In a Microsoft Azure VNet with the IP network 10.0.0.0/16, what is a valid IP address for the Palo Alto Networks NGFW’s management interface?

The valid IP address for the Palo Alto Networks NGFW’s management interface must fall within the defined range of the Azure Virtual Network (VNet) 10.0.0.0/16. This subnet allows for a range of IP addresses from 10.0.0.1 to 10.0.255.254, providing a total of 65,534 usable IP addresses.

When considering the answer, it's important to recognize that options A, B, and C all fall within the valid range of usable IP addresses for the subnet. Specifically, 10.0.1.254 is a usable address because it is not a network or broadcast address; rather, it is an individual IP that can be assigned to an interface, such as the management interface of the firewall.

Option D, 10.0.3.255, is not a valid address for assignment to a device's interface because it is designated as a broadcast address for the subnet 10.0.3.0/24. In IPv4 networking, the highest address in any subnet (where the last octet is .255 when the first three octets are the same) is reserved for broadcasting to all hosts in that subnet and cannot be assigned to
