Question 1

________ networks are an emerging technology that is becoming increasingly important to help organizations manage their data flows across their enterprise networks.

Accepted Answer

Software-defined networks use centralized software to manage network traffic and allow for more efficient and flexible management of data flows across enterprise networks. This technology is becoming increasingly important as organizations deal with large volumes of data and the need for more dynamic network configuration.

Question 2

A network that is restricted to a single building is a ________.

Accepted Answer

A LAN (Local Area Network) is a type of network that is limited to a small geographic area, such as a building or a campus. It is typically owned and operated by a single organization, and can be used to provide connectivity to computers, printers, and other devices within the network. The other options (MAN, PAN, and WAN) are all broader types of networks that cover larger areas, such as a city, personal devices, or multiple buildings or even countries.

Question 3

________ is the world's most isolated country when it comes to telecommunications access.

Accepted Answer

Eritrea is considered the world's most isolated country when it comes to telecommunications access due to its government's strict control over its telecommunications sector and limited access to the internet and mobile networks.

Question 4

Over 200 ________ e-mail messages are sent and received each day.

Accepted Answer

Over 200 billion e-mail messages are sent and received each day globally.

Question 5

Slack partnered with ________ to utilize Watson Conversation,a software tool that helps bots interact through natural language.

Accepted Answer

IBM is the company that developed Watson Conversation, a software tool used by Slack to help bots interact with users through natural language.

Question 6

________s allow devices to physically connect to the LAN's communication's medium.

Accepted Answer

NIC stands for Network Interface Card, and it is a hardware component that allows devices to connect to a LAN's communications medium, such as an Ethernet cable or Wi-Fi antenna. Backbone refers to the main communication pathway of a network, ERP stands for Enterprise Resource Planning software used for managing business operations, and QR code is a matrix barcode used for storing and sharing information.

Question 7

A network between Mars and the Earth would be a ________.

Accepted Answer

A WAN (Wide Area Network) would be the most appropriate choice as it refers to a network spread over a large geographical area, such as between Earth and Mars. A LAN (Local Area Network) would be confined to a small area, a MAN (Metropolitan Area Network) to a city, and a PAN (Personal Area Network) to personal devices within close range.

Question 8

A network stretching across New York City would be a ________.

Accepted Answer

A network stretching across an entire city would be a Metropolitan Area Network (MAN). A Local Area Network (LAN) is typically used for a smaller area, such as a single building or office. A Personal Area Network (PAN) is used for connecting personal devices, such as a phone or computer, within a short distance. A Wide Area Network (WAN) typically spans multiple cities or even countries.

Question 9

Which of the following is the correct order of networks from smallest to largest?

Accepted Answer

PAN stands for Personal Area Network and covers a small area like a single room or device. LAN stands for Local Area Network and covers a larger physical area like a building or campus. MAN stands for Metropolitan Area Network and covers an even larger geographical area like a city or region. WAN stands for Wide Area Network and it covers the largest geographical area like a country or even the entire world. Therefore, the correct order of networks from smallest to largest is PAN, LAN, MAN, WAN.

Question 10

Ethernet is a technology associated with ________s.

Accepted Answer

Ethernet is a technology used for Local Area Networks (LANs). It provides a way for devices to communicate with each other within a limited area, such as within a building or campus. It is not commonly used for Metropolitan Area Networks (MANs), Personal Area Networks (PANs), or Wide Area Networks (WANs).

Question 11

The Internet is a ________.

Accepted Answer

The Internet is a WAN (Wide Area Network) as it connects networks across a wide geographic area, often spanning multiple cities, countries, and even continents. LAN (Local Area Network) is a network that covers a small geographical area, such as a single building or office. MAN (Metropolitan Area Network) covers a larger geographic area, such as a city or town. PAN (Personal Area Network) is a network used for communication between personal devices, such as smartphones and laptops.

Question 12

Which of the following is the correct order of networks from largest to smallest?

Accepted Answer

The correct order from largest to smallest is WAN (Wide Area Network), MAN (Metropolitan Area Network), LAN (Local Area Network), and PAN (Personal Area Network).

Question 13

________ modems operate over coaxial cable.

Accepted Answer

Cable modems are designed to operate over coaxial cable, which is the same type of cable used by cable TV providers. This allows cable internet providers to offer high-speed broadband internet services to their customers. Dial-up modems operate over phone lines, DSL modems operate over telephone lines, and fiber modems operate over fiber-optic cables.

Question 14

________ modems convert information for use on the POTS and are almost extinct in most parts of the developed world today.

Accepted Answer

Dial-up modems convert digital information to analog signals for use on the Plain Old Telephone System (POTS). However, they are almost extinct in most parts of the developed world today due to the prevalence of high-speed internet options such as cable, DSL, and fiber.

Question 15

Eriteans who have access to the Internet typically use ________.

Accepted Answer

Eritrea has limited internet infrastructure, and many users rely on dial-up connections due to the lack of widespread broadband services.

Question 16

NICs allow devices to physically connect to the _______'s communications medium.

Accepted Answer

NICs (Network Interface Card) are used to connect devices to a LAN (Local Area Network) by physically connecting them to the communications medium of the LAN, such as Ethernet cables or Wi-Fi signals. While NICs can potentially be used with other types of networks (MAN, PAN, WAN), LANs are the most common use case for NICs.

Question 17

________ modems convert information for use on the POTS.

Accepted Answer

Dial-up modems convert digital signals from a computer into analog signals that can be transmitted over POTS (Plain Old Telephone Service) lines. Cable and DSL modems are used for high-speed internet connections over cable or phone lines, respectively. Fiber modems are used for fiber optic internet connections.

Question 18

Bandwidth is stated in ________ per second.

Accepted Answer

Bandwidth is usually stated in bits per second (bps), which represents the amount of data that can be transferred over a network connection in a second.

Question 19

_________s cover large geographical areas.

Accepted Answer

WANs (Wide Area Networks) cover large geographical areas, such as cities, countries, or even the entire world. These networks are used to connect LANs and MANs across long distances, utilizing technologies such as leased lines, satellite links, and microwave connections. LANs (Local Area Networks) cover smaller areas, such as a single building or office, while MANs (Metropolitan Area Networks) cover a larger area than a LAN but smaller than a WAN. PANs (Personal Area Networks) cover a very small area, such as a person's workspace or home.

Question 20

________ is a cloud-based team communication and collaboration software program that helps company employees communicate in real time.

Accepted Answer

Slack is a well-known cloud-based team communication and collaboration software program that enables real-time communication between company employees.
