Which two considerations should an administrator keep in mind when booting from Software Fiber Channel over Ethernet (FCoE)? (Choose two.)
The correct answer is C. Multipathing is not supported at pre-boot. D. Boot LUN cannot be shared with other hosts even on shared storage. When booting from Software FCoE, administrators must account for single-path limitations at pre-boot and the restriction that the boot LUN cannot be shared among hosts.

Why each option
When booting from Software FCoE, administrators must account for single-path limitations at pre-boot and the restriction that the boot LUN cannot be shared among hosts.
Software FCoE boot settings must be configured at the firmware/BIOS level before ESXi loads; these settings cannot be modified from within a running ESXi instance.
Software FCoE boot firmware can export boot configuration data in FBFT (FCoE Boot Firmware Table) format, making this statement false.
During the pre-boot phase (BIOS/UEFI firmware initialization), multipathing software has not yet loaded, so only a single path to the boot LUN is available, which is a fundamental limitation of software FCoE boot.
The boot LUN used for Software FCoE boot must be dedicated to a single host - even if it resides on shared storage hardware, presenting the same boot LUN to multiple hosts risks data corruption and is explicitly unsupported.
