24在路由器上建立一个名为test的DHCP地址池，并为其分配IP地址202.112.7.0、24，子网地址中的202.112.7.2~202.112.7.10作为静态地址分配，正确的DHCP配置是
(A) Routerconfig#ip dhcp pool test Routerconfig#ip dhcp excluded-address 202.112.7.2-10 Routerdhcp-config#network 202.112.7.0 255.255.255.0
(B) Routerconfig#ip dhcp excluded-address 202.112.7.2-10 Routerconfig#ip dhcp pool test Routerdhcp-config#network 202.112.7.0/24
(C) Routerconfig#ip dhcp excluded-address 202.112.7.2-10 Routerconfig#ip dhcp pool test Routerdhcp-config#network 202.112.7.0 0.0.0.255
(D) Routerconfig#ip dhcp excluded-address 202.112.7.2-10 Routerconfig#ip dhcp pool test Routerdhcp-config#network 202.112.7.0 255.255.255.0
