Answer: C.
Power Caps and Service Profiles
A service profile is the logical encapsulation of the server identity and physical resource requirements, such as the LAN and SAN addresses, number of Ethernet and storage interfaces, firmware versions, boot order, network VLAN, physical port, and QoS policies. By taking this base concept and adding power as another resource associated with the service profile, Cisco abstracts the management of power caps away from the individual server in the same way that physical identity management is abstracted away from the physical server.
Each service profile can be assigned a power cap policy that defines the relative power priority of a physical server that is associated with that power profile, and the power capping group to which the server belongs. When there is adequate power for all servers, the priorities do not come onto play. In the event that the servers in a given power cap group begin to exceed their group allocation, power is allocated according to the priorities defined in the attached power cap group policy, ensuring that critical loads are throttled last. Additionally, there is an option to designate a server as having no power cap, for workloads whose performance cannot be compromised even to the minor extent that power capping entails.
