For security reasons, the Nutanix AI platform displays an API key only once at the time of its creation. The platform does not store the secret key in a retrievable format. If an API key is lost after the creation dialog is closed, it cannot be recovered by any means, including through the dashboard or by contacting support. The only valid procedure is to generate a new key. This is typically done by deleting the existing endpoint and creating a new one, which will provide a new, unique API key to be used for authentication.

A. Nutanix Support does not have access to customer-specific secret credentials like API keys for security and privacy reasons, and therefore cannot recover them.

C. The term "reset" is inaccurate. A completely new and distinct key must be generated; the old key is not modified or reset but is replaced entirely.

D. The NAI Dashboard does not store or display the secret portion of the API key after its initial creation to prevent security vulnerabilities.

This section explicitly states: "The Create Endpoint dialog box displays the API key. Copy the API key and store it in a secure location. You cannot view the key again after you close this dialog box." This confirms that the key is not retrievable after creation, invalidating options A and D.

2. Nutanix GPT-in-a-Box 2.0 User and Administration Guide, Chapter: "Managing Endpoints", Section: "Deleting an Endpoint".

This section outlines the procedure for removing an endpoint. If a key is lost or compromised, the standard security practice is to delete the associated endpoint and create a new one, which generates a new key. This supports the answer that a new key must be generated (B).
