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.
