CCNA Routing and Switching (legacy) — Question 170

By default, how many MAC addresses are permitted to be learned on a switch port with port security enabled?

Answer options

• A. 8
• B. 2
• C. 1
• D. 0

Correct answer: C

Explanation

The correct answer is C, as the default setting for port security on Cisco switches allows only one MAC address to be learned per port. Options A and B are incorrect because they exceed the default limit, and option D is incorrect as it implies that no MAC addresses can be learned, which is not the case.
