Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 218

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
What are two results of implementing this feature instead of traditional NetFlow? (Choose two.)

Answer options

• A. Only the flows of top 100 talkers are exported.
• B. CPU and memory utilization are reduced.
• C. The number of packets to be analyzed are reduced.
• D. The data export flow is more secure.
• E. The accuracy of the data to be analyzed is improved.

Correct answer: B, C

Explanation

The correct answers are B and C because using a random sampling method reduces the overall amount of data processed, thereby lowering CPU and memory usage, as well as decreasing the number of packets analyzed. The other options are incorrect as they either pertain to security or data accuracy, which are not direct benefits of implementing Flexible NetFlow sampling.
