What are three actions available tor MAC move limiting? (Choose three.)
A.
drop
B.
filter
C.
enable
D.
log
E.
shutdown
The Answer Is:
A, D, E
This question includes an explanation.
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.
Data Center References:
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.
