Question 1

The term "cloud" is used to refer to the elastic leasing of pooled computer resources over the Internet.

Accepted Answer

The definition of "cloud" as the elastic leasing of pooled computer resources over the Internet is a widely accepted industry definition.

Question 2

One of the advantages of cloud-based hosting, as long as it is with reputable organizations, is the best-of-breed security and disaster recovery.

Accepted Answer

Cloud-based hosting with reputable organizations often offers high levels of security and disaster recovery capabilities, making it an advantage over other hosting options.

Question 3

A computer network is a collection of computers that communicate with one another over transmission lines or wirelessly.

Accepted Answer

This statement is true.

Question 4

An intranet is a private internet that is used exclusively within an organization.

Accepted Answer

An intranet is a private network that can only be accessed by employees or members of an organization. It is used to share information and resources within the organization, and it is not accessible to the public or external parties.

Question 5

When a person connects to the Internet, he or she is actually connecting to an Internet Service Provider.

Accepted Answer

When a person connects to the Internet, they need to have an Internet Service Provider (ISP) to provide them with internet access. The ISP is responsible for connecting the user to the Internet and ensuring that they can browse websites, send and receive emails, and perform other tasks online. Without an ISP, a person cannot connect to the Internet.

Question 6

Wired LAN connections use the IEEE 802.3 protocol, whereas wireless LAN connections use the IEEE 802.11 protocol.

Accepted Answer

Wired LAN connections use the IEEE 802.3 protocol, and wireless LAN connections use the IEEE 802.11 protocol.

Question 7

With a WAN, an organization is allowed to place communications lines wherever it wants, because all lines reside on its premises.

Accepted Answer

With a WAN, an organization is not allowed to place communications lines wherever it wants, as WANs typically span multiple locations and may involve leased lines or connections with service providers.

Question 8

Wired LAN connections use a protocol standard called Ethernet to communicate.

Accepted Answer

Wired LAN connections typically use Ethernet as the protocol standard for communication.

Question 11

Bluetooth is a common wired protocol designed to transmit data over long distances.

Accepted Answer

Bluetooth is actually a wireless protocol and is designed to transmit data over short distances.

Question 12

A university would use a WAN to connect its campuses in two cities.

Accepted Answer

A WAN (Wide Area Network) is a network that covers a broad geographic area and is typically used to connect multiple smaller networks, such as local area networks (LANs) or metropolitan area networks (MANs). Connecting campuses in two different cities would require a WAN.

Question 13

A switch detects the speed that a given device can handle and communicates with it at that speed.

Accepted Answer

A switch is designed to analyze the data packets and detect the device speed before sending data to the intended device. This allows the switch to communicate with each device at the appropriate speed, ensuring better network performance.

Question 14

Communication speeds are expressed in bytes, whereas memory sizes are expressed in bits.

Accepted Answer

Communication speeds are typically expressed in bits, while memory sizes are typically expressed in bytes.

Question 15

A computer network between Seattle and Philadelphia is made possible through a LAN.

Accepted Answer

A LAN (Local Area Network) is typically used for small geographical areas, such as within a building or campus. To connect two cities, a WAN (Wide Area Network) would be needed.

Question 16

IEEE LAN protocols always start with the numbers 802.

Accepted Answer

This is true. IEEE LAN protocols are standardized under the IEEE 802 family of standards.

Question 17

An Internet is a network of networks that connects LANs, WANs, and other internets.

Accepted Answer

An Internet is indeed a network of networks that connects different types of networks, including LANs (local area networks), WANs (wide area networks), and other internets. This allows devices and users from different networks to communicate and share information with one another.

Question 18

The term "pooled" can be used to describe the cloud as different organizations use the cloud to share hardware through virtualization.

Accepted Answer

This is correct as the concept of pooling resources is a key feature of cloud computing, where multiple organizations can access and share the same physical hardware through virtualization technology.

Question 19

Cloud-based hosting is the ideal choice for organizations that are required by law to have physical control over their data.

Accepted Answer

Cloud-based hosting means that the data is stored on servers owned by a third-party provider, which means that the organization does not have physical control over their data. This may not be the ideal choice for organizations that require physical control over their data due to legal or regulatory requirements.

Question 20

The committee that addresses LAN standards is called the ICANN.

Accepted Answer

The committee that addresses LAN standards is not called the ICANN. ICANN stands for Internet Corporation for Assigned Names and Numbers and is responsible for managing the domain name system (DNS) of the Internet. The committee that addresses LAN standards is the Institute of Electrical and Electronics Engineers (IEEE) 802 committee.
