Which are two results of implementing this feature instead of traditional Netflow?

A network engineer is configuring Flexible Netflow and enters these commands

Sampler Netflow1

Mode random one-out-of 100

Interface fastethernet 1/0

Flow-sampler netflow1

Which are two results of implementing this feature instead of traditional Netflow? (Choose two.)
A . CPU and memory utilization are reduced.
B . Only the flows of top 100 talkers are exported
C . The data export flow is more secure.
D . The number of packets to be analyzed are reduced
E . The accuracy of the data to be analyzed is improved

View Answer

Answer: A, D

Explanation:

Flexible NetFlow allows for more efficient use of resources by sampling packets rather than analyzing every single one. This means that only a subset of traffic is selected randomly, which reduces the number of packets to be analyzed (D) and consequently lowers CPU and memory utilization (A).
