Which option correctly defines the grid power redundancy mode on Cisco Nexus 7010, Nexus 7009, and Nexus 7018 chassis?
A.
This mode guards against the failure of either one power supply or one grid, and the available power is always the minimum of input source and power supply redundancy.
B.
This mode guards against the failure of one input circuit. The power available to the system is the minimum power provided by either of the input sources.
C.
This mode provides no redundancy. The power available to the system is the sum of the power outputs of all power supplies.
D.
This mode guards against the failure of one of the power supplies. The power available to the system is the sum of the two least-rated power supplies.
