The answer is to use a Direct Connect Gateway and attach the VPCs. This is correct because a Direct Connect Gateway acts as a central hub that allows a single private virtual interface (VIF) to connect to multiple VPCs, even within the same AWS region, without requiring additional VIFs or multiple physical connections. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this scenario tests your understanding of how to scale Direct Connect connectivity efficiently, often appearing as a trap where candidates mistakenly consider creating extra VIFs or using VPC peering, which only handles inter-VPC routing rather than extending a single physical connection. A common memory tip is to think of the Direct Connect Gateway as a “multi-VPC adapter” for your private VIF—it enables one pipe to serve many VPCs, eliminating the need for redundant infrastructure.
ANS-C01 Network Implementation Practice Question
This ANS-C01 practice question tests your understanding of network implementation. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company has a Direct Connect connection with a private VIF to a VPC. They want to extend this connectivity to multiple VPCs in the same region without creating additional VIFs. Which solution should they implement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a Direct Connect Gateway and attach the VPCs
Option B is correct because a Direct Connect Gateway allows a single private VIF to connect to multiple VPCs in the same region. Option A is for hybrid connectivity but not for multi-VPC. Option C is for inter-VPC routing. Option D is for additional VIFs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Provision additional private VIFs for each VPC
Why it's wrong here
Additional VIFs increase complexity and cost.
✗
Use VPC peering between the VPCs
Why it's wrong here
VPC peering does not integrate with Direct Connect.
✗
Use a Transit VPC with VPN connections
Why it's wrong here
Transit VPC uses VPN, which may not provide the same performance as Direct Connect.
✓
Use a Direct Connect Gateway and attach the VPCs
Why this is correct
Direct Connect Gateway enables a single VIF to connect to multiple VPCs.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.

Variation 1. A company is using AWS Direct Connect with a private virtual interface (VIF) to connect its on-premises data center to a VPC. The VPC has a virtual private gateway (VGW) attached. The company has recently added a second VPC and wants to use the same Direct Connect connection to access both VPCs. The network engineer proposes using a Direct Connect gateway (DXGW) with two private VIFs, one for each VPC. However, the engineer wants to minimize complexity and cost. Which configuration should the engineer use to allow both VPCs to use the same Direct Connect connection?
medium
✓ A.Create a Direct Connect gateway and associate it with the private VIF. Then associate both VPCs' virtual private gateways with the Direct Connect gateway.
B.Create a private VIF for each VPC on the same Direct Connect connection.
C.Create a public virtual interface on the Direct Connect connection and attach both VPCs to it.
D.Create a single private VIF and attach both VPCs directly to it.
Why A: Option B is correct because a Direct Connect gateway can be associated with multiple VGWs from different VPCs, allowing a single private VIF to connect to multiple VPCs. Option A is incorrect because private VIF is needed, not public. Option C is incorrect because each VPC needs its own VGW. Option D is incorrect because multiple private VIFs increase cost and complexity.
