Syslog uses which port on UDP to send messages to a centralized log server?

• A. TCP port 514
• B. UDP port 161
• C. UDP port 514
• D. TCP port 162

Answer: (C)

Syslog messages are sent to a central log server using UDP on the standard syslog port. This choice keeps the transport simple and fast, which fits the needs of logging from many devices without adding the overhead of a reliable connection. Because UDP doesn’t guarantee delivery, some messages can be lost, but for many logging scenarios that trade-off is acceptable. The other options point to different services or transport methods (for example, SNMP uses its own ports, and some syslog setups use TCP instead of UDP on other ports). So the best-fit answer is the UDP use on the standard syslog port.
