質問 # 121
What is the primary function of the AirScale System Module within an AirScale Base Transceiver Station (BTS)?
正解：D
解説：
The AirScale System Module is the central baseband processing unit of the AirScale BTS. It hosts digital baseband processing for the deployed radio technologies, handles control-plane functions, and provides the O and M interface that NetAct and remote engineers use for configuration, fault, and performance management.
Under Nokia's Single RAN architecture, the same System Module hardware can support 2G, 3G, 4G, and 5G concurrently, with the active technology mix determined by software and licensing rather than separate dedicated hardware. RF amplification and the physical antenna interface are performed by separate AirScale Radio (RF) modules, not the System Module. The System Module is not a power supply for the cabinet, and while it receives external timing/synchronization references such as GNSS for network synchronization, it does not itself generate GPS satellite signals.
質問 # 122
Before applying a significant parameter change to a live production cell, what best practice should a NOC engineer follow regarding the cell's current configuration?
正解：B
解説：
Taking a configuration backup or snapshot of the current parameter settings before applying a significant change is a fundamental change management best practice. If the new configuration causes unexpected behavior - such as degraded KPIs, connectivity issues, or unintended interactions with other parameters - having a known-good baseline allows the engineer to quickly roll back to the previous configuration, minimizing service impact and downtime while the root cause is investigated. While some configuration management tools may offer change history or versioning features, relying solely on this without an explicit pre-change backup is risky, and the assumption that changes are always automatically and fully reversible is incorrect. Deleting the existing configuration before applying a new one is highly disruptive and would cause an outage. Disabling alarm reporting during a change is dangerous, as it would prevent the NOC from detecting genuine problems introduced by the change itself, undermining the very monitoring needed to assess the change's impact.

What does the term 'Single RAN' refer to in the context of Nokia AirScale base stations?
正解：C
解説：
Single RAN describes Nokia's architecture in which a common AirScale hardware platform - including the System Module and compatible radio units - can run multiple radio access technologies (2G GSM, 3G WCDMA, 4G LTE, and 5G NR) concurrently on the same site, with the technology mix and capacity determined by software configuration and licensing rather than separate dedicated hardware per generation.
This dramatically simplifies site footprint, power usage, and lifecycle management, and allows 5G to be introduced onto existing sites by adding software/capacity rather than deploying entirely new cabinets. It is unrelated to antenna count limits or SIM card types, and AirScale platforms also support multi-operator RAN sharing, so it does not restrict usage to a single operator. For NOC personnel, Single RAN means configuration, fault, and software management for several technologies may be addressed through the same base station and management session.
質問 # 124
In NetAct Performance Management, what is a 'measurement job'?
正解：D
解説：
In NetAct Performance Management, a 'measurement job' is a configured task that specifies which performance counters or KPIs should be collected, from which network elements (such as specific base stations or cells), and at what collection interval - for example, every 15 minutes or hourly. These jobs are the mechanism by which raw counter data is gathered from the RAN and made available for KPI calculation, reporting dashboards, and threshold-based alerting. Without properly configured measurement jobs covering the relevant counters and elements, the performance data needed to assess network health and detect KPI degradation would simply not be collected. This is distinct from a field technician's scheduled maintenance task, a software upgrade package (a Software Management concept), or a user account (an access control concept) - a measurement job specifically governs the automated, ongoing collection of performance statistics within the PM functional area.
質問 # 125
Why is it considered a best practice to verify the integrity of a configuration or software backup file shortly after it is created, rather than assuming the backup process completed successfully?
正解：D
解説：
A backup operation reporting a successful completion status does not always guarantee that the resulting backup file is complete, uncorrupted, and usable for a future restore - issues such as interrupted transfers, storage errors, or partial writes can sometimes occur without being immediately obvious. The critical risk is that such problems are often only discovered at the moment a restore is actually needed - typically during a recovery from a failed upgrade or configuration change - at which point the absence of a usable backup severely limits recovery options and can significantly extend an outage. For this reason, verifying backup integrity (for example, through checksum validation, file size checks, or test restores where feasible) shortly after creation is considered a best practice, ensuring that if a restore is ever needed, the backup can be relied upon. Backup verification has no relationship to KPI performance, alarm display functionality, or causing repeated restarts - its sole purpose is to confirm the backup's usability for recovery.
