Cisco Exam 200-201 Topic 2 Question 88 Discussion

Actual exam question for Cisco's 200-201 exam

Question #: 88
Topic #: 2

How low does rule-based detection differ from behavioral detection?

ABehavioral systems find sequences that match particular attach behaviors, and rule-based systems identify potential zero-day attacks.

BRule-based systems search for patterns linked to specific types of attacks, and behavioral systems Identify attacks per signature.

CBehavioral systems have patterns are for complex environments, and rule-based systems can be used on low-mid-sized businesses.

DRule-based systems have predefined patterns, and behavioral systems learn the patterns that are specific to the environment.

Show Suggested Answer

Suggested Answer: D

Rule-based detection systems operate using predefined patterns and signatures to identify known threats. These patterns are based on prior knowledge of attack methods and vulnerabilities.

Behavioral detection systems, on the other hand, analyze the normal behavior of a network or system to establish a baseline. They then monitor for deviations from this baseline, which may indicate potential threats.

Rule-based systems are effective at detecting known threats but may struggle with novel or zero-day attacks that do not match existing signatures.

Behavioral systems can detect unknown threats by recognizing abnormal activities, making them useful in identifying zero-day exploits and other sophisticated attacks.

Option D, all the way! It's like the difference between a chef following a recipe and a master chef creating their own signature dish. The predefined patterns versus the learned patterns - that's the key distinction here.

Haha, this is a classic 'spot the difference' type of question. I'm leaning towards D, but I'm also a little curious about C - the idea of rule-based systems being more suitable for smaller businesses is an interesting angle to consider.

I see your point, but C also makes sense with rule-based systems being used for smaller businesses.

I think D is correct, rule-based systems have predefined patterns.

Wow, really thought-provoking question! I'm torn between A and D, but I think D captures the essence of the difference a bit better. Rule-based and behavioral are like oil and water - they just work in different ways.

I'm going with B. The description of rule-based systems searching for attack patterns and behavioral systems using signatures aligns with my understanding of the two approaches.

Option D seems to be the most comprehensive explanation of the difference between rule-based and behavioral detection. The predefined patterns in rule-based systems and the learning capabilities of behavioral systems make sense.
