Answer: ADE

Explanation:

MAC Move Limiting:

MAC move limiting is a security feature used in network switches to detect and mitigate rapid changes in MAC address locations, which could indicate a network issue or an attack such as MAC flapping or spoofing.

When a MAC address is learned on a different interface than it was previously learned, the switch can take various actions to prevent potential issues.

Available Actions:

A. drop: This action drops packets from the MAC address if it violates the move limit, effectively blocking communication from the offending MAC address.

D. log: This action logs the MAC move event without disrupting traffic, allowing network administrators to monitor and investigate the event.

E. shutdown: This action shuts down the interface on which the MAC address violation occurred, effectively stopping all traffic on that interface to prevent further issues. Other Actions (Not Correct):

B. filter: Filtering is not typically associated with MAC move limiting; it generally refers to applying ACLs or other mechanisms to filter traffic.

C. enable: This is not an action related to MAC move limiting, as it does not represent a specific

reaction to a MAC move event.

Reference: MAC move limiting is crucial for maintaining network stability and security, particularly in environments with dynamic or large-scale Layer 2 networks where MAC addresses might frequently change locations.
