- A
Use a Direct Connect Gateway
Direct Connect Gateway enables multi-VPC connectivity across regions over the same private VIF.
- B
Create a new private VIF for the second VPC
Why wrong: This adds complexity and cost; a Direct Connect Gateway is simpler.
- C
Use a VPN over the internet to connect the VPCs
Why wrong: This bypasses the Direct Connect advantage of a private connection.
- D
Set up VPC peering between the two VPCs
Why wrong: VPC peering does not use Direct Connect; traffic would go over the internet.

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 use the same connection to access another VPC in a different region. What is the simplest way to achieve this?

Correct answer & explanation
✓
Use a Direct Connect Gateway
A Direct Connect Gateway (DX Gateway) allows you to associate a single private virtual interface (VIF) with multiple VPCs, even across different AWS regions. This is the simplest solution because it avoids creating additional VIFs or complex inter-VPC connectivity, and it supports transitive routing between the on-premises network and all associated VPCs via the same Direct Connect connection.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Create a new private VIF for the second VPC
Why it's wrong here
This adds complexity and cost; a Direct Connect Gateway is simpler.
- ✗
Use a VPN over the internet to connect the VPCs
Why it's wrong here
This bypasses the Direct Connect advantage of a private connection.
- ✗
Set up VPC peering between the two VPCs
Why it's wrong here
VPC peering does not use Direct Connect; traffic would go over the internet.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The ANS-C01 exam often tests the misconception that a private VIF is tied to a single VPC or region, leading candidates to incorrectly choose creating a new VIF for each VPC, when a Direct Connect Gateway is the designed solution for multi-VPC and multi-region connectivity.
Detailed technical explanation
How to think about this question
A Direct Connect Gateway acts as a regional hub that can be associated with up to 10 VPCs (by default) across different AWS regions, using a single private VIF. It uses BGP to propagate routes between the on-premises network and all associated VPCs, enabling seamless Layer 3 connectivity without requiring transit VPCs or additional VPN tunnels. In real-world scenarios, this is critical for multi-region disaster recovery setups where on-premises systems need low-latency access to workloads in multiple regions.
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.
TExam Day Tips
- 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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
