Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 2

A network engineer is investigating the cause of a service disruption on a network segment and executes the debug condition interface fastethernet f0/0 command. In which situation is the debugging output generated?

Answer options

• A. when packets on the interface are received and the interface is operational
• B. when packets on the interface are received and logging buffered is enabled
• C. when packets on the interface are received and forwarded to a configured syslog server
• D. when packets on the interface are received and the interface is shut down

Correct answer: A

Explanation

The correct answer is A because debugging output is generated only when the interface is operational and receiving packets. The other options are incorrect as they mention conditions that do not trigger debugging output, such as the interface being shut down or the presence of logging buffered or syslog configurations.
