Hi, just have query regarding answer provided for this question.

Q. What happens when computers on a private network attempt to connect to the internet through a Cisco router running PAT?

Correct answer: The router uses the same IP address but a different TCP source port number for each connection.

I understand PAT is about port translation & assigning different port numbers to connections. But PAT is also another name for NAT which is about translating private addresses to public. Here we have a private network going through a PAT router so I assume it is using private addresses - these private addresses need to be translated to public so should the answer not be the option below:

The router assigns a unique IP address from a pool of legally registered addresses for the duration of the connection.

Thanks

I am trying to setup my home lab.

Its consists of 3 2610s, 2 2950s and 1 3550.

I want to use the 3550 as a layer 2 switch only (at this point).

Im having problems getting it to connect to the 2610.

I see the vlan 1 and fa0/1 (in switchport mode) up. But CDP isnt working.

Can someone point me in the right direction ? Output is given below ...

3550_1#show ip int br
Interface                  IP-Address      OK? Method Status                Protocol

I just took my CCNA recently after using this site and passed with a score over 930. I don't want to be specific because I'm paranoid.

Questions: It's hard to gauge how many related directly to the exam here, but I'd say maybe 50% to 75%, or possibly more if I just forgot & didn't recognize. There are >900 test questions to review and it takes a long time to review them all. I'm pretty sure there were new ones. I know they changed the ACL SIM (question QID:S17). Essentially they wanted me to allow x.x.x.2 instead of x.x.x.3. The name of the server they wanted to restrict was named Financial Accounting or something like that. Also, they wanted only this 1 host access via web browser, but wanted to block all other types of access from that computer & all other host computers + core. I wrote my access list like:

• access-list 100 permit tcp host [x.x.x.3 PC] host [x.x.x.17 server] eq 80
  
• access-list 100 deny ip any host [x.x.x.17 server]
  
• access-list 100 permit ip any any

I'm a little confused by the question:
An administrator is in the process of changing the configuration of a router.  What command will allow the administrator to check the changes that have been made prior to saving the new configuration?

Correct Answer: Router#show running-config

There's a very good chance that I'm misinterpreting this question, but shouldn't the admin be checking the startup-configuration if they want to compare before saving?  Unless the running-config hasn't been altered, wouldn't a sh run show their current configuration rather than prior?

I think I may need to lay down.

This site is swesome.  If I would have studied IPv6 more thoroughly I probably would have aced the exam.  Good luck to all who are preparing to sit for this exam.  You'll pass. 

Took and passed ICND2 with a score of 902 on my 1st attempt yesterday.

Prep time was 3 months (right after passing ICND1), and included TestOut LabSim CCNA course, CCNA ICND Exam Cert Guide by Wendell Odom, CBT Nuggets, and of course how2pass ICND2 practice tests. The two primary study materials were TestOut Labsim and how2pass.

lots of questions on the exam covered here... I didn't complete the access-list Sim or the EIGRP sim, but completed most of the EIGRP. I got a score of 920! Good luck you can do it!

I passed the route exam today with a score of 965.  I went through the networking academy, and after completion only used how2pass to prepare for the exam...  Just understand the reason behind the answers and you will be fine.

I worked on this question for the last two & got the respected outcome fine. But today, it acted a little strange??

The folowing details will highlight where I'm coming from;

As you can see I'ved saved in the config, router RIP version 2, but 'ip protocol' claims I was running version 1....Freaky or what.

Was there a problem on your servers today or something.

Even more freakishly it marked my answer right, which i was chuffed with.


Just though you Admin bods should know...

Keep up the good work...

The correct answer shows that  it is a  /22 ....  Just wandering if it should be /24 ?  Help  thanks
