JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2021) — Question 34

You want to set up JSA to collect network traffic flows from network devices on your network.
Which two statements are correct when performing this task? (Choose two.)

Answer options

• A. BGP FlowSpec is used to collect traffic flows from Junos OS devices.
• B. Statistical sampling increases processor utilization.
• C. Statistical sampling decreases event correlation accuracy.
• D. Superflows reduce traffic licensing requirements.

Correct answer: C, D

Explanation

Option C is correct because statistical sampling can lead to a loss of detail in the data, thus reducing the accuracy of event correlation. Option D is also correct as superflows can consolidate multiple flows into a single flow, which can minimize the licensing needed for processing traffic. Options A and B are inaccurate because BGP FlowSpec is specific to Junos OS devices and statistical sampling does not inherently increase processor utilization.
