Free AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A company has deployed a critical database-backed web application in the Northern Virginia region. The operational requirements dictate that the application must be able to recover from a region-wide service disruption and be operational within 4 hours, with data loss not exceeding 15 minutes. What disaster recovery approach would effectively meet these operational objectives?
Create a scaled-down version of the environment in a secondary region, backed up by snapshots on a daily schedule.
Configure multi-regional deployment with data replication to a secondary region and establish a system for automated failover.
Regularly schedule snapshots of the database to a durable storage service with cross-region copying enabled.
Maintain a synchronous standby replica within the same geographical area to ensure instant failover without data loss.
