This ANS-C01 practice question tests your understanding of network design. 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 virtual interface (VIF) to a VPC. The company wants to use the same Direct Connect connection to access multiple VPCs in the same AWS Region. Which solution should the company implement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a transit virtual interface on the Direct Connect connection and associate it with a Direct Connect gateway.
Option B is correct because a transit virtual interface (VIF) on a Direct Connect connection can be associated with a Direct Connect gateway, which enables connectivity to multiple VPCs in the same AWS Region. The Direct Connect gateway acts as a hub, allowing the single physical connection to route traffic to multiple VPCs via the transit VIF, without needing separate private VIFs for each VPC.
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.
✗
Use a public virtual interface and route traffic through the internet.
Why it's wrong here
Public VIF is for public services, not private VPC access.
✓
Create a transit virtual interface on the Direct Connect connection and associate it with a Direct Connect gateway.
Why this is correct
Transit VIF enables connectivity to multiple VPCs via Transit Gateway.
Related concept
Read the scenario before looking for a memorised answer.
✗
Request a hosted virtual interface from an AWS Direct Connect partner.
Why it's wrong here
Hosted VIF is still a private VIF tied to one VPC.
✗
Create additional private virtual interfaces for each VPC.
Why it's wrong here
Each private VIF is dedicated to a single VPC.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume you need a separate private virtual interface for each VPC, not realizing that a Direct Connect gateway with a transit VIF can aggregate multiple VPCs under a single physical connection, which is a key design pattern tested in the ANS-C01 exam.
Detailed technical explanation
How to think about this question
A transit virtual interface uses 802.1Q VLAN tagging and BGP to connect to a Direct Connect gateway, which then uses virtual private gateway (VGW) attachments to route traffic to multiple VPCs in the same Region. The Direct Connect gateway supports up to 10 VPC attachments per gateway (by default) and allows transitive routing between VPCs if configured, but by default it only provides connectivity from on-premises to each VPC. In a real-world scenario, this design simplifies network management and reduces costs by avoiding multiple physical connections or complex VPN overlays.

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.
