Which file type must be downloaded from the Nutanix Portal for NDB deployment?

For deploying Nutanix Database Service (NDB), the required file type to download from the Nutanix Portal is an OVA (Open Virtual Appliance) file. The OVA format is a standardized package that includes a pre-configured virtual machine image, including the NDB software, which can be imported into supported hypervisors (e.g., VMware ESXi or Nutanix AHV). This simplifies the deployment process by providing a ready-to-use VM template with all necessary components.

Option A (ZIP) is incorrect as ZIP files are generic archives, not deployment-specific formats for NDB.

Option B (QCOW2) is incorrect because QCOW2 is a disk image format primarily used with KVM/QEMU, not the standard for NDB deployment.

Option C (OVA) is correct as it is the official file type provided by Nutanix for NDB deployment.

Option D (TAR) is incorrect as TAR files are used for archiving, not as a deployment package for NDB.

Administrators should download the OVA from the Nutanix Portal and follow the deployment guide.
