Host must have reliable time synchronization sources

보통레벨 1자동vmware

설명

Ensuring reliable time synchronization is crucial as various functions like cryptography, audit logging, cluster operations, and incident response/forensics are heavily dependent on synchronized time. Utilizing at least four NTP sources is recommended for achieving reliable time synchronization. The audit runs esxcli system ntp get and requires NTP to be enabled with at least one server. Runs in the ESXi Shell (busybox sh) as root.
