i think it should be the first 2 bits.notice that "to be summaried".we know the summaried address is 172.16.0.0,it use the the first 3 bits to devide the subnet to 6 nets.due to the given situaton,the first 2 bits are summaried. i used to find the question in the CCDA true test and i passed it.

You can summarize on the first bit but you would need two summary address statements to cover all 4 networks: 172.16.0.0 mask 255.255.128.0 for the networks 172.16.0.0 and 172.16.64.0 172.16.128.0 mask 255.255.128.0 for the network 172.16.128.0 and 172.16.192.0 Regards, No Shut It would be the
