During an after-hours investigation you determine that a Windows Server 2022 file server crashes because of an outdated Broadcom 10 GbE NIC driver. You reproduce the failure on a lab system and confirm that installing the latest vendor-signed driver keeps the server stable for 48 hours. According to the CompTIA troubleshooting methodology, which action should you perform next on the production system?
Apply the new NIC driver to the production server immediately and monitor for crashes.
Establish a plan of action that includes notifying stakeholders and scheduling downtime to update the driver.
Roll back the driver on the test server to verify full functionality before production deployment.
Document the troubleshooting steps and results in the ticketing system.
Once a theory has been tested and confirmed, the next step in the CompTIA troubleshooting methodology is to establish a plan of action to resolve the problem and identify potential effects. That plan typically includes tasks such as backing up the system, notifying affected users or stakeholders, scheduling an approved maintenance window, and defining a rollback procedure. Only after a plan is in place should the fix be implemented. Documenting the work and verifying functionality occur in later steps, not immediately after the theory is confirmed.
