CompTIA Network+ (N10-007) — Question 113

Which of the following security mechanisms dynamically assigns a Layer 2 address and restricts traffic only to that Layer 2 address?

Answer options

• A. Sticky MAC
• B. 802.1x
• C. ACL
• D. NAC

Correct answer: A

Explanation

The correct answer is A, Sticky MAC, as it allows the dynamic assignment of MAC addresses to ports and restricts traffic to only those assigned MAC addresses. Option B, 802.1x, is an authentication protocol, while C, ACL, refers to access control lists that filter traffic based on IP or Layer 3 information. Option D, NAC, stands for Network Access Control, which encompasses broader security measures but does not specifically deal with dynamic Layer 2 address assignments.
