Answer: Create transit VIF with a gateway association to a new Direct Connect gateway. Associate each transit gateway with the new Direct Connect gateway.
To establish network connectivity from the on-premises data center to the AWS Regions and enable inter-VPC communications across different Regions, the most efficient solution involves using AWS Direct Connect in conjunction with AWS Transit Gateway. Option C is the correct choice because it suggests creating a transit VIF with a gateway association to a new Direct Connect gateway and then associating each transit gateway with the new Direct Connect gateway. This setup allows for the on-premises data center to connect to the AWS Regions through the Direct Connect connection, and the transit gateways facilitate inter-VPC communications across the different Regions. This solution leverages the scalability and flexibility of AWS Transit Gateway to manage the connectivity between thousands of VPCs and multiple Regions efficiently. Options A and B are not optimal because they limit the connectivity to a single VPC or require manual association with each VPC, which is not scalable for the company's needs. Option D is incorrect because it suggests using a Site-to-Site VPN connection with a public VIF, which is not the most efficient or cost-effective method for establishing connectivity in this scenario.

A company operates business applications on AWS, utilizing 50 AWS accounts, thousands of VPCs, and 3 AWS Regions spanning the United States and Europe. A network engineer must establish network connectivity between an on-premises data center and the AWS Regions, as well as enable connectivity between the VPCs. Users and applications on-premises must be able to access applications running in the VPCs. The company has an existing AWS Direct Connect connection available for use. The network engineer has created a transit gateway in each Region and configured them as inter-Region peers.
What solution will enable network connectivity from the on-premises data center to the AWS Regions and facilitate inter-VPC communication across the different Regions?
A
Create a private VIF with a gateway type of virtual private gateway. Configure the private VIF to use a virtual private gateway that is associated with one of the VPCs.
B
Create a private VIF to a new Direct Connect gateway. Associate the new Direct Connect gateway with a virtual private gateway in each VPC.
C
Create transit VIF with a gateway association to a new Direct Connect gateway. Associate each transit gateway with the new Direct Connect gateway.
D
Create an AWS Site-to-Site VPN connection that uses a public VIF for the Direct Connect connection. Attach the Site-to-Site VPN connection to the transit gateways.
