What should you tell her？ （）
A.The FIB lookup is based on the Layer 3 destination address prefix （shortest match）.
B.The adjacent table is derived from the ARP table.
C.The FIB table is derived from the IP routing table.
D.When the adjacency table is full， a CEF TCAM table entry points to the Layer 3 engine to redirect the adjacency.
E.CEF IP destination prefixes are stored in the TCAM table， from the least specific to the most specific entry.
F.When the CEF TCAM table is full， packets are dropped.

The network administrator has enabled BPDU guard on the LAN.
Why is an effective way to prevent an unauthorized rogue switch from altering the spanning-tree topology of this network？ （）
A.BPDU guard can be used to prevent invalid BPDUs from propagating throughout the network.
B.BPDU guard can guarantee proper selection of the root bridge.
C.BPDU guard can be utilized to prevent the switch from transmitteing BPDUs and incorrectly altering the root bridge election.

What is the sequence of events when a VoIP call is placed from IP phone P1 to IP phone P2？ （）
A.RTP traffic is exchanged between IP phone P1 and IP phone P2. IP phone P1 alerts the CCM of off-hook state. CCM instructs IP phone P1 to provide dialtone. IP phone P1 passes digits to CCM. CCM routes call to PSTN or IP phone P2.
B.CCM instructs IP phone P1 to provide dialtone. IP phone P1 alerts the CCM of off-hook state. IP phone P1 passes digits to CCM. CCM routes call to PSTN or IP phone P2. RTP traffic is exchanged between IP phone P1 and IP phone P2.
C.CCM instructs IP phone P1 to provide dialtone.IP phone P1 alerts the CCM of off-hook state. IP phone P1 passes digits to CCM. RTP traffic is exchanged between IP phone P1 and IP phone P2. CCM routes call to PSTN or IP phone P2.
D.IP phone P1 alerts the CCM of off-hook state. CCM instructs IP phone P1 to provide dialtone. IP phone P1 passes digits to CCM. CCM routes call to PSTN or IP phone P2. RTP traffic is exchanged between IP phone P1 and IP phone P2.

What will happen if the access point receives packets sent by the wireless client adapter that are not encrypted with the appropriate key？（）
A.The wireless client adapter will not be authenticated by the authentication server， but the access point deliver the packets to the intended receiver.
B.The wireless client adapter will not be able to send any packets to the access point.
C.The access point will discard the packets and never deliver them to the intended receiver.
D.The wireless client adapter will be authenticated by the authentication server and the access point will deliver the packets to the intended receiver.
