PAS-C01 Technology Practice Question
A company runs a critical SAP application on AWS. The SAP team needs to reduce network latency between application servers and the database. Which AWS service should be used to achieve this?
⚠ Common exam trap
Watch out — candidates often confuse AWS Global Accelerator (which improves latency for external users) with internal network optimization, or they assume VPC Peering provides performance benefits, when in fact only placement groups directly reduce latency between EC2 instances in the same Availability Zone.

Correct answer & explanation
✓
Placement Groups (cluster)
Placement Groups with a cluster placement strategy are designed to provide the lowest possible network latency and highest throughput by ensuring that EC2 instances are placed in a single Availability Zone with low-latency, high-bandwidth networking. For a critical SAP application where the application servers and database must communicate with minimal latency, a cluster placement group is the correct choice because it leverages non-blocking, fully bisectional bandwidth between instances, reducing network hops and jitter.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon Route 53
Why it's wrong here
Route 53 is a DNS service, not a network latency optimizer.
- ✗
AWS Global Accelerator
Why it's wrong here
Global Accelerator optimizes global traffic, not intra-region latency.
- ✗
VPC Peering
Why it's wrong here
VPC Peering connects VPCs but does not ensure low latency between instances.
- ✓
Placement Groups (cluster)
Why this is correct
Cluster placement groups place instances in a single AZ with low-latency networking.
