For private virtual interfaces, you need one private virtual interface for each VPC to connect to from the AWS Direct Connect connection.

The correct answer is B. One. One Virtual Interface is enough for accessing the VPC's.

Explanation: When establishing an AWS Direct Connect connection, you can use private virtual interfaces to access your VPC resources. A private virtual interface is a virtual interface that is not advertised to the internet. It allows you to access your VPC resources privately from your on-premises network.

In this scenario, the AWS infrastructure has four VPCs, but it is not necessary to configure a virtual interface for each VPC. You can use a single virtual interface to access all the VPCs. This is because a virtual interface can be associated with multiple VPCs. Therefore, the correct answer is B.

Option A is incorrect because it assumes that no virtual interface is required, which is not true in this scenario.

Option C is incorrect because it assumes that a virtual interface is required for each VPC, which is not necessary.

Option D is incorrect because it assumes that two virtual interfaces are required for each VPC, which is also not necessary.
