第1题：

Which two statements are correct about the signaling methods that are utilized for transmitting voice？ （）

• A、 Channel-associated signaling transmits control signals in band and therefore reduces the bandwidth available for the voice data stream.
• B、 Channel-associated signaling utilizes a separate TDM channel for transmitting control signals.
• C、 Common channel signaling transmits control signals in band and therefore reduces the bandwidth available for the voice data stream.
• D、 Common channel signaling uses one of the TDM channels to transmit control information reducing the number of channels available for voice.
• E、 ISDN BRIs implement channel-associated signaling.

第6题：

What is the difference between the Ethanalyzer and the SPAN feature in Cisco NX-OS？（）

• A、 The Ethanalyzer captures control-plane traffic， while SPAN captures all traffic.
• B、 The Ethanalyzer captures all traffic including control-plane traffic， while SPAN captures only the control-plane traffic.
• C、 The Ethanalyzer captures only data traffic， while SPAN captures all traffic.
• D、 The Ethanalyzer captures only control traffic， while SPAN captures data traffic.

第7题：

In PIM-SM what control plane signaling must a multicast source perform before it begins to send multicasttraffic to a group？（）

• A、The source must send a PIM Register message to the rendezvous point （RP）.
• B、The source must first join the multicast group using IGMP before sending.
• C、The source must perform a Request to Send （RTS） and Clear to Send （CTS） handshake with the  PIM designated router （DR）.
• D、No control plane signaling needs to be performed； the source can simply begin sending on the local  subnet.

第9题：

Which of the following statemets regarding Control Plane Policing （CoPP） is correct？（）

• A、Control Plane Policing （CoPP） addresses the need to protect the management planes， ensuring routingstability， availability， and critical packet delivery.
• B、Control Plane Policing （CoPP） leverages MQC to define traffic classification criteria and to specifyconfigurable policy actions for the classified traffic.
• C、Control Plane Policing （CoPP） uses a dedicated "control-plane" command via the Modular QoS CLI （MQC）to provide filtering and rate limiting capabilities.
• D、Control Plane Policing （CoPP） uses "service policy" command under relevant interfaces to filter DOS packet to protect routing packets.
• E、Control Plane Policing （CoPP） protects the transit management and data traffic through the router.
