Question
A company has two virtual networks (VNets) that reside in the same Azure region.
An administrator reports that virtual machines (VMs) in each VNet are unable to connect to VMs in the other VNet.
You need to configure a connection between the two networks that maximizes throughput and minimizes latency.
What should you do?
A. Create a point-to-site VPN connection.
B. Configure a VPN gateway.
C. Create a site-to-site VPN connection.
D. Configure virtual network peering.
Answer
D. Configure virtual network peering.
Explanation
Virtual network peering is the most efficient way to connect two VNets in the same Azure region. It enables direct, low-latency connectivity between VMs in different VNets, as if they were part of the same network. Peering uses the Microsoft backbone infrastructure, ensuring high bandwidth and minimal latency.
Other options, such as VPN connections (point-to-site or site-to-site) and VPN gateways, introduce additional overhead and complexity. They require traffic to traverse the public internet or a VPN tunnel, resulting in increased latency and reduced throughput compared to peering.
By configuring virtual network peering, the VMs in both VNets can communicate directly using private IP addresses, without the need for public IP addresses or additional networking components. This streamlines the connection, optimizes performance, and simplifies management.
