Implementing Cisco Network Security (IINS, legacy) — Question 3

What is the Cisco preferred countermeasure to mitigate CAM overflows?

Answer options

• A. Port security
• B. Dynamic port security
• C. IP source guard
• D. Root guard

Correct answer: B

Explanation

Dynamic port security is the preferred method because it allows for the dynamic management of MAC addresses on a switch port, helping to mitigate issues like CAM overflow. Port security can be effective but lacks the dynamic capabilities, while IP source guard and root guard serve different purposes in network security.
