Exam 13: Ethernet, switches, and Virtual Lans

In general,the performance of a LAN declines with increased lengths of connections and / or the number of devices using it.

Segmenting a larger network into ___________ domains can help to prevent a fault in one network segment from affecting the entire network.

A broadcast recipient address means that all devices connected to the LAN are to receive the message.

This option makes use of four pairs of Category 5 UTP to support devices over a range of up to 100 m.

Two general approaches to connecting multiple LANs are bridges and switches.

A _________ provides a means of interconnecting similar LANs.

___________ provides a low-cost,easily scalable approach to achieving very high data rates and is used in storage area networks (SANs)and for other types of storage networking.

In the MAC frame,the start of frame delimited (SFD)provides the receiver with the starting point of meaningful data in the frame.

The __________ is a data unit supplied by LLC.The maximum size of this field is 1500 octets for a basic frame,1504 octets for a Q-tagged frame,and 1982 octets for an envelope frame.

Network topology refers to the way individual end stations access the network prior to transmission of user data.

A _________ is octets added to ensure that the frame is long enough for proper CD operation.

The _________ specifies the station that sent the frame.

Two major types of layer 2 switches are available for use in business networks: store-and-forward switch and ____________.

The frame format for the 802.3 protocol consists of:

In general,performance on a LAN _________ with an increase in the number of devices or the length of the wire.

VLANs provide the ability for any organization to be physically dispersed throughout the company while maintaining its group identity.

The __________ is a 32-bit cyclic redundancy check (CRC), based on all fields except preamble,SFD,and FCS.

Which of the following LAN technologies has the highest capacity?

Which of the following is not one of the speeds found in a modern Ethernet LAN?

Every MAC frame must include two addresses,which allows an alternative receiver to be designated in the event an error occurs.
