質問 # 92
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 # 93
After a remote configuration change causes unexpected cell behavior, and the automatic fallback mechanism does not fully resolve the issue, what is the most appropriate next step for the NOC engineer?
正解：D
解説：
When a configuration change leads to unexpected behavior and any automatic fallback does not fully restore normal operation, the appropriate recovery action is to restore the affected network element's configuration from the most recent verified backup taken before the change was applied. This returns the element to its known-working state, addressing the immediate service impact while the root cause of the unexpected behavior from the new configuration can be investigated separately, outside of the live production environment if needed. This is precisely why taking and verifying a pre-change backup is emphasized as a best practice - it provides exactly this kind of recovery option. Decommissioning the cell is a drastic and disproportionate response to a configuration issue; applying an unrelated template introduces further uncertainty and risk; and taking no action prolongs any service degradation unnecessarily, which is inconsistent with the NOC's responsibility to restore service promptly.
質問 # 94
What is the role of the Managed Object Model (MOM) in Nokia's RAN configuration management framework?
正解：D
解説：
The Managed Object Model (MOM) defines the structured, hierarchical representation of all configurable entities within the network - such as network elements, their subordinate functional units, cells, and the individual parameters associated with each object - along with the relationships between them. Configuration management tools, including NetAct CM applications, rely on the MOM to know what objects exist, what parameters each object type supports, valid value ranges, and how objects relate to one another (for example, a cell object existing as a child of a baseband equipment object). Understanding the MOM is important for NOC engineers performing configuration changes, since it determines where a given parameter resides within the object hierarchy and what other objects or parameters might be affected by a change. The MOM is a configuration management construct and is unrelated to physical cabling documentation, alarm history (a fault management function), or software upgrade packages (a software lifecycle management function).
質問 # 95
An AirScale base station simultaneously raises a 'Cell Out of Service' alarm and an 'RF unit communication failure' alarm. How should a NOC engineer typically interpret this combination using alarm correlation principles?
正解：B
解説：
Alarm correlation in Fault Management helps distinguish a root-cause alarm from symptom (consequent) alarms that appear together for a single underlying problem. In this scenario, an RF unit communication failure indicates a problem with the radio hardware or its link to the baseband, which directly prevents the cell served by that RF unit from operating - this generates the Cell Out of Service alarm as a direct consequence. NOC procedure is to focus remediation on the root-cause alarm (the RF unit communication failure); resolving it should automatically clear the dependent Cell Out of Service alarm. Treating both as separate, unrelated faults wastes troubleshooting effort on what is really a single underlying issue. NetAct can display many simultaneous alarms per element, and a Cell Out of Service alarm is itself a symptom, not a cause of hardware failure.
質問 # 96
What is the primary function of the AirScale System Module within an AirScale Base Transceiver Station (BTS)?
正解：A
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.
