- 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.
DXGW allows one VIF to reach multiple VPCs.
- B
Create a private VIF for each VPC on the same Direct Connect connection.
Why wrong: Multiple VIFs on same connection are possible but increase complexity.
- C
Create a public virtual interface on the Direct Connect connection and attach both VPCs to it.
Why wrong: Public VIF is for accessing public AWS services, not VPCs.
- D
Create a single private VIF and attach both VPCs directly to it.
Why wrong: A private VIF can only be attached to one VGW (or DXGW).
Question 1,067 of 1,705
Using Direct Connect Gateway for Multi-VPC Connectivity
This ANS-C01 practice question tests your understanding of network implementation. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 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?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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 the private VIF. Then associate both VPCs' virtual private gateways with the Direct Connect gateway.
Option A is correct because a Direct Connect gateway (DXGW) can be associated with a single private virtual interface (VIF) and then attached to multiple virtual private gateways (VGWs) in different VPCs, allowing both VPCs to use the same Direct Connect connection with minimal complexity and cost. Option B is incorrect because it requires creating two private VIFs, increasing cost and complexity. Option C is incorrect because a public VIF is used for accessing public AWS services, not for connecting to VPCs. Option D is incorrect because a single private VIF cannot be directly attached to multiple VPCs; a DXGW is needed to aggregate the connections.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.

Same concept, more angles
1 more ways 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 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?
hard- A.Provision additional private VIFs for each VPC
- B.Use VPC peering between the VPCs
- C.Use a Transit VPC with VPN connections
- ✓ D.Use a Direct Connect Gateway and attach the VPCs
Why D: A Direct Connect Gateway (DX Gateway) is a managed service that allows you to associate a single private virtual interface (VIF) with up to 10 VPCs in the same AWS Region (or across Regions with inter-region peering). This enables the company to extend their existing Direct Connect connection to multiple VPCs without provisioning additional VIFs, simplifying management and reducing costs.
