You can Google for this information, but I don't recommend using a braindump site; the answers are very often incorrect, since it is based on the memory recollection of someone who took the exam, and the answers have not been checked for accuracy.

Furthermore, the use of such material goes against the user agreement that you sign when you sit for an exam.

Fiber Optic connectors are normally either SC or ST SC is the accepted standard.

UTP or unshielded twisted pair cabling is used in local area networks. Two causes of signal degradation are losing light over long distances and low quality cable shielding.

On user exec mode type enable.

When inside the privilege mode type configure terminal. You will then be sitting into global config after this.

Please see below example:

Router>enable

Router#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#

There are three different ways. The first one is by voice over ip. The second way is by using a voice over ip service and the third way is by using landline telephones with a analog telephone adapter connected to your network.

By networking multiple pcs, or macs you can share files easily, Edit other files on other computers without the need to put it on an external drive or USB flash drive. You also don't need to have multiple copies of item/s on each computer, photos, songs, movies can be stored on the one and shared throughout. You can also share a dial-up and broadband internet connection.

well, a firewall could do it, but an Intrusion Prevention System is the more obvious answer.

Well what sort of application is the 2600 router going to be used in? Here is a short thing about setting the clock http://www.learnios.com/viewtopic.php?f=4&t=36 Here a little more on setting up interfaces http://www.learnios.com/viewtopic.php?f=72&t=34 Here is password recovery steps http://www.learnios.com/viewtopic.php?f=4&t=28 Setting up cisco routers can be done many ways if you are looking for and more direct answer I suggest asking a more direct question like "how do I setup DCHP on my 2600" or how do I ip interfaces

The idea is to send a message to several recipients at once. On the backbone of the network, a message might be sent only once; later, when the paths to the recipients separate, several copies are made. This can help save bandwidth of the Internet backbone (or other, smaller, networks), in certain circumstances. Multicasting is especially useful if the same information is to be sent to all recipients at the same time. A typical case might be a live radio or television broadcast over the Internet.

If there is a congestion in one direction, the FECN (forward explicit congestion notification) bit is set to inform routers in the forward direction (from the point of view of the traffic) about the congestion. Also, eventually some frames will travel back to the origin; in that case, the BECN (backword explicit congestion notification) bit is also set to inform the origin about the congestion.

This document summarizes the cabling requirements for console and auxiliary (AUX) ports. Cisco routers either have RJ-45-based or DB-25 DCE/DTE console and AUX ports. You can connect either a terminal (DTE) or a modem (DCE) to these ports. In either instance, you need both an RJ-45 cable and an RJ-45-to-DB-25 or RJ-45-to-DB-9 connector.

Routing Information Protocol (RIP) and Interior Gateway Routing Protocol (IGRP) are two very popular Distance Vector routing protocols

The command "show vtp status" will show you how many vlans are supported by the switch. The Cisco 2950 switch supports up to 64 VLANs.

The Cisco 2621XM is a Modular Access Router that you can use to access the internet, both wired and wirelessly. Wireless internet is becoming more popular as more people switch to using laptops rather than desktop computers.

1. straigth cable are more effective than the crossover cable....

It is the privilege mode.

1. Its a rollover cable. 2. I'm not doing all your cisco questions. 1. Its a rollover cable. 2. I'm not doing all your cisco questions.

First, get yourself a serial cable and access to the console port. When you have that arranged, try to get (unprivileged will do) access to the router's prompt and run a show versioncommand. Record the value of the configuration register. If you can't login, you can assume it's 0x2102.

Next, powercycle the router. Within 60 seconds of power on, send a BREAK key down the serial console to put the router into ROMMON mode, which stops it booting IOS.

At the prompt rommon 1> type confreg 0x2142 to instruct the router to boot from flash, but not load the startup-config. Type reset next.

After the router is restarted it'll ask to go into setup mode, don't do that.

Type enable or en.

Type copy start run.

Type show run . You will see some passwords unencrypted, which you can simply write down. The enable secret, if used, will be encrypted and must be reset.

Type conf t .

Type enable secret to reset the enable secret to your new password.

Issue a no shut for each interface you use.

Type config-register 0x2102 (or the value you wrote down earlier)

Type end .

Type copy run start to save your changes.
