How can you enable a VM to boot from a remote datastore?

Enabling a virtual machine (VM) to boot from a remote datastore involves configuring the VM to access storage solutions that are capable of providing boot capabilities over the network. In this case, using a bootable iSCSI or NFS datastore achieves this.

iSCSI (Internet Small Computer Systems Interface) allows SCSI commands to be sent over a network, enabling VMs to connect to and boot from a remote storage system. NFS (Network File System), on the other hand, allows VMs to access files on a networked location, enabling the VM to boot from a remote data store where its files are staged. Both of these technology approaches leverage network infrastructure to extend the storage capabilities beyond the local machine, allowing for flexibility and scalability in virtual environment management.

Other options do not provide the necessary method and capability to boot a VM from a remote datastore. For example, setting the VM's BIOS to legacy mode, attaching a local disk, or mandating direct attached storage only are not methods that facilitate booting from networked storage solutions. They typically restrict or do not utilize remote resources necessary for boot processes in a VMware vSphere environment. Therefore, configuring the VM to use a remote iSCSI or NFS datastore is the correct
