While navigating HPE Aruba Networking Central, an administrator needs to investigate a specific user's laptop that is reporting a poor Wi-Fi experience. Where in the Central UI should the administrator navigate to view the Client Health score and connection history for this specific device?
Show answer details
Correct answer: B
To view detailed information about a specific client, including its Client Health score, connection history, and data path, the administrator should navigate to the Clients tab (either at the Global, Group, or Site context) and select the specific client's MAC/IP address to open the Client Details page.

A managed service provider (MSP) uses HPE Aruba Networking Central to manage multiple customer networks. The MSP recently hired a junior technician who should only be allowed to view and monitor the network for 'Customer A', which is mapped to a specific Site in Central. The technician must not be able to make configuration changes or view any other customer's data.
Which administrative configuration achieves this requirement?
Show answer details
Correct answer: A
HPE Aruba Networking Central supports scoped access through Resource Restrictions. By combining a custom Role-Based Access Control (RBAC) role (e.g., View Only) with a Resource Restriction policy tied to a specific Site or Group, the technician is strictly limited to viewing only the permitted customer's environment.

When configuring a custom Captive Portal for guest Wi-Fi access in HPE Aruba Networking Central, an administrator needs to ensure that users do not receive security warnings in their web browsers. Which action must the administrator perform in the Central administration settings?
Show answer details
Correct answer: A
To prevent browser security warnings when guests are redirected to a Captive Portal over HTTPS, the portal must present a valid SSL/TLS certificate signed by a public CA that the client devices already trust. This certificate is uploaded and managed via Central's Certificate Management.

An enterprise organization is migrating its campus network management to HPE Aruba Networking Central. The architect needs to define a configuration hierarchy that allows global baseline settings for all switches, while permitting regional administrators to apply specific VLAN and security policies to switches in their respective geographic areas. Which architectural approach represents the best practice for this requirement?
Show answer details
Correct answer: C
HPE Aruba Networking Central supports a multi-tier configuration hierarchy (Global > Group > Device). Best practice for this scenario is to apply the common baseline settings at the Global level, which inherit down, and then use Groups for regional specifics. Sites are primarily for monitoring and reporting, not for configuration overrides.

A network administrator is evaluating the AI Insights feature within HPE Aruba Networking Central to improve proactive troubleshooting. Which TWO capabilities are natively provided by AI Insights to assist in network optimization? (Select TWO)
Show answer details
Correct answer: B, C
AI Insights uses AIOps to analyze telemetry data. It can detect STP anomalies (such as rapid topology changes) and provide actionable recommendations. It also analyzes Wi-Fi environments to recommend or automatically apply channel/power optimizations via AirMatch. It does not automatically execute firmware upgrades or deploy new VRFs without admin intervention.

A global financial institution is integrating its custom IT Service Management (ITSM) platform with HPE Aruba Networking Central to automate incident creation when network devices go offline.
The development team needs to authenticate their application using the REST API. They require a method that allows their backend script to maintain long-term access without manual intervention, while strictly limiting the script's capabilities to read-only monitoring data. The security team mandates that the integration must follow least-privilege principles and use standard OAuth 2.0 flows supported by the Developer Hub.
Which combination of actions should the network architect take to securely enable this integration?

Correct answer: B
To adhere to least-privilege, a custom RBAC role must be created that limits access to read-only monitoring. The script must use the OAuth 2.0 flow, which involves a short-lived Access Token and a long-lived Refresh Token. The script uses the Refresh Token to programmatically request new Access Tokens when they expire, enabling long-term, secure, automated access without manual intervention.
