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

To deploy the NDB virtual appliance on a VMware ESXi hypervisor, the administrator must download the Open Virtualization Appliance (OVA) file from the Nutanix Portal. An OVA file is a package that contains all the necessary components for the virtual appliance, including the virtual disk image (VMDK) and the virtual machine configuration file (OVF). This allows for a simple and standardized deployment process through the vSphere Client's "Deploy OVF Template" wizard.

A. A ZIP file is a generic archive format and is not the specific appliance format provided for NDB deployment.
B. The QCOW2 file format is the virtual disk image used for deploying the NDB appliance on the Nutanix AHV hypervisor, not on VMware ESXi.
D. A TAR file is a generic archive format and is not the specific appliance format provided for NDB deployment.
