The correct answer is to create a Transit Gateway in the networking account and share it with other accounts using AWS Resource Access Manager. This solution works because RAM allows you to share the Transit Gateway as a resource across hundreds of accounts in AWS Organizations without creating complex peering or VPN meshes, while still letting individual account owners self-service attach their own VPCs. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of centralized network management at scale, often appearing as a trap where candidates mistakenly choose VPC peering or VPNs—both of which fail to scale to hundreds of accounts. A key memory tip is to think of RAM as the “glue” that turns a single Transit Gateway into a shared hub, enabling the “hub-and-spoke” model without manual cross-account setup.
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 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 D is correct because it allows centralized management with self-service via Resource Access Manager. Option A is wrong because VPNs are not scalable. Option B is wrong because VPC peering does not scale to hundreds of accounts. Option C is wrong because VPC endpoints are for services, not VPC-to-VPC.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Create a VPN connection from each VPC to a central network appliance.
Why it's wrong here
Does not scale and adds complexity.
✗
Use AWS PrivateLink to connect each VPC to a central VPC endpoint service.
Why it's wrong here
PrivateLink is for service access, not full VPC-to-VPC routing.
✓
Create a Transit Gateway in the networking account and share it with other accounts using AWS Resource Access Manager.
Why this is correct
Allows centralized management and self-service attachment via RAM.
Related concept
Read the scenario before looking for a memorised answer.
✗
Create VPC peering connections between each VPC and a central VPC.
Why it's wrong here
Number of peering connections grows quadratically, not manageable.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.
