質問 # 101
An operator is considering reducing the PM Result Output Period (ROP) for a set of cells from 15 minutes to
1 minute to enable near real-time troubleshooting. What is the most significant operational trade-off of this change?
正解：A
解説：
Reducing the Result Output Period increases the frequency at which performance counters are collected, processed, and stored, which proportionally increases the volume of measurement data generated by each network element. Moving from a 15-minute to a 1-minute ROP, for example, would generate roughly fifteen times more data points over the same time period. This places significantly higher demand on the file transfer, processing, and storage capacity of NetAct and any downstream analytics systems, and can also increase signaling and processing load on the base stations themselves. While finer granularity can be valuable for short-term, targeted troubleshooting of a specific cell during an active investigation, it is not typically sustainable as a network-wide, long-term configuration. KPI formulas remain valid regardless of ROP, alarm notifications are a separate mechanism unaffected by PM ROP settings, and historical trending remains possible - it simply involves more granular data points.
質問 # 102
Cell Availability KPI is typically calculated based on which factor?
正解：C
解説：
Cell Availability is a KPI that reflects the proportion of time during a measurement period that a cell is actually capable of carrying traffic - that is, it is not blocked by an active fault condition or an administrative lock (an intentional disable for maintenance). It is typically expressed as a percentage of total elapsed time, with downtime due to either faults or planned outages subtracted from the period considered. This KPI provides a high-level view of how reliably a cell has been able to serve subscribers over time, and sustained low availability for a particular cell would prompt investigation into recurring faults or excessive planned outages. It is unrelated to the number of active NetAct user sessions, the count of software upgrades performed (although upgrades may contribute to planned downtime), or signal strength reported by an individual UE, which is a radio measurement rather than a network-wide availability statistic.
質問 # 103
Before activating a newly downloaded software package on a base station, why is it important to verify software compatibility with the unit's current hardware and configuration?
正解：D
解説：
Verifying that a software package is compatible with a base station's specific hardware variants, installed modules, and current configuration before activation helps avoid activation failures or operational issues that can arise when a software load does not properly support the hardware it is being applied to, or when configuration elements are incompatible with structural changes introduced in the new software. While an automatic fallback mechanism may eventually recover the unit to its previous working state if activation fails, relying on fallback as the primary safeguard introduces avoidable service disruption and consumes a maintenance window without achieving the intended upgrade. Compatibility considerations are relevant across all supported technologies within Nokia's Single RAN portfolio, not just legacy systems, and compatibility checks are a software lifecycle planning activity - they do not update physical inventory records or remove the need for post-activation health monitoring, which remains essential regardless of how thorough the pre-activation checks were.
質問 # 104
A field engineer needs to work in close proximity to an antenna to replace a Tower Mounted Amplifier (TMA). What is the NOC engineer's most important responsibility before the field engineer begins this work?
正解：D
解説：
When a field engineer needs to work in close physical proximity to an antenna - such as when replacing a Tower Mounted Amplifier - radio frequency (RF) exposure becomes a safety consideration, since active transmission from the antenna could expose the engineer to RF energy levels exceeding safe limits at close range. The NOC engineer's most important responsibility in this scenario is to coordinate placing the affected cell's RF transmission into a safe state - typically by locking the cell - before the field engineer begins work near the antenna, and to confirm this state is in place before giving the go-ahead. This directly supports the field engineer's physical safety. Increasing transmit power would worsen RF exposure risk and is the opposite of the correct action; scheduling for busy hours is irrelevant to the safety requirement and would also affect more subscribers; and disabling alarm notifications would reduce the NOC's situational awareness during the activity without providing any safety benefit.
質問 # 105
A NOC team uses NetAct to download a new software package to a group of base stations during business hours, but schedules the activation of that software for later that night. What is the primary operational benefit of this 'download now, activate later' approach?
正解：D
解説：
Software lifecycle management for base stations typically separates the download (transfer) phase from the activation phase, because each has different operational implications. Downloading a software package involves transferring a potentially large file to the base station's storage, which consumes transport bandwidth and storage I/O but does not itself interrupt the cell's current operation, since the existing software load continues running unaffected. Activation, by contrast, involves switching to the new software load, which typically requires the affected unit to restart and briefly interrupts service. By downloading during business hours - when transport capacity may be more available and the activation step has not yet occurred - and scheduling activation for a low-traffic maintenance window, the NOC minimizes both the duration of any service interruption and its impact on subscribers. This separation does not eliminate the need for backups, nor does activation occur automatically; it is explicitly scheduled or triggered as a distinct step.
