采用DHCP分配IP地址无法做到（）。

A:合理分配IP地址资源 B:减少网管员工作量 C:减少IP地址分配出错可能性 D:提高域名解析速度

在某台Cisco路由器中定义了一个名为test的DHCP地址池(192.168.3.0/26)，并保留192.168.3.62/29的IP地址，下列正确的配置语句是

A:Router(config) # ip dhcp pool test B:Router(dhcp-config) # network 192.168.3.0 0.0.0.63 C:Router(dhcp-config) # ip dhcp excluded-address 192.168.3.62 D:Router(config) # ip dhcp pool test E:Router(dhcp-config) # network 192.168.3.0 255.255.255.192 F:Router(dhcp-config) # ip dhcp excluded-address 192.168.3.62 255.255.255.254 G:Router(config) # ip dhcp pool test H:Router(dhcp-config) # network 192.168.3.0/26 I:Router(dhcp-config) # ip dhcp excluded-address 192.168.3.62/29 J:Router(config) # ip dhcp pool test K:Router(dhcp-config) # network 192.168.3.0/26 L:Router(dhcp-cofnig) # exit M:Router(config) # ip dhcp excluded-address 192.168.3.56 192.168.3.62

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
