PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is migrating an SAP Business Suite system to AWS. The system has a large database and requires high network throughput between the application and database tiers. Which Amazon EC2 placement group strategy should be used?
⚠ Common exam trap
A common mix-up: candidates confuse placement groups and assume a spread or partition group provides better fault isolation, but for SAP workloads requiring high network throughput, the cluster placement group's low-latency and high-bandwidth characteristics are the primary requirement, not fault domain separation.

Correct answer & explanation
✓
Cluster placement group
A cluster placement group is the correct choice because it provides low-latency, high-throughput networking by placing all instances in a single Availability Zone within the same logical rack. For SAP Business Suite with a large database, the application and database tiers require high network throughput (e.g., up to 100 Gbps for supported instance types) and minimal latency, which a cluster placement group delivers by ensuring all instances are in close physical proximity. In contrast, a spread placement group distributes instances across distinct hardware to reduce risk of simultaneous failure but does not optimize network performance. A partition placement group spreads instances across logical partitions to isolate failures but also lacks the high-bandwidth, low-latency benefits of a cluster group. Using no placement group may result in instances being placed on separate racks, increasing network latency and reducing throughput.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Spread placement group
Why it's wrong here
Spread groups are for high availability, not low latency.
- ✗
Partition placement group
Why it's wrong here
Partition groups are for large distributed systems, not low latency.
- ✓
Cluster placement group
Why this is correct
Cluster groups provide low-latency, high-throughput within an AZ.
- ✗
No placement group
Why it's wrong here
Without a placement group, network performance may be variable.
