Question 1

Many network hubs incorporate repeaters or amplifiers to regenerate signals so that attenuation of the signal does not occur.

Accepted Answer

This statement is true. Network hubs often have repeaters or amplifiers built in to prevent signal attenuation over long distances within the network.

Question 2

The NOS software for the server computer provides the physical,data link,and network layer functions.

Accepted Answer

NOS (Network Operating System) software primarily focuses on providing network layer functions such as network resource management, security, and file services. The physical and data link layer functions are typically handled by the hardware and its drivers, not the NOS.

Question 3

The Network Interface Card (NIC)permits a computer to be physically connected to a network's cable,which provides the network layer connection among the computers in the network.

Accepted Answer

False

Question 4

As discussed in this textbook,three layers of a network model are the components required for a typical network,including local area networks.

Accepted Answer

The answer of As discussed in this textbook,three layers of...

Question 5

LDAP is an industry standard directory protocol.

Accepted Answer

LDAP stands for Lightweight Directory Access Protocol, and it is widely used in various industries as a standard protocol for accessing and maintaining directory information services.

Question 6

Software Publishers Association has embarked upon an aggressive software audit program to check the number of illegal software copies on LANs.

Accepted Answer

The statement says that the Software Publishers Association has started an aggressive software audit program to check for illegal software copies on LANs, so the answer is A, true.

Question 7

By offloading printing tasks from the main LAN server,a print server increases network efficiency.

Accepted Answer

By offloading printing tasks to a dedicated print server, the main LAN server is able to focus on other tasks, resulting in increased network efficiency. This is because print jobs are processed and managed by the print server, reducing the burden on the main server and freeing up network resources.

Question 8

Network profile refers to what resources on each server are available on the network for use by other computers and which devices or people are allowed access on the network.

Accepted Answer

Network profile is the description of the available resources on a network and the associated access controls.

Question 9

Fiber optic cable is thicker and heavier than unshielded twisted pair.

Accepted Answer

Fiber optic cable is actually much thinner and lighter than unshielded twisted pair. It consists of a thin strand of glass or plastic that carries light signals, whereas UTP is made up of multiple copper wires twisted together.

Question 10

Resource sharing refers to having users access the same data files,exchange information via e-mail,or use the Internet.

Accepted Answer

The answer of Resource sharing refers to having users access...

Question 11

Traditional Ethernet is also known as shared Ethernet.

Accepted Answer

Traditional Ethernet uses a shared medium for communication and is therefore also known as shared Ethernet.

Question 12

LAN metering software can be used to prohibit using more copies of a package than there are installed licenses.

Accepted Answer

LAN metering software is designed to monitor and control the usage of software licenses within a network. It can detect when there are more copies of a package being used than there are installed licenses and can prohibit further usage until additional licenses are obtained.

Question 13

A hardware device that is not included in a network profile cannot be accessed by another computer on the network.

Accepted Answer

If a hardware device is not included in a network profile, other computers on the network will not be aware of its existence and therefore cannot access it.

Question 14

Peer-to-peer networks have computers that are permanently assigned as network servers

Accepted Answer

Peer-to-peer networks do not have computers that are permanently assigned as network servers. Instead, each node in the network acts as both a client and a server, sharing resources and files with other nodes.

Question 15

One of the most important functions of Network Operating System (NOS)is a directory service.

Accepted Answer

This is true as a directory service is a key component of a NOS, providing centralized management of resources and user accounts within a network environment. It allows users to easily access and locate resources such as files, printers and servers within the network. Examples of directory services include Microsoft Active Directory and Novell eDirectory.

Question 16

A Network Operating System (NOS),such as Linux or Windows Server 2008,must be used in addition to the 'normal' operating system,such as Windows,on a server in a dedicated server LAN.

Accepted Answer

The answer of A Network Operating System (NOS),such as Linux...

Question 17

LANs that run on radio frequencies use a type of wired media.

Accepted Answer

LANs that run on radio frequencies use wireless media, not wired media.

Question 18

Ethernet is a layer 3 protocol,which operates at the network layer.

Accepted Answer

Ethernet is a layer 2 protocol that operates at the data link layer. It provides the means to transmit data frames between devices connected to the same physical network. Layer 3 protocols, such as IP, operate at the network layer and facilitate communication between different networks.

Question 19

LANs can be categorized as either dedicated (with a dedicated server)or peer-to-peer (without a dedicated server).

Accepted Answer

This statement is true. LANs can indeed be categorized as either dedicated or peer-to-peer networks depending upon whether they have a dedicated server or not.

Question 20

On a network,it is always legal to purchase one copy of software,such as a word processing package,that multiple users use simultaneously.

Accepted Answer

It is illegal to purchase one copy of software and use it simultaneously on multiple computers or by multiple users. Each user or computer needs their own licensed copy of the software.
