The correct answer is A. ports 45-48 as Fibre Channel uplink ports B. ports 16-19 as uplink ports. Cisco UCS Fabric Interconnect ports connected to an MDS Fibre Channel switch should be configured as Fibre Channel uplink ports, and those connected to a Nexus 5596 Ethernet switch should be configured as standard uplink ports.
Question
Refer to the exhibit. A customer has connected ports from a Cisco UCS 6296 using factory default settings, in this way:
- Ports 45-48 connected to an upstream Cisco MDS switch
- Ports 16-19 connected to an upstream Cisco Nexus 5596 switch
Which two port modes should be used in Cisco UCS Manager? (Choose two.)

- Cports 45-48 as Fibre Channel storage ports
- Dports 16-19 as server ports
- Eports 45-48 as FCoE ports

Why each option
Cisco UCS Fabric Interconnect ports connected to an MDS Fibre Channel switch should be configured as Fibre Channel uplink ports, and those connected to a Nexus 5596 Ethernet switch should be configured as standard uplink ports.
Ports 45-48 are connected to a Cisco MDS switch, which is a dedicated Fibre Channel switch, requiring these Fabric Interconnect ports to be configured as Fibre Channel uplink ports to establish connectivity to the storage fabric.
Ports 16-19 are connected to a Cisco Nexus 5596 switch, which provides Ethernet connectivity, meaning these Fabric Interconnect ports should be configured as standard uplink ports to provide network connectivity to the upstream Ethernet infrastructure.
Fibre Channel storage ports are used for direct connections to Fibre Channel storage arrays, not to an upstream Fibre Channel switch like the MDS.
Server ports on a Cisco UCS Fabric Interconnect are used to connect downstream to UCS blade or rack servers, not upstream to a Nexus switch.
Cisco MDS switches operate using native Fibre Channel protocol, not FCoE, so configuring ports as FCoE ports for an MDS connection would be incorrect.
