PAS-C01 Technology Practice Question
A company is deploying a new SAP S/4HANA system on AWS and needs to ensure that the application servers can communicate with the database servers securely and with low latency. The application servers and database servers are in different VPCs. Which AWS service should be used to connect these VPCs?
⚠ Common exam trap
Candidates often confuse VPC Peering with AWS Direct Connect, mistakenly thinking a dedicated connection is required for low latency, but Direct Connect is for on-premises connectivity, not VPC-to-VPC, and VPC Peering provides the same private, low-latency path within a region without additional cost or complexity.
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
✓
VPC Peering
VPC Peering is the correct choice because it establishes a direct network connection between two VPCs using AWS's internal infrastructure, enabling private IPv4 or IPv6 traffic with low latency and high throughput. For SAP S/4HANA, where application-to-database communication requires consistent sub-millisecond latency and avoids internet transit, VPC Peering provides the necessary Layer-3 connectivity without bandwidth bottlenecks or single points of failure. Unlike VPN or Direct Connect, VPC Peering does not introduce additional hop latency or third-party hardware, making it ideal for this intra-region, cross-VPC scenario.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS VPN
Why it's wrong here
VPN is for encrypted connections over the internet, not optimal for low latency.
- ✗
Amazon API Gateway
Why it's wrong here
API Gateway is for creating APIs, not VPC connectivity.
- ✓
VPC Peering
Why this is correct
VPC Peering provides direct, low-latency connectivity between VPCs.
- ✗
AWS Direct Connect
Why it's wrong here
Direct Connect connects on-premises to AWS, not VPC-to-VPC.
