A user cannot reach a web server on the company network. You suspect the server's firewall is blocking the request. Which action would BEST test this theory?

Ask the user to try a different browser

Ping the server's IP address from the user's workstation

Check the server's event logs for security-related entries

Temporarily disable the server's firewall and retry the connection

You need to replace a core switch that is failing. The switch provides connectivity for multiple VLANs and also acts as the DHCP relay agent. You have a replacement switch available. What should be included in your plan of action?

A plan to reconfigure all VLANs from scratch on the new switch

A plan to replace the switch without testing the configuration

A configuration backup of the old switch and a rollback plan if the new switch fails

A plan to disable DHCP relay on the new switch to simplify setup

Why is documenting findings, actions, and outcomes an important final step in the troubleshooting methodology?

It is required to test the theory of probable cause

It ensures the solution is implemented correctly

It replaces the need for verification

It provides a reference for future troubleshooting and helps identify recurring issues

A user reports that they cannot access a shared folder on a server. You ask the user to try accessing the folder from another computer, and it works. What does this indicate?

The user's account is locked out

The problem is likely with the user's computer, not the server or network

The server's permissions are incorrectly configured

The network is experiencing a broadcast storm

After implementing a firewall rule change to allow a new application, you verify that the application works. What else should you do to ensure full system functionality?

Immediately document the change in the firewall policy

Inform the users that the application is now working

Close the ticket without further testing

Test other applications and services that might be affected by the new rule
