Power Save Configuration Parameters

CF.

The Power Save feature for Cisco 9971 IP Phones helps conserve energy by turning off the display and other phone features when they are not in use. This feature can be configured using several parameters, two of which are:

A. Phone On Time: This parameter specifies the amount of time the phone should remain active before it goes into Power Save mode. When the phone is idle for this amount of time, it will turn off the display and other non-essential features to conserve power.

B. Phone Off Idle Timeout: This parameter specifies the amount of time the phone should remain in Power Save mode before it shuts down completely. If the phone remains idle for this amount of time, it will power off to conserve energy.

C. Day Display Not Active: This parameter specifies the days of the week when the phone should not display any information on the screen. This feature can be used to save power during weekends or other times when the phone is not in use.

D. Enable Audio Alert: This parameter allows the phone to play an audio alert when it enters or exits Power Save mode. This feature can be useful for alerting users when the phone is about to shut down or when it becomes active again.

E. Enable Power Save Plus: This parameter enables an enhanced Power Save mode that conserves even more energy by turning off additional phone features such as the Ethernet port and speakerphone.

F. Display on Duration: This parameter specifies the length of time that the phone's display should remain active before it turns off to conserve power.

In summary, the correct answers are A. Phone On Time and B. Phone Off Idle Timeout, as these are the two parameters that directly control the Power Save feature of the Cisco 9971 IP Phone.
