Question: What is the primary expected outcome for a network operator when achieving full autonomy in fault management, as per the autonomous network levels concept?
Option 1: Increased Capital Expenditure (CAPEX) for new infrastructure
Option 2: Reduced Operational Expenditure (OPEX) through minimized manual intervention
Option 3: Enhanced security risks due to reduced human oversight
Option 4: Immediate elimination of all network and service failures
Explanation: Achieving full autonomy in fault management is expected to reduce the need for manual involvement in tasks related to identifying and resolving network faults. This reduction in manual labor directly contributes to lowering Operational Expenditure (OPEX) for the network operator, as fewer resources are required for fault supervision and recovery processes.
