Which NTP command configures the local devices as an NTP reference clock source?

The correct answer is C. NTP Master.
NTP stands for Network Time Protocol and is used to synchronize the time of devices on a network. NTP uses a hierarchical system of time sources, with each level of the hierarchy being referred to as a stratum. A device that obtains its time directly from an atomic clock is a stratum 0 device, while a device that receives its time from a stratum 1 device is a stratum 2 device, and so on.
To configure a local device as an NTP reference clock source, you need to configure it as an NTP Master. An NTP Master is a device that provides its own time as a reference for other devices on the network. By default, a device that is configured as an NTP client will look to external NTP servers for time synchronization. However, if a device is configured as an NTP Master, other devices on the network can synchronize their time with it.
To configure a device as an NTP Master, you would use the following command:
ntp master <stratum>
<stratum> parameter specifies the stratum level of the NTP Master. A stratum 1 NTP Master obtains its time from a highly accurate time source, such as an atomic clock. A stratum 2 NTP Master obtains its time from a stratum 1 NTP Master, and so on. In general, it is recommended that you do not configure a device as a stratum 1 NTP Master unless you have access to a highly accurate time source.
In summary, to configure a local device as an NTP reference clock source, you would use the NTP Master command with a specified stratum level.
