質問 # 60
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.

Some alarms in NetAct FM clear automatically once the underlying fault condition no longer exists, while others require manual clearing by an engineer. What characterizes an alarm that requires manual clearing?
正解：D
解説：
Many alarms in NetAct FM are designed to self-clear: once the network element detects that the underlying condition no longer exists - for example, a transient link flap recovering on its own - the element sends a clear notification and the alarm is automatically removed from the active list. However, some alarms represent conditions where the element cannot reliably self-verify resolution, such as certain hardware faults requiring physical intervention, or conditions tied to actions needing human confirmation. These alarms may remain active even after corrective action has been taken, until an engineer manually clears them or the system completes a subsequent successful self-test. NOC engineers need to understand this distinction so the active alarm list accurately reflects current network status, and so that manual clearing is correctly performed as part of completing a maintenance action where required.
質問 # 62
In NetAct Performance Management, what is the standard default Result Output Period (ROP) used for collecting and reporting most cell-level performance measurement counters?
正解：D
解説：
The default Result Output Period (ROP) for performance management counters in Nokia's RAN solution is 15 minutes. This interval provides a practical balance between granularity and system load: it is short enough to allow NOC engineers to detect emerging issues, congestion trends, and KPI fluctuations close to real time, while not generating an unmanageable volume of measurement data that would overwhelm storage and processing resources in NetAct. Fifteen-minute granularity is widely used as the basis for accessibility, retainability, mobility, integrity, and availability KPI formulas, and is the standard interval referenced in performance dashboards and automated reports. While other reporting intervals (such as 1 hour or 24 hours) can be configured for specific measurement jobs or long-term trend analysis, the 15-minute ROP remains the operational baseline for day-to-day RAN performance monitoring and troubleshooting activities performed by remote operations teams.
質問 # 63
During a complex remote piloting activity involving multiple steps and risk of service impact, what additional coordination practice helps ensure accountability and a clear record of what was agreed and performed at each stage?
正解：A
解説：
For complex, multi-step remote piloting activities with potential service impact, using a shared communication channel - such as a bridge call or a logged chat/messaging channel - where each step, its confirmation, and its result are recorded in real time provides significant benefits. It creates a contemporaneous record of exactly what was instructed, performed, and confirmed at each stage, which supports accountability (clarifying who performed or authorized each action) and provides an accurate timeline that can be referenced if an issue arises during or after the activity, or if the activity needs to be reviewed afterward for process improvement. This is in addition to, not a replacement for, the final documentation in the maintenance ticket. Avoiding real-time communication would undermine the collaborative coordination that complex activities require; anonymous channels would defeat the accountability purpose; and performing steps simultaneously without sequencing would be unsafe and likely to cause errors, particularly where later steps depend on the successful completion of earlier ones.
質問 # 64
During a Site Acceptance Test (SAT) for a newly commissioned 5G site, what is the NOC team's typical role?
正解：C
解説：
During a Site Acceptance Test for a newly commissioned site, the NOC team's role centers on remote verification from the centralized operations perspective, complementing the field team's physical inspection and commissioning activities. This typically includes confirming that the new site and its cells are visible, reachable, and manageable through centralized tools such as NetAct (confirming O and M connectivity is correctly established), verifying that all expected cells come into service without configuration errors, checking that no unexpected or unresolved alarms are present that would indicate an incomplete or faulty installation, and reviewing initial performance indicators (such as successful connection attempts and basic KPI reporting) to confirm the site is functioning as intended before it is accepted into normal operation.
Physical inspections of mounting hardware, cabling installation, and commercial/contractual matters fall outside the NOC's remote operational role and are handled by field engineering, construction, and commercial teams respectively.
