ANS-C01 Network Design Practice Question
A company is using AWS Direct Connect to connect its on-premises data center to a VPC. The company wants to use private virtual interfaces (VIFs) to access multiple VPCs in the same AWS Region. Which AWS service should be used to simplify this connectivity?
⚠ Common exam trap
The ANS-C01 exam often tests the misconception that VPC peering can be used to extend Direct Connect connectivity to multiple VPCs, but peering does not support transitive routing and cannot be used with Direct Connect private VIFs 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
✓
Direct Connect gateway
A Direct Connect gateway allows you to associate multiple virtual private gateways (VGWs) or transit gateways in the same or different AWS accounts, enabling a single private virtual interface to connect to multiple VPCs in the same AWS Region. This simplifies connectivity by eliminating the need for separate VIFs per VPC and reduces operational overhead.
