To ensure an NDB server can send periodic telemetry data to the central Nutanix repository, the server must be able to communicate with the Nutanix Insights platform over port 443 (HTTPS). The insights.nutanix.com site is the designated endpoint for telemetry data, which includes usage statistics, health metrics, and other operational data sent to Nutanix for support and analytics purposes. This connectivity is a standard requirement for NDB to comply with Nutanix's telemetry and support framework, and port 443 is used for secure transmission.
* Option A (download.nutanix.com) is incorrect because this site is used for downloading software updates, not telemetry data.
* Option B (developers.nutanix.com) is incorrect as it is a resource for developers, not a telemetry endpoint.
* Option C (portal.nutanix.com) is incorrect because this is the Nutanix customer portal for account management, not telemetry submission.
* Option D (insights.nutanix.com) is correct as it is the specific site for sending telemetry data.
The administrator should ensure network policies allow outbound traffic to this site on port 443.
