Question 1

Routers can prevent network slowdowns and broadcast storms.

Accepted Answer

Routers can prevent network slowdowns and broadcast storms by separating broadcast domains and implementing network segmentation.

Question 2

A(n)USB is a standard for connecting all kinds of peripherals, such as printers, modems, and tape drives, and in many cases is replacing the use of traditional parallel and serial ports.

Accepted Answer

This statement is true. USB (Universal Serial Bus) has become a widely used standard for connecting various peripherals to computers, and it has largely replaced the use of parallel and serial ports for this purpose.

Question 3

The MAC controller unit works at the OSI ____ layer.
A)Data Link
B)Physical
C)Transport
D)Both A and B.

Accepted Answer

The MAC (Media Access Control) controller unit operates at the Data Link layer of the OSI model. This layer is responsible for managing access to the network medium and ensuring the reliable transmission of data over the physical layer.

Question 4

Different NICs are used for different media and transport methods.

Accepted Answer

Different types of NICs support different media (such as copper or fiber-optic cables) and transport methods (such as Ethernet or Wi-Fi).

Question 5

When a PC is connected to a modem, the data transfer speed of the PC is the data communications equipment communications rate.

Accepted Answer

The data transfer speed of a PC when connected to a modem is determined by the slower of the two devices' maximum speeds, which could be the modem's data communication equipment (DCE) rate or the PC's data terminal equipment (DTE) rate, along with the quality of the connection and the service plan from the internet service provider.

Question 6

A(n)broadcast flood is the saturation of network bandwidth by excessive transmissions from devices attached to the network, which can result in a virtual standstill of traffic.

Accepted Answer

The answer of A(n)broadcast flood is the saturation of network...

Question 7

Hubs offer the ability to segment network traffic, limiting traffic to those networks where it belongs.

Accepted Answer

Hubs operate at the physical layer of the OSI model and simply replicate all incoming traffic to all connected devices. This means that there is no segmentation of network traffic and traffic is broadcasted to all devices connected to the hub.

Question 8

The M in MNP stands for modem.

Accepted Answer

The M in MNP stands for Microcom Networking Protocol.

Question 9

Intelligent bridges are used to join distant networks.

Accepted Answer

Intelligent bridges, also known as smart bridges, primarily filter network traffic to manage the flow of data and reduce congestion within a single network or between closely linked network segments, rather than joining distant networks.

Question 10

A cable segment is one cable run within the IEEE specifications.

Accepted Answer

A cable segment is defined as one cable run within the IEEE specifications for network topology.

Question 11

It is not important to become familiar with older-style networks, because they are almost obsolete.

Accepted Answer

It is still important to be familiar with older-style networks because many companies still rely on these networks and may not be able to upgrade immediately to newer systems. Additionally, knowledge of older-style networks can be helpful in understanding the evolution of networking technology and troubleshooting legacy systems.

Question 12

The link-state routing message is associated with RIP.

Accepted Answer

The link-state routing message is associated with OSPF, not RIP. RIP uses distance-vector routing messages.

Question 13

A global router enables networks to be connected into WANs over long distances, say from New York to Los Angeles.

Accepted Answer

The answer of A global router enables networks to be...

Question 14

The most traditional type of gateway is a network device that translates one type of protocol to another that has a very different structural composition.

Accepted Answer

This is true. A traditional gateway acts as a protocol translator between two networks, allowing them to communicate even if they use different protocols or formats.

Question 15

Routers, like bridges, are transparent to other network nodes, such as workstations and servers.

Accepted Answer

Unlike bridges, routers examine and make decisions based on network layer information, such as IP addresses. They are not transparent to other network nodes and actively participate in the routing process.

Question 16

Driver encoding means that a digital signature is placed in the driver.

Accepted Answer

Driver encoding typically refers to the process of converting driver data into a specific format for transmission or storage, not to the placement of a digital signature in the driver. Digital signatures are used to verify the authenticity and integrity of the driver, but this process is more accurately referred to as driver signing.

Question 17

A ____ is a device that can transmit and receive, such as transmitting and receiving signals on a communications cable.
A)multiplexer
B)transmitter
C)transceiver
D)portal

Accepted Answer

A transceiver is a device that can both transmit and receive signals. Multiplexers and transmitters only send signals, while portals is not a common term for a communication device.

Question 18

A channel bank is a large-scale multiplexer that aggregates telecommunications channels in a centralized location such as a POP.

Accepted Answer

A channel bank is indeed a large-scale multiplexer that aggregates telecommunications channels in a centralized location such as a POP.

Question 19

Local routers are used to segment network traffic and to enforce security.

Accepted Answer

Local routers can be used to create separate network segments, each with their own security policies and restrictions. This can help to prevent unauthorized access and limit the impact of any security breaches that may occur.

Question 20

Unmanaged hubs are best for networks with a large number of nodes.

Accepted Answer

Unmanaged hubs are not recommended for large networks as they can cause issues with network congestion, collisions, and slow data transfer speeds. Managed switches or routers are better suited for larger networks as they can prioritize traffic and optimize performance.
