A company has AOS-CX switches and HPE Aruba Networking APs, which run AOS-10 and bridge...

802.1X Authentication Modes:

Client Auth-Mode: Requires each connected endpoint to authenticate individually using 802.1X.

Device Auth-Mode: Allows the port to authenticate a device, such as an AP, as a whole. This mode works when the device bridges traffic (e.g., AP bridging SSID traffic).

AP Role Configuration:

Since the AP bridges traffic from multiple clients, you must configure the AP role to use device auth-mode.

Meanwhile, the ports on edge switches can remain in client auth-mode to enforce 802.1X for individual client connections.

Option Analysis:

Option A: Correct. This ensures the AP itself authenticates with device auth-mode, while edge ports remain in client auth-mode.

Option B: Incorrect. APs require device auth-mode for bridging, not client auth-mode.

Option C: Incorrect. Device auth-mode on all ports would not meet the security policy for clients.

Option D: Incorrect. Leaving all ports in device auth-mode does not meet the policy for 802.1X on edge ports.
