PAS-C01 Technology Practice Question
A company is running SAP ERP on AWS and wants to implement a disaster recovery (DR) strategy with a Recovery Point Objective (RPO) of 15 minutes and Recovery Time Objective (RTO) of 2 hours. The primary site is in us-east-1, and the DR site is in us-west-2. Which TWO AWS features should be combined to achieve this? (Choose TWO.)
⚠ Common exam trap
Test-takers frequently confuse AWS CloudEndure Disaster Recovery (a third-party tool) with a native AWS feature, or they mistakenly think Amazon RDS Multi-Region replication applies to SAP ERP databases, which are typically self-managed on EC2, not RDS.

Correct answer & explanation
✓
Amazon S3 Cross-Region Replication for database backups
Amazon S3 Cross-Region Replication (CRR) for database backups ensures that backup files are automatically replicated to the DR region within minutes, supporting an RPO of 15 minutes. EC2 AMI Copy allows you to copy pre-configured server images (including OS and SAP application layers) to the DR region, enabling rapid recovery of EC2 instances within the 2-hour RTO. Together, these two features provide a cost-effective, fully automated DR solution for SAP on AWS without requiring third-party tools.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon RDS Multi-Region replication
Why it's wrong here
SAP does not use RDS.
- ✓
Amazon S3 Cross-Region Replication for database backups
Why this is correct
S3 CRR can replicate backups to the DR region with low RPO.
- ✗
AWS CloudEndure Disaster Recovery
Why it's wrong here
CloudEndure is not SAP-certified and may not meet RPO/RTO requirements.
- ✗
Amazon EBS Multi-AZ snapshots
Why it's wrong here
EBS snapshots are not multi-AZ; they are regional but can be copied across regions manually.
- ✓
EC2 AMI Copy to copy server images to the DR region
Why this is correct
AMIs can be copied to the DR region and used to launch instances quickly.
