Network Management with HPE Aruba Networking Central · HPE Aruba Networking Central architecture
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?
Answer and explanation
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.

Network Management with HPE Aruba Networking Central · Troubleshooting
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)
Answer and explanation
Correct answers: 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.

Network Management with HPE Aruba Networking Central · HPE Aruba Networking Central API capability
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?

B -->|2. Validate Credentials| C{Token Type}
C -->|Access Token| D[Short-lived API Access]
C -->|Refresh Token| E[Generate New Access Token]
D --> F[Read Monitoring Data]
Answer and explanation
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.

Network Management with HPE Aruba Networking Central · Floor Plan Manager and topology
A wireless engineer is planning to upgrade the access points in a large office building. They need to visualize the current RF coverage and identify potential dead zones before deploying new AOS-10 APs. Which HPE Aruba Networking Central feature provides a visual heat map of the RF environment based on AP placement?
Answer and explanation
Correct answer: C
The Floor Plan Manager in HPE Aruba Networking Central allows administrators to upload building floor plans, place APs, and view RF heat maps to assess coverage and plan WLAN deployments.

Network Management with HPE Aruba Networking Central · HPE Aruba Networking Central API capability
An automation script interacting with the HPE Aruba Networking Central REST API suddenly stops working after running successfully for two hours. The developer checks the logs and sees a '401 Unauthorized' error. What is the most likely cause and the appropriate programmatic resolution?
Answer and 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.
