Exam HPE6-A45 topic 1 question 137 discussion

Actual exam question from HP's HPE6-A45

Question #: 137
Topic #: 1

AOS-Switches authenticate guests to ClearPass with captive portal. When guests first connect their device to the network, they are redirected to a captive portal in which they log in. ClearPass then stores the guest MAC addresses, and the guests are permitted access. Due to a conflict, the network administrator needs to change the dynamic authorization port, port 3799 on Aruba ClearPass.
If the administrator forgets to also change the port on one of the AOS-Switches, what will be one symptom?

A. Some guests receive full access to the network when they first connect instead of being redirected to the portal page
B. When some guests successfully authenticate in the captive portal, they are redirected back to the portal page
C. Guests are redirected to the system listening on port 3799
D. Some guests are unable to reach the captive portal page. Instead, they receive no access at all

The correct answer is "B". It is important that the switch is set up to accept this message. You must enable dynamic authorization when you specify ClearPass as the RADIUS server, and you must make sure that the port is correct. The default dynamic authorization port on both AOS-Switches and ClearPass is 3799. (If the switch does not accept the CoA message, the client will not reauthenticate).
