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 is designing a hybrid network using AWS Direct Connect. The company has a single 1 Gbps dedicated connection and wants to connect to multiple VPCs in the same region. Which THREE steps are necessary to achieve this connectivity?
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.
Option A is correct because a Direct Connect gateway acts as a central hub that allows a single private virtual interface to connect to multiple VPCs in the same or different AWS regions. Without a Direct Connect gateway, a private virtual interface can only connect to a single VPC. By using a Direct Connect gateway, you can associate it with multiple VPCs (either directly or via a transit gateway), enabling the desired multi-VPC connectivity over the single 1 Gbps dedicated connection.
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
The trap here is that candidates often confuse the need for multiple private virtual interfaces (one per VPC) with the correct architecture, not realizing that a Direct Connect gateway combined with a transit gateway enables a single private virtual interface to serve multiple VPCs, and that a transit virtual interface is required to connect the Direct Connect gateway to the transit gateway.
Detailed technical explanation
How to think about this question
Under the hood, a Direct Connect gateway is a globally available resource that can be associated with up to 10 virtual private gateways (VGWs) or transit gateways per region, and it uses BGP to exchange routes between the on-premises network and the attached VPCs. The transit virtual interface (option E) is a specific type of virtual interface that connects the Direct Connect gateway to a transit gateway, which then allows transitive routing between multiple VPCs attached to the transit gateway. In a real-world scenario, this design is common for enterprises with multiple VPCs that need centralized connectivity and traffic segmentation, as the transit gateway provides route tables and attachments for each VPC.
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.
