Which two are true with respect to the unified ports on the Cisco Unified Computing System 62XX Fabric Interconnect? (Choose two.)
A. The port mode is automatically discovered after plugging in a LAN or Fibre Channel-attached cable.
B. By default, unified ports that are changed to Ethernet port mode are set to uplink Ethernet port type.
C. Ethernet ports must be grouped together in a block and must start with the first port and end with an odd numbered port.
D. Alternating Ethernet and Fibre Channel ports is supported on the expansion module.
E. After making port mode changes on an expansion module, the module will reboot.
F. In a standalone configuration, making port mode changes to the fixed module will not cause the fabric interconnect to reboot.
C is worng.
Ethernet ports must be grouped together in a block. For each module (fixed or expansion), the Ethernet port block must start with the first port and end with an even numbered port.
The answer is B and E
The unified ports are grouped as two interfaces at a time. It is true that it must be started with the first port which is 1/1 but in this case, the group also includes the port 1/2 as well. When you add 1/3, port 1/4 is being added automatically and this can not be changed. The grouping ends with even numbers (ends with 1/2, 1/4.. 1/48)
