Answer: AWS Transit Gateway

## Explanation **AWS Transit Gateway** is the correct service for connecting multiple VPCs. Here's why: - **AWS Transit Gateway** acts as a central hub that can connect multiple VPCs, on-premises networks, and AWS services through a single gateway - It simplifies network architecture by eliminating the need for complex VPC peering connections **Why the other options are incorrect:** - **AWS Config**: A service for assessing, auditing, and evaluating AWS resource configurations (not for networking) - **AWS Direct Connect**: A service for establishing dedicated network connections from on-premises to AWS (not for VPC-to-VPC connectivity) - **Amazon GuardDuty**: A threat detection service that monitors for malicious activity and unauthorized behavior (not a networking service) **Key Benefits of AWS Transit Gateway:** - Centralized management of VPC connectivity - Simplified network topology - Scalable solution for connecting multiple VPCs across different AWS accounts and regions - Support for routing policies and network segmentation
