Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set up SAP HANA System Replication to another AWS region.
To achieve an RPO of 15 minutes and RTO of 2 hours, the company should use SAP HANA System Replication to replicate data to another AWS region (Option A), which provides near-real-time replication meeting the RPO. Additionally, using AWS CloudFormation to automate infrastructure deployment in the DR region (Option C) enables rapid provisioning of the DR environment, meeting the RTO. Option B (Pilot Light with EC2 standby) may not meet the RTO if manual steps are required. Option D (AWS Backup with 15-minute schedules) is not suitable for SAP HANA databases and may not meet RTO. Option E (EBS snapshots every 15 minutes) is not feasible due to performance impact and recovery time.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Set up SAP HANA System Replication to another AWS region.
Why this is correct
HANA System Replication provides near-real-time data replication.
- ✗
Implement a Pilot Light strategy using EC2 instances in standby.

Pilot Light keeps core services running, but failover may exceed RTO.
- ✓
Use AWS CloudFormation to automate infrastructure deployment in the DR region.
Why this is correct
Automation speeds up recovery to meet RTO.
- ✗
Use AWS Backup to schedule backups every 15 minutes.
Why it's wrong here
AWS Backup minimum interval is 1 hour.
- ✗
Take EBS snapshots every 15 minutes.
Why it's wrong here
