ANS-C01 Network Implementation Practice Question
A company wants to securely connect multiple VPCs in the same region to a common on-premises network using a single Direct Connect connection. Which AWS service should they use to simplify the network architecture?
⚠ Common exam trap
Many exam-takers confuse Transit Gateway with Direct Connect Gateway, assuming Transit Gateway alone can aggregate multiple VPCs under a single Direct Connect connection, but Transit Gateway requires a Direct Connect Gateway to terminate the Direct Connect virtual interface, making Direct Connect Gateway the correct answer for simplifying the architecture with a single connection.

Correct answer & explanation
✓
Direct Connect Gateway
A Direct Connect Gateway allows you to associate multiple VPCs (in the same or different AWS regions) with a single AWS Direct Connect connection, enabling connectivity to a common on-premises network. This simplifies the architecture by eliminating the need for multiple virtual interfaces or separate Direct Connect connections per VPC. The Direct Connect Gateway acts as a hub that routes traffic between the on-premises network and all associated VPCs via a single private virtual interface (VIF).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Virtual Private Gateway
Why it's wrong here
VGW attaches to one VPC; it does not support multiple VPCs.
- ✓
Direct Connect Gateway
Why this is correct
Direct Connect Gateway enables multiple VPCs to use a single Direct Connect connection.
- ✗
VPC Peering
Why it's wrong here
VPC peering does not involve Direct Connect.
- ✗
Transit Gateway
Why it's wrong here
Transit Gateway is for VPC and VPN connectivity, but Direct Connect Gateway is needed for Direct Connect.
