Question 1


The “mode random one-out of 100” specifies that sampling uses the random mode and only take one sample out of every 100 packets.

Question 2

Question 3


To configure multiple NetFlow export destinations to a router, use the following commands in global configuration mode:

Step 1: Router(config)# ip flow-export destination ip-address udp-port
Step 2: Router(config)# ip flow-export destination ip-address udp-port

The following example enables the exporting of information in NetFlow cache entries:

ip flow-export destination 9991
ip flow-export destination 1999

    Q2 is C – only to add an interface config

    D is wrong because there is no subcommand “sampler” under flow monitor command

    I agree with Nick. I tried this in IOSv 15.6(2)T and I cannot find the “sampler” subcommand under flow monitor configuration mode either. Can someone check what is best answer here?

    I agree, I will choose the answer C for Q2. I reviewed the command reference and sampler is configured independent from monitor. Then they are applied together for required interface.
    @digitaltut can you reconsider the answer?

    Question 2

    Agree answer should be “C” flow monitor and flow sampler are combined on the interface.

    Q-2 I agree “C” is the correct answer Flow monitor and Flow sampler are combined when being applied on interface.
