- A
Create a VPN connection from each VPC to a central network appliance.
Why wrong: Does not scale and adds complexity.
- B
Use AWS PrivateLink to connect each VPC to a central VPC endpoint service.
Why wrong: PrivateLink is for service access, not full VPC-to-VPC routing.
- C
Create a Transit Gateway in the networking account and share it with other accounts using AWS Resource Access Manager.
Allows centralized management and self-service attachment via RAM.
- D
Create VPC peering connections between each VPC and a central VPC.
Why wrong: Number of peering connections grows quadratically, not manageable.

SAP-C02 Practice Question: Design Solutions for Organizational Complexity
This SAP-C02 practice question tests your understanding of design solutions for organizational complexity. 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 global company uses AWS Organizations with hundreds of accounts. The networking team needs to allow VPCs in different accounts to communicate privately using AWS Transit Gateway. The company wants to centralize management while allowing individual account owners to create and attach VPCs. Which solution meets these requirements?
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 Transit Gateway in the networking account and share it with other accounts using AWS Resource Access Manager.
Option C is correct because AWS Transit Gateway allows you to centralize network connectivity across multiple VPCs and accounts. By creating the Transit Gateway in the networking account and sharing it via AWS Resource Access Manager (RAM), you enable individual account owners to attach their VPCs to the shared Transit Gateway, achieving private communication while maintaining centralized management.
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 AWS PrivateLink (which is for service exposure, not general routing) with Transit Gateway, or assume VPC peering can be scaled via a central VPC, failing to recognize that peering is non-transitive and requires a full mesh for multi-VPC connectivity.
Detailed technical explanation
How to think about this question
AWS Transit Gateway uses a hub-and-spoke model with a single gateway that can route traffic between thousands of VPCs and on-premises networks via attachments. When shared via AWS RAM, the Transit Gateway remains owned by the networking account, but authorized accounts can create attachments in their own VPCs, with route tables in the Transit Gateway controlling inter-VPC traffic centrally. This design supports transitive routing, which VPC peering lacks, and avoids the complexity of managing numerous VPN tunnels or PrivateLink endpoints.
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.
