Which three Cisco IOS commands are required to configure a voice gateway as a DHCP server to support a data subnet with the IP address of 10.1.30.0/24 and a default gateway of 10.1.30.1/24? (Choose three.)
A. ip dhcp pool
B. subnet 10.1.30.1 255.255.255.0
C. ip dhcp pool data
D. network 10.1.30.1/24
E. network 10.1.30.0 255.255.255.0
F. default-gw 10.1.30.1/24
G. default-router 10.1.30.1
Correct Answer: CEG
Explanation/Reference:
1) To configure the DHCP address pool name and enter DHCP pool configuration mode, use the following command in global configuration modE.
Router(config)# ip dhcp pool name – Creates a name for the DHCP Server address pool and places you in DHCP pool configuration mode
2) To configure a subnet and mask for the newly created DHCP address pool, which contains the range of available IP addresses that the DHCP Server may assign to clients, use the following command in DHCP pool configuration modE.
Router(dhcp-config)# network network-number [mask | /prefix-length] – Specifies the subnet network number and mask of the DHCP address pool. The prefix length specifies the number of bits that comprise the address prefix. The prefix is an alternative way of specifying the network mask of the client. The prefix length must be preceded by a forward slash (/).
3) After a DHCP client has booted, the client begins sending packets to its default router. The IP address of the default router should be on the same subnet as the client. To specify a default router for a DHCP client, use the following command in DHCP pool configuration modE.
Router(dhcp-config)# default-router address [address2 … address8] – Specifies the IP address of the default router for a DHCP client. One IP address is required; however, you can specify up to eight addresses in one command line.
