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.
