PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is planning to run SAP HANA on AWS and needs to ensure that the instance is optimally placed for low latency between the application and database tiers. Which AWS feature should be used?
⚠ Common exam trap
Candidates often confuse a cluster placement group with a spread placement group or partition placement group, assuming any placement group reduces latency, but only the cluster type is designed for low-latency, tightly coupled workloads like SAP HANA.

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
✓
Cluster placement group
A cluster placement group is the correct choice because it provides low-latency, high-throughput network connectivity by placing instances in a single Availability Zone with non-blocking, fully bisectioned bandwidth. For SAP HANA, where the application and database tiers require sub-millisecond latency for optimal performance, a cluster placement group ensures that all instances are physically close together, minimizing network hops and jitter.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Application Load Balancer
Why it's wrong here
Load balancers do not affect instance-to-instance latency.
- ✗
VPC endpoint
Why it's wrong here
VPC endpoints are for private connectivity to AWS services.
- ✓
Cluster placement group
Why this is correct
Cluster placement groups provide low-latency network performance within an AZ.
- ✗
Auto Scaling group
Why it's wrong here
Auto Scaling does not control placement.
