CompTIA Network+ N10-009 Practice Question
A network administrator suspects that a network issue is related to an incorrect configuration on a newly deployed router. After interviewing users and identifying the symptoms, the administrator has established a theory. What is the BEST next step to confirm if their theory about the router's configuration is the cause of the issue?
Analyze the router's log files for error messages.
Reboot the router to see if the problem persists.
Replace the router with a different model to determine if the issue resolves.
Implement the suspected configuration changes on a test router or in a controlled segment of the network.
