Explanation:
a) Alerts on config changes via email - Foundation
b) Group-based firmware compliance - Foundation
c) Heat maps of deployed APs - Advanced
d) Live upgrades of an AOS10 cluster - Advanced
According to the Aruba Central Licensing Guide1, the Foundation License provides basic device management features such as configuration, monitoring, alerts, reports, firmware management, etc. The Advanced License provides additional features such as AI insights, WLAN services, NetConductor Fabric, heat maps, live upgrades, etc.

OSPF Open Shortest Path First. OSPF is a link-state routing protocol that uses a hierarchical structure to create a routing topology for IP networks. OSPF routers exchange routing information with their neighbors using Hello packets, which are sent periodically on each interface. To establish an adjacency Adjacency is a relationship formed between selected neighboring routers for the purpose of exchanging routing information., OSPF routers must agree on several parameters, including Hello timers, which specify how often Hello packets are sent on an interface. If the Hello timers do not match between neighboring routers, they will not form an adjacency and will not exchange routes.

The client's broadcast domain in ArubaOS can be set with role-based VLAN overrides within the firewall role settings. This allows for dynamic assignment of VLANs to users based on their role, which determines their level of network access, including their broadcast domain.

In the access tracker of ClearPass, after a customer successfully connects to a guest network through a captive portal, the OUTPUT tab should show a role indicating that the user is authenticated, such as
"Guest authenticated." This role confirms that the user has passed the authentication process and has been granted access.

Bonding multiple 20MHz wide 802.11 channels is a technique to create a wider bandwidth channel that supports higher data rate transmissions. It can increase the throughput between the client and AP by using more spectrum resources and reducing interference.
