Question 7

What is one way to help safeguard a wireless network?
A)connect to the router and change the default logon and password
B)enable service set identifier broadcasting
C)configure the security to WEP
D)disable the admin access

Accepted Answer

Changing the default logon and password for the router can help prevent unauthorized access to the network. It is important to choose a strong password that is not easily guessable. Enabling SSID broadcasting and configuring security to WEP are not recommended as they offer limited protection and can be easily hacked. Disabling admin access can also limit the ability to manage and troubleshoot the network.

Question 8

A half-duplex channel can transmit data in either direction, but not simultaneously.

Accepted Answer

In a half-duplex channel, data can be transmitted in both directions, but only one direction at a time. This means that data cannot be transmitted simultaneously in both directions.

Question 9

A networking protocol is a set of rules, algorithms, messages, and other mechanisms that enables software and hardware in networked devices to communicate effectively.

Accepted Answer

This statement is correct. A networking protocol is a set of rules that governs the communication between network devices, such as computers, routers, switches, and servers, and enables them to exchange data and information in a standardized and efficient way. These protocols define the format and sequence of messages, the addressing and routing schemes, the error detection and correction mechanisms, and other aspects of the communication process, so that devices from different vendors and with different capabilities can interoperate and exchange data seamlessly. Examples of networking protocols include TCP/IP, HTTP, FTP, DNS, SNMP, SMTP, and many others.

Question 10

How many GPS satellites are used to determine the accurate position of a GPS receiver?
A)three
B)four
C)five
D)six

Accepted Answer

The accurate position of a GPS receiver is determined by receiving signals from at least four GPS satellites. Three satellites can provide a rough estimate of the position but cannot determine elevation or altitude. Four satellites are needed to determine three-dimensional position and the time offset between the receiver and the satellites.

Question 11

Alex must protect his research data when it is sent abroad for review.What measures will he use to protect his data?
A)encryption
B)a virtual private network
C)a dedicated network service
D)a personal area bridge

Accepted Answer

The answer of Alex must protect his research data when...

Question 12

Kbps stands for thousands of bytes per second.

Accepted Answer

Kbps stands for kilobits per second, not kilobytes per second.

Question 13

What does an asymmetric DSL provide?
A)high-speed Internet access over a subscribers cable network
B)an additional phone line to receive "always on" Internet access
C)a dedicated connection from each user to the phone company's local telephone office
D)a level of service that is independent of how far the subscriber is from the local telephone office

Accepted Answer

Asymmetric DSL (ADSL) provides a dedicated connection from each user to the phone company's local telephone office, allowing for high-speed Internet access over existing telephone lines.

Question 14

Accepted Answer

The answer of At Athabasca University in Alberta, distance learning...

Question 15

What does a VPN provide to users?
A)a personalized password
B)a personal network at home
C)access to an organization's public network
D)a token that displays a constantly changing password

Accepted Answer

A VPN provides a secure, encrypted connection over a public network, allowing users to access private networks and resources remotely.

Question 16

The CRTC created a registry to deal with solicitation.What is the name given to this registry?
A)National Do Not Call Registry
B)National Do Not Disturb Registry
C)National Call Centre Access Registry
D)National Automatic Call Centre Registry

Accepted Answer

The National Do Not Call Registry was created by the Canadian Radio-television and Telecommunications Commission (CRTC) to address the issue of unwanted telemarketing calls. This registry is designed to allow Canadians to opt out of receiving telemarketing calls by adding their home or mobile phone numbers to the list. Once a number is on this list, telemarketers are prohibited from calling that number unless they have received consent from the individual.

Question 17

What can a network manager do with network-management software?

Question 18

What is a common aspect of a multiplexer?
A)It is used on local phone calls
B)It can greatly increase telecommunications costs
C)It greatly affects the speed and quality of an individual call
D)It combines data from multiple sources into a single output signal that carries multiple channels

Accepted Answer

A multiplexer is a device that combines data from multiple sources into a single output signal that carries multiple channels. This is done by dividing the high-speed digital transmission medium (such as fiber optics) into multiple channels or time slots and assigning each channel to a particular user or data stream. This allows multiple users to share a single communication line, which can save costs and increase efficiency.

Question 19

Ali is looking at how to manage office space since he has many more consultants than offices for each one of them.The consultants are equipped with laptops and can work practically everywhere where they can access the Internet.What can he implement that would work?
A)videoconference
B)electronic data interchange
C)shift work schedules
D)telecommuting

Accepted Answer

Telecommuting would work best for managing office space when there are more consultants than available offices. With telecommuting, consultants can work from their own homes or remote locations, which reduces the need for office space. This also allows for more flexibility in work schedules and can increase productivity. Videoconferencing and electronic data interchange may assist in communication and collaboration but they do not address the issue of limited office space. Shift work schedules can help optimize the use of existing office space, but may not be the most practical or efficient solution in this scenario.

Question 20

What two operating systems are NOT commonly used on smartphones?
A)Symbian and Palm OS
B)iPhone OS and RIM OS
C)HP UX and z/OS
D)Android and Microsoft Windows Mobile

Accepted Answer

HP UX and z/OS are primarily used on mainframe and server systems, and are not commonly used on smartphones. Symbian and Palm OS were once commonly used on smartphones but have been largely replaced by newer operating systems. iPhone OS (now known as iOS) and RIM OS (now known as BlackBerry OS) were previously popular on smartphones, but their market share has decreased in recent years. Android and Microsoft Windows Mobile are currently popular operating systems for smartphones.
