A B C D Cisco Technical Information Center (TIC) web site Cisco Technical Assistance Center (TAC) web site Cisco Center for Assisted Troubleshooting (CAT) web site Cisco Internetworking Troubleshooting Center (ITC) web site Answer: B Explanation: this is an obvious question as this is the name of the cisco technical assistance web site To me this is an easy question and no problem to verify as I did by going to the Cisco site just to be thorough Example: http://www.cisco.com/en/US/support/index.html QUESTION NO: When troubleshooting a complex problem which troubleshooting approach is used? A B C D Top-down Bottom-up Split-difference Divide-and-conquer Answer: B Explanation: This is a Cisco recommended technique for troubleshooting and it is a good way none-the-less I have designed digital electronics in a previous career and this is the quickest way to get to the root of the problem Any other way would simply be a waste of time If you go to this site you will see that this is precisely the way Cisco recommends to troubleshoot an issue They dissect it which is divide and conquer all the way Leading the way in IT testing and certification tools, www.testking.com -3- 642 - 831 Example: http://www.cisco.com/en/US/products/hw/routers/ps352/products_installation_and_configuration_guide_chapte r09186a008007e1d1.html#21487 QUESTION NO: What does a logical layered network model allows a troubleshooter to do? A B C D Focus on physical layers to isolate a problem Focus on specific elements to isolate a problem Focus on physical, data link and network layers to isolate a problem Focus on transport and application layers to isolate a problem Answer: B Explanation: I use the previous example as well here You must focus on specific elements or you will never isolate the problem (s) http://www.cisco.com/en/US/products/hw/routers/ps352/products_installation_and_configuration_guide_chapte r09186a008007e1d1.html#21487 QUESTION NO: Match the correct stage to its description for the process of creating network documentation Leading the way in IT testing and certification tools, www.testking.com -4- 642 - 831 Answer: Explanation: To me this only makes sense as well Login: means login no need for further info (silly description) Interface discovery: you need to find out as much about the connections as possible to construct a cogent theory of what you wish to accomplish, Document, If you have this then you are in good shape and can “see” a network diagram but for a lot of areas you must this yourself and the result will be a more thorough understanding of the issues and the processes to solve them Diagram: This applies to my previous answer in that you will need to add any new info to the current (if any) diagrams you have Device discovery: To check out any relevant devices that pertain to the issue is always a necessary step But after seeing that you have inadequate documentation you may want to proceed to get this situation together asap So this is ALWAYS a necessary step, even if you not have any issues at all this should have been done If you go to this url you will find that I am right though you will have to dig some to get it all: http://www.cisco.com/en/US/products/hw/switches/ps2246/prod_troubleshooting_guide_chapter09186a00800e a8aa.html#45390 QUESTION NO: Users report slow response time for TestKing's Intranet web server While trying to isolate the problem, you find that attempts to use ping and tracert to reach the server’s IP address are unsuccessful You are able to successfully Telnet to the server, although the response is very slow At this point, what assumptions can you make from the results of your attempts to further isolate the problem? (Choose three) A Divide and conquer troubleshooting approach should be taken B Physical layer issues have been eliminated as a possible cause of the slow response C The IP address configuration has been eliminated as a possible cause of the slow response Leading the way in IT testing and certification tools, www.testking.com -5- 642 - 831 D ICMP may be blocked by an access list somewhere on the path between the users and the Intranet web server E TCP may be blocked by an access list somewhere on the path between the users and the Intranet web server F Application layer issues have been eliminated as a possible cause of the slow response Answer: C, D, F Explanation: First off if you can telnet then you have talked via an application layer until so you not have an application layer issue Second you could not telnet without ip so this is good, at least at the device itself This would not totally explain slowdowns but we will put that aside for now Icmp could definitely be blocked as ping and tracert use this protocol To the other answers: You not know if the physical layer is good as this is a slowdown issue at least initially, so you know that there is connectivity but this does not mean there are no physical layer issues There could be lots of data being transferred at this time, a router or switch could have lost a connection (cable) and you are talking through an alternate route thus the slowdown There could be other things as well Too many to list here TCP blocked: This could not be or ther would be NO ACCESS instead of slow access to the users This is all you can know at this point without further investigation but this should be a simple issue to fix QUESTION NO: Which troubleshooting approach should be used when it is suspected that the problem is physical media or a faulty hub? A B C D Isolate and solve Top-down Bottom-up Divide and conquer Answer: C QUESTION NO: Which three stages are essential to general troubleshooting processes? (Choose three) A Research solutions Leading the way in IT testing and certification tools, www.testking.com -6- 642 - 831 B C D E Document a policy Gathering symptoms Correcting the problem Isolating the problem Answer: C, D, E QUESTION NO: What three pieces of information should you have ready before placing a call to Cisco TAC?
