Question 1

A physical ring is a(n)____ topology.

Accepted Answer

B

Question 2

A(n)____ attached to each end of a cable prevents signals from bouncing on a physical bus.

Accepted Answer

A terminator is specifically designed to absorb any signals that are sent to it, preventing them from reflecting back on the cable and causing signal interference or loss of data. Servers, hubs, and access points are not designed for this purpose.

Question 3

All computers, no matter what their topology, communicate in the same way: They address data to one or more computers and then transmit that data across the cable in the form of ____.

Accepted Answer

Computers communicate by transmitting data as electronic signals across cables or networks.

Question 4

A network's topology has a significant effect on its performance and growth potential.

Accepted Answer

The network topology determines the structure of the network and the way in which nodes communicate with each other. The performance and growth potential of a network depend on the chosen topology, as some topologies may limit the network's bandwidth, scalability, and fault tolerance. Therefore, selecting the appropriate topology is essential in ensuring an efficient and effective network.

Question 5

In a(n)____ topology network, computers and other devices attached to the network regenerate signals and are responsible for moving data through the network.

Accepted Answer

In an active topology network, devices such as switches, routers, and hubs are responsible for regenerating signals and forwarding data through the network. Therefore, option B is the correct choice. Option A (passive topology) refers to a network where devices do not actively regenerate signals or forward data, while option C (physical topology) and option D (logical topology) refer to the physical layout and logical structure of the network, respectively, and not the mode of signal regeneration and data forwarding.

Question 6

At the center of a logical ring implemented as a physical star is a device called a(n)____.

Accepted Answer

In a logical ring topology implemented as a physical star, a concentrator is used at the center to manage the data flow between the connected devices.

Question 7

All network designs today are based on ____ simple physical topologies.

Accepted Answer

All network designs today are based on three simple physical topologies: bus, star, and ring.

Question 8

A physical bus topology is almost always implemented as a logical ____ topology.

Accepted Answer

A physical bus topology is typically implemented as a logical bus topology, where all devices share a single communication line.

Question 9

In the simplest wireless configuration, two computers can communicate directly with one another in a(n)____ topology.

Accepted Answer

Ad hoc topology allows for direct communication between two computers without the need for an access point or other infrastructure.

Question 10

The first step in any network design is to evaluate the underlying requirements.

Accepted Answer

Evaluating the underlying requirements of a network is the first and foremost step in any network design process. It is essential to understand the goals, objectives, and necessities of the organization while building a network.

Question 11

A disadvantage of the ring topology lies in its inability to share network resources fairly.

Accepted Answer

In a ring topology, data travels in one direction, and each device has equal access to the network, allowing for fair sharing of resources.

Question 12

When wireless devices are configured to use an access point, they are said to be in ____ mode.

Accepted Answer

When wireless devices are configured to use an access point, they are said to be in infrastructure mode. This mode is the most common type of wireless network, where devices connect to a central access point or router that serves as a bridge to the wired network. Ad hoc mode, on the other hand, is a peer-to-peer network between devices without a central access point. Point-to-point mode refers to a direct wireless connection between two devices. Therefore, the correct answer is C - infrastructure mode.

Question 13

In a physical ring topology, signals typically travel in both directions around the ring.

Accepted Answer

In a physical ring topology, signals typically travel in one direction around the ring, either clockwise or counterclockwise, to reach all devices.

Question 14

Because of the ____ phenomenon, a method to ensure that all signals stop when they reach the end of any segment in a bus topology must be devised.

Accepted Answer

Signal bounce occurs when signals reflect back along the transmission medium, which can cause interference and data loss. Proper termination is needed to prevent this in a bus topology.

Question 15

In most situations, wireless LANs use a central device, called a(n)____, to control communications.

Accepted Answer

An access point is a central device in a wireless LAN that controls communications and provides a connection between wireless devices and a wired network. Hubs, switches, and concentrators are typically used in wired LANs, not wireless LANs.

Question 16

At the center of a logical bus implemented as a physical star is a device called a(n)____.

Accepted Answer

A hub is a device that connects multiple Ethernet devices together and operates as a central point for data exchange. In a logical bus implemented as a physical star, the hub serves as the central point, connecting each device to the bus.

Question 17

The mesh network topology is the most expensive one.

Accepted Answer

Mesh network topology requires a large number of connections and hardware, making it more costly compared to other topologies like star or bus.

Question 18

The ring-based technologies implemented as a physical star include ____ and token ring.

Accepted Answer

The ring-based technologies implemented as a physical star include FDDI (Fiber Distributed Data Interface). FDDI is a high-speed LAN technology that operates at speeds of up to 100 Mbps. It uses a dual token ring architecture, with two rings, one for data transmission, and the other for backup.

Question 19

Signals on a bus generated by the signal bounce effect significantly reduce the performance, but do not render computer communication on the bus network unworkable.

Accepted Answer

The answer of Signals on a bus generated by the...

Question 20

On a bus network, open ends in a cable segment must be terminated to prevent ____.

Accepted Answer

In a bus network, signals are sent across a single cable segment, so if one end of the cable is left open, signals will bounce back and forth along the cable segment, causing signal interference and ultimately resulting in data loss. Therefore, cable segments must be terminated with resistors to absorb these bouncing signals and prevent signal bounce.

Quiz 2: Network Design Essentials

A physical ring is a(n) ____ topology.

A(n) ____ attached to each end of a cable prevents signals from bouncing on a physical bus.
