Exam 7: Layer 2 Networking Protocols

An acronym for the term meaning a measure of the telephone service quality provided to a subscriber is:

The Ethernet protocol used in LAN networks is significantly different from the Ethernet protocol used in WAN networks.

Ethernet has reinvented itself as a strong contender in the fight for market dominance in the layer 2 access space.

The primary value Ethernet provides as a WAN technology is familiarity and comfort level of IT managers.

The ________ is one of the most talked-about layer 2 protocols in the network today and is developed around a 53-octet cell structure.

Which layer is responsible for placing information in the appropriate packages and giving it different priorities in the network for ATM to carry the information reliably across the network?

Most frame relay switches are categorized by switching ________.

All of the following are parameters used to define a frame relay circuit except the:

Which is not a connection oriented technology

The MAC address is a(n) ________ addressing scheme because it is not dependent upon an address hierarchy, as is an IP address.

The advantage of frame relay is its:

The purpose of the ATM protocol is to provide a way to converge all types of traffic onto one network.

Unlike frame relay, ATM does not rely on the intelligence of upper layers to ensure that information arrives uncorrupted.

________ multiplexing ATM bonds T1 circuits together to produce one large circuit that can handle a greater volume of bits at one time than multiple small circuits can.

Discard eligible means that the information is not critical and can be thrown out if the circuit experiences ________.

A frame relay switch has three components, the access interfaces, the network interfaces, and the switching fabric.

Although it is possible for voice to travel across a frame relay network, consistent use of frame relay for this purpose is difficult and unreliable.

The ________ relay protocol was meant to solve many of the problems associated with the X.25 protocol and was built to take advantage of the new digital high-speed circuits allowing for higher-speed interfaces

Unlike the router, the frame switch does not have to crack the IP packet to know where to switch or route the traffic.
