Difficulty: EasyNetwork Logging and Auditing

Which default transport protocol and port pair does standard, unencrypted Syslog use to forward log messages to a centralized logging server?

  1. UDP port 514Answer
  2. B
    TCP port 514
  3. C
    UDP port 161
  4. D
    TCP port 6514

Answer

UDP port 514 is the standard protocol and port combination for unencrypted Syslog messaging.
Standard, unencrypted Syslog operates over UDP port 514. It is widely supported across network devices like switches, routers, and firewalls for low-overhead logging.

Step-by-Step Solution

1
Identify the logging protocol specified in the question.
The target protocol is standard unencrypted Syslog.
Different network logging standards use different default transport layers and port numbers.
2
Recall the standard transport layer and assigned port for traditional unencrypted Syslog.
Standard Syslog relies on UDP at port 514 for message transmission.
UDP 514 provides lightweight, low-overhead event logging from network devices to a Syslog collector.
