Domain 2.2: Business Continuity — AWS SAP-C02 Practice Question 27

How to approach this question

Recognize that snapshot-based backups usually have RPOs of hours. Continuous replication is needed for minutes/seconds.

Full Answer

C.Use AWS Elastic Disaster Recovery (DRS) to continuously replicate the EC2 instance to a staging area.✓ Correct

Use Amazon EBS Snapshots with Data Lifecycle Manager (DLM) configured for 5-minute intervals.

AWS Elastic Disaster Recovery (DRS) continuously replicates block storage volumes, providing an RPO of seconds, which easily meets the 5-minute requirement. DLM minimum interval is 1 hour.

Common mistakes

Assuming DLM can take snapshots every 5 minutes.

A critical database runs on Amazon EC2 with EBS volumes. The business requires an RPO of 5 minutes. The database does not support native clustering. How can the architect meet this RPO requirement?
