You are troubleshooting an adjacency formation problem in OSPF using traceoptions. Which command is used to view the output of a traceoptons file called trace-ospf?
Click on the arrows to vote for the correct answer
A. B. C. D.A
The trace output (debug information) is directed to the named log file, which is stored in the /var/log directory. You can view the output as a log file using the "show log" command, or in real-time using the "monitor start" command
The correct command to view the output of a traceoptions file called trace-ospf is A. show log trace-ospf.
When troubleshooting an adjacency formation problem in OSPF using traceoptions, the traceoptions configuration must first be enabled in the OSPF configuration hierarchy. This can be done using the set protocols ospf traceoptions statement.
Once traceoptions has been enabled, the traceoptions output can be viewed using the show log command followed by the name of the traceoptions file, which in this case is trace-ospf. Therefore, the correct command to view the output is A. show log trace-ospf.
Option B. file show /log/trace-ospf is incorrect because it is not a valid Junos command. The correct syntax would be file show /var/log/trace-ospf.
Option C. monitor trace-ospf is also incorrect because it is not a valid command to view the output of a traceoptions file. The monitor command is used to view the real-time operational state of a Junos device.
Option D. show system syslog is incorrect because it is used to view system log messages, not traceoptions output. While traceoptions output can be sent to the system log, it would not be the default behavior.
