By correlating these events, it provides administrators with a clear view of systemic issues affecting site-wide uptime rather than just showing isolated hardware alerts.

NEW QUESTION 46
Which feature is only available with an AOS10 Advanced AP license, not with a Foundation license?

UCC visibility

Live upgrades

AI insights

UCC (Unified Communications and Collaboration) visibility is an advanced analytics feature available only with the AOS10 Advanced AP license. It provides deeper application-level insights into voice and video performance, which is not included in the Foundation license set.

NEW QUESTION 47
You are creating a new WPA3-Enterprise SSID. What is required to complete the configuration?

Primary authentication server

VLAN assignment Rules

WPA3 Transition Mode

WPA3-Enterprise requires integration with an external authentication mechanism such as a RADIUS server to validate user credentials. Defining a primary authentication server is essential to enable secure 802.1X-based authentication for clients connecting to the SSID.

NEW QUESTION 48
