PAS-C01 Technology Practice Question
An SAP customer is using AWS Direct Connect to connect their on-premises network to AWS. They have multiple SAP systems in different VPCs. The network team wants to centralize connectivity and simplify routing. Which AWS service should they use to connect all VPCs to the on-premises network?
⚠ Common exam trap
Many candidates confuse VPC Peering with transitive routing, mistakenly thinking that peering multiple VPCs to a Direct Connect VIF can centralize connectivity, but VPC Peering does not support transitive routing and cannot connect to a Direct Connect VIF directly.
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
✓
Use AWS Transit Gateway to connect all VPCs and the Direct Connect gateway
AWS Transit Gateway acts as a central hub that interconnects VPCs and on-premises networks via a Direct Connect Gateway. This allows the customer to attach multiple VPCs to a single Transit Gateway and connect that Transit Gateway to the Direct Connect Gateway, simplifying routing and eliminating the need for multiple Direct Connect Virtual Interfaces (VIFs) or complex peering arrangements.
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 a VPN connection from each VPC to the on-premises network
Why it's wrong here
VPN is not centralized and adds complexity.
- ✗
Use VPC Peering between each VPC and the Direct Connect VIF
Why it's wrong here
VPC Peering is point-to-point and does not scale.
- ✓
Use AWS Transit Gateway to connect all VPCs and the Direct Connect gateway
Why this is correct
Transit Gateway provides a hub for multiple VPCs and Direct Connect.
- ✗
Use AWS PrivateLink to connect services across VPCs
Why it's wrong here
PrivateLink is for service endpoints, not routing.
