ANS-C01 Network Implementation Practice Question
A company has multiple VPCs that need to communicate with each other and with an on-premises network via AWS Transit Gateway. Which THREE of the following are valid attachment types for a transit gateway?
⚠ Common exam trap
The ANS-C01 exam often tests the misconception that any AWS networking component can be attached to a Transit Gateway, but only VPCs, Site-to-Site VPN connections, and Direct Connect Gateways are valid attachment types.
