Click the Exhibit button. Referring to the exhibit, which action would synchronize a new router's clock with the NTP Server?

Rebooting the router does not configure NTP synchronization; it merely restarts the device.

The command `set system ntp server 172.25.11.254` is the correct configuration command in Junos OS to specify an NTP server. Once configured and committed, the router will attempt to synchronize its system clock with the designated NTP server.

Configuring an NTP trusted key (`set trusted-key`) is for secure NTP authentication, but it does not enable NTP synchronization on its own; the NTP server must first be specified.

The `set date ntp` command is an operational command to manually set the date based on NTP at that moment, not a persistent configuration for ongoing synchronization.
