Virtual Networking & Route Configuration (VNet Peering)

Assess interconnectivity and routing requirements across virtual networks:

Domain 4: Configure & Manage Virtual Networks Sample Question 1 of 1

You have two virtual networks in the same Azure region: VNet1 (10.1.0.0/16) and VNet2 (10.2.0.0/16). You configure a VNet Peering between them. However, VMs in VNet1 cannot ping or reach VMs in VNet2. NSG inbound/outbound rules permit the required traffic. What is the most likely cause of this issue?

A

VNet peerings strictly require a dedicated VPN Gateway configured in each VNet.

B

The peering status must show as 'Connected' on BOTH sides of the reciprocal peering links.

C

The VNets must belong to distinct Azure tenants to support peering.

D

TCP and UDP protocols are disabled across peered VNets by default.

✓ Official Explanation: (B) Virtual network peering requires two separate link configurations (VNet1 -> VNet2 and VNet2 -> VNet1). Connectivity is only established once both individual peering states transition to 'Connected'.
