質問 # 55
Accessibility KPIs such as RRC Connection Setup Success Rate drop sharply for a single cell, while neighboring cells remain normal. What should the NOC engineer check FIRST?
正解：C
解説：
When accessibility KPIs such as RRC Connection Setup Success Rate drop sharply for one specific cell while neighboring cells remain normal, the most productive investigation focuses on factors specific to that cell:
reviewing recent alarms (hardware, transport, or synchronization faults affecting only that cell) and checking the configuration management audit trail for any recent parameter change, neighbor relation update, or feature activation that coincided with the KPI drop. Because the issue is localized to a single cell rather than affecting the surrounding area broadly, it is unlikely to be caused by something network-wide such as handset operating system versions used nationwide, and it is entirely unrelated to the billing system or NetAct dashboard appearance settings. Correlating the timing of the KPI degradation with that cell's alarm history and recent CM changes is a standard, effective root-cause approach for localized accessibility issues.

During remote piloting of a RET replacement, the field engineer reports that the new RET unit is physically connected, but the NOC engineer cannot detect it during an AISG device scan, while other ALDs on the same antenna line are detected normally. What is a likely cause the NOC engineer should consider?
正解：C
解説：
When other Antenna Line Devices on the same AISG bus are detected normally but a newly connected device is not, two likely causes should be considered. First, AISG devices are addressed individually on the shared bus, and if the new RET unit has a factory-default or previously configured address that conflicts with an address already in use by another device on the same line, it may fail to respond correctly during discovery due to this addressing conflict. Second, despite being reported as 'physically connected,' there may be a faulty or incomplete connection specific to that device's bus connection point - such as a loose connector at the device itself - that does not affect the other devices already established on the line. The NOC engineer should work with the field engineer to check for addressing conflicts (potentially requiring the new device's address to be changed) and to verify its specific bus connection. RET tilt range, NR-ARFCN, and Tracking Area Code have no relevance to AISG device discovery issues.
質問 # 57
An AirScale base station simultaneously raises a 'Cell Out of Service' alarm and an 'RF unit communication failure' alarm. How should a NOC engineer typically interpret this combination using alarm correlation principles?
正解：B
解説：
Alarm correlation in Fault Management helps distinguish a root-cause alarm from symptom (consequent) alarms that appear together for a single underlying problem. In this scenario, an RF unit communication failure indicates a problem with the radio hardware or its link to the baseband, which directly prevents the cell served by that RF unit from operating - this generates the Cell Out of Service alarm as a direct consequence. NOC procedure is to focus remediation on the root-cause alarm (the RF unit communication failure); resolving it should automatically clear the dependent Cell Out of Service alarm. Treating both as separate, unrelated faults wastes troubleshooting effort on what is really a single underlying issue. NetAct can display many simultaneous alarms per element, and a Cell Out of Service alarm is itself a symptom, not a cause of hardware failure.
質問 # 58
A NOC engineer is trying to isolate whether a fault originates in the baseband processing unit or in an RF module of an AirScale BTS. What is a useful FIRST diagnostic step?
正解：C
解説：
When isolating a fault between baseband processing units and RF modules, checking the status and alarm details of the interconnecting interface - typically a CPRI or eCPRI link in AirScale architectures - between the System Module and the Radio unit is a logical first step. Alarms or abnormal status on this link can quickly reveal whether the problem lies in the connection itself (such as a fiber/cable fault or configuration mismatch) or within one of the connected components. This follows the principle of checking interfaces and boundaries before assuming a specific component has failed, avoiding unnecessary or premature hardware replacement. Replacing the antenna skips this diagnostic step entirely and risks an unwarranted field action.
Restarting NetAct is a network-wide action inappropriate for a single-site fault. Increasing transmit power to
'test' a suspected hardware issue is not a valid diagnostic method and could create interference.
質問 # 59
How do NetAct and the AirScale BTS local Element Manager (Site Manager) typically relate to each other in day-to-day remote operations?
正解：A
解説：
NetAct provides a consolidated, network-wide view of alarms, performance, configuration, and software status for all managed base stations, enabling efficient centralized operations at scale - this is the day-to-day tool for NOC monitoring and bulk provisioning. The BTS Site Manager (Element Manager) complements NetAct by providing detailed, element-specific access for situations requiring deep local diagnostics, such as reviewing local hardware status, logs, or actions not yet reflected centrally, or when central connectivity to a site is degraded. These two tools work together rather than as substitutes for one another. NetAct supports Nokia's Single RAN concept across 2G, 3G, 4G, and 5G technologies on shared hardware, so describing it as
2G/3G-only is incorrect, and the Element Manager is scoped to a single element rather than managing multiple sites network-wide, which is NetAct's role.
