PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is migrating SAP ECC to AWS and needs to ensure low-latency connectivity between the SAP application and database servers. Which AWS service is most appropriate to achieve this?
⚠ Common exam trap
It's easy for candidates to confuse network connectivity services (VPC peering, Transit Gateway, Direct Connect) with compute-level placement strategies, assuming any 'connection' service can reduce latency, when only placement groups provide the physical proximity required for low-latency inter-instance communication.
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
✓
Placement groups for the application and database instances.
Placement groups, specifically cluster placement groups, provide low-latency, high-throughput network connectivity by placing instances in a single Availability Zone within a low-latency, 10 Gbps network. This is ideal for SAP ECC where the application and database servers require consistent, sub-millisecond latency for optimal performance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
VPC peering between the application and database subnets.
Why it's wrong here
Wrong; VPC peering is for different VPCs, not for low latency within same VPC.
- ✓
Placement groups for the application and database instances.
Why this is correct
Cluster placement groups provide low-latency, high-throughput network.
- ✗
AWS Direct Connect to connect the application and database servers.
Why it's wrong here
Direct Connect is for on-premises to AWS, not within AWS.
- ✗
AWS Transit Gateway to connect the application and database subnets.
Why it's wrong here
Transit Gateway is for network transit between VPCs, not for low latency within a VPC.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company is designing a new SAP environment on AWS. The SAP application servers communicate with the database over the network. The architect wants to minimize latency and maximize throughput. Which placement strategy should the architect use?
easy- ✓ A.Place all servers in a single Availability Zone and use a cluster placement group.
- B.Place the application servers in one Availability Zone and the database in a different Availability Zone.
- C.Place the application servers in one VPC and the database in a different VPC connected via VPC peering.
- D.Place the application servers in one AWS Region and the database in another Region.
Why A: A cluster placement group is the correct choice because it provides the lowest possible latency and highest throughput by ensuring that all SAP application and database servers are placed in close physical proximity within a single Availability Zone. This placement minimizes network hops and leverages non-blocking, high-bandwidth networking, which is critical for SAP's latency-sensitive communication between application and database layers.
