Answer: AWS Transit Gateway

## Explanation **AWS Transit Gateway** is the correct solution because: - **Centralized Hub**: AWS Transit Gateway acts as a central hub that connects multiple VPCs and on-premises networks through a single network connection - **Simplified Network Architecture**: It eliminates the need for complex VPC peering connections between multiple VPCs - **Hybrid Connectivity**: Supports connections to on-premises networks via VPN or AWS Direct Connect - **Scalability**: Can connect thousands of VPCs and on-premises networks through a single gateway **Why other options are incorrect:** - **AWS Direct Connect**: Provides dedicated network connection to AWS but doesn't inherently connect multiple VPCs together - **VPC peering**: Only connects two VPCs directly and doesn't provide centralized connectivity for multiple VPCs and on-premises networks - **AWS Client VPN**: Provides secure remote access for individual users, not for connecting entire networks This solution is ideal for organizations needing to manage complex network architectures with multiple VPCs and hybrid cloud connectivity.
