HPE6-A90 sample questions

Question 1

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)

Accepted Answer

Detecting Spanning Tree Protocol (STP) anomalies and recommending topology fixes.

Accepted Answer

Identifying suboptimal RF environments and recommending channel or power adjustments.

Answer

Automatically executing firmware upgrades on AOS-CX switches when a CVE is detected.

Answer

Dynamically deploying new VRFs to segment traffic when anomalous bandwidth usage is detected.

Answer

Generating custom Python scripts for zero-touch provisioning of branch gateways.

Question 2

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?

D --> F[Read Monitoring Data]
```

Accepted Answer

Create a custom RBAC role with 'View Only' permissions for Monitoring. Assign this role to an API user, generate an Access Token and a Refresh Token in the Developer Hub, and program the script to use the Refresh Token to periodically obtain new Access Tokens.

Answer

Create a new API Gateway user with Super Administrator privileges. Generate a static API key in the Developer Hub and hardcode it into the ITSM script for permanent access.

Answer

Use the default Network Operations role. Generate a long-lived Access Token (set expiration to 10 years) in the Developer Hub and apply a Resource Restriction policy limiting the token to the ITSM server's IP address.

Answer

Configure a Webhook to push read-only data to the ITSM platform, bypassing the need for REST API tokens, and apply an Identity-based firewall policy to restrict write access.

Question 3

HPE Aruba Networking Central is accessed and managed entirely as an application within the broader HPE GreenLake cloud platform architecture.

Accepted Answer

True

Answer

False

Question 4

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?

Accepted Answer

Floor Plan Manager

Answer

Topology View

Answer

AirMatch Dashboard

Answer

AI Insights Recommender

Question 5

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?

Accepted Answer

The Access Token has expired. The script must use the Refresh Token to call the API endpoint for token renewal to obtain a new Access Token.

Answer

The Refresh Token has expired. The script must prompt the user to manually log into the Developer Hub to generate a new token pair.

Answer

The API rate limit has been exceeded. The script must implement an exponential backoff algorithm and wait 24 hours before retrying.

Answer

The Developer Hub certificate has been revoked. The script must download and install the latest CA chain from the HPE GreenLake portal.

Question 6

A critical configuration change was made to an AOS-CX switch via HPE Aruba Networking Central, which inadvertently caused a network outage. The IT director wants to know exactly who made the change, when it was made, and what the previous configuration was. Which feature in Central provides this information?

Accepted Answer

Audit Trail

Answer

AI Insights

Answer

Alerts and Notifications

Answer

Network Topology
