Cisco Connection Online (CCO) includes. What would
your reply be? (Select the best option.)
A. Cisco Technical Information Centre (TIC) web site
B. Cisco Technical Assistance Centre (TAC) web site.
C. Cisco Centre for Aid in Troubleshooting (CAT) web site.
D. Cisco Internetworking Troubleshooting Centre (ITC) web site.
Answer: B
Explanation: Cisco Technical
Assistance Centre is also the name of the Cisco technical
assistance web site. To verify you may visit the site.
See http://www.cisco.com/en/US/support/index.html
QUESTION 2 You are the network administrator at Cisco Sources .com. You encountered
a complex problem on the Cisco Sources server that necessitates
troubleshooting. Which approach should you use?
A. Top-down
B. Bottom-up
C. Top-to-Bottom
D. Divide-and-conquer
E. Split-difference
Answer: B
Explanation: This is the Cisco
recommended technique for troubleshooting any type
of problem. It is the most time efficient way to get
to the root of the problem. If you go to the site
you mentioned below, 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 from the bottom up. Example: http://www.cisco.com/en/US/products/hw/routers/ps352/products_installation_and_configuration_
guide_chapte r09186a008007e1d1.php#21487
QUESTION 3 You are a PC technician at Cisco Sources . Your newly appointed Cisco Sources
trainee wants to know what a logical layered network
model enables you to do. What would your reply be?
A. Focus on physical, data link and network layers to isolate a problem.
B. Focus on specific elements to isolate a problem.
C. Focus on physical layers to isolate a problem
D. Focus on transport and application layers to isolate a problem.
Answer: B
Explanation: Working
from the bottom-up, you should focus on specific elements
or you will never be able to isolate the problem (s). http://www.cisco.com/en/US/products/hw/routers/ps352/products_installation_and_

QUESTION 4 There is a certain procedure that has to be followed when creating network
documentation. Match the correct stage to its description.
Answer: Explanation: To create network documentation the following steps are necessary:
- Login: to gain access to any undocumented
neighbouring device.
- Interface discovery: once
logged in, you can determine the connections to
the network to enable you to construct a cogent
theory
- 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 do this
yourself and the result will be a more thorough
understanding of the issues and the processes to
solve them.
- Diagram: When focussing
on new elements you will need to add any new info
to the current (if any) diagrams you have.
- Device discovery:
This applies to my previous answer in that 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 do not have any issues at all this should have
been done. For further information consult this
url mentioned below you will find that you will
have to dig some to get it all: http://www.cisco.com/en/US/products/hw/switches/ps2246/prod_troubleshooting_guide_

QUESTION 5 You are the network administrator at Cisco Sources .com. Several Cisco Sources
users lodged complaints of slow response time for
Cisco Sources 's Intranet web server. You address the
issue by isolating the problem and find that when
trying to use ping and tracert, you cannot reach the
server's IP address. You are however able to Telnet
the server, albeit slow. At this point, what assumptions
regarding your attempts to further isolate the problem,
can you make. (Choose all that apply.)
A. TCP may be blocked by an access list somewhere on the path between the
users and the Intranet web server.
B. Physical layer issues have been eliminated as a possible cause of the
slow response.
C. Application layer issues have been eliminated as a possible cause of the
slow response.
D. The IP address configuration has been eliminated as a possible cause of
the slow response.
E. Divide and conquer troubleshooting approach should be taken.
F. ICMP may be blocked by an access list somewhere on the path between the
users and the Intranet web server.
Answer: C, D, F
Explanation: Firstly, if you
can telnet then you communicated via an application
layer hence you do 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 do 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 there 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 6 You are a PC technician at Cisco Sources . You are troubleshooting a network
connectivity problem. You suspect that the problem is physical media, or a faulty hub. Which troubleshooting approach should
you take?
A. Top-down
B. Divide and conquer
C. Bottom-up
D. Isolate and solve
E. Random
Answer: C
Explanation: These problems are related to the physical layer (Layer 1) of the OSI reference
model. This layer is located at the bottom of the OSI model.
QUESTION 7 You are a PC technician at Cisco Sources . Your newly appointed Cisco Sources
trainee wants to know which three stages are essential
in a general troubleshooting process. What would your
reply be? (Choose all that apply.)
A. Document a policy
B. Research solutions
C. Gathering symptoms
D. Isolating the problem
E. Correcting the problem
Answer: C, D, E
Explanation: In any case
where troubleshooting is needed, it is necessary and
logical to first Gather the symptoms, To isolate the problem and To correct the problem. Documenting a policy assumes no troubleshooting necessary.
QUESTION 8 You are a junior MCP technician Cisco Sources . The CCNP technician is currently
on leave in Dubai. You encounter a problem on the
network. The problem is related to a Cisco device.
You want to know place a call to Cisco TAC for advice.
What three pieces of information should you acquire
before placing the call? (Choose all that apply.)
A. Packet traces
B. Switch error logs
C. Client patch levels
D. Trace Server event logs
E. Recent configuration changes
Answer: A, B, E
Explanation: When you contact the Cisco TAC, it is necessary to have the Packet traces,
Switch error logs and Recent configuration changes at hand as it would expedite a good, effective response
from TAC.
