                      質問 # 49
                      A KPI tracks the percentage of established connections or sessions that end abnormally ('dropped') rather than through a normal release procedure. Which KPI category does this belong to?

                      正解：D

                      解説：
                      Retainability KPIs measure whether connections or sessions that have been successfully established remain stable and are terminated through normal procedures, rather than ending abnormally (a 'drop'). A high abnormal release/drop rate indicates retainability problems - subscribers may experience calls or data sessions ending unexpectedly mid-use, significantly impacting user experience even when the initial connection (accessibility) succeeded. This differs from Accessibility, which measures the success of the initial connection attempt; Mobility, which specifically measures handover performance; and Availability, which measures whether a cell or site is in service over time. Retainability degradation can result from radio link failures, interference, transport instability, or hardware issues affecting an already-active connection. NOC engineers monitoring retainability KPIs focus on the stability of in-progress sessions, a key contributor to overall subscriber-perceived quality of service.


                      質問 # 50
                      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：D

                      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 # 51
                      A site reports a 'Rectifier Fault' or 'DC Power Fault' alarm together with multiple equipment alarms across different cabinets. What does the rectifier/DC power fault alarm relate to?

                      正解：D

                      解説：
                      A 'Rectifier Fault' or 'DC Power Fault' alarm relates to the site's power infrastructure - specifically the rectifier units that convert incoming AC mains power into the DC voltage used by BTS equipment, often backed by a battery system to ride through short outages. When this alarm appears alongside multiple equipment alarms across different cabinets or modules at the same site, it strongly suggests a shared power supply problem affecting all equipment dependent on that source, rather than independent hardware faults occurring coincidentally across multiple unrelated components. This is unrelated to software licensing, neighbor cell configuration, or NetAct user permissions. Recognizing this pattern helps the NOC engineer correctly identify a power infrastructure issue as the likely root cause, prompting checks on AC mains status, battery backup health, or coordination with site facilities/power maintenance teams, rather than independently chasing each equipment alarm as a separate RAN hardware fault.


                      質問 # 52
                      When configuring NR-NR (5G-to-5G) neighbor relations to support mobility between two 5G cells operating on different frequency bands, which type of neighbor relation must be established?

                      正解：A

                      解説：
                      When two 5G NR cells operate on different frequency bands (or different carrier frequencies within the same band), mobility between them requires an inter-frequency neighbor relation to be configured. This relation must include the necessary frequency information identifying the target carrier, along with measurement configuration parameters that instruct the UE when and how to measure the candidate target frequency - since, unlike intra-frequency measurements, inter-frequency measurements typically require measurement gaps and are not performed continuously by the UE. An intra-frequency neighbor relation would only be appropriate if both cells operated on the same carrier frequency, which is not the case here. Inter-band 5G-to-
                      5G handovers are not automatic without configuration; the network must explicitly define the relation and measurement parameters to enable the UE to detect and report the target cell. EN-DC relations are specifically for LTE-NR dual connectivity scenarios and are unrelated to NR-NR mobility between two 5G cells.


                      質問 # 53
                      Before issuing any remote commands during a piloting session that will affect a specific cell at a multi-sector site, what verification is critical for the NOC engineer to perform to avoid unintended impact?

                      正解：B

                      解説：
                      At multi-sector sites, or in environments where many similarly named cells exist across a large network, there is a meaningful risk that a NOC engineer could inadvertently issue a remote command - such as locking a cell, adjusting a parameter, or initiating a reset - against the wrong sector or even the wrong site if identifiers are not carefully verified. Before taking any action that affects a specific cell during a piloting session, the NOC engineer should explicitly confirm with the field engineer (and against system records) that the site, sector, and cell identifiers being acted upon correspond exactly to the physical location and equipment the field engineer is working on. This verification step is a critical safeguard against unintended service impact to unrelated cells or sites, which could create a second, unrelated outage on top of the planned activity. The remaining options are entirely unrelated to technical verification and have no bearing on safely executing remote piloting commands.
