SAA-C03 Exam - Question 896

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?

Show Answer
Correct Answer: B

To meet a 5-minute RPO and a 20-minute RTO with the most operational efficiency and minimal configuration changes, converting the Aurora cluster to an Aurora global database and configuring managed failover is the best solution. Aurora global database allows for cross-region disaster recovery with seamless replication and minimal performance impact, ensuring a near-instantaneous recovery point objective and a quick recovery time objective. This option leverages AWS's managed services to minimize configuration changes and enhance operational efficiency.

Aurora Global Database: allowing a single Amazon Aurora database to span multiple AWS Regions. It replicates your data with no impact on database performance, enables fast local reads with low latency in each Region, and provides disaster recovery from Region-wide outages.

Answer:B https://aws.amazon.com/rds/aurora/global-database/ Cross-Region disaster recovery If your primary Region suffers a performance degradation or outage, you can promote one of the secondary Regions to take read/write responsibilities. An Aurora cluster can recover in less than 1 minute, even in the event of a complete Regional outage. This provides your application with an effective recovery point objective (RPO) of 1 second and a recovery time objective (RTO) of less than 1 minute, providing a strong foundation for a global business continuity plan.

I go for B. However, C is also a good option except manual failover intervention
