PAS-C01 Operations and Maintenance Practice Question
A company runs an SAP system on AWS and wants to implement a disaster recovery (DR) strategy that provides a Recovery Time Objective (RTO) of 2 hours and a Recovery Point Objective (RPO) of 15 minutes. The primary site is in us-east-1 and the DR site is in us-west-2. Which approach meets these requirements?
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
✓
Configure SAP HANA system replication to the DR region and use automatic failover
Configuring SAP HANA system replication to the DR region with automatic failover provides an RTO of less than 2 hours and an RPO of 15 minutes or less. Option A is incorrect because Amazon EBS cross-Region replication does not exist for EBS volumes; snapshots must be copied manually or via AWS Backup, and the RPO would be higher. Option B is incorrect because AWS Backup can copy snapshots, but the minimum backup frequency is hourly (not every 15 minutes), and restoring from snapshots would exceed the RTO. Option D is incorrect because daily backups to S3 have an RPO of 24 hours, which exceeds the required 15 minutes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use Amazon EBS cross-Region replication for all volumes
Why it's wrong here
Replication does not provide automatic failover.
- ✗
Use AWS Backup to copy snapshots to the DR region every 15 minutes
Why it's wrong here
Manual snapshots are not automatic failover; RTO may be higher.
- ✓
Configure SAP HANA system replication to the DR region and use automatic failover
Why this is correct
Provides low RTO and RPO.
- ✗
Take daily backups of the SAP HANA database and store in S3, then restore in us-west-2
Why it's wrong here
RPO is 24 hours, not 15 minutes.
