- A
Increase the frequency of EBS snapshots to every hour and use cross-region copy. Also, pre-warm the DR instance by restoring the latest snapshot.
Why wrong: Hourly snapshots still exceed 15-minute RPO, and restore time may exceed 1 hour RTO.
- B
Use AWS CloudEndure Disaster Recovery to replicate the entire EC2 instance to the DR region.
Why wrong: CloudEndure is a general DR solution but may introduce additional latency and complexity for HANA; also, it may not guarantee database-consistent recovery without application-level integration.
- C
Set up HANA System Replication (HSR) between the primary and DR regions. In the DR region, maintain a standby HANA instance in sync. Use automated failover scripts.
HSR provides low RPO (seconds to minutes) and with a pre-provisioned standby, RTO can be under 1 hour.
- D
Use Amazon EBS multi-region replication for the HANA data volumes.
Why wrong: EBS replication replicates block-level changes but does not ensure database consistency; crash-consistent recovery may not be valid.
Quick Answer
The answer is to set up HANA System Replication (HSR) between the primary and DR regions with a synchronous or synchronous-memory mode standby instance in the DR region, paired with automated failover scripts. This combination directly meets the 15-minute RPO because HSR provides near-continuous, log-based replication that keeps the DR database virtually in sync, far surpassing the daily snapshot approach. For the 1-hour RTO, a pre-provisioned HANA instance eliminates the need to restore from snapshots, and automated scripts handle failover quickly. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding that database-level replication (HSR) is required for low RPO on HANA, while EBS-level tools like snapshot replication or CloudEndure risk inconsistency or performance overhead. A common trap is assuming increased snapshot frequency works, but HSR is the only option that guarantees both low RPO and database consistency. Memory tip: "HSR syncs logs, not blocks—snapshots are for clocks, not clocks ticking every 15 minutes."
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 runs SAP S/4HANA on AWS. The system uses an SAP HANA database with a single EC2 instance. The operations team needs to implement a disaster recovery (DR) strategy with a Recovery Point Objective (RPO) of 15 minutes and a Recovery Time Objective (RTO) of 1 hour. The DR site is in a different AWS Region. The team currently takes daily EBS snapshots and sends them to the DR region using AWS Backup cross-region copy. However, the RPO is not met because snapshots are only taken daily. Which combination of actions should the team take to meet the RPO and RTO?
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 HANA System Replication (HSR) between the primary and DR regions. In the DR region, maintain a standby HANA instance in sync. Use automated failover scripts.
Option B is correct. HANA System Replication provides near-continuous data replication, meeting the 15-minute RPO. For RTO, having a pre-provisioned HANA instance in the DR region and using automated failover procedures can achieve 1-hour RTO. Option A is wrong because increasing snapshot frequency to every hour still does not meet 15-minute RPO and RTO may be longer due to snapshot restore time. Option C is wrong because EBS replication does not guarantee database consistency. Option D is wrong because CloudEndure is designed for server-level replication but may not be optimized for HANA and could impact performance.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the frequency of EBS snapshots to every hour and use cross-region copy. Also, pre-warm the DR instance by restoring the latest snapshot.
Why it's wrong here
Hourly snapshots still exceed 15-minute RPO, and restore time may exceed 1 hour RTO.
- ✗
Use AWS CloudEndure Disaster Recovery to replicate the entire EC2 instance to the DR region.
Why it's wrong here
CloudEndure is a general DR solution but may introduce additional latency and complexity for HANA; also, it may not guarantee database-consistent recovery without application-level integration.
- ✓
Set up HANA System Replication (HSR) between the primary and DR regions. In the DR region, maintain a standby HANA instance in sync. Use automated failover scripts.
Why this is correct
HSR provides low RPO (seconds to minutes) and with a pre-provisioned standby, RTO can be under 1 hour.
Related concept
Static NAT maps one inside address to one outside address.
- ✗
Use Amazon EBS multi-region replication for the HANA data volumes.
Why it's wrong here
EBS replication replicates block-level changes but does not ensure database consistency; crash-consistent recovery may not be valid.
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 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.
