Palo Alto Networks Cybersecurity Entry-Level Technician (PCCET) — Question 52

What differentiates knowledge-based systems from behavior-based systems?

Answer options

• A. Behavior-based systems find the data that knowledge-based systems store.
• B. Knowledge-based systems pull from a previously stored database that distinguishes “bad”.
• C. Knowledge-based systems try to find new, distinct traits to find “bad” things.
• D. Behavior-based systems pull from a previously stored database that distinguishes “bad”.

Correct answer: B

Explanation

The correct answer is B because knowledge-based systems rely on a database of known 'bad' characteristics to make decisions. Options A and D mischaracterize the role of behavior-based systems, while option C inaccurately describes knowledge-based systems as those that seek out new traits rather than relying on established databases.
