The company requires a disaster recovery solution for an Aurora PostgreSQL database with a 20-second RPO.
Options:
A.
Reconfigure the database to be an Aurora global database. Set the RPO to 20 seconds.
B.
Reconfigure the database to be an Aurora Serverless v2 database with an Aurora Replica in a separate Availability Zone. Set the replica lag to 20 seconds.
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.
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.
