ANS-C01 Network Design Practice Question
A company is designing a hybrid network with AWS Direct Connect. They have multiple VPCs in the same Region and want to use a single Direct Connect connection to access all VPCs. Which AWS resource should be used?
⚠ Common exam trap
It's easy for candidates to confuse the Direct Connect Gateway with the Transit Gateway, thinking the Transit Gateway alone can terminate the Direct Connect connection, but the Transit Gateway requires a Direct Connect Gateway (via a transit VIF) to be attached to the Direct Connect link.

Correct answer & explanation
✓
Direct Connect Gateway
A Direct Connect Gateway allows you to associate up to 10 Virtual Private Gateways (VGWs) or Transit Gateways in the same or different AWS accounts, enabling a single Direct Connect connection to reach multiple VPCs in the same Region. This is the correct resource because it acts as a hub that terminates the Direct Connect virtual interfaces (VIFs) and propagates routes to the associated VPCs via their VGWs or Transit Gateways.

Variation 1. A company is designing a hybrid network using AWS Direct Connect. They want to extend their on-premises network to multiple VPCs in the same AWS Region. Which resource should they use to achieve this?
easy- A.Direct Connect transit virtual interface
- ✓ B.Direct Connect gateway
- C.Direct Connect private virtual interface (VIF)
- D.Link Aggregation Group (LAG)
Why B: A Direct Connect gateway is the correct resource because it allows you to associate up to 10 VPCs (or 20 with a quota increase) in the same or different AWS Regions with a single Direct Connect connection. It acts as a central hub, enabling connectivity from your on-premises network to multiple VPCs via a single private virtual interface (VIF) attached to the Direct Connect gateway, without needing separate VIFs per VPC.
