[单选题]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．Router(config)#ip dhcp pool test Router(config)#ip dhcp excluded-address 202.112.7.2-10 Router(dhcp-config)#network 202.112.7.0 255.255.255.0

B．Router(config)#ip dhcp excluded-address 202.112.7.2-10 Router(config)#ip dhcp pool test Router(dhcp-config)#network 202.112.7.0/24

C．Router(config)#ip dhcp excluded-address 202.112.7.2-10 Router(config)#ip dhcp pool test Router(dhcp-config)#network 202.112.7.0 0.0.0.255

D．Router(config)#ip dhcp excluded-address 202.112.7.2-10 Router(config)#ip dhcp pool test Router(dhcp-config)#network 202.112.7.0 255.255.255.0
