A technician has just resolved a network issue where several users were unable to access the company's internal CRM platform. The root cause was found to be an incorrect configuration on a new network device that was recently deployed. Following the resolution of the problem, what is the most appropriate way for the technician to proceed in terms of documentation?
Sending an informal email to the IT team describing the problem and how it was resolved, without further recommendations.
Create a detailed report including the problem description, steps taken to resolve the issue, the root cause, and any recommendations for preventing future occurrences.
Verbally communicating the resolution to the immediate supervisor and considering the matter closed without any written record.
Noting down the issue and resolution on a post-it note and sticking it on the side of the monitor for future reference.
