ANS-C01 Network Implementation Practice Question
Which THREE of the following are considerations when designing a multi-account VPC architecture using AWS Transit Gateway? (Choose 3.)
⚠ Common exam trap

Correct answer & explanation
✓
Transit Gateway can be integrated with Direct Connect Gateway
AWS Transit Gateway acts as a central hub for interconnecting VPCs and on-premises networks. It can be integrated with Direct Connect Gateway, allowing a single Direct Connect connection to reach multiple VPCs attached to the Transit Gateway, simplifying hybrid network design and reducing operational overhead.
