PAS-C01 Migration Practice Question
An SAP system on AWS is experiencing high latency between the SAP application servers and the HANA database. The application servers are in a different Availability Zone than the database. Which change should a migration specialist recommend to reduce latency without increasing costs significantly?
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
✓
Deploy SAP application servers in the same placement group and Availability Zone as the HANA database
Deploying SAP application servers in the same placement group and Availability Zone as the HANA database minimizes network distance and reduces latency without additional cost. Option A is incorrect: Enhanced Networking improves throughput and reduces packet loss but does not eliminate cross-AZ latency. Option B is incorrect: VPC Peering is used for inter-VPC connectivity, not for reducing latency within the same VPC. Option C is incorrect: using larger instance types does not necessarily reduce network latency and would increase costs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable Enhanced Networking on all instances
Why it's wrong here
Enhanced Networking reduces network jitter and packet loss, not latency across AZs.
- ✗
Create a VPC Peering connection between the application and database subnets
Why it's wrong here
VPC Peering does not reduce latency within the same region.
- ✗
Use larger instance types for the application servers
Why it's wrong here
Instance size does not directly reduce latency across AZs.
- ✓
Deploy SAP application servers in the same placement group and Availability Zone as the HANA database
Why this is correct
Same placement group and AZ minimizes network hops and latency.
