350-401 Question #919: Real Exam Question with Answer & Explanation

Question

An engineer is connected to a Cisco router through a Telnet session. Which command must be issued to view the logging messages from the current session as soon as they are generated by the router?

Options

• Alogging host
• Bterminal monitor
• Cservice timestamps log uptime
• Dlogging buffer

Explanation

To display real-time logging messages from a Cisco router to a non-console terminal session (like Telnet or SSH), the terminal monitor command must be issued.

Common mistakes.

• A. The logging host command configures the router to send logging messages to an external syslog server, not to the current terminal session.
• C. The service timestamps log uptime command adds a timestamp to logging messages, but it does not enable their display on the current terminal session.
• D. The logging buffer command configures the size of the buffer where logging messages are stored; messages are viewed from this buffer using the show logging command, not in real-time as they are generated.
