According to the practice exam, the correct answer is A

Options B, C, and D are not directly related to setting up secure network communication between CloudHub and the customer-provisioned AWS VPC:  Option B mentions API Whitelisting policies, which are typically used for controlling access to APIs but do not address VPC communication.  Option C discusses VM queues in the Mule application, which are used for messaging within the application but do not establish secure network communication between VPCs.  Option D talks about configuring an external identity provider (IdP) but doesn't address the requirement for private, secure network communication between CloudHub and the AWS VPC.

Connecting to your Anypoint VPC extends your corporate network and allows CloudHub workers to access resources behind your corporate firewall. * You can connect on-premises data centers through a secured VPN tunnel, or a private AWS VPC through VPC peering, or by using AWS Direct Connect.

A. Add a Mulesoft-hosted Anypoint VPC configured with VPC Peering to the AWS VPC

Should be A. VPC Peering. Cannot be C because being able to communicate securely with customer-provisioned AWS VPC has nothing to do with VM queues. Cannot be D because identity provider has nothing to do with secure communication Cannot be B because IP Whitelisting does not mean it is secure, it can still be intercepted and manipulated in transit.

A. VPC peering.
