Selected Answer: C
OK it´s weird Question and Answers, but im going with C. Why not B? Because MAC address learning doesn´t directly increase security on the management VLAN. While MAC address learning is crucial for proper network operation, it does not inherently enhance security on the management VLAN. Security on the management VLAN is typically enforced through other means, such as access control lists (ACLs), VLAN segmentation, authentication mechanisms, encryption protocols, and strict management policies.

a few weeks ago when i was lab configuring on udemy courses, theres a part where you can enable how many mac addresses can be learnt at max and if you exceed the max a violation occurs and this shuts off the interface. I forgot what i was called it may be a syslog but this is why i went with be because that is a key function. Also i work ona military base and this is their setup becuase they do not want unknown devices on their network.

Answers A and C negates each other and are not functions. Answer D states a threat and is therefore obviously incorrect. That leaves us with B, which is an actual function.

By default, MAC address learning is enabled on all interfaces and VLANs on the router. https://content.cisco.com/chapter.sjs?uri=/searchable/chapter/www.cisco.com/content/en/us/td/docs/wireless/mwr_2941_dc/software_config/guide/3_5_1/2941_351_ConfigGuide/mac_lrn.html.xml#:~:text=By%20default%2C%20MAC%20address%20learning,VLANs%20can%20learn%20MAC%20addresses.
