You have the Azure virtual machines shown in the following table. 

A DNS service is installed on VM1. You configure the DNS servers settings for each virtual network as shown in the following exhibit. 

You need to ensure that all the virtual machines can resolve DNS names by using the DNS service on VM1. What should you do? 

Answer options:

A. Configure a conditional forwarder on VM1
B. Add service endpoints on VNET1
C. Add service endpoints on VNET2 and VNET3
D. Configure peering between VNET1, VNET2, and VNET3

D

Virtual network peering enables you to seamlessly connect networks in Azure Virtual Network. The virtual networks appear as one for connectivity purposes. The traffic between virtual machines uses the Microsoft backbone infrastructure. Incorrect Answers: B, C: Virtual Network (VNet) service endpoint provides secure and direct connectivity to Azure services over an optimized route over the Azure backbone network. Endpoints allow you to secure your critical Azure service resources to only your virtual networks. Service Endpoints enables private IP addresses in the VNet to reach the endpoint of an Azure service without needing a public IP address on the VNet.
