Which three items should be validated prior to installing ESXi 6.x? (Choose three.)
The correct answer is A. Remote Storage has been disconnected. B. Installation media is available. C. Server hardware clock is set to UTC. Before installing ESXi 6.x, administrators must confirm that remote storage is disconnected to avoid accidental overwrites, that installation media is present, and that the hardware clock is set to UTC for accurate timekeeping.

Why each option
Before installing ESXi 6.x, administrators must confirm that remote storage is disconnected to avoid accidental overwrites, that installation media is present, and that the hardware clock is set to UTC for accurate timekeeping.
Remote storage devices (SAN LUNs, iSCSI targets) should be disconnected before installation to prevent the ESXi installer from presenting them as potential install targets and to avoid accidental data loss on production storage.
Installation media (ISO, USB drive, or PXE configuration) must be available and accessible before the installation process can begin - this is a fundamental prerequisite.
ESXi relies on the hardware clock being set to UTC so that the hypervisor and its guests can correctly calculate local times using time zone offsets, and an incorrect clock can cause certificate errors, log inconsistencies, and licensing issues.
ESXi creates and manages its own VMFS partitions during installation; pre-partitioning storage with VMFS is not required and the installer will overwrite any existing partition table on the selected device.
Jumbo frames (MTU 9000) are an optional network optimization configured after installation and are not a prerequisite for successfully installing ESXi.
