Configuration -
Ra(config)#access-list 2 permit 10.1.1.0 0.0.0.255
Ra(config)#line vty 0 4
Ra(config)#access-class 2 in
From the above configuration one thing is clear that only
host from 10.1.1.0 network (i.e Switch 2)can access the telnet.
Host from 10.1.2.0 network are not allowed to access the
TELNET. As the access list specified on vitual terminal ie.
line vty 0 4.
So [B] is the correct answer.
[B] To prevent sw1 host from accessing command prompt
I configure ur scenario in PACKET TRACER & configure
accordingly.
After that i tried to access TELNET from client of Switch2,
i wz successful. Ie. Router allow to access the TELNET.
After that i tried to access TELNET from client of Switch1,
i wzn't successful.Ie Router doesn't allow to access the TELNET.
On the option, it create little bit confusion on mind..
COMMAND PROMPT of which device... off course its ROUTER.
If the option were written in specific, than i think no
confusion will arise.
I hope, it will help u..!!
Let me know my feedback..!!
thanxx for such a gud question.
