Topic 1 Question 281
A company runs a fleet of web servers using an Amazon RDS for PostgreSQL DB instance. After a routine compliance check, the company sets a standard that requires a recovery point objective (RPO) of less than 1 second for all its production databases.
Which solution meets these requirements?
Enable a Multi-AZ deployment for the DB instance.
Enable auto scaling for the DB instance in one Availability Zone.
Configure the DB instance in one Availability Zone, and create multiple read replicas in a separate Availability Zone.
Configure the DB instance in one Availability Zone, and configure AWS Database Migration Service (AWS DMS) change data capture (CDC) tasks.

Correct Answer is A
👍 7rrharris2023/02/16A: By using Multi-AZ deployment, the company can achieve an RPO of less than 1 second because the standby instance is always in sync with the primary instance, ensuring that data changes are continuously replicated.
