Which two statements are true regarding upgrading ESXi 6.x hosts using a USB flash drive? (Choose two.)

The correct answer is B. The USB flash drive must be formatted using Fat32. C. A partition table must be manually created on the USB flash device.. Creating a bootable USB flash drive for ESXi installation requires FAT32 formatting so the BIOS/UEFI bootloader can read it, and a partition table must be manually created on the device before writing the installer image.

Why each option

Creating a bootable USB flash drive for ESXi installation requires FAT32 formatting so the BIOS/UEFI bootloader can read it, and a partition table must be manually created on the device before writing the installer image.

AThe ks.cfg file must be available to the ESXi 6.x host during bootup on a TFTP server.

The ks.cfg kickstart file does not have to reside on a TFTP server - it can be placed directly on the USB drive itself, or hosted on HTTP, FTP, NFS, or CDROM sources.

BThe USB flash drive must be formatted using Fat32.Correct

The USB flash drive must be formatted as FAT32 because the ESXi bootloader and SYSLINUX require a FAT32 filesystem to be recognized and executed during the BIOS/UEFI boot process.

CA partition table must be manually created on the USB flash device.Correct

A partition table (MBR) must be manually created on the USB device using a tool such as fdisk or a disk partitioning utility before the filesystem can be formatted and the bootloader installed.

DThe USB flash drive must be mounted from a Windows device with sysconfig installed.

There is no requirement to mount the USB flash drive from a Windows device with 'sysconfig' installed - the process can be performed from Linux using tools like dd and fdisk, or from Windows using other utilities.
