Question 1

Case-Based Critical Thinking Questions Case 7-2 Gabrielle is the network administrator at a medium-sized company. One of her responsibilities is to purchase network devices to maintain the company network. Gabrielle is planning to connect selected devices to the network wirelessly with a ____.
A) hotspot
B) wireless  access point
C) hub
D) switch

Accepted Answer

A wireless access point is the appropriate device to provide wireless connectivity to selected devices on the network. A hotspot is a location where wireless internet access is available, typically through a public wireless network. Hubs and switches are used to connect devices on a network through wired connections, not wireless.

Question 4

____ satellites travel at a speed and direction that keeps pace with the earth's rotation, so they appear (from earth) to remain stationary over a given spot.
A) Microwave
B) Geosynchronous
C) Isochronous
D) Full-duplex transmission

Accepted Answer

Geosynchronous satellites orbit at the same rate as the rotation of the earth, allowing them to remain stationary over a particular location. Microwave satellites refer to the frequency range they use, isochronous does not relate to satellite orbits, and full-duplex transmission refers to a method of sending and receiving data simultaneously.

Question 5

Technically, to be called a ____, a device must convert digital signals (such as those used by a computer) to modulated analog signals (such as those used by conventional telephone lines) and vice versa.
A) hub
B) modem
C) switch
D) router

Accepted Answer

A modem is the only device in the list that is specifically designed to convert digital signals to modulated analog signals and vice versa. Hubs, switches, and routers are all networking devices that deal with digital signals.

C) 802.11ax
D) 802.11ac

Accepted Answer

The proposed Wi-Fi standard that is expected to support speeds of more than 2 Gbps is 802.11ax. 802.11a, 802.11g, and 802.11ac are all existing Wi-Fi standards but do not support speeds of more than 2 Gbps.

A) telemarketing
B) telecommuting
C) videoconferencing
D) e-working

Accepted Answer

Robert's job is a telecommuting job because he is working from home for a pharmaceutical company. Telemarketing refers to sales over the phone, videoconferencing refers to virtual meetings, and e-working is a general term for electronic work.

Question 10

____________________ can be included in a network anytime there is a situation with measurable criteria that needs precise, automatic, and continual monitoring.

Accepted Answer

The answer of ____________________ can be included in a network anytime...

Question 11

A network adapter, also called a ____ when it is in the form of an expansion card, is used to connect a computer to a network.
A) network interface card (NIC)
B) powerline card
C) data communications card (DCC)
D) USB

Accepted Answer

A network adapter is also known as a NIC (network interface card) when it is in the form of an expansion card. Option B (powerline card) refers to a device that uses a building's electrical wiring to extend a network's reach, while option C (data communications card) is a generic term that does not specifically refer to network connectivity. Option D (USB) is a type of port used to connect devices to a computer, but it is not a network adapter. Therefore, the best choice is A.

Question 12

Case-Based Critical Thinking Questions Case 7-2 Gabrielle is the network administrator at a medium-sized company. One of her responsibilities is to purchase network devices to maintain the company network. Gabrielle realizes that to improve network performance, she needs to buy and install a ____, which identifies the device on the network for which the data is intended and sends the data to that device only.
A) switch
B) node
C) bus
D) bridge

Accepted Answer

A switch is a device that connects devices on a network and allows them to communicate with each other by forwarding data packets. A switch uses MAC addresses to identify devices on the network and sends data only to the device for which it is intended. A node is a device connected to a network, but it does not improve network performance. A bus is a type of network topology, and a bridge is an older type of networking device that connects two network segments together.

Question 13

One of the key enhancements in ____ is energy efficiency.
A) piconets
B) PANs
C) Bluetooth 5.0
D) Bluetooth Smart

Accepted Answer

The answer of One of the key enhancements in ____ is...

Question 14

A ____ transmits all data received to all network devices connected to it, regardless of which device the data is being sent to.
A) bridge
B) router
C) gateway
D) hub

Accepted Answer

A hub operates at the physical layer (layer 1) of the OSI model and broadcasts any data it receives to all connected devices, without any regard for the destination address. Therefore, a hub is a basic device that simply connects multiple devices to create a network. Bridges, routers, and gateways operate at higher layers of the OSI model and make decisions based on destination addresses, allowing for more efficient and secure communication within a network.

Question 15

Similar to Wi-Fi, ____ is designed to provide Internet access to fixed locations (sometimes called hotzones), but the coverage is significantly larger.
A) WinMax
B) EMax
C) 802.16a
D) 802.11b

Accepted Answer

802.16a, also known as WiMAX, is designed to provide long-range wireless broadband access to fixed locations, covering a significantly larger area than Wi-Fi. WinMax and EMax are not recognized wireless standards, and 802.11b is a Wi-Fi standard, but it has a shorter range than 802.16a.

Question 16

Case-Based Critical Thinking Questions Case 7-2 Gabrielle is the network administrator at a medium-sized company. One of her responsibilities is to purchase network devices to maintain the company network. Gabrielle would like to purchase a new ____, which would be used to connect the company's LAN and the Internet.
A) hub
B) USB port
C) router
D) bridge

Accepted Answer

A router is the best choice because it connects different networks and directs traffic between them, making it a suitable device to connect the LAN and the Internet. A hub only connects devices on the same network segment, a USB port is not a networking device, and a bridge is used to connect two LAN segments together but does not have the capability to connect a LAN and the Internet.

Question 17

The original first-generation cell phones were ____ and designed for voice data only.
A) digital
B) discrete
C) analog
D) magnetic

Accepted Answer

The original first-generation cell phones were analog and designed for voice data only. Digital phones came later and brought with them texting, internet access, and other features. Discrete and magnetic do not accurately describe first-generation cell phones.

Question 18

____ is typically used with LANs that have a star topology and can be used in conjunction with twisted-pair, coaxial, or fiber-optic cabling.
A) Ethernet
B) Token Ring
C) Wi-Fi
D) 80xx2.11

Accepted Answer

Ethernet is the most commonly used LAN protocol and is compatible with a wide range of cabling types including twisted-pair, coaxial, and fiber-optic. Token Ring is a LAN protocol that is now considered obsolete, and Wi-Fi and 80xx2.11 are wireless network protocols that are not typically used with LANs that have a star topology.

Question 19

Case-Based Critical Thinking Questions Case 7-1 Robert is a medical writer for a pharmaceutical company. The company allows Robert to work from home. Every day, Robert uses ____ to have a real-time, face-to-face meeting with his boss.
A) intranets
B) telemarketing
C) virtual networks
D) videoconferencing

Accepted Answer

Videoconferencing is the most suitable choice for Robert to have a real-time, face-to-face meeting with his boss while working from home. Intranets are internal networks that allow employees to access company resources and information. Telemarketing is a sales strategy that involves calling potential customers by phone. Virtual networks can refer to various types of computer networks but do not necessarily offer face-to-face communication.

Question 20

____ is a networking standard for very short-range wireless connections; the devices are automatically connected once they get within the allowable range.
A) IrDA
B) xMax
C) Wi-Fi
D) Bluetooth

Accepted Answer

Bluetooth is a networking standard for very short-range wireless connections. Devices are automatically connected once they get within the allowable range, usually around 30 feet.
