HPE Aruba Certified Campus Access Expert (ACAEX) — Question 7

You are setting up a customer’s 150 headless IoT devices that do not support 802.1X.
What should you use?

Answer options

• A. Multiple Pre-Shared Keys (MPSK) Local
• B. HPE Aruba Networking ClearPass profiling with WPA-PSK
• C. HPE Aruba Networking ClearPass profiling with MAC-AUTH
• D. Multiple Pre-Shared Keys (MPSK) with WPA3-AES

Correct answer: A

Explanation

The correct answer, A, Multiple Pre-Shared Keys (MPSK) Local, is suitable for devices that cannot authenticate using 802.1X. The other options involve methods requiring additional infrastructure or protocols not compatible with headless IoT devices, such as WPA-PSK and MAC-AUTH, which are not appropriate for this scenario.
