Question

You have configured the DHCP server on a FortiGate's port1 interface (or internal, depending on the model) to offer IPs in a range of 192.168.1.65-192.168.1.253. When the first host sends a DHCP request, what IP will the DHCP offer?

Options

  • A192.168.1.99
  • B192.168.1.253
  • C192.168.1.65
  • D192.168.1.66

Why each option

When a FortiGate DHCP server is configured with an IP range, it typically offers the lowest available IP address to the first requesting client.

A192.168.1.99

192.168.1.99 is an arbitrary IP within the range and is not the first address typically offered by a DHCP server.

B192.168.1.253

192.168.1.253 is the last IP address in the defined range and would only be offered after all lower addresses have been leased.

C192.168.1.65Correct

FortiGate DHCP servers, like most standard DHCP implementations, allocate IP addresses sequentially from the beginning of the configured pool. Therefore, 192.168.1.65, being the lowest address in the range, will be offered first.

D192.168.1.66

192.168.1.66 is the second IP address in the range and would only be offered if 192.168.1.65 was already leased or reserved.
