In NTP terminology, what does the 'stratum' of a time source indicate?

The speed at which the time server can respond to requests.

The number of hops from the reference clock, with lower numbers being more accurate.

The security level of the time server's authentication mechanism.

The physical location of the time server in the network.

A FreeBSD server is configured as an NTP client with 'server 0.pool.ntp.org iburst'. The administrator checks the system and sees the clock is accurate, but wants to understand how the server maintains accuracy over time. Which statement best describes the role of 'drift' in this context?

Drift is the amount of time the server has been running since the last synchronization.

Drift is the gradual difference between the system clock and the reference time, which ntpd measures and compensates for by adjusting the clock frequency.

Drift is the distance in network hops to the time server, which determines the stratum of the client.

Drift is the time offset between the client and server, which is corrected by a single ntpdate command.

A FreeBSD server is configured with multiple NTP servers in /etc/ntp.conf. The administrator notices that the server is not synchronizing with any of them. The ntpq -p output shows that all peers have a reach value of 0. What is the most likely cause?

The server's clock is too far out of sync.

The firewall is blocking outbound UDP port 123.

The server is configured with the wrong timezone.

The ntpd daemon is not running.
