AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A company requires a disaster recovery solution that ensures their database can be quickly restored to the latest state in case of a regional outage. This solution must meet a Recovery Point Objective (RPO) of 5 minutes. Which of the following would best meet these requirements?
Deploying the database in a multi-regional manner with manual data replication
Enabling cross-region read replicas for the Amazon RDS database
Creating automatic backups of the Amazon RDS database every 6 hours
Using Amazon RDS automated snapshots taken every 12 hours
Enabling cross-region read replicas for the Amazon RDS database ensures that the data is replicated in real-time to a secondary region. In the event of a regional outage, the read replica can be promoted to become the new primary database, providing an RPO of close to real-time and minimal data loss. Automatic backups and standard snapshots do not guarantee an RPO of 5 minutes due to their less frequent nature. Multi-regional deployment might provide high availability but does not specify how data is replicated and might not meet the specific RPO requirement.
