JNCIA-Junos: Juniper Networks Certified Associate – Junos (2024) — Question 21

You are trying to diagnose packet loss at interface ge-0/0/3.
In this scenario, which command would help you view error statistics in real time?

Answer options

• A. monitor interface ge-0/0/3
• B. show interface ge-0/0/3
• C. show interface terse
• D. monitor interface traffic

Correct answer: A

Explanation

The command 'monitor interface ge-0/0/3' provides real-time statistics and is specifically designed for monitoring interface performance, including error statistics. The other commands, such as 'show interface ge-0/0/3' and 'show interface terse', are used for displaying current interface status but do not offer live monitoring capabilities. 'Monitor interface traffic' is too broad and does not focus specifically on error statistics for the specified interface.
