Which protocol is the foundation for unified fabric as implemented in Cisco NX-OS?
A . Fibre Channel
B . Data Center Bridging
C . Fibre Channel over Ethernet
D . N proxy virtualization
E . N Port identifier virtualization
Answer: C
Explanation:
Fibre Channel over Ethernet (FCoE) is one of the major components of a Unified Fabric. FCoE is a new technology developed by Cisco that is standardized in the Fibre Channel Backbone 5 (FC-BB- 5) working group of Technical Committee T11 of the International Committee for Information Technology Standards (INCITS). Most large data centers have huge installed bases of Fibre Channel and want a technology that maintains the Fibre Channel model. FCoE assumes a lossless Ethernet, in which frames are never dropped (as in Fibre Channel) and that therefore does not use IP and TCP.
