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.
Which TWO of the following are valid methods to connect multiple VPCs in the same AWS region? (Select TWO.)
VPC peering
Direct connection between two VPCs.
AWS Direct Connect
Why wrong: Connects on-premises to AWS.
VPC endpoints
Why wrong: For private access to AWS services.
Site-to-Site VPN
Why wrong: Connects on-premises to AWS.
Transit gateway
Central hub for multiple VPC connections.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
VPC peering
VPC peering (Option A) is a valid method to connect multiple VPCs in the same AWS region. It uses the AWS global network infrastructure to create a one-to-one, private IPv4 or IPv6 routing connection between two VPCs, allowing traffic to flow as if they were on the same network. This is a direct, non-transitive connection that does not require a separate transit hub.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates often confuse VPC endpoints (which are for service access) with VPC peering or transit gateway, or mistakenly think Direct Connect or Site-to-Site VPN can connect VPCs directly, when they are actually designed for hybrid connectivity.
Detailed technical explanation
VPC peering uses the existing AWS infrastructure without gateways or VPN appliances, and traffic stays within the AWS network. Transit Gateway (Option E) acts as a hub-and-spoke router, supporting transitive routing between thousands of VPCs and on-premises networks using a single gateway, which simplifies management and reduces the number of peering connections needed. Both methods support inter-region peering, but within the same region, they offer low-latency, high-bandwidth connectivity without additional data transfer costs.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
