Which two statements describe traffic policing？（）

• A、Traffic bursts are smoothed out by queuing the excess traffic to produce a steadier flow of data
• B、Excess traffic is buffered so that the traffic remains within the desired rate.
• C、Packets that conform to traffic policies are not delayed.
• D、Packet marking is available and allows excess packets to be re-marked with a lower priorit

第4题：

Which three characteristics of the traffic flow are taken into consideration when the QoS-for-VPNs feature （QoS pre-classify） provides packet classification and applies appropriate QoS service on tunnel interfaces？（）

• A、IP precedence bits
• B、DSCP bits
• C、original port numbers
• D、DE bits
• E、source IP address
• F、destination IP address

第5题：

Which statement about IDS/IPS design is correct?（）

• A、An IPS should be deployed if the security policy does not support the denial of traffic.
• B、An IPS analyzes a copy of the monitored traffic and not the actual forwarded packet.
• C、An IDS analyzes a copy of the monitored traffic and not the actual forwarded packet.
• D、Bandwidth considerations must be taken into account since IDS is deployed inline to traffic flow.

vPath is a critical component in the VNS architecture. Which two are functions of vPath？（）

• A、 intelligent traffic steering to the VSG
• B、 offloading the processing from the VSG to the VEM
• C、 intelligent traffic steering to the VNMC
• D、 offloading the processing from the VSG to the flow manager

第9题：

If an edge Label Switch Router （LSR） is properly configured，which three combinations are possible？（）

• A、A received IP packet is forwarded based on the IP destination address and the packet is sent as an IP packet.
• B、An IP destination exists in the IP forwarding table. A received labeled packet is dropped because the label is not found in the LFIB table.
• C、There is an MPLS label-switched path toward the destination. A received IP packet is dropped because the destination is not found in the IP forwarding table.
• D、A received IP packet is forwarded based on the IP destination address and the packet is sent as a labeled packet.
• E、A received labeled IP packet is forwarded based upon both the label and the IP address.
• F、A received labeled packet is forwarded based on the label. After the label is swapped，the newly labeled packet is sent.

第10题：

Which of the following is TRUE about the ping  -f command?（）

• A、 It is useful for diagnosing data dependent problems by filling the packet with the byte pattern following the "f" in the command line. 
• B、 It is useful for flooding from slow character based terminals since it only displays a dot "." for each packet sent in fast mode. 
• C、 It is useful for flooding from slow character based terminals since it only displays a dot "."       for each packet sent and a backspace on returned in fast mode. 
• D、 The command can only be run by root.
