Domain 2.2: Business Continuity — AWS SAP-C02 Practice Question 38

How to approach this question

Select backup/replication strategies that match the RPO/RTO without overspending.

Full Answer

Configure Amazon RDS cross-region automated backups., Use AWS Backup to schedule hourly cross-region snapshots of the EC2 instances., Configure S3 Cross-Region Replication (CRR) for the S3 buckets.

For a 1-hour RPO and 4-hour RTO, snapshot-based backups and asynchronous replication are sufficient and cost-effective. Active-active or continuous replication (DRS) would be over-provisioning and too expensive.

Common mistakes

Choosing DRS or Active-Active, which are for near-zero RPO/RTO and cost significantly more.
