Which two statements are true regarding a new vSphere deployment that is using software FCoE boot from SAN? (Choose two.)
A. Multi-pathing options must be configured by the vmkernel after boot.
B. The adapter must support iBFT or UEFI.
C. The adapter must support FBFT or FBPT.
D. Multi-pathing options must be configured in the Boot ROM.
Correct Answer: AC
Explanation/Reference:
Explanation:
ESXi supports boot from FCoE (Fibre Channel over Ethernet) capable network adapters.
When you install and boot ESXi from an FCoE LUN, the host can use a VMware software FCoE adapter and a network adapter with FCoE capabilities.
The host does not require a dedicated FCoE HBA.
You perform most configurations through the option ROM of your network adapter. The network adapters must support one of the following formats, which communicate parameters about an FCoE boot device to VMkernel.
FCoE Boot Firmware Table (FBFT). FBFT is Intel propriety.
FCoE Boot Parameter Table (FBPT). FBPT is defined by VMware for third-party vendors to implement software FCoE boot.
The configuration parameters are set in the option ROM of your adapter. During an ESXi installation or a subsequent boot, these parameters are exported in to system memory in either FBFT format or FBPT format. The VMkernel can read the configuration settings and use them to access the boot LUN.
Multipathing is not supported pre-boot. Therefore, multipathing options must be configured by the VMkernel after boot.
Incorrect Answers:
B: The adapter must support FBFT or FBPT not iBFT or UEFI. Therefore, this answer is incorrect.
D: Multipathing is not supported pre-boot. Therefore, you should not configure multipathing options in the Boot ROM so this answer is incorrect.
