Which ports on the Cisco UCS 6120XP Fabric Interconnects can operate at either 1 Gb/s or 10 Gb/s?

While ports 1-4 are part of the unified ports, this choice is incomplete as ports 5-8 also share this capability on the 6120XP.

This choice is incorrect because the 6120XP Fabric Interconnect does have unified ports capable of operating at both 1 Gb/s and 10 Gb/s.

This choice is incorrect because only ports 1-8 are unified ports; ports 9-16 are typically 10 Gb/s Ethernet, and ports 17-20 are also typically 10 Gb/s Ethernet or expansion module slots.

The Cisco UCS 6120XP Fabric Interconnect features 20 fixed Ethernet ports, where ports 1-8 are unified ports capable of operating at either 1 Gb/s or 10 Gb/s speeds. These unified ports also support FCoE, allowing them to function as either Ethernet or Fibre Channel ports depending on the configuration.

Ports 17-20 are usually 10 Gb/s Ethernet ports and do not typically support 1 Gb/s speed, nor are they the unified ports that can change speeds.
