質問 # 97
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 # 98
A NOC engineer observes an 'alarm storm' - dozens of alarms appearing within seconds across multiple cells served by the same site. What is the MOST likely explanation?
正解：D
解説：
An 'alarm storm' - many alarms appearing across multiple cells at a single site within a short window - is a classic indicator that a shared resource serving all of those cells has failed. Multiple cells at a site commonly depend on the same System Module (baseband), the same transport connection back to the aggregation/core network, the same power supply, or the same synchronization source; a failure in any one of these shared elements can simultaneously impact every dependent cell, producing a burst of correlated alarms.
Recognizing this pattern allows the NOC engineer to search for a single common-cause fault - for example, a transport outage or System Module failure - rather than treating each cell's alarms as independent issues requiring separate investigation. It is extremely unlikely that multiple independent hardware faults occur simultaneously by coincidence, and such patterns should never be dismissed as a routine NetAct bug or simply ignored.
質問 # 99
Within NetAct, which functional module is primarily responsible for planning, distributing, and activating software packages across base stations?
正解：A
解説：
The Software Management (SWM) module within NetAct is the centralized functional area responsible for the end-to-end software lifecycle of base stations and other network elements, including planning software deployment campaigns, distributing (downloading) software packages to target network elements, scheduling and triggering activation, and monitoring the success or failure of these operations across potentially large numbers of sites. This is distinct from Fault Management (FM), which handles alarms and fault conditions; Performance Management (PM), which handles KPI and counter-based performance data; and Configuration Management (CM), which handles parameter and configuration provisioning. While these modules may interact - for example, a software activation might generate alarms visible in FM, or a software change might necessitate subsequent configuration adjustments via CM - the core responsibility for managing software packages, versions, and activation campaigns rests specifically with SWM, making it the primary tool a NOC engineer would use for software lifecycle activities.
質問 # 100
What is the key difference between a cell that has been administratively 'locked' (disabled) and a cell that reports 'Out of Service' due to a fault?
正解：A
解説：
'Locked' (administratively disabled) describes a deliberate, controlled state set by an operator or engineer - for example, intentionally taking a cell out of service for planned maintenance, an upgrade, or a configuration change window. This is an expected, reversible action: the cell can be 'unlocked' once the work is complete. 'Out of Service' due to a fault, by contrast, reflects an unintended operational failure - the cell was expected to be operating normally, but a fault condition (such as a hardware, transport, or synchronization issue) has prevented it from doing so, typically accompanied by one or more alarms.
Distinguishing these states matters for NOC engineers: a locked cell appearing down is expected and requires no fault investigation, whereas an unexpectedly out-of-service cell requires diagnosis. Neither state inherently relates to transmit power, and out-of-service conditions are not always due to software upgrades.
