For proper time synchronization, which protocol must be configured and reachable by all collaboration nodes?

Explanation:
Time synchronization across collaboration nodes must have a common time source. The protocol used to distribute time over a network is NTP. By configuring all collaboration nodes as NTP clients (or pointing them to reachable NTP servers), clocks stay aligned, which is essential for accurate logging, certificate validity checks, event sequencing, and scheduling. The other protocols—LDAPS, SMTP, and FTP—are for directory access, mail, and file transfer, not for distributing time, so they don’t provide the necessary clock synchronization. Ensure network connectivity to the NTP servers and allow UDP port 123 through firewalls.
