Quick Answer
The answer is AWS Transit Gateway, AWS Resource Access Manager (RAM), and AWS Organizations. These three services work together to enable centralized multi-account network management by allowing you to create a single Transit Gateway in a central account, then use RAM to share it with all member accounts in your AWS Organization, eliminating the need for complex VPC peering or duplicate infrastructure. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this scenario tests your understanding of how to design a hub-and-spoke topology at scale, often appearing as a multi-select question where common traps include choosing VPC Peering (which does not scale to hundreds of accounts) or Direct Connect Gateway (which handles on-premises, not inter-VPC connectivity). A strong memory tip is to think of the "TRiO" — Transit Gateway, RAM, and Organizations — as the three pillars that unlock centralized, scalable network management across accounts without manual cross-account IAM roles.
This ANS-C01 practice question tests your understanding of network design. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 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.)
AWS Resource Access Manager
Shares Transit Gateway and other resources across accounts.
AWS CloudFormation StackSets
Deploys networking resources consistently across multiple accounts.
VPC Peering
Why wrong: Point-to-point, not centralized.
AWS Direct Connect
Why wrong: Connects on-premises to AWS, not for multi-account VPC connectivity.
AWS Transit Gateway
Central hub for connecting VPCs across accounts.

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.
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 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.
Detailed technical explanation
AWS Transit Gateway acts as a hub-and-spoke router using a centralized routing table, supporting transitive routing between thousands of VPCs and on-premises networks via BGP. CloudFormation StackSets allow you to deploy infrastructure as code across multiple accounts and Regions in a single operation, ensuring consistent network configurations (e.g., Transit Gateway attachments, route tables) across the organization. RAM shares the Transit Gateway resource with other accounts, which then attach their VPCs, and the Transit Gateway handles all inter-VPC traffic using its route tables, avoiding the need for individual VPC Peering connections.
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.
