- A
Use AWS Backup to take snapshots of the HANA data volume every 5 minutes and copy them to us-west-2.
Why wrong: Snapshot frequency is limited and cross-region copy takes time, exceeding 15 min RPO.
- B
Use Amazon S3 Cross-Region Replication to copy HANA data files to us-west-2.
Why wrong: S3 is not a database replication solution; it lacks transactional consistency.
- C
Set up AWS Database Migration Service (DMS) with ongoing replication from the primary to a secondary HANA database.
Why wrong: DMS is not optimized for HANA replication and may introduce latency.
- D
Configure SAP HANA System Replication (HSR) in active/standby mode between the primary and secondary regions.
HSR provides synchronous or near-synchronous replication with low RPO and fast failover, meeting requirements.
Quick Answer
The answer is SAP HANA System Replication (HSR) in active/standby mode between the primary and secondary regions. This approach meets the SAP HANA cross-region disaster recovery requirements of an RPO under 15 minutes and an RTO under 2 hours because HSR continuously replicates data synchronously or near-synchronously to the standby instance in us-west-2, allowing for automated failover with minimal data loss. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of native SAP replication versus AWS-native services; the common trap is choosing cross-region snapshot copy, which cannot guarantee a sub-15-minute RPO due to snapshot intervals and transfer times. Remember that for real-time SAP HANA replication, you must rely on HANA’s own engine, not generic storage or database migration tools. Memory tip: HSR = HANA’s own replication, not AWS’s.
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 designing a disaster recovery solution for a critical SAP HANA database running on AWS. The primary site is in us-east-1 and the recovery site must be in us-west-2. The database must have a Recovery Point Objective (RPO) of less than 15 minutes and a Recovery Time Objective (RTO) of less than 2 hours. Which approach meets these requirements with the least operational overhead?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"least"Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.
Clue:
"primary"Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.

Correct answer & explanation
Configure SAP HANA System Replication (HSR) in active/standby mode between the primary and secondary regions.
Option A is correct: Using SAP HANA System Replication with HANA's own replication mechanism to a secondary HANA instance in us-west-2 meets RPO <15 min and RTO <2h with minimal overhead, as it is native and automated. Option B is wrong: Cross-Region snapshot copy can take longer than 15 min for RPO. Option C is wrong: DMS is not suitable for real-time HANA replication. Option D is wrong: S3 is for object storage, not direct database replication.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Related concept
Static NAT maps one inside address to one outside address.
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.
