Answers
C.

Modify the database to use a Multi-AZ cluster that has two readable standby instances in separate Availability Zones. Add an Aurora Replica in a separate Availability Zone. Set the replica lag to 20 seconds.

Suggested answer: A

Explanation:

Aurora Global Databases are designed for cross-Region disaster recovery with very low RPO, meeting the 20-second requirement. Setting up Aurora as a global database with the correct configuration ensures low-latency replication and rapid failover, making it ideal for compliance with strict disaster recovery requirements.
