ANS-C01 Network Implementation Practice Question
A company needs to connect its on-premises network to a VPC using AWS Direct Connect. The company wants to use a single Direct Connect connection to connect to multiple VPCs in the same region. Which configuration should be used?
⚠ Common exam trap
Many candidates confuse the role of a Transit Gateway with a Direct Connect Gateway, assuming that a Transit Gateway alone can directly terminate a Direct Connect private VIF, when in fact a Direct Connect Gateway is required as an intermediary to aggregate multiple VPC attachments.
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
✓
Create a Direct Connect Gateway and associate it with multiple VPCs
A Direct Connect Gateway allows a single Direct Connect connection (via a private virtual interface) to be associated with multiple VPCs in the same region (or across regions). The Direct Connect Gateway acts as a hub, enabling transitive routing between the on-premises network and all associated VPCs without needing separate private VIFs per VPC.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a private VIF for each VPC
Why it's wrong here
Each private VIF connects to a single VPC, but you can create multiple VIFs on the same connection.
- ✗
Use a VPN connection to extend the Direct Connect to other VPCs
Why it's wrong here
VPN is not needed; Direct Connect Gateway handles multiple VPCs.
- ✗
Use a Transit Gateway to connect the Direct Connect to multiple VPCs
Why it's wrong here
Transit Gateway can be attached to Direct Connect Gateway, but the Direct Connect Gateway itself allows multiple VPC attachments.
- ✓
Create a Direct Connect Gateway and associate it with multiple VPCs
Why this is correct
A Direct Connect Gateway can be associated with up to 10 VPCs per region.

Same concept, more angles
1 more way this is tested on ANS-C01
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company has an AWS Direct Connect connection and wants to connect to multiple VPCs in the same region. Which TWO services can be used to achieve this? (Choose TWO.)
easy- A.VPC Peering
- ✓ B.AWS Transit Gateway
- C.AWS Site-to-Site VPN
- ✓ D.Direct Connect Gateway
- E.AWS CloudHub
Why B: AWS Transit Gateway (Option B) acts as a central hub that interconnects VPCs and on-premises networks via a single Direct Connect connection, allowing you to connect to multiple VPCs in the same region without needing individual virtual interfaces. Direct Connect Gateway (Option D) enables you to associate multiple VPCs in the same or different regions with a single Direct Connect connection by using a single private virtual interface (VIF) and transit virtual interfaces (VIFs) to reach those VPCs through Transit Gateway or virtual private gateways.
