Question 1

Bridges operate at the Network layer of the OSI model.

Accepted Answer

Bridges operate at the Data Link layer of the OSI model, not the Network layer.

Question 2

Devices that &#34;see&#34; the traffic of other devices are said to be on the same ____ as those devices.&#10;A) ring&#10;B) block&#10;C) level&#10;D) collision domain

Accepted Answer

Devices that "see" the traffic of other devices are said to be on the same collision domain. A collision domain is a logical network segment in which data packets can collide with one another when being sent on a shared medium, such as a LAN. Devices on the same collision domain must contend with each other for access to the shared medium, which can lead to collisions and degraded network performance.

Question 3

A ____ filters traffic between network segments by examining the destination MAC address.&#10;A) hub&#10;B) repeater&#10;C) router&#10;D) bridge

Accepted Answer

A bridge filters traffic between network segments by examining the destination MAC address, whereas a hub and repeater simply repeat signals to all connected devices, and a router examines the network layer (IP address) in addition to the MAC address.

Question 4

____ have the most negative effect on network performance.&#10;A) Routers&#10;B) Bridges&#10;C) Switches&#10;D) Gateways

Accepted Answer

Gateways, which connect networks using different protocols, can introduce significant overhead and latency due to the need for protocol conversion, potentially having the most negative effect on network performance compared to routers, bridges, and switches that typically deal with similar protocols.

Question 5

A(n) ____ functions as both a bridge for nonroutable protocols and a router for routable protocols.&#10;A) switch&#10;B) hub&#10;C) amplifier&#10;D) brouter

Accepted Answer

A brouter is a device that functions as a bridge for nonroutable protocols and as a router for routable protocols. It is a combination of a bridge and a router, hence the name "brouter". Switches, hubs, and amplifiers do not have this capability.

Question 6

Switches filter based on ____ addresses.&#10;A) logical&#10;B) IP&#10;C) MAC&#10;D) TCP/IP

Accepted Answer

Switches filter based on MAC addresses. They examine the Media Access Control (MAC) address of incoming data packets and use that information to determine which port to send the packets to. Logical, IP, and TCP/IP addresses are used in other network devices, such as routers and firewalls, for different purposes.

Question 7

Repeaters and hubs reformat data structures, so they can connect networks that require different types of frames.

Accepted Answer

Repeaters and hubs are physical layer devices that simply amplify and regenerate signals without altering the data structure. It is bridges, routers, and switches that reformat data structures to connect networks with different frame types.

Question 8

Like bridges, switches operate at the Network layer of the OSI model.

Accepted Answer

Bridges and switches primarily operate at the Data Link layer (Layer 2) of the OSI model, facilitating network traffic based on MAC addresses.

Question 9

____ increase network performance by reducing the number of frames transmitted to the rest of the network.&#10;A) Switches&#10;B) Gateways&#10;C) Hubs&#10;D) Amplifiers

Accepted Answer

Switches operate at the data link layer and make forwarding decisions based on the MAC addresses of devices connected to them. By only forwarding frames to the necessary destination, switches reduce the amount of traffic on the network and increase performance. Gateways, on the other hand, operate at the network layer and provide connectivity between different networks. Hubs simply broadcast frames to all connected devices and do not improve network performance. Amplifiers increase the strength of signals, but do not reduce the number of frames transmitted.

Question 10

The IEEE standards for WLANs use unlicensed, but not unregulated, radio frequencies.

Accepted Answer

The IEEE standards for WLANs, such as 802.11, use unlicensed radio frequencies that do not require a license from a regulatory agency to operate, but they still must comply with certain regulations and power limitations to avoid interference with other devices operating in the same frequency band.
