Question1: What is one difference between captive portal authentication and 802.1X authentication?

Question2: A WLAN in an Aruba Mobility Master (MM)-based solution uses WPA2-Enterprise security.

Question5: How does WPA2 protect wireless user traffic in the air?

Question6: A network administrator creates the role employees and adds the rule to it:
user any any permit
The first several wireless clients assigned to the employees role are assigned IP addresses in the
10.10.10.0/24 subnet. Several other wireless clients with the employees role are then assigned IP addresses in the 10.10.20.0/24.
When the Aruba firewall mathces traffic from these clients to the user any any permitrule, what does it do?

Question7: A company has a single Aruba Mobility Master (MM)-based solution with two Mobility Controllers (MCs).
