Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 120

Why the network administration can want to disable MAC address learning on the router?

Answer options

• A. To free up space in MAC address table.
• B. To use space in MAC address table
• C. To wipe space in MAC address table.
• D. There was a security violation.

Correct answer: A

Explanation

Disabling MAC address learning can help in freeing up space in the MAC address table, which is essential when the table is nearing its limit. Options B and C imply using or clearing space but do not address the need to free up space specifically. Option D suggests a security issue, which is not the primary reason for disabling MAC address learning.
