PAS-C01 VPC Network Practice Question
A company is running SAP NetWeaver on AWS. The SAP application server instances need to be distributed within a single Availability Zone for low-latency connectivity. Which AWS feature should be used to ensure low-latency connectivity between these instances?
⚠ Common exam trap
The trap is selecting other network features such as VPC Peering or Internet Gateway, which do not directly improve latency between instances. The correct choice for low-latency within an AZ is a cluster placement group.

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 Group (cluster)
A cluster placement group places instances into a low-latency, high-bandwidth network within a single Availability Zone. This is ideal for SAP application servers that require these characteristics. For multi-AZ high availability, a separate placement group per AZ or spread placement groups may be considered, but for the requirement stated in this question, the cluster placement group (Option B) is correct.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Network ACL
Why it's wrong here
Network ACL is a stateless firewall that controls traffic at the subnet level; it does not affect network latency or connectivity between instances.
- ✓
Placement Group (cluster)
Why this is correct
Placement Group (cluster) places instances in a single Availability Zone for low latency; it does not support distribution across multiple AZs.
- ✗
Internet Gateway
Why it's wrong here
Internet Gateway enables internet access for instances; it does not provide low-latency connectivity between internal instances.
- ✗
VPC Peering
Why it's wrong here
VPC Peering connects two different VPCs; it is not needed for instances within the same VPC and can introduce additional latency.
