The correct choice is to schedule hourly EBS snapshots and copy them to the DR region using AWS Backup. This solution directly meets the required Recovery Point Objective of 1 hour by automating snapshot creation every hour, while the cross-region copy ensures the backup data resides in a different AWS Region for disaster recovery. For the Recovery Time Objective of 2 hours, you restore the SAP EC2 instance from those copied snapshots in the DR region, which is feasible with proper automation. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of native AWS backup services versus third-party or S3-based replication—common traps include confusing S3 Cross-Region Replication (which works for objects, not EBS snapshots) or over-engineering with CloudEndure continuous replication. Remember the memory tip: “Snapshots for SAP, S3 for objects”—AWS Backup is the native, cost-effective way to achieve cross-region DR with hourly RPO for EBS-backed SAP systems.
PAS-C01 Operations and Maintenance Practice Question
This PAS-C01 practice question tests your understanding of operations and maintenance. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is running SAP ERP on AWS using an SAP-certified AMI. The system uses a single EC2 instance for both the application and database. The operations team needs to implement a disaster recovery (DR) solution with a Recovery Time Objective (RTO) of 2 hours and a Recovery Point Objective (RPO) of 1 hour. The DR site must be in a different AWS Region. Currently, the system uses EBS snapshots for backup. What should the team do to meet the RTO and RPO requirements?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Schedule hourly EBS snapshots and copy them to the DR region using AWS Backup.
Option D is correct because using AWS Backup with cross-region snapshot copy allows automated backups to another region with RPO of 1 hour. For RTO, you can restore from those snapshots. Option A is wrong because S3 replication is for objects, not EBS snapshots. Option B is wrong because Cross-Region Replication is for S3. Option C is wrong because CloudEndure requires continuous replication, which is not needed and may be overkill.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 a read replica in the DR region and promote it during failover.
Why it's wrong here
Read replicas are for RDS, not for EC2-based databases.
✗
Configure Amazon S3 Cross-Region Replication for the EBS snapshots.
Why it's wrong here
EBS snapshots are not stored in S3 directly; they are stored in Amazon EBS snapshot service.
✗
Use AWS CloudEndure Disaster Recovery to replicate the entire server to the DR region.
Why it's wrong here
CloudEndure can meet RPO of seconds, but it's more complex and costly for the given RPO of 1 hour.
✓
Schedule hourly EBS snapshots and copy them to the DR region using AWS Backup.
Why this is correct
This meets RPO of 1 hour and RTO of 2 hours by restoring from snapshots.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
