Microsoft Azure Administrator — Question 113

You have an Azure virtual network named VNet1 that contains the following settings:

• IPv4 address space: 172.16.10.0/24
• Subnet name: Subnet1
• Subnet address range: 172.16.10.0/25

What is the maximum number of virtual machines that can connect to Subnet1?

Answer options

Correct answer: C

Explanation

The correct answer is C, as a /25 subnet allows for 128 IP addresses, but two are reserved for network and broadcast addresses, leaving 126 usable addresses. However, the total maximum number of virtual machines that can connect is based on the overall address space of the VNet, which can accommodate 123 VMs when considering further configurations and reservations. The other options are incorrect because they do not accurately reflect the usable IPs in the given subnet setting.
