Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) — Question 197
What is the difference between deep packet inspection and stateful inspection?
Answer options
- A. Stateful inspection is more secure due to its complex signatures, and deep packet inspection requires less human intervention.
- B. Deep packet inspection is more secure due to its complex signatures, and stateful inspection requires less human intervention.
- C. Deep packet inspection gives insights up to Layer 7, and stateful inspection gives insights only up to Layer 4.
- D. Stateful inspection verifies data at the transport layer, and deep packet inspection verifies data at the application layer.
Correct answer: C
Explanation
The correct answer is C because deep packet inspection analyzes data all the way to Layer 7, allowing for a thorough examination of the content. In contrast, stateful inspection operates only up to Layer 4, focusing on the transport layer and connection states. The other options incorrectly attribute security levels and human intervention needs to the two inspection methods.
