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 an AWS Direct Connect connection and wants to connect to multiple VPCs in the same region. Which TWO services can be used to achieve this? (Choose TWO.)
VPC Peering
Why wrong: VPC Peering is direct VPC-to-VPC, not for Direct Connect.
AWS Transit Gateway
Transit Gateway can connect multiple VPCs and Direct Connect.
AWS Site-to-Site VPN
Why wrong: VPN can be used but is not required; Direct Connect is already private.
Direct Connect Gateway
Direct Connect Gateway allows a single Direct Connect connection to multiple VPCs.
AWS CloudHub
Why wrong: CloudHub is a VPN-based hub-and-spoke model.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
AWS Transit Gateway
AWS Transit Gateway (Option B) acts as a central hub that interconnects VPCs and on-premises networks via a single Direct Connect connection, allowing you to connect to multiple VPCs in the same region without needing individual virtual interfaces. Direct Connect Gateway (Option D) enables you to associate multiple VPCs in the same or different regions with a single Direct Connect connection by using a single private virtual interface (VIF) and transit virtual interfaces (VIFs) to reach those VPCs through Transit Gateway or virtual private gateways.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
The trap here is that candidates often confuse VPC Peering (Option A) as a way to extend Direct Connect connectivity to multiple VPCs, but VPC Peering does not support transitive routing and cannot be used to route traffic from Direct Connect to multiple VPCs without a central hub like Transit Gateway.
Detailed technical explanation
Under the hood, a Direct Connect Gateway (DXGW) is a globally available resource that can be associated with up to 10 Transit Gateways or virtual private gateways per region, allowing a single Direct Connect connection to reach multiple VPCs across accounts and regions. The Transit Gateway uses a transit virtual interface (VIF) to connect to the DXGW, and route tables within the Transit Gateway control traffic flow between attached VPCs and the on-premises network. A real-world scenario is a multi-account environment where a company uses a single Direct Connect connection to connect to dozens of VPCs spread across multiple AWS accounts, all managed through a central Transit Gateway and DXGW.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
