JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2021) — Question 10

Which two statements are correct when considering IPS rule base evaluation? (Choose two.)

Answer options

• A. IPS evaluates rules concurrently.
• B. IPS applies the most severe action to traffic matching multiple rules.
• C. IPS evaluates rules sequentially.
• D. IPS applies the least severe action to traffic matching multiple rules.

Correct answer: B, C

Explanation

The correct answers are B and C because IPS prioritizes the most severe action when traffic matches multiple rules, ensuring that the most impactful response is enacted. Additionally, IPS evaluates rules sequentially, meaning it processes each rule one after the other rather than simultaneously. Options A and D are incorrect as they misrepresent the evaluation process and the action severity applied.
