Which additional step should the solutions architect take?

A. Migrate the database to an Amazon RDS for MySQL instance with a cross-Region read replica in us-west-2.
B. Migrate the database to an Amazon Aurora global database with the primary in us-east-1 and the secondary in us-west-2.

B. Not the cheapest, but the other ones are either not cross-regional or can't handle the RTO/RPO.

Selected Answer: B

Amazon's documentation states that for Multi-AZ deployments, the typical RTO for failing over to the standby is 60-120 seconds. For read replicas, since the lag is typically larger, the RTO is often cited as around 5-10 minutes under normal conditions.

Selected Answer: A

Why not A? Promoting a read replica will still meet the RTO of 5 minutes while being cheaper than using aurora.
