Cisco 1 Chapter 2 Exam

What is the maximum distance of 100BaseTX?

100 meters

What is the maximum distance of 10BaseT?

100 meters

Fast Ethernet is defined under the IEEE ____ standard.

802.3u

Ethernet contention method

CSMA/CD

Ethernet uses ____ to prevent data packets from colliding on the network.

CSMA/CD

Stations on a network ____ packets to other stations to make their presence known on the network and to carry out normal network tasks such as IP address-to-MAC address resolution.

Broadcast

A group of network devices that will receive LAN broadcast traffic from each other

Broadcast domain

A frame destined for all computers on the network.

Broadcast frame

A sudden rush of network transmissions that causes all other network communications to slow down due to the volume of data competing for access to the same bandwidth on the communications medium

Broadcast storm

Degradation of signal clarity.

Attenuation

Segments a network by filtering traffic at the Data Link layer

Bridge

The ____ is information that is used to determine whether data was corrupted during transmission.

CRC

Select the three layers in the Cisco hierarchical model. (Select three) Core Access Network Interface Transport Distribution Network

Core Access Distribution

Which type of cable should be used when connecting between Cisco switches?

Crossover

Repeaters and hubs reformat data structures, so they can connect networks that require different types of frames.

False

When a segment has too much broadcast traffic, utilization increases and network performance in general benefits.

False

____ Ethernet uses the same network access method (CSMA/CD) as common 10BaseT Ethernet, but provides 10 times the data transmission rate.

Fast

You want to implement a network medium that is not susceptible to EMI. What type of cabling should you use?

Fiber-optic

In ____ communications, devices can send and receive signals, but not at the same time.

Half-duplex

A generic connection device used to tie several networking cables together to create a link between different stations on a network

Hub

How does a host on an Ethernet network know when to resume transmissions after a collision has occurred?

The hosts will attempt to resume transmission after a time delay has expired

The length of time that is required to forward, send, or otherwise propagate a data frame

Latency

A(n) ____ address is a 48-bit address represented as a 12-digit hexadecimal number given to each network card during production.

MAC

Switches filter based on ____ addresses.

MAC

Preventing communications between just two computers from being broadcast to every computer on the network or segment

Microsegmentation

A bridge maintains a ____ that maps the MAC addresses on each segment to the corresponding port on the bridge to which each segment is connected.

Multicast table

Each layer in a protocol stack may add a(n) ____ to the data as it is passed down the layers.

PDU

The OSI model ____ layer defines the mechanical, electrical, and procedural events that occur during the physical transmission of electronic signals on the wire.

Physical

The term ____ refers to a series of storage devices, such as tapes, hard drives, and CDs, that are networked together to provide very fast data storage for a network or subnetwork.

SAN

A part of a network that is divided logically or physically from the rest of the network

Segment

What are the benefits of using full-duplex? (Select 3) Time is not wasted retransmitting frames, because there are no collisions. While there are still collisions, there are fewer collisions than in a half-duplex network The full bandwidth is available in both directions because the send and receive functions are separate. Stations do not have to wait until other stations complete their transmissions. Stations will wait a short amount of time until other stations complete their transmissions.

Time is not wasted retransmitting frames, because there are no collisions. The full bandwidth is available in both directions because the send and receive functions are separate. Stations do not have to wait until other stations complete their transmissions.

The main difference between a switch and a bridge is that the switch typically connects multiple stations individually, thereby segmenting a LAN into multiple collision domains.

True

The number of nodes on a network and the length of cable used influence the quality of communication on the network.

True

In an Ethernet network, under what two scenarios can devices transmit? (Choose two) When they receive a special token When there is a carrier When they detect no other devices are sending When the medium is idle When the server grants access

When they detect no other devices are sending When the medium is idle
