A. B. C. D.A.
When configuring the BIOS settings of a UCS C-series rack mount server, an engineer may want to optimize the CPU performance on demand. To achieve this, the engineer needs to adjust the processor power management settings in the BIOS.
There are several CPU power management states available in the BIOS, which can affect the CPU's performance and power consumption. The four options listed in the answers are all related to these power management states:
A. C6 Retention: This state is a deeper sleep state that provides the lowest power consumption and allows the CPU to retain context. The CPU will not respond to interrupts or wake-up events, which may negatively impact performance.
B. C6 non-Retention: This is similar to C6 Retention, but the CPU does not retain context, which means that it will take longer to wake up from this state. This may also negatively impact performance.
C. C2 state: This state is a lower power state than C0 (the active state) but provides faster wake-up times than C6. However, it may still have an impact on performance.
D. C0/C1 state: This is the active state of the CPU, where it is fully powered on and able to respond to requests. This state provides the best performance but also consumes the most power.
To achieve the most optimal on-demand CPU performance, the engineer should select the C0/C1 state (answer D) in the BIOS settings. This will ensure that the CPU is fully powered on and able to respond to requests as quickly as possible, without any delay or impact on performance. However, it should be noted that this may also increase power consumption and generate more heat, which may require additional cooling measures to be put in place.
