Azure Fundamentals AZ-900 Practice Test 2

Explanation:
Networks in Azure are known as virtual networks. A virtual network can have multiple IP address spaces and multiple subnets. Azure automatically routes trafficbetween different subnets within a virtual network.
The question states that FinServer must be on a separate network segment. The only way to separate FinServer from the other servers in networking terms is toplace the server in a different virtual network to the other servers.
