ANS-C01 Network Design Practice Question
A company wants to connect multiple VPCs across different AWS accounts to a common on-premises network using AWS Transit Gateway. Which resource should be used to allow cross-account VPC attachments?
⚠ Common exam trap
A common mix-up: candidates confuse AWS Organizations with the actual resource sharing mechanism, forgetting that Organizations alone does not share resources—RAM is required to perform the cross-account sharing of Transit Gateways.

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
✓
AWS Resource Access Manager (RAM)
AWS Resource Access Manager (RAM) enables you to share a Transit Gateway with other AWS accounts within your organization or externally. Once shared, the recipient account can attach its VPCs to the shared Transit Gateway, allowing cross-account VPC attachments to a common on-premises network.
