What is the DHCP address range configured for the DMZ interface?

• A. From 172.16.1.100 To 172.16.1.200
• B. From 172.16.1.1 To 172.16.1.50
• C. From 172.16.1.2 To 172.16.1.99
• D. From 192.168.1.100 To 192.168.1.200

Answer: (A)

Allocating a DHCP scope for a DMZ interface requires choosing a range within the DMZ subnet that avoids conflicts with devices that should have fixed addresses and provides enough addresses for hosts that will be added there. In many setups, the gateway or firewall interface uses the first address in the subnet (for example, 172.16.1.1). By starting the DHCP pool at 172.16.1.100, you avoid assigning the gateway address to clients and leave lower addresses free for any devices that need static IPs or for future network devices. The range 172.16.1.100 to 172.16.1.200 yields 101 usable addresses, which is a solid pool for DMZ hosts while keeping the lower end of the subnet reserved for essential devices. The other options either include common gateway addresses (like .1), use a lower range that might collide with static assignments, or place hosts on a different subnet that wouldn’t align with the DMZ interface.
