The correct answer is B. FCoE. The engineer needs a solution that consolidates Fibre Channel storage access and Ethernet networking over 10 Gigabit Ethernet, supports network booting, integrates with existing Fibre Channel arrays, and ensures lossless data transfer.
Question
An engineer must design a Cisco UCS environment that will connection to a storage area network. The solution must include support for these conditions:
- connectivity to the existing 10 Gigabit Ethernet network
- booting the server infrastructure from the network
- integration with the existing Fibre Channel storage arrays
- lossless data transfer
Which solution should be used to meet these requirements?
Options
- AFCP
- BFCoE
- CCIFS
- DNFS

Why each option
The engineer needs a solution that consolidates Fibre Channel storage access and Ethernet networking over 10 Gigabit Ethernet, supports network booting, integrates with existing Fibre Channel arrays, and ensures lossless data transfer.
FCP (Fibre Channel Protocol) requires dedicated Fibre Channel infrastructure and does not integrate directly with Ethernet to meet all specified requirements.
Fibre Channel over Ethernet (FCoE) encapsulates Fibre Channel frames within Ethernet, allowing storage traffic to run over existing 10 Gigabit Ethernet infrastructure. This technology enables network booting, integrates with existing Fibre Channel arrays, and provides lossless data transfer through mechanisms like Priority-based Flow Control (PFC).
CIFS (Common Internet File System) is a network file sharing protocol that operates over IP and is not designed for block-level storage access or network booting.
NFS (Network File System) is a network file sharing protocol that operates over IP and is not designed for block-level storage access or network booting.
