Exam HPE6-A73 topic 1 question 100 discussion

Actual exam question from HP's HPE6-A73

Question #: 100
Topic #: 1

The company has just upgraded their access layer switches with AOS-CX switches and implemented an AAA solution with ClearPass. The company has become concerned about what actually connects to the user ports on the access layer switch, Therefore, the company is implementing 802.1X authentication on the AOS-
CX switches. An administrator has globally enabled 802.1X, and has enabled it on all the access ports connected to user devices, including VoIP phones, security cameras, and wireless Aruba IAPs. Wireless users are complaining that they successfully authenticate to the IAPs; however, they do not have access to network resources. Previously, this worked before 802.1X was implemented on the AOS-CX switches.
What should the company do to solve this problem?

A. Implement device-based mode on the IAP-connected AOS-CX switch ports.
B. Implement local user roles and local forwarding on the AOS-CX switches.
C. Implement downloadable user roles and user-based tunneling (UBT) on the AOS-CX switches.
D. Implement AAA RADIUS change of authorization on the AOS-CX switches.

Answer is A. C is not correct, because customer doesnt have MC, only has IAP. Here is the detail explaination from SG: The IAP itself is responsible to handle the authentication, so it would perform 802.1X authentication with the wireless clients. But then the traffic is forwarded as regular traffic on the switch port, so the switch would also attempt to perform authentication of this client. Since the 802.1X traffic of the client is terminated at the IAP, the switch would attempt to perform MAC authentication for the client MAC address. This is unnecessary and confusing, since ClearPass would see the same MAC address as 802.1X authenticated on the IAP, and MAC-authenticated on the switch port. For this scenario, the switch can be set to ‘port-based’ authentication; that is, device mode.
