To enable iSCSI boot in a Cisco UCS B-Series environment, the network adapters must support iBFT (iSCSI Boot Firmware Table).

The iBFT is a data structure in the firmware of an iSCSI boot-capable network adapter. It contains information about the iSCSI boot target, including the IP address of the iSCSI target, the iSCSI target name, the LUN ID of the boot image, and the boot parameters to be used when booting the server.

When the server boots, it sends an iSCSI boot request to the target. The target responds with the necessary information, including the iBFT, which is used by the server to boot from the iSCSI target.

UEFI (Unified Extensible Firmware Interface) is a replacement for the traditional BIOS firmware interface. It provides a more modern and flexible interface for system firmware, but it is not directly related to iSCSI boot.

MPIO (Multipath Input/Output) is a technique for using multiple paths between a server and storage device to improve performance and reliability. It is not required for iSCSI boot, but it may be used to improve performance and reliability of iSCSI storage access.

vNIC (Virtual Network Interface Card) is a virtual network adapter that is created and managed by the UCS Manager. It is used to connect a virtual machine to a network.

CIMC ( Cisco Integrated Management Controller) is the out-of-band management interface for UCS servers. It provides remote management capabilities for the server, including BIOS configuration, firmware updates, and system monitoring.

Therefore, the correct answer is E. iBFT.
