单选题在某台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 testRouter(dhcp-config) # network 192.168.3.0 0.0.0.63Router(dhcp-config) # ip dhcp excluded-address 192.168.3.62
B、 Router(config) # ip dhcp pool testRouter(dhcp-config) # network 192.168.3.0 255.255.255.192Router(dhcp-config) # ip dhcp excluded-address 192.168.3.62 255.255.255.254
C、 Router(config) # ip dhcp pool testRouter(dhcp-config) # network 192.168.3.0/26Router(dhcp-config) # ip dhcp excluded-address 192.168.3.62/29
D、 Router(config) # ip dhcp pool testRouter(dhcp-config) # network 192.168.3.0/26Router(dhcp-cofnig) # exitRouter(config) # ip dhcp excluded-address 192.168.3.56 192.168.3.62
