A company is designing a disaster recovery plan for an Amazon RDS for PostgreSQL database. They require an RPO of 5 minutes and an RTO of 30 minutes in a secondary region. Which TWO actions should be part of the solution? (Select TWO)

Answer options:

Take manual snapshots of the RDS instance every 5 minutes and copy them to the secondary region.

Create a cross-region Read Replica of the RDS instance in the secondary region.

Use AWS Backup to schedule cross-region backups every hour.

Enable Multi-AZ deployment for the RDS instance.

In the event of a disaster, promote the cross-region Read Replica to a standalone database instance.

Use Amazon DynamoDB Global Tables to replicate the PostgreSQL data.

How to approach this question

Identify the RDS feature that provides continuous cross-region replication.

Full Answer

A cross-region Read Replica continuously replicates data asynchronously (meeting 5-min RPO). Promoting it to a primary instance is fast (meeting 30-min RTO).

Common mistakes

Choosing AWS Backup, which cannot achieve a 5-minute RPO.
