- A
Take EBS snapshots every 30 minutes and copy them to the DR Region using cross-Region snapshot copy. In the DR Region, have pre-provisioned EC2 instances and EBS volumes ready to attach the restored snapshots
Snapshot copy every 30 minutes meets RPO; pre-provisioning reduces RTO.
- B
Use AWS Backup to schedule daily backups and copy them to the DR Region
Why wrong: Daily backups do not meet the 30-minute RPO.
- C
Set up a pilot light environment in the DR Region with a HANA instance replicating via log shipping
Why wrong: Log shipping over long distances may not keep up and requires manual steps, increasing RTO.
- D
Configure SAP HANA System Replication across Regions using a VPN connection
Why wrong: Cross-Region replication over VPN may have latency and bandwidth issues, and may not meet RTO.
Quick Answer
The correct approach is to take EBS snapshots every 30 minutes and copy them to the DR region using cross-Region snapshot copy, with pre-provisioned EC2 instances and EBS volumes ready in the DR region to restore from those snapshots. This satisfies the 30-minute recovery point objective (RPO) because snapshots are captured at that frequency, while the 4-hour recovery time objective (RTO) is met by having the infrastructure pre-staged and simply attaching the restored volumes. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding of how to balance RPO and RTO using native AWS services for SAP HANA disaster recovery—specifically, that cross-region EBS snapshots provide a cost-effective, asynchronous replication method without requiring HANA system replication. A common trap is assuming you need HANA-specific replication tools, but for a 30-minute RPO, snapshot-based DR is sufficient and simpler to implement. Memory tip: think “Snap30-CopyCross” for the RPO and “PreStage-Restore” for the RTO.
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 multinational company runs SAP on AWS with a complex landscape including development, quality assurance, and production environments. The production SAP HANA database is running on an r5.8xlarge instance with 3.5 TB of data on EBS gp3 volumes. The operations team has been asked to implement a disaster recovery (DR) strategy that can recover the system in another AWS Region within 4 hours. The maximum acceptable data loss is 30 minutes. The current backup strategy uses daily EBS snapshots stored in the same Region. Which approach should the team take to meet the DR 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
Take EBS snapshots every 30 minutes and copy them to the DR Region using cross-Region snapshot copy. In the DR Region, have pre-provisioned EC2 instances and EBS volumes ready to attach the restored snapshots
Cross-Region replication of EBS snapshots and restoring in the DR Region meets the RTO of 4 hours and RPO of 30 minutes if snapshots are taken every 30 minutes. Option B is correct.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
