Hi everyone,

I have provided a simple Word Document here, so networking experts can confirm me which questions I have answered incorrectly. I have gone to the Cisco test last week and all of a sudden this hard test comes by and I managed to score only 60+% out of 100%. Most of teh questions were outside teh scope of the new curriculum.

Here is the link to download the Word Document:


I hope that you will find some time to look over those questions and possibly point me to teh right answers or better yet write the correct answer for every question.

Many thanks in advance.

Bump :)

No takers... This is supposed to be too easy question for 500 pts.

b      They appear in the routing table when an IP address is configured on an interface.
c      They appear in the routing table when the no shut command is entered in the router interface configuration mode.  *******
d      They appear in the routing table when the show interface shows the interface is up, line protocol is up.

By default, which two factors does EIGRP use for calculating its metric? (Choose two.)
a      hop count
b      bandwidth ******
c      cost
d      delay *****
e      administrative distance

What is the purpose of a routing protocol?
a      It is used to build and maintain ARP tables.
b      It provides a method for segmenting and reassembling data packets.
c      It allows an administrator to devise an addressing scheme for the network.
d      It allows a router to share information about known networks with other routers.  ****
e      It provides a procedure for encoding and decoding data into bits for packet forwarding.

What are the three functions provided by the RIPv2 protocol? (Choose three.)
a      learning the available routes to all destinations  ****
b      providing an addressing scheme for identifying networks  ****
c      placing the best route in the routing table
d      removing routes from the routing table when they are no longer valid  ******
e      carrying user data to the destination network
f      informing LAN hosts of new default gateway addresses

At a glance:

1 -> d -> (imho, don't route to interfaces in real life)
4 -> c  (but not really)  I'd put a managed switch with a proper config to minimize broadcasts
7 -> b d (if I *have* to choose two) but really -> none of the above
9 -> b (but the route must also be in the routing table via connected, static, or null route)
10 -> a d e
15 -> b c e
17 -> d
20 -> a c d  (I don't use RIP, just going by how how routing protocols handle c)

Normally, I would say no.  But it appeared that the poster had already taken the test (and failed).

While I find it hard to believe that the tester did not provide the correct answers, I took the poster at his word.

Your call, Peter, if you believe that I need to re-think this in the future.

Hi Jesper thanks for your time. If possible can you please correct which of these questions were answered wrong from me. It took this otehr test and scored 79.2%, just 0.8 % shy of the "benchmark"..

My answers are marked with ****

Which means of communication does an SNMP network agent use to provide a network management station with important but unsolicited information?
      ICMP ping

Which benefit does SSH offer over Telnet when remotely managing a router?
      TCP usage
      connection using six VTY lines

A company wants to configure a firewall to monitor all channels of communication and allow only traffic that is part of a known connection. Which firewall configuration should be deployed?
      packet filtering ******
      stateful packet inspection
      stateless packet inspection

What is the term for the public network between the boundary router and the firewall?
      "clean" LAN
      DMZ ****

Which AAA service reduces IT operating costs by providing detailed reporting and monitoring of network user behavior, and also by keeping a record of every access connection and device configuration change across the network?
      accounting ******

A server log includes this entry: User student accessed host server ABC using Telnet yesterday for 10 minutes. What type of log entry is this?
      accounting ******

Before a technician upgrades a server, it is necessary to back up all data. Which type of backup is necessary to ensure that all data is backed up?
      full *****

A technician has configured a wireless network with WEP encryption. Several users who were able to use the wireless network are now unable to connect to the access point. What is the probable cause for the connection problem?
      WEP is a strong encryption technique that requires a successful handshake to establish connnectivity.
      The access point cannot broadcast SSIDs when WEP is enabled.
      The users have not configured their computers for WEP encryption. ******
      The access point uses 64-bit encryption, which is obsolete with newer wireless NICs.

What AAA component assigns varying levels of rights to users of network resources?
      authorization *****
      access control

Which type of authentication can be processed with or without the use of WEP keys in an 802.11 environment?
      shared key *****

Which of the following does SNMP use to hold information collected about the network?
      network management station
      network management database
      management information base ******
      database information agent

As per Peters remark, this is not actually my homework, because I need to clarify where I was wrong in those questions so when i go to the test again, I have an idea where do I need to focus more, to similar (not same) questions.

Once again I thanks you for your time and I look forward to reply.

Incorrect answers:

1. trap
3. stateful packet inspection

#10 says "with or without keys" so I'd have to think the answer was 'selective' (i.e., radius)

Thanks Jesper,
I will take a look and come back with the score. IN meantime I figured it too that trap is the correct answer for the first question. I will be looking for the rest tonight..

Hello Jesper,
I went to my test last night and  you were right about questions 1 and 3 while teh question 10 has "open" as teh right answer.

I really appreciate your time, and I hope these 500 pts serve your reputation well.

My best regards,
