A. The Nexus 5000 family of switches does not support vPC when running in either NPV or FCoE NPV mode.
B. The MDS 9100 family of switches is an excellent design choice as a Unified Fabric edge switch. 
C. The Nexus 7000 Series Switches can support the NPIV mode of operation， but cannot function as a complete Fibre Channel Forwarder.
D. The Nexus 7000 Series Switches cannot support advanced Cisco Fibre Channel features such as IVR.
E. The MDS family of Cisco Unified Fabric switches supports both the Fibre Channel Forwarder and Fibre Channel Bridge functions.

A. It’s hard-set and cannot be disabled
B. It’s configurable， with an upper limit of 16
C. It’s hard-set but cannot disable best-effort and Fibre Channel
D. It’s hard-set but can disable all but one class
E. It’s configurable with an upper limit of eight

B. associate interface E2/11 to secondary VLANs 14 and 50
C. associate interface E2/11 to primary VLAN 50 and secondary VLAN 14
D. associate interface E2/11 to primary VLAN 14 and secondary VLAN 50

A. It is required to establish the point-to-point FCoE links with the first switch in the path.
B. It is required to establish the point-to-point FCoE links with any switch across multiple Ethernet segments.
C. It is not used to build the FCoE links.
D. It is used to ensure lossless transport.

A. FabricSync is used to synchronize MAC addresses to an adjacent fabric interconnect after a server interface failover.
B. Gratuitous ARPs are sent on fabric interconnect uplinks after a server interface failover. 
C. Fabric failover can be used on vNICs and vHBAs.
D. Fabric failover is configured as part of the service profile.
E. Fabric interconnects in end-host mode use fabric failover instead of spanning tree to provide redundancy on uplink ports.

A. The Ethanalyzer captures control-plane traffic， while SPAN captures all traffic.
B. The Ethanalyzer captures all traffic including control-plane traffic， while SPAN captures only the control-plane traffic.
C. The Ethanalyzer captures only data traffic， while SPAN captures all traffic.
D. The Ethanalyzer captures only control traffic， while SPAN captures data traffic.
