Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 809

When should the MAC authentication bypass feature be used on a switch port?

Answer options

• A. when the attached host supports 802.1X and must authenticate itself based on its MAC address instead of user credentials
• B. when the attached host supports limited 802.1X
• C. when authentication is required, but the attached host does not support 802.1X
• D. when authentication should be bypassed for select hosts based on their MAC address

Correct answer: C

Explanation

The correct answer is C because MAC authentication bypass is specifically used when a device cannot support 802.1X but still needs to be authenticated. Options A and B are incorrect as they pertain to scenarios where 802.1X is supported. Option D is also incorrect because it suggests bypassing authentication, which is not the intended purpose of this feature.
