質問 # 25
After completing a software upgrade and subsequent configuration adjustments at a site, why is it important for the NOC engineer to update the site's maintenance records and change documentation?
正解：C
解説：
Maintaining accurate and current maintenance records and change documentation - detailing what changes were made, when they were performed, by whom, and the reasoning or ticket reference behind them - provides essential context for future operations. If an issue arises at the site days, weeks, or months later, having a clear record of recent changes allows engineers investigating the new issue to quickly identify whether it might be related to a recent software upgrade or configuration adjustment, significantly speeding up root-cause analysis. This documentation also supports configuration audits, compliance requirements, and knowledge transfer between team members or shifts, ensuring continuity even as different engineers interact with the site over time. While documentation does have value for regulatory and audit purposes, dismissing it as having no operational value is incorrect - it directly supports troubleshooting efficiency. Documentation itself does not trigger software downloads or determine technical parameters like PCI, which are governed by separate configuration and software lifecycle processes.

What is the function of cell reselection priority parameters configured for idle-mode UEs across different frequency layers (e.g., 5G vs. 4G, or different 5G bands)?
正解：D
解説：
Cell reselection priority parameters are broadcast to idle-mode UEs and inform them how to prioritize different frequency layers (such as a 5G band versus an LTE band, or multiple 5G bands) when more than one suitable cell is available for camping. By assigning higher reselection priority to certain layers, an operator can influence idle-mode UE distribution - for example, encouraging UEs to camp on a 5G layer where available to ensure faster initial access to 5G services, or directing UEs away from a layer that is being prepared for maintenance. These parameters work alongside reselection thresholds and timers that prevent excessive reselection (ping-ponging) between layers. They do not control network registration eligibility (which depends on subscription and PLMN matching), transmit power limits (a separate RF parameter), or encryption key management (a security function handled through different mechanisms), but they play an important role in idle-mode load distribution and user experience from the moment a device wakes up.
質問 # 27
Over a period of several weeks, a NOC team observes that a particular cell's average PRB utilization during the busy hour has steadily increased from 60% to consistently above 85%, even though no faults or configuration issues have been identified. What is the most appropriate action based on this trend?
正解：D
解説：
A steady upward trend in busy-hour PRB utilization over multiple weeks, in the absence of faults or configuration changes, is a classic indicator of organic traffic growth gradually consuming available capacity. While the cell may still be performing acceptably at 85% utilization, continuing this trend risks crossing into the congestion range (typically above 90%) where accessibility and throughput KPIs begin to degrade. The appropriate response is proactive: flagging the cell for capacity planning review allows engineers to evaluate options such as adding carriers, adjusting load balancing parameters, or planning sectorization before performance actually suffers. Ignoring the trend risks a reactive, customer-impacting outcome once congestion thresholds are crossed. Locking the cell or reducing transmit power would actively degrade service for existing users and is not an appropriate response to a capacity trend - these actions would be counterproductive and harm the very users the network is meant to serve.
質問 # 28
A NOC engineer is considering performing a remote factory reset on a base station as a troubleshooting step for a persistent issue. What is the most significant risk of this action if performed without proper preparation?
正解：A
解説：
A factory reset typically returns a network element to its default, out-of-the-box configuration state, which generally means erasing the unit's current operational configuration - including cell parameters, neighbor relations, and other site-specific provisioning. If performed without first ensuring a verified, complete configuration backup is available, this action can leave the site without the configuration needed to resume normal operation, requiring a time-consuming restoration from backup or, in the worst case, a full re- commissioning process involving significant manual effort. Given this risk, a factory reset is generally considered a last-resort troubleshooting action, used only when less drastic remote troubleshooting steps have been exhausted, and only after confirming that a usable backup exists and that the operational impact (likely requiring an extended outage for the affected cells) is acceptable and properly scheduled. The action does not automatically create its own backup, nor is its impact limited to cosmetic indicators - it directly affects the unit's operational state.
質問 # 29
Why does Nokia recommend configuring automatic session timeout (inactivity logout) for remote management sessions to AirScale base stations?
正解：D
解説：
Automatic session timeout is a fundamental security control for remote management sessions. If an engineer leaves an authenticated session open and unattended - for example, stepping away from a workstation - anyone with physical or logical access to that workstation could potentially view sensitive configuration data or, more seriously, make unauthorized changes to a live base station, which could impact network stability, security, or subscriber service. Automatically terminating idle sessions after a defined inactivity period minimizes this exposure window. This control is unrelated to site power consumption and does not cause the base station itself to restart - only the management session is closed, while the BTS continues normal operation. It also has no effect on a cell's radio coverage area, which is determined entirely by RF design and configuration parameters such as transmit power and antenna settings.
