（D）SON Network Optimizer

（A）It connects the RF unit to the baseband unit within a single base station

（B）It is used exclusively for software downloads from NetAct to the base station

（C）It connects the gNB to the core network for user authentication only

（D）It provides direct communication between gNBs to support functions such as handover signaling and data forwarding during mobility

（A）The configuration of neighboring cells

（B）The site's AC-to-DC power supply system feeding the equipment

（C）NetAct user account permissions

（D）A software licensing issue on the base station

（A）The NOC engineer travels to the site to physically perform the hardware replacement alongside the field engineer

（B）The NOC engineer remotely controls the field engineer's vehicle to ensure timely arrival at the site

（C）The NOC engineer uses centralized OandM tools to guide the field engineer through the procedure step- by-step, performing remote configuration, verification, and diagnostic actions while the field engineer carries out the physical tasks on site

（D）The NOC engineer has no active role and simply waits for the field engineer to report task completion

（A）Immediately replace the antenna

（B）Increase transmit power to see if the fault changes

（C）Check the status and alarm details of the interface (such as CPRI/eCPRI links) between the System Module and the RF unit

（D）Restart the entire NetAct management server

（A）Assuming every fault automatically requires a full site rebuild

（B）Disregarding any alarm correlation information available

（C）Replacing hardware components at random until the alarm clears

（D）Using available remote diagnostics - alarms, correlation, PM data, interface status, and logs - to determine whether the fault likely lies in the baseband, RF, transport, or external/environmental domain
