STPB. TTLC.fabric tagsD. FSTPCorrect Answer: CSection: (none)ExplanationExplanation/Reference:Well, the dump said "TTL" and I think that's not entirely true.TTL ends up a looping packet but the loop can still be there.Fabric path uses IS-IS and the concept of "switch-ids" which could refer to "fabric tags"...There are also the FTag (Forwarding Tag) which specifies which path the packet traverses...Not very clear.If the Q was something like : "Which option does the FabricPath technology use to mitigateLayer 2loops ?"I would have answered TTL.QUESTION 90Which Cisco NAC Appliance component is optional?A.NAC Appliance ManagerB.NAC Appliance ServerC.NAC Appliance AgentD.NAC Appliance Policy UpdatesCorrect Answer: CSection: (none)ExplanationExplanation/Reference:-00.html#sol-comp
"The Cisco NAC Agent is an optional component of the Cisco NAC solution."QUESTION 91Which option describes the effect of using softphones instead of VoIP handsets on QoS implementation for thevoice traffic?A.It provides a Layer 2 CoS marking in the frames that can be used for QoS implementation.B.Using softphones means that 802.1Q tagging must be configured between the PC and the switch.C.The voice traffic of softphones is mixed with data traffic of PC on the access VLAN.D.By using softphones, the implementation of a QoS depends only on trusting DSCP markings set by the PC.Correct Answer: CSection: (none)ExplanationExplanation/Reference:QUESTION 92Which part of the Layer 3 header is used to identify a flow in NetFlow but it is not used for NBAR?A.source portB.
