ANS-C01 Network Implementation Practice Question
A company is implementing a hybrid network using AWS Direct Connect and VPN backup. They have multiple VPCs in a single AWS Region. Which design minimizes the number of Direct Connect virtual interfaces while providing connectivity to all VPCs?
⚠ Common exam trap
Candidates often confuse Direct Connect gateway with transit VPC or assume that each VPC requires its own private VIF, overlooking the gateway's ability to consolidate connectivity across multiple VPCs in a single Region.
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 one private VIF attached to a Direct Connect gateway and associate the gateway with all VPCs.
A Direct Connect gateway allows a single private virtual interface (VIF) to connect to multiple VPCs in the same AWS Region. By attaching the Direct Connect gateway to all target VPCs, you eliminate the need for separate private VIFs per VPC, minimizing operational overhead and cost while maintaining private connectivity.
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 one private VIF attached to a Direct Connect gateway and associate the gateway with all VPCs.
Why this is correct
Direct Connect gateway enables multi-VPC connectivity over one VIF.
- ✗
Set up a transit VPC with EC2-based routers.
Why it's wrong here
Adds complexity and single point of failure.
- ✗
Create a separate private VIF for each VPC.
Why it's wrong here
Inefficient; each VIF requires separate BGP session.
- ✗
Use a single public VIF and route through the internet.
Why it's wrong here
Public VIF is for public IPs, not private connectivity.
