Question 1

You are building a gaming computer and you want to install a dedicated graphics card that has a fast GPU and 4GB of memory on board. You need to make sure that you have the right connector available on your motherboard. What type of connector would be appropriate?
A) PCI
B) SATA
C) PCI Express
D) IDE

Accepted Answer

The appropriate connector for a dedicated graphics card with a fast GPU and 4GB of memory on board is PCI Express. SATA and IDE connectors are used to connect storage devices like hard drives and SSDs, while the PCI connector is an older standard that is not commonly used for graphics cards anymore.

Question 2

The XYZ company has two offices, one in Chicago, and a brand new office in Pittsburgh. To connect the two offices, they will need a dedicated line, probably leased from the phone company. What type of network will they be implementing to connect their two offices?
A) LAN
B) WAN
C) PAN
D) SAN

Accepted Answer

The type of network that the XYZ company will be implementing to connect their two offices is a WAN (Wide Area Network). WANs are used to connect multiple locations that are separated by a large distance. In this case, the Chicago and Pittsburgh offices are separated by a considerable distance, so a WAN would be the most appropriate type of network to use. A LAN (Local Area Network) is used to connect devices within a small geographic area, such as a single office building. A PAN (Personal Area Network) is used to connect devices that are within a person's immediate vicinity, such as a smartphone and a smartwatch. A SAN (Storage Area Network) is used to connect servers to storage devices. None of these types of networks would be appropriate for connecting the Chicago and Pittsburgh offices.

Question 3

When data is being prepared for transmission onto the network, it is broken into small pieces and a header and trailer are added to each piece to help identify it. What is this process called?
A) multitasking
B) verification
C) encapsulation
D) application

Accepted Answer

This process is called encapsulation. Encapsulation involves adding a header and trailer to each piece of data to help identify it and ensure it is transmitted properly over the network. It is a necessary step in the transmission of data over the network.

Question 4

Which part of the network communication process is responsible for sending and receiving data to and from the network media?
A) network software
B) network protocol
C) user application
D) network interface

Accepted Answer

The network interface is responsible for sending and receiving data to and from the network media. It is the physical connection between the computer and the network and handles the conversion of data between digital signals used by computers and analog signals used by the network media. The other choices play a role in the network communication process but are not directly responsible for sending and receiving data to and from the network media.

Question 5

Air waves are an example of what type of network component?
A) network interface card
B) network medium
C) interconnecting device
D) network protocol

Accepted Answer

Air waves are a type of network medium, which refers to the physical means through which data travels in a network. Examples of other network mediums include cables, wireless signals, and fiber optics. A network interface card (NIC) refers to the hardware component that allows a device to connect to a network, while an interconnecting device refers to hardware such as routers, switches, and hubs that allow multiple devices to connect and communicate within a network. Network protocols refer to the rules and standards that govern how data is transmitted and received in a network.

Question 6

Each component of a computer is designed to perform only one specific task-either input, processing, or output.

Accepted Answer

While each component is primarily responsible for one of the three tasks, most components also perform some level of additional functionality beyond their primary task. For example, a CPU may also have some memory management capabilities, and an input device like a keyboard may also have some basic processing capabilities for handling key-press timing and basic input validation.

Question 7

What makes a computer a "server" is the fact that it has a server operating system installed on it.

Accepted Answer

A server is a computer or program that provides a service to other computers or programs on a network. What makes a computer a server is the software installed on it, specifically a server operating system, which is designed to manage and respond to multiple requests from clients or other computers seeking a service or resource.

Question 8

Using the physical mail analogy, what part of an address on an envelope is most like the IP address?
A) MAC address
B) street address
C) recipient name
D) zip code

Accepted Answer

The answer of Using the physical mail analogy, what part...

Question 9

Which component manages the details of communicating with the NIC hardware to send and receive data to and from network media?
A) client
B) server software
C) network protocol
D) device driver

Accepted Answer

The device driver is responsible for managing the communication between the computer's operating system and the network interface card (NIC) hardware. It allows the computer to send and receive data to and from the network media. The client, server software, and network protocol do not directly manage the communication with the NIC hardware.

Question 10

Every NIC has a unique address that consists of a 12-digit hexadecimal value. What is this address called?
A) IP address
B) subnet mask
C) MAC address
D) default gateway

Accepted Answer

The unique address that consists of a 12-digit hexadecimal value is called a MAC address. A MAC address stands for Media Access Control address and is assigned to a NIC (Network Interface Card) to uniquely identify it on a network. IP address, subnet mask, and default gateway are also important components of networking but do not refer to the unique identifier of a NIC.

Question 11

In order to find out your MAC address, you should open a command prompt and type ipconfig /all.

Accepted Answer

Running the command "ipconfig /all" in the command prompt will display network information for your device, including the MAC address.

Question 12

What is one of the disadvantages of a peer-to-peer network compared to a server-based network?
A) more difficult to setup and install
B) more expensive
C) higher administration costs
D) limited security

Accepted Answer

One of the key disadvantages of a peer-to-peer network is limited security. In a peer-to-peer network, each device is responsible for managing its own security, which can lead to vulnerabilities and potential security breaches. In contrast, a server-based network allows for more centralization and control over security measures.

Question 13

An extranet is a private network, such as a school or company network, in which the devices and servers are available only to users connected to the internal network.

Accepted Answer

An extranet is a controlled private network that allows access to partners, vendors, and suppliers or an authorized set of users outside the company, extending beyond the company’s internal network, unlike an intranet which is restricted to internal users only.

Question 14

A network that connects LANs in different countries is most likely a WAN.

Accepted Answer

A WAN (Wide Area Network) is a network that connects LANs (Local Area Networks) that are geographically separated, such as LANs in different countries.

Question 15

Windows 10 is an example of which of the following?
A) network protocol
B) client operating system
C) server software
D) server operating system

Accepted Answer

Windows 10 is a client operating system designed for personal computers and devices. It is not a network protocol, server software, or server operating system.

Question 16

What is one of the disadvantages of a server-based network compared to a peer-to-peer network?
A) additional costs
B) decentralized data access
C) difficult to expand
D) less secure

Accepted Answer

Server-based networks involve additional costs due to the need for dedicated server hardware and potentially more complex software and maintenance, unlike peer-to-peer networks where each computer can act as both a server and a client, reducing the need for specialized hardware.

Question 17

You are the network administrator for a company and you want to separate the traffic from the accounting department from the rest of the network. However, the accounting department still needs to have access to other network resources. What type of network do you need to implement?
A) WPAN
B) internetwork
C) WAN
D) wireless network

Accepted Answer

An internetwork or VLAN (Virtual Local Area Network) can be implemented to separate the traffic from the accounting department while still allowing them access to other network resources. This can be achieved through the use of a switch with VLAN capability or by configuring a software-based VLAN. A WPAN (Wireless Personal Area Network) or wireless network would not be ideal in this scenario as it does not provide the necessary segregation of traffic, while a WAN (Wide Area Network) is designed for connecting geographically separated networks and is not appropriate for local traffic management.

Question 18

Which component, located on the motherboard, carries out all the instructions provided by computer programs?
A) hard drive
B) RAM
C) NIC
D) CPU

Accepted Answer

The CPU (Central Processing Unit) is the component that carries out all the instructions provided by computer programs. The hard drive stores data and programs, RAM temporarily stores data and programs for the CPU to use, and the NIC (Network Interface Card) enables the computer to connect to a network. However, none of these components carry out instructions provided by computer programs like the CPU does.

Question 19

You want a fast CPU for the new computer you are building and your motherboard only has one CPU socket. To increase the processing power, you need a CPU that provides more than one processor. What type of CPU are you looking for?
A) multicore
B) multiprocessing
C) multitasking
D) multilink

Accepted Answer

A multicore CPU would provide multiple processors within a single CPU, which would give the desired increase in processing power on a motherboard with only one CPU socket. The other options (B, C, and D) do not refer specifically to multiple processors within a single CPU.

Question 20

What command would you issue from a command prompt to see a listing of the computers in your workgroup?
A) arp -a
B) net view
C) ipconfig /all
D) ping

Accepted Answer

The "net view" command shows a list of computers in the local workgroup or domain.
