Nokia 5G RAN Network Operations Expert 認定 NRN-522 試験問題 (Q24-Q29):

質問 # 24
Handover Success Rate is a KPI primarily used to assess which aspect of network performance?

正解：D

解説：
Handover Success Rate measures the percentage of handover attempts - where a UE's connection is transferred from one cell to another, typically as the subscriber moves through the coverage area - that complete successfully without dropping the connection. This KPI falls under the Mobility category of performance management, which assesses how effectively the network maintains service continuity as users move, including intra-frequency, inter-frequency, and inter-RAT mobility procedures such as those involved in 4G-to-5G EN-DC configurations. Poor handover success rates can result from issues such as incorrect or missing neighbor relations, insufficient coverage overlap between cells, interference, or misconfigured handover thresholds and parameters. This KPI is unrelated to software version compliance (tracked through software inventory and management), backup file integrity (a software lifecycle concern), or NetAct license utilization (an administrative matter) - it is specifically a mobility indicator used to detect handover-related degradation affecting users in motion.


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：D

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.


質問 # 26
What does an 'Antenna Line Device (ALD) fault' alarm on an AirScale cell typically indicate?

正解：D

解説：
Antenna Line Devices (ALDs) include components such as Remote Electrical Tilt (RET) controllers, which allow remote adjustment of antenna downtilt, and Tower-Mounted Amplifiers (TMAs), which improve uplink sensitivity by amplifying received signals near the antenna. These devices communicate with the BTS over an AISG (Antenna Interface Standards Group) bus. An ALD fault alarm indicates a problem with one of these antenna-line components or their communication link - for example, a RET controller not responding to commands, a configuration mismatch, or a power/connectivity issue on the AISG bus. This is unrelated to the NetAct database, software licensing, or any core network issue. Recognizing this alarm correctly scopes the problem to antenna-line equipment, which may be resolvable remotely (re-querying or reconfiguring the device) or may require a field technician to inspect AISG cabling or replace the faulty ALD if remote actions fail.


質問 # 27
Why do NOC teams typically schedule software activation activities - which require a base station restart - for late-night or off-peak hours rather than during the day?

正解：D

解説：
Activating new software on a base station typically requires the affected unit (or units) to restart, which causes a brief interruption to service for any UEs connected through that cell during the restart. To minimize the impact of this unavoidable interruption, NOC teams schedule such activities during maintenance windows that coincide with periods of lowest network traffic - commonly late at night or in the early morning hours - when the fewest subscribers are likely to be actively using the network. This reduces the number of dropped sessions and the overall visibility of the brief outage to end users. There is no technical restriction preventing restarts during daylight hours, nor does activation duration meaningfully change based on time of day, and NetAct does not impose a blanket restriction on when configuration changes can be submitted - the scheduling decision is an operational best practice driven by minimizing customer impact, not a technical limitation.


質問 # 28
Which Nokia centralized network management system is primarily used by NOC and technical support personnel to monitor, configure, and manage AirScale 5G base stations remotely from an Operations Center?

正解：A

解説：
NetAct is Nokia's centralized Operations Support System (OSS) and is the primary platform used by NOC and technical support teams to manage AirScale 5G base stations from a centralized Operations Center. It integrates Fault Management (FM), Configuration Management (CM), Performance Management (PM), and Software Management (SWM) modules into a single environment, allowing engineers to monitor alarms, push configuration changes, review KPI dashboards, and manage software lifecycle activities across the entire RAN estate without visiting individual sites. While element-level tools such as BTS Site Manager exist for local diagnostics on a single base station, NetAct is the day-to-day platform for remote, network-wide operations. NetGuard focuses on security analytics, CloudBand on NFV infrastructure orchestration, and Nokia Digital Automation Cloud targets private wireless deployments, so none of these serve as the primary RAN operations management system referenced in remote operations procedures.
