PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is migrating its SAP ERP system to AWS and needs to minimize network latency between the SAP application servers and the database. Which AWS service or feature should be used to meet this requirement?
⚠ Common exam trap
Candidates often confuse network-level services like Global Accelerator or load balancers with physical proximity optimizations, mistakenly thinking they reduce inter-instance latency when they actually add network hops or are designed for external traffic optimization.
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
✓
Place the application and database servers in the same placement group.
Placement groups in AWS, specifically cluster placement groups, provide low-latency network performance by ensuring that EC2 instances are placed in close physical proximity within a single Availability Zone. This minimizes network latency between SAP application servers and the database, meeting the requirement for high-throughput, low-latency communication critical for SAP ERP workloads.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use AWS Global Accelerator for the application servers.
Why it's wrong here
Global Accelerator improves global user latency, not EC2-to-EC2 latency within the same region.
- ✓
Place the application and database servers in the same placement group.
Why this is correct
Placement groups provide low-latency, high-throughput networking between EC2 instances.
- ✗
Set up VPC peering between the application and database VPCs.
Why it's wrong here
VPC peering connects separate VPCs but does not guarantee low-latency communication compared to same-placement group.
- ✗
Use an Elastic Load Balancer in front of the application servers.
Why it's wrong here
ELB distributes incoming traffic, not internal instance communication.
