Question 1

The difference between (EIA/TIA) 568A and 568B wiring standards is the positioning of pairs 2 and 3 .

Accepted Answer

The EIA/TIA 568A and 568B wiring standards differ in the positioning of pairs 2 and 3, specifically in the way that they are crossed or not crossed over. Pair 2 is typically orange, and pair 3 is typically green. In 568A, pair 2 is crossed over, meaning that the orange wire is connected to the green wire on the opposite end, and vice versa. In 568B, pair 2 is not crossed over, and both the orange and green wires are connected straight through to the corresponding pins on the opposite end. The difference in wiring standards affects which colors are used for which pins and can impact the compatibility of different devices and networking equipment.

Question 2

A privately owned network of interconnected data communicating devices that share resources within a small geographical area is a ___________&#10;A) WAN&#10;B) LAN&#10;C) MAN&#10;D) CAN

Accepted Answer

LAN stands for Local Area Network which is a privately owned network that operates within a small geographical area such as an office, building or group of buildings. It allows the devices to communicate with each other and share resources such as printers and internet connection. WAN (Wide Area Network) covers a large geographical area mostly provided by ISPs, MAN (Metropolitan Area Network) serves a city or a town and CAN (Campus Area Network) covers a university or a college campus.

Question 3

What is the purpose of using carrier sense multiple access with collision detection (CSMA/CD)?&#10;A) To allow multiple computers to talk simultaneously using one line&#10;B) To prevent multiple transmissions on a line&#10;C) To provide fast transmissions speeds&#10;D) All the above

Accepted Answer

The purpose of using CSMA/CD is to prevent multiple transmissions on a line by ensuring that a device checks for a free channel before transmitting. This helps to avoid collisions and improve the overall efficiency of the network. Option A is incorrect as CSMA/CD does not allow multiple computers to talk simultaneously on one line. Option C is also incorrect as the speed of transmission is not specifically related to the use of CSMA/CD. Option D is incorrect as only option B is a correct statement.

Question 4

The network topology that consists of a central connecting device with branches going off to each workstation is called a ________ topology.&#10;A) Star&#10;B) Ring&#10;C) Bus&#10;D) Token

Accepted Answer

The star network topology has a central connecting device (such as a switch or hub) that connects to each workstation, resembling the shape of a star. This central device is responsible for managing and directing traffic. Therefore, the star topology fits the description given in the question.

Question 5

A set of rules that govern the manner in which data is both transmitted and received is called a __________.&#10;A) Packet&#10;B) Topology&#10;C) Transmission&#10;D) Protocol

Accepted Answer

A set of rules that govern the manner in which data is both transmitted and received is called a protocol. Options A, B, and C are not the correct terms to define this concept.

Question 6

What type of networking equipment would be used to get a TCP/IP network talking to a IPX/SPX network ?&#10;A) A Firewall&#10;B) A LAN Extender&#10;C) A Gateway&#10;D) A Bridge

Accepted Answer

A Gateway is used to connect networks that use different protocols. In this case, a TCP/IP network and an IPX/SPX network use different protocols and a gateway would be needed to facilitate communication between the two.

Question 7

From which layer of the OSI model does Transfer Control Protocol (TCP) operate?&#10;A) The physical layer&#10;B) The frame layer&#10;C) The transport layer&#10;D) The application/process layer

Accepted Answer

TCP operates at the transport layer of the OSI model, which is responsible for reliable data transfer between applications. It provides features such as error checking, flow control, and congestion control.

Question 8

The manner in which multiple computers are physically connected together is called________.&#10;A) Network Protocol&#10;B) Network Topology&#10;C) A LAN&#10;D) Network Addressing

Accepted Answer

Network Topology refers to the physical or logical layout of a network. It describes how devices and computers are connected to each other and how they communicate with each other. Network Protocol refers to a set of rules and standards that devices on a network use to communicate with each other. A LAN (Local Area Network) refers to a network that covers a relatively small geographical area, such as a home, office, or building. Network Addressing refers to the way in which devices on a network are identified and addressed. Therefore, the best choice is B - Network Topology.

Question 9

Category 3 (CAT-3) cable can support data transmission at speed up to 16Mbps.

Accepted Answer

CAT-3 cable can support data transmission at speeds up to 10Mbps, not 16Mbps.

Question 10

In asymmetrical DSL connections, uploads from a computer will be slower than downloads.

Accepted Answer

Asymmetrical DSL connections are designed to provide faster download speeds than upload speeds. Therefore, uploads from a computer will be slower than downloads in such connections.
