Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) — Question 49

What is the difference between deep packet inspection and stateful inspection?

Answer options

• A. Deep packet inspection is more secure than stateful inspection on Layer 4
• B. Stateful inspection verifies contents at Layer 4 and deep packet inspection verifies connection at Layer 7
• C. Stateful inspection is more secure than deep packet inspection on Layer 7
• D. Deep packet inspection allows visibility on Layer 7 and stateful inspection allows visibility on Layer 4

Correct answer: D

Explanation

The correct answer is D because deep packet inspection operates at Layer 7, allowing for a detailed analysis of the packet's content, while stateful inspection operates at Layer 4, focusing on the connection state and not the packet's content. Options A, B, and C incorrectly describe the security levels and the layers at which these inspections operate.
