Top Five Questions and Answers

Top Five Questions and Answers

1. Differentiate User Mode from Privileged Mode
A. User Mode is used for regular task when using a CISCO router, such as to view system information, connecting to remote devices, and checking the status of the router. On the other hand, privileged mode includes all options that are available for User Mode, plus more. You can use this mode in order to make configurations on the router, including making tests and debugging.
2. What is 100BaseFX?
A. This is Ethernet that makes use of fiber optic cable as the main transmission medium. The 100 stands for 100Mbps, which is the data speed.
3. Differentiate full-duplex from half-duplex.
A. In full-duplex, both the transmitting device and the receiving device can communicate simultaneously, that is, both can be transmitting and receiving at the same time. In the case of half-duplex, a device cannot receive while it is transmitting, and vice versa.
4. What is MTU?
A. MTU stands for Maximum Transmission Unit. It refers to the maximum packet size that can be sent out onto the data line without the need to fragment it.
5. What is latency?
A. Latency is the amount of time delay that measures the point from which a network device receives a data frame to the time it sends it out again towards another network segment.

What causes CRC errors?

What causes CRC errors?

A. Cisco networking CRC errors are generally a layer 1 issue caused by a faulty port on the device or bad Ethernet cable. Changing the cable or swapping the port is a relatively easy fix. Occasionally they are generated on layer 2 by a duplex mismatch. This happens when the port on one device is set for full-duplex and the port on the connected peer device is set for half-duplex.
The ports can be compared by using the show interface command on both devices.
In TDM networks, there are many problems that cause CRC errors. They include faulty wiring or cross-connects, bad repeater cards, flakey smart jacks, or bad cable and channel cards. Isolating the cause of these errors usually requires the telecommunications provider to conduct loopback testing or to dispatch a field engineer to the site to test head-to-head with the central office.
