A. Ca'le typeB. peedC. pectrum usedD. i$nal type

Answer: D

"he Base! in -0Base" refers to the Base'and si$nalin$ method . /thernetdefined 'ase'and technolo$y( which means that when a station doestransmit( it will use the entire 'andwidth on the wire and will notshare it.

multiple B channels

Answer: B

D1 *nte$rated er#ices Di$ital 1etwor), is a di$ital ser#ice desi$nedto run o#er e%istin$ telephone networ)s. t can support #oice( #ideo(and data simultaneously. t has faster call setup than a modem and alsohas faster data rates than a modem connection.

"here are three switchin$ modes: Cut2throu$h( store2and2forward( and amodified #ersion of cut2throu$h. Re$ardin$ this modified #ersion( whichof the followin$ is true?

A. tore2and2forward has a lower latencyB. Cut2throu$h has a hi$her latencyC. t waits until 305 of the data in the pac)et has come into the switch

'efore forwardin$ itD. t waits until the data portion of the pac)et reaches the switch

'efore forwardin$ it

Answer: D

"he modified #ersion of cut2throu$h switchin$ is called 6ra$ment6ree. twill wait until the first 47 'ytes of the pac)et pass throu$h the switch'efore forwardin$ it. "he data portion of the pac)et 'e$ins after the 47'ytes. "his switchin$ method is the default for Cisco -800 seriesswitches. tore2and2forward has a hi$her latency than 6ra$ment6ree'ecause it copies the whole frame onto its on'oard 'uffers and thencomputes a cyclic redundancy chec) *CRC, 'efore forwardin$ it. Cut2throu$h has a lower latency 'ecause it only copies the destinationaddress of the frame onto its on'oard 'uffers 'efore forwardin$ it.
