I was looking through documentation for NTP access groups. I understand the difference of and "ntp access-group peer" and "ntp access-group serve". I guess I'm having a hard time wrapping my head around "serve-only" and "query-only". I'm trying to understand the appropriate times when to use serve-only and query-only. The documentation seems pretty brief, anyone else have an better way of explaining?
