SAP-C02 Practice Question: Design Solutions for Organizational Complexity
A company has a multi-account AWS environment and wants to implement a secure, scalable cross-account network architecture using AWS Transit Gateway. Which TWO steps should be taken?
⚠ Common exam trap
It's easy for candidates to confuse VPC endpoints (used for service access) with Transit Gateway (used for VPC-to-VPC routing), or assume VPC peering is sufficient for multi-account scalability despite its non-transitive nature and management overhead.
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 a central networking account and share it with other accounts using AWS Resource Access Manager
AWS Transit Gateway must be created in a central networking account and then shared with other accounts using AWS Resource Access Manager (RAM) to enable cross-account connectivity without VPC peering. This centralizes routing and simplifies network management across multiple VPCs and accounts.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deploy VPC endpoints in each account for communication
Why it's wrong here
VPC endpoints are for accessing AWS services privately, not for inter-VPC routing.
- ✓
Create a Transit Gateway in a central networking account and share it with other accounts using AWS Resource Access Manager
Why this is correct
RAM allows sharing the Transit Gateway with other accounts.
- ✓
Create VPC attachments in each account to connect to the shared Transit Gateway
Why this is correct
VPC attachments connect each VPC to the Transit Gateway.
- ✗
Establish VPC peering connections between each account and the central networking account
Why it's wrong here
Transit Gateway eliminates the need for VPC peering.
- ✗
Set up AWS Direct Connect between all accounts
Why it's wrong here
Direct Connect is for on-premises connectivity, not inter-account.
