Question:

Which set of commands will configure a router as a DHCP server that will assign IPv4 addresses to the 192.168.100.0/23 LAN while reserving the first 10 and the last addresses for static assignment?

  • ip dhcp excluded-address 192.168.100.1 192.168.100.9
    ip dhcp excluded-address 192.168.101.254
    ip dhcp pool LAN-POOL-100
    ip network 192.168.100.0 255.255.254.0
    ip default-gateway 192.168.100.1
  • dhcp pool LAN-POOL-100
    ip dhcp excluded-address 192.168.100.1 192.168.100.9
    ip dhcp excluded-address 192.168.100.254
    network 192.168.100.0 255.255.254.0
    default-router 192.168.101.1
  • ip dhcp excluded-address 192.168.100.1 192.168.100.10
    ip dhcp excluded-address 192.168.100.254
    ip dhcp pool LAN-POOL-100
    network 192.168.100.0 255.255.255.0
    ip default-gateway 192.168.100.1
  • ip dhcp excluded-address 192.168.100.1 192.168.100.10
    ip dhcp excluded-address 192.168.101.254
    ip dhcp pool LAN-POOL-100
    network 192.168.100.0 255.255.254.0
    default-router 192.168.100.1

Explanation: The /23 prefix is equivalent to a network mask of 255.255.254.0. The network usable IPv4 address range is 192.168.100.1 to 192.168.101.254 inclusive. The commands dhcp pool, ip default-gateway, and ip network are not valid DHCP configuration commands.
