Which value indicate the distance from the ntp authoritative time source?

Priority is a metric used in various network protocols to determine preference or precedence, but it does not specifically indicate the distance from an NTP authoritative time source.

Location refers to the physical or logical placement of a device and is not a standard NTP metric for indicating distance from a time source.

Layer, in networking, typically refers to the OSI or TCP/IP model layers and is unrelated to the synchronization distance in NTP.

Stratum in NTP (Network Time Protocol) represents the number of hops away from a primary reference clock, indicating the synchronization distance from an authoritative time source; stratum 1 is directly connected to a primary reference, stratum 2 synchronizes to stratum 1, and so on.
