* Fiber Connection Loss Overview :
* Fiber connection points introduce optical loss due to imperfections in alignment, reflections, or contamination.
* Loss Comparison :
* Movable Connector : Highest loss due to potential misalignment, contamination, and reflections.
* Cord End Connector : Moderate loss, as these connectors are typically factory-polished and more stable than movable connectors.
* Splicing : Lowest loss, as fusion splicing provides near-perfect alignment and minimal reflection.
* Why C?
* The order of losses from highest to lowest is: Movable connector > Cord end connector > Splicing .
Thus, the correct answer is C .

NMS configuration requires:
* A: Device name for identification.
* B: SNMP community string for authentication.
* C: IP address for communication.
* D (Incorrect): Routing is handled by network devices, not NMS parameters.
