ANS-C01 Network Design Practice Question

A company is designing a network for a multi-account AWS environment using AWS Organizations. They need to centralize network management and enable VPC connectivity across accounts. Which THREE services should they consider? (Choose THREE.)

⚠ Common exam trap

The trap here is that candidates often select VPC Peering because it is a familiar, simple connectivity option, but they overlook that it lacks transitive routing and centralized management, making it unsuitable for a multi-account architecture where AWS Transit Gateway is the correct scalable solution.

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

AWS Resource Access Manager

AWS Resource Access Manager (RAM) is correct because it enables you to share centrally managed resources, such as Transit Gateways and VPC subnets, across multiple AWS accounts within an AWS Organization. This eliminates the need to create duplicate resources in each account and allows for centralized network management without requiring cross-account IAM roles or complex peering configurations.
