When planning database capacity on Amazon RDS, which of the following is a key factor to consider?

The instance class and storage type

A company runs a global application on Amazon Aurora PostgreSQL in the us-east-1 Region. The application has users in North America, Europe, and Asia. The team wants to improve read latency for users in Asia and provide disaster recovery in case of a Regional failure. The recovery point objective (RPO) is 5 minutes, and the recovery time objective (RTO) is 15 minutes. What should a solutions architect do?

Enable Multi-AZ on the Aurora cluster and use the standby for read traffic.

Create a cross-Region read replica in ap-southeast-1 and configure the Asian users to read from the replica. For disaster recovery, promote the replica to a standalone instance.

Use Amazon ElastiCache for Redis in ap-southeast-1 and cache the read data for Asian users.

Create an Aurora Replica in a different Availability Zone in us-east-1 and configure the Asian users to read from it.
