PAS-C01 Migration Practice Question
A company is migrating an SAP HANA database using SAP HANA System Replication (HSR) to AWS. The target EC2 instance is in a different AWS Region than the source. The network latency between regions is high. What should the migration team configure to ensure successful replication?
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
✓
Use AWS Global Accelerator to route traffic over the AWS global network
A VPN connection adds overhead and latency over the internet, worsening replication issues. Option B is incorrect because disabling HSR preload reduces memory usage but does not address high latency; it may even increase recovery time. Option C is correct because AWS Global Accelerator uses the AWS global network to optimize routing, reducing latency impact for HSR replication. Option D is incorrect because increasing HSR timeout values only masks timeout symptoms without resolving the underlying latency problem.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set up a VPN connection to the target region
Why it's wrong here
VPN adds overhead and does not optimize path.
- ✗
Disable HSR preload on the target
Why it's wrong here
Disabling preload reduces resource use but not latency.
- ✓
Use AWS Global Accelerator to route traffic over the AWS global network
Why this is correct
Global Accelerator uses optimized paths to reduce latency and jitter.
- ✗
Increase the HSR timeout values significantly
Why it's wrong here
Timeout increase only prevents disconnects, does not improve replication speed.
