The answer is Amazon S3 Transfer Acceleration, as it is the AWS service specifically designed to achieve the lowest possible recovery point objective (RPO) for SAP HANA cross-region replication. This service uses optimized network paths and edge locations to accelerate data transfer over long distances, directly reducing the time needed to replicate HANA transaction logs across AWS Regions, which is critical for minimizing data loss in a disaster recovery scenario. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of how to pair specific AWS services with SAP HANA’s replication requirements, often presenting Direct Connect or VPN as traps because they provide private connectivity but lack the built-in acceleration for cross-region throughput. A common memory tip is to think “S3 Transfer Acceleration = speed for long-haul replication,” and remember that while Global Accelerator improves user-facing performance, it does not handle data replication itself.
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. 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 wants to set up an SAP HANA system replication across two AWS Regions for disaster recovery. Which AWS service should they use to achieve the lowest possible recovery point objective (RPO)?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon S3 Transfer Acceleration
Option B is correct because Amazon S3 Transfer Acceleration uses optimized network paths for fast data transfer, reducing RPO for HANA replication. Option A is wrong because AWS Direct Connect is a private connection but does not inherently accelerate data transfer. Option C is wrong because VPN can be slower and less reliable over long distances. Option D is wrong because AWS Global Accelerator improves application performance but not specifically for data replication.
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.
✓
Amazon S3 Transfer Acceleration
Why this is correct
S3 Transfer Acceleration uses AWS edge locations to accelerate uploads, reducing RPO for replication data.
Related concept
Static NAT maps one inside address to one outside address.
✗
AWS Site-to-Site VPN
Why it's wrong here
VPN can introduce higher latency and variability, leading to higher RPO.
✗
AWS Direct Connect
Why it's wrong here
Direct Connect provides consistent network performance but does not optimize data transfer speed for replication.
✗
AWS Global Accelerator
Why it's wrong here
Global Accelerator improves end-user performance but does not directly accelerate data transfer between regions.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PAS-C01 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Amazon S3 Transfer Acceleration — Option B is correct because Amazon S3 Transfer Acceleration uses optimized network paths for fast data transfer, reducing RPO for HANA replication. Option A is wrong because AWS Direct Connect is a private connection but does not inherently accelerate data transfer. Option C is wrong because VPN can be slower and less reliable over long distances. Option D is wrong because AWS Global Accelerator improves application performance but not specifically for data replication.
