HPE Aruba Certified Mobility Professional (ACMP) — Question 39

Which situation requires an AOS-Switch interface to support MAC-based VLANs?

Answer options

• A. The interface has an extended MAC ACL applied to it in the outbound direction, and it uses VLAN ID as one of the criteria for rules.
• B. The interface has an extended MAC ACL applied to it in the inbound direction, and it has multiple tagged VLAN assignments.
• C. The interface is configured to support Local MAC Authentication (LMA), authenticates endpoints against a non-default MAC group, and limits the address count to 1.
• D. The interface is configured to support 802.1X in user-based mode, connects to more than one endpoint at a time, and users are assigned to different dynamic VLANs.

Correct answer: B

Explanation

Option B is correct because it describes a situation where the interface must manage multiple tagged VLANs, necessitating MAC-based VLAN support. Options A, C, and D do not require this feature; A deals with outbound ACLs, C is focused on Local MAC Authentication with a single address, and D involves 802.1X which does not specifically necessitate MAC-based VLANs.
