Hi there.
Currently ploughing thorough a book on Red Hat Certified System Administrator - Red Hat Enterprise Linux 8 - Training and Exam Preparation Guide (EX200) by Asghar Ghori. I'm on Chapter 18, page 417,418, covering NTP, and I'm stuck on what seems to be conflicting information, but is probably because I'm missing something. (Attached are two pages highlighted)
Put simply my understanding is a Time Reference is Stratum 0, a Primary NTP Server is Stratum 1, and a Secondary NTP Server is Stratum 2. NTP Peers can only exist if they share the same Stratum Levels. However the book also states that Primary and Secondary Servers can be peers of each other - which seems logically impossible given peers are supposed to share the same Stratum Level?
Thanks for any help,
Richard
