NetFlow Questions
Question 1
Explanation
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
Explanation
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 10.42.42.1 9991
ip flow-export destination 10.0.101.254 1999

Question 4
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.
