Hi, Weidong.
Yes, that's the main point I ask this question, as I feel that "no ip
domain-lookup" disables all possibility for other services that the
question not mentioned to do. It just mentions"typos", that seems any
config type wrongly won't translated to telnet or else so I feel the answer
is b).
But the answer is a).
Thx,
BBD (Big Black Dog)

The question is tricky. I'd like to ask procotor to clerify.
If you go with a), you cann't use command like 'ping www.cisco.com'. If you
go with b), the following is result: (fast response)
rtr#ping www.cisco.com
Translating "www.cisco.com"...domain server (MY DNS IP) [OK]
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 198.133.219.25, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 156/156/156 ms
ds1.bb.rtr#ping www.cisco.co
Translating "www.cisco.co"...domain server (MY DNS IP)
% Unrecognized host or address, or protocol not running.
