Final answer:
The technician should make the change, document the requester, and document all network changes in this urgent situation.
Step-by-step explanation:
The technician should make the change, document the requester, and document all network changes in this urgent situation. When a request for a network segment is approved through the emergency change management process, it signifies the importance of the change. By documenting the requester and network changes, the technician can maintain proper records and ensure accountability.
It is not recommended for the technician to wait until the maintenance window to make the requested change because a software release could be impacted if the additional network segment is not added immediately. Similarly, sending out a notification to the company about the change or first documenting the potential impacts and procedures may cause a delay and jeopardize the software release.
