A systems administrator needs to install a new server OS on a virtual machine (VM) located on a hypervisor in a remote data center. The administrator has already uploaded the OS installation ISO file to a datastore that is accessible by the hypervisor. Which of the following is the MOST efficient method to begin the OS installation?
Use a network file transfer utility to copy the ISO file directly to the VM's unformatted virtual hard disk.
Enable USB pass-through on the hypervisor to connect a bootable flash drive to the VM.
Use the remote console to map the VM's CD/DVD drive to a physical drive on the administrator's local workstation.
Configure the VM's settings to connect the virtual CD/DVD drive to the ISO file located on the datastore.
The correct option is to configure the VM's settings to connect its virtual CD/DVD drive directly to the ISO file on the datastore. This is the most efficient and standard method because the hypervisor reads the installation file from its high-speed storage network and presents it to the VM as a bootable device. Using a remote console to map a local workstation drive is inefficient as it streams the entire installation over the WAN/LAN connection from the administrator's machine. USB pass-through is not typically supported for booting a new OS installation and requires managing physical devices on the host. It is impossible to copy an ISO file to the VM's virtual hard disk before an OS is installed, as the disk is unformatted and not accessible over the network.
