Exam 350-401 topic 1 question 446 discussion

Just need to apply the flow monitor and the sampler to the interface. Sampler already capturing 50 out of 100 (1 out of 2)

A. sampler SAMPLER-1 mode random 1-out-of 2 flow FLOW-MONITOR-1 interface GigabitEthernet 0/0/0 ip flow monitor SAMPLER-1 input B. flow monitor FLOW-MONITOR-1 record v4_r1 sampler SAMPLER-1 interface GigabitEthernet 0/0/0 ip flow monitor FLOW-MONITOR-1 sampler SAMPLER-1 input C. sampler SAMPLER-1 no mode random 1-out-of 2 mode percent 50 interface GigabitEthernet 0/0/0 ip flow monitor FLOW-MONITOR-1 sampler SAMPLER-1 input D. interface GigabitEthernet 0/0/0 ip flow monitor FLOW-MONITOR-1 sampler SAMPLER-1 input

The only configuration missing from the exhibit is assigning the sampler to sample the NetFlow traffic on the monitored interface.

D is correct

I checked Cisco documentation Associates an IPv4 flow monitor and an optional sampler to the interface for input or output packets. ip flow monitor name [sampler name] { input |output }

configuration of sampler was only thing not covered in OCG.

What doesn't help analyzing the answers is not having the indentations/config mode for each statement. B and D are similar, with Bappearing you're retyping what's already there. But I think B was saying to put the sampler definition within the monitor definition and that's wrong.

Everything is complete and configured correctly, we just have to apply it on an interface. The answer is D.

Dis correct. Example: Device(config-if)# ip flow monitor FLOW-MONITOR-1 sampler SAMPLER-1 input

D is correct

Answer D is correct. Analysing 1-out-of 2 is analysing 50 percent.

Correct answer is c
