Exam 11: Local Area Network Overview

Store-and-forward switch and cut-through switch are two types of ________ switches that are available as commercial products.

The bridge provides an extension to the LAN once modifications to the communications software in the stations attached to the LAN are made.

A ________ is where the destination MAC address indicates that all devices on the LAN should receive a copy of the frame.

In the ________ topology each station is directly connected to a common central node,typically via two point-to-point links,one for transmission and one for reception.

The choice for transmission medium and topology is critical in LAN design.

The ________ topology is a special case of the tree topology,with only one trunk and no branches.

The key elements of a local area network are medium access control,transmission medium,wiring layout,and ________.

The basic logical link control protocol is modeled after ________ and has similar functions and formats.

A transmission of a frame by any one station in a bus or tree topology can be heard by other stations.

Each station attaches to the network at a repeater in the star topology and can transmit data onto the network through the repeater.

A hub can be configured to recognize a malfunctioning station that is jamming the network and to cut that station out of the network.

Switches and hubs form the basic building blocks of most local area networks.

The key elements of the local area network determine the cost and capacity of the LAN,the type of data that may be transmitted,the speed and efficiency of communications,and the kinds of applications that can be supported.

The principle disadvantage of VLAN "membership by port group" is that ________.

The network consists of a set of ________ joined by point-to-point links in a closed loop in the ring topology.These are capable of receiving data on one link and transmitting them,bit by bit,on the other link as fast as they are received.

The simplest approach to interconnecting multiple LANs within an organization is to use a ________.

There are four alternative media that can be used for a bus LAN: baseband coaxial cable,broadband coaxial cable,optical fiber,and ________.

A ________ local area network consists of a closed loop of repeaters that allow data to circulate around the ring.

Which of the following is NOT a characteristic of a bridge?

Transmission is generally in the form of frames when using a ring topology.
