Question1
TheoutputoftheshowframerelaypvccommandshowsPVCSTATUS=INACTIVE.Whatdoesthismean?
A.ThePVCisconfiguredcorrectlyandisoperatingnormally,butnodatapacketshavebeendetectedformorethanfiveminutes.B.ThePVCisconfiguredcorrectly,isoperatingnormallyandisnolongeractivelyseekingtheaddresstheremoteroute.C.ThePVCisconfiguredcorrectly,isoperatingnormallyandiswaitingforinterestingtotriggeracalltotheremoterouter.D.ThePVCisconfiguredcorrectlyonthelocalswitch,butthereisaproblemontheremoteendofthePVC.E.ThePVCisnotconfiguredontheswitch.
Answer:D
Explanation
ThePVCSTATUSdisplaysthestatusofthePVC.TheDCEdevicecreatesandsendsthereporttotheDTEdevices.Thereare4statuses:
+ACTIVE:thePVCisoperationalandcantransmitdata+INACTIVE:theconnectionfromthelocalroutertotheswitchisworking,buttheconnectiontotheremoterouterisnotavailable+DELETED:thePVCisnotpresentandnoLMIinformationisbeingreceivedfromtheFrameRelayswitch+STATIC:theLocalManagementInterface(LMI)mechanismontheinterfaceisdisabled(byusingthenokeepalivecommand).Thisstatusisrarelyseensoitisignoredinsomebooks.

A.showframerelaymapB.showframerelaylmiC.showinterserialD.showframerelaypvc
Answer:A
Explanation
Theshowframerelaymapcommanddisplaysthecurrentmapentriesandinformationabouttheconnections,includingencapsulationtype.
YoucancheckTable33inthefollowinglink:http://www.cisco.com/en/US/docs/ios/12_2/wan/command/reference/wrffr4.html#wp1029343
ItclearlystatesthereisaFieldwhichcanbeCiscoorIETF,whichindicatestheencapsulationtypeforthismap.WequotethatTable33hereforyourquickreference(youwillseewhatwewanttoimplyinbold):
Field DescriptionSerial1(administrativelydown)
IdentifiesaFrameRelayinterfaceanditsstatus(upordown).
ip131.108.177.177 DestinationIPaddress.
dlci177(0xB1,0x2C10)
DLCIthatidentifiesthelogicalconnectionbeingusedtoreachthisinterface.Thisvalueisdisplayedinthreeways:itsdecimalvalue(177),itshexadecimalvalue(0xB1),anditsvalueasitwouldappearonthewire(0x2C10).
static Indicateswhetherthisisastaticordynamicentry.CISCO IndicatestheencapsulationtypeforthismapeitherCISCOorIETF.TCP/IPHeaderCompression(inherited),passive(inherited)

TheshowframerelaylmigivesusinformationabouttheLMIencapsulationtypeusedbytheFrameRelayinterface,whichcanbeANSI,CISCOorQ933a.Thereforeitisnotwhatthequestionrequires(CISCOorIETF).

A:DLCI17describestheISDNcircuitbetweenR2andR3.B:DLCI17describesaPVConR2.ItcannotbeusedonR3orR1.C:DLCI17istheLayer2addressusedbyR2todescribeaPVCtoR3.D:DLCI17describesthedialupcircuitfromR2andR3totheserviceprovider.
Answer:C
Explanation
DLCIstandsforDataLinkConnectionIdentifier.DLCIvaluesareusedonFrameRelayinterfacestodistinguishbetweendifferentvirtualcircuits.DLCIshavelocalsignificancebecausetheidentifierreferencesthepointbetweenthelocalrouterandthelocalFrameRelayswitchtowhichtheDLCIisconnected.

B.lasttimePVCstatuschanged00:25:40C.inBECNpackets192D.inFECNpackets147E.inDFpackets0
Answer:C
Explanation
FirstweshouldgrasptheconceptofBECN&FECNthroughanexample:
SupposeRouterAwantstosenddatatoRouterBthroughaFrameRelaynetwork.Ifthenetworkiscongested,Switch1(aDCEdevice)willsettheFECNbitvalueofthatframeto1,indicatingthatframeexperiencedcongestioninthepathfromsourcetodestination.ThisframeisforwardedtoSwitch2andtoRouterB(withtheFECNbit=1).
Switch1knowsthatthenetworkiscongestingsoitalsosendsframesbacktoRouterAwithBECNbitsetto1toinformthatpaththroughthenetworkiscongested.
