HPE Aruba Certified Mobility Professional (ACMP) — Question 87

What is a typical reason to implement MAC authentication on an AOS-Switch?

Answer options

• A. to filter traffic at the edge, based on multiple criteria in the MAC header
• B. to provision switch ports to support devices such as IP phones or printers
• C. to enhance the security of an 802.1X solution
• D. to control management access to the switch CLI based on device, as well as user credentials

Correct answer: C

Explanation

The correct answer is C because MAC authentication improves the security of an 802.1X deployment by ensuring that only authorized devices can connect to the network. The other options, while relevant to network management, do not specifically address the security enhancements provided by MAC authentication in an 802.1X context.
