 20-minute Recovery Time Objective (RTO), and minimizing configuration changes, the most operationally efficient solution is:B. Convert the Aurora cluster to an Aurora global database. Configure managed failover.Aurora Global Database is specifically designed for disaster recovery scenarios. It provides low-latency global replication across multiple regions. By converting the Aurora cluster to an Aurora Global Database, the company can achieve near real-time replication of the database to the us-west-1 Region.Configuring managed failover ensures that in the event of a primary region failure, failover to the DR region is automatically triggered. This minimizes the recovery time and reduces the need for manual intervention.Option A suggests creating an Aurora read replica in us-west-1. While this provides a replica of the database, it does not meet the target RPO and RTO requirements specified by the company.Option C suggests creating a new Aurora cluster in us-west-1 with Cross-Region Replication. Although it provides replication across regions, it requires additional configuration and management overhead compared to Aurora Global Database with managed failover.Option D suggests creating a new Aurora cluster in us-west-1 and using AWS Database Migration Service (AWS DMS) to sync both clusters. While this solution can achieve replication, it adds complexity and operational overhead compared to using Aurora Global Database.In summary, option B, converting the Aurora cluster to an Aurora Global Database and configuring managed failover, provides the most operationally efficient solution for meeting the company's requirements of RPO, RTO, and minimizing configuration changes for their production application's disaster recovery strategy.
