For DHCP pool NOCC on 192.168.20.0/24, configure the DHCP default gateway as the next-to-last usable address. Which command is required?

The default-router command within DHCP pool configuration specifies the default gateway that DHCP clients will receive. For the 192.168.20.0/24 network, the usable IP addresses range from 192.168.20.1 to 192.168.20.254. The last usable address is 192.168.20.254, making the next-to-last usable address 192.168.20.253. Incorrect options: next-server is used for specifying the TFTP server for network booting, not the default gateway. network defines the network address and subnet mask for the DHCP pool itself; the "secondary" keyword is for assigning a secondary IP address to an interface, not for defining a default gateway within a DHCP pool. ip default-gateway is a global configuration command used to set a default gateway for the router itself when it's not routing, not for clients obtaining addresses from a DHCP pool. The syntax provided is also incorrect.
