Difficulty: EasyNetwork Logging and Auditing

A network administrator is configuring centralized event logging on core switches using the standard Syslog protocol. Which port and transport protocol combination does standard Syslog use by default to transmit log messages to a central log server?

  1. UDP port 514Answer
  2. B
    TCP port 514
  3. C
    UDP port 161
  4. D
    UDP port 162

Answer

Standard Syslog defaults to using UDP port 514 for sending log messages to a central server.
Standard Syslog logging services default to using UDP port 514 to transmit system notifications and log messages from network devices to a centralized log host.

Step-by-Step Solution

1
Identify the primary service and protocol being configured.
The target service is centralized event logging via standard Syslog.
The scenario asks specifically for the default transport specifications of Syslog.
2
Recall the standard transport protocol and well-known port number for Syslog.
Standard Syslog messages are sent unencrypted over User Datagram Protocol (UDP) on port 514.
Syslog was designed as a lightweight, connectionless log transport mechanism using UDP port 514.
