PAS-C01 Design of SAP Workloads on AWS Practice Question
A company runs SAP S/4HANA on AWS with a production system in us-east-1 and a disaster recovery (DR) system in us-west-2. The DR system is a standby HANA system using HANA System Replication (HSR) with asynchronous replication. The primary system has a memory of 2 TB and uses x1e.16xlarge instances. The DR system uses identical instance types. Recently, the network latency between the primary and DR sites increased from 50 ms to 150 ms due to a change in the network path. The SAP Basis team notices that the replication lag has increased significantly, and the DR system is now behind by several minutes. The RPO requirement is 30 seconds. The team must resolve the issue without changing the DR site location or the bandwidth. Which action should the team take to meet the RPO?
⚠ Common exam trap
Many candidates assume synchronous replication is the only way to reduce RPO, but they overlook that synchronous mode introduces performance penalties on the primary, and the question's constraint of not changing bandwidth or location forces a protocol-level tuning solution like delta_datashipping.
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
✓
Configure HSR to use delta_datashipping instead of log shipping.
HANA System Replication (HSR) can be configured to use delta_datashipping, which sends only the changed data blocks rather than full redo logs. This reduces the amount of data transferred per replication cycle, making it more resilient to increased network latency. With 150 ms latency, log shipping may fail to meet the 30-second RPO, but delta_datashipping can keep the DR system within the required lag by minimizing per-message payload size.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure HSR to use delta_datashipping instead of log shipping.
Why this is correct
Delta_datashipping reduces data transfer and can meet RPO under higher latency.
- ✗
Increase the AWS Direct Connect bandwidth between the two regions.
Why it's wrong here
The scenario states no change in bandwidth is allowed.
- ✗
Use Amazon S3 cross-region replication for the HANA log backups.
Why it's wrong here
This would not provide near-real-time replication.
- ✗
Change HSR to synchronous replication mode.
Why it's wrong here
Synchronous mode would increase latency impact and may not work with 150ms.
