Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

What is the logical breakup of a Virtual Network known as?

1. Hyper - V

2. SubNet

3. Virtual Router

4. Network Segment

The correct answer is: SubNet

The logical breakup of a Virtual Network is known as a SubNet. In an Azure context, a subnet is a range of IP addresses in your virtual network. Subnets allow you to segment the virtual network into smaller segments and organize the network in a way that helps manage resources and improve security. By separating resources into different subnets, you can control traffic flow and apply different security and configuration rules effectively. This setup is crucial for organizing network services and controlling network resources efficiently within the Azure infrastructure. While Hyper-V deals with virtualization technology and virtual machines, and a Virtual Router refers to a device that connects multiple networks and routes traffic, both serve different purposes in the networking architecture. Network segments may also seem relevant, but the specific term used within Azure to describe the subdivision of virtual networks is "SubNet."
