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.
