질문 # 51
What is the primary purpose of performing a configuration audit that compares a live network element's current parameter settings against an approved configuration baseline or template?
정답：C
설명：
A configuration audit compares the actual, currently applied parameter settings on a live network element against a reference baseline or approved configuration template that represents the intended, standardized configuration for that element type or role. The primary purpose of this comparison is to detect configuration drift - differences that may have arisen from unauthorized manual changes, incomplete rollbacks, errors during bulk updates, or undocumented local modifications. Identifying such deviations is important for maintaining configuration integrity across the network, ensuring consistent behavior across similar cells, supporting troubleshooting (since unexpected parameter values are a common root cause of localized issues), and meeting internal governance or regulatory compliance requirements around change control. This process is distinct from performance monitoring (PRB utilization, handover success rate), which relies on PM counters, and from fault management, which tracks active alarms - configuration audits specifically address the state of configuration parameters themselves.
질문 # 52
A cell consistently shows PRB utilization above 90% during peak hours, along with a rising number of RRC Connection Rejections due to insufficient resources. What does this combination of indicators most strongly suggest?
정답：D
설명：
Sustained PRB utilization above roughly 90% indicates that nearly all available radio resources in the cell are being consumed, leaving little headroom for new connections or additional traffic. When this is combined with an increasing rate of RRC Connection Rejections specifically attributed to insufficient resources, it strongly indicates that the cell's admission control function is actively rejecting new connection attempts because demand exceeds available capacity - a clear signature of capacity congestion during busy periods.
This is fundamentally different from a hardware fault (which would typically generate equipment alarms and affect availability rather than just capacity), a synchronization loss (which affects timing-sensitive operations and often triggers specific sync alarms), or a neighbor relation issue (which would primarily affect mobility KPIs). Recognizing this pattern is important because it points toward capacity planning actions - such as carrier expansion, load balancing, or additional sectorization - rather than fault remediation.
질문 # 53
A 'High VSWR' (Voltage Standing Wave Ratio) alarm is raised on an RF unit's antenna branch. What does this alarm typically indicate a problem with?
정답：A
설명：
Voltage Standing Wave Ratio (VSWR) measures how efficiently RF energy transmitted by the radio unit is delivered into the antenna system versus being reflected back due to an impedance mismatch. A High VSWR alarm indicates a significant mismatch on a particular antenna branch or port, commonly caused by issues such as a damaged or loose feeder cable connection, a faulty or improperly seated RF connector, moisture
/water ingress into a connector, or physical damage to an antenna element. This is a radio-frequency hardware issue on the affected branch and is entirely unrelated to NetAct server storage, core network mobility functions, or billing systems. For NOC engineers, a persistent High VSWR alarm typically signals that a field visit may be needed to inspect and repair the physical RF connections or replace damaged hardware on that antenna line, since it is a physical-layer condition not resolvable through remote configuration alone.
질문 # 54
A NOC team is investigating a degradation in E-RAB / QoS flow setup success rate for a specific gNB.
Which approach is MOST effective for identifying the root cause?
정답：C
설명：
Investigating a degradation in E-RAB or 5G QoS flow setup success rate for a specific gNB is most effectively approached by correlating multiple data sources covering the affected time period: checking active alarms on that gNB (hardware, transport, or signaling faults), reviewing the configuration management audit trail for any recent parameter change that coincided with the degradation, and examining relevant performance counters such as resource availability/congestion indicators, transport interface statistics, and signaling success/failure counts. This multi-source correlation identifies whether the degradation stems from a hardware fault, a configuration error, a capacity constraint, or a transport issue, enabling targeted remediation. Reviewing only high-level summary reports lacks the technical granularity required. Restarting NetAct is a drastic, unfocused action unrelated to a single gNB's issue and risks disrupting network-wide monitoring. Assuming the cause is always subscriber devices, without first checking network-side data, skips the most relevant and controllable areas of investigation.
질문 # 55
What best describes the role of 'remote piloting' as performed by a NOC engineer supporting a field engineer during an on-site hardware replacement?
정답：B
설명：
Remote piloting describes a collaborative working model in which a NOC engineer, using centralized O and M tools such as NetAct and element managers, actively supports a field engineer performing physical work at a site. The NOC engineer's responsibilities typically include preparing the network element for the activity (such as locking affected cells), providing real-time guidance based on system status and diagnostic data, performing remote verification steps (such as confirming a replaced module is detected and operating correctly), and executing any remote configuration steps the new hardware requires. This combination of remote expertise and on-site physical capability allows complex maintenance to be carried out efficiently without requiring every engineer involved to have both deep RAN engineering and bring physically present. It is an active, collaborative role - not a passive one - and it relates only to the technical task at hand, not to logistics such as travel arrangements.
