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 company has a centralized networking team that manages a shared VPC with multiple AWS Transit Gateway attachments. Application teams create VPCs in separate AWS accounts and want to connect to the shared VPC. The networking team needs to ensure that only authorized VPCs can connect to the shared VPC. What is the MOST secure and scalable way to manage this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS Resource Access Manager to share the Transit Gateway with the application accounts.
AWS Resource Access Manager (RAM) allows the centralized networking team to share the Transit Gateway with specific application accounts, enabling authorized VPCs to create attachments without exposing the resource to all accounts. This approach is secure because it uses resource-based policies to grant access only to designated accounts, and scalable because it avoids the administrative overhead of managing individual VPNs or VPC peering connections as the number of application VPCs grows.
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.
✗
Use a VPN connection from each application VPC to the shared VPC.
Why it's wrong here
VPN is more complex and has bandwidth limitations.
✓
Use AWS Resource Access Manager to share the Transit Gateway with the application accounts.
Why this is correct
RAM allows sharing the Transit Gateway, and the networking team can accept or reject attachments via RAM.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use VPC peering between the shared VPC and each application VPC.
Why it's wrong here
VPC peering is not transitive and does not scale to many VPCs.
✗
Create IAM roles in each application account that allow the networking team to create VPC attachments.
Why it's wrong here
This would give the networking team excessive privileges and is not scalable.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse IAM permissions (Option D) with resource-based sharing via RAM, thinking that granting IAM roles to create attachments is sufficient, but RAM provides explicit authorization at the resource level, which is more secure and scalable for cross-account access.
Detailed technical explanation
How to think about this question
AWS Transit Gateway uses a hub-and-spoke model where attachments are created in the Transit Gateway owner account, and RAM shares the Transit Gateway with other accounts, allowing them to create attachments in their own VPCs. The Transit Gateway route tables can then be configured to control traffic flow, and RAM ensures that only authorized accounts can create attachments, providing a secure and scalable multi-account networking solution. In a real-world scenario, this is commonly used in large enterprises with hundreds of application accounts, where manual VPN or VPC peering management would be impractical.

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.
