Show answer & explanation
Correct answer: B
HPE Aruba Networking Central API uses OAuth 2.0. Access Tokens are short-lived (default 2 hours). When they expire, a 401 error occurs. The correct automated resolution is for the script to catch this error and use the long-lived Refresh Token to request a new Access Token seamlessly.

Network Management with HPE Aruba Networking Central · Monitoring
A retail company has deployed AOS-10 APs across 50 stores. Recently, store managers have complained that the Point of Sale (POS) tablets are losing connection to the inventory database during peak hours.
The network administrator investigates and suspects that guest users are consuming excessive bandwidth by streaming high-definition video on the guest SSID, starving the corporate applications of necessary resources.
The administrator needs to verify this suspicion and then implement a solution that restricts video streaming bandwidth without completely blocking the guest network.
Which combination of HPE Aruba Networking Central tools should be used to resolve this issue?
Show answer & explanation
Correct answer: C
AppRF provides deep packet inspection to identify and monitor specific applications and web categories. The administrator can use this visibility to confirm the high video streaming usage, and then leverage role-based policies to apply a bandwidth contract (rate-limit) specifically to that application category for the guest role.
