質問 # 109
A NOC engineer wants to confirm that a newly installed AirScale BTS has completed commissioning and is ready to carry live traffic. Which indicator provides this confirmation?
正解：C
解説：
Commissioning brings a newly installed AirScale BTS under NetAct management, loads the correct software and configuration, and activates its cells. The definitive operational confirmation that commissioning is complete and the site is ready for live service is that the relevant cells show an unlocked (administratively enabled) state combined with an operational 'in service'/available status in NetAct, and there are no outstanding blocking faults or critical alarms preventing service. This combination of administrative and operational state, together with a clean alarm list, is what NOC engineers check before confirming a site is live. Appearing on a mapping tool, having fiber physically installed by the transport provider, or having power equipment installed are all useful prerequisite facts about the site's physical readiness, but none of them confirm that the RAN equipment itself has successfully completed commissioning and is carrying traffic.
質問 # 110
A NOC engineer notices that a cell's PRB (Physical Resource Block) utilization is consistently above 90% during peak hours. What does this MOST LIKELY indicate?
正解：B
解説：
PRB (Physical Resource Block) utilization represents the proportion of a cell's available radio resources that are actively being used to carry traffic at a given time. Consistently high PRB utilization (for example, above
90%) during peak hours indicates the cell is approaching, or already experiencing, capacity congestion - there is little to no spare radio capacity to allocate to new or existing users during busy periods. This can directly affect throughput-related (Integrity) KPIs, since users may receive fewer resources than under lighter load, and can also impact accessibility if the cell becomes unable to admit new connections. This condition does not indicate a hardware failure - the cell is clearly operating and carrying significant traffic - is unrelated to PCI configuration, which is an identification parameter rather than a capacity indicator, and has no relationship to NetAct database storage. High PRB utilization is a capacity signal that may prompt load balancing, optimization, or capacity expansion actions.
質問 # 111
After a field engineer replaces an RF unit, the NOC engineer observes that the eCPRI link between the baseband and the new RF unit remains down, even after the cell is unlocked. What should the NOC engineer do first?
正解：B
解説：
When an eCPRI (or CPRI) link remains down immediately following a physical hardware replacement, the most probable and easily verified cause is a physical-layer issue introduced during the replacement itself - such as a fiber connector not being fully seated, an SFP transceiver not properly inserted, a mismatched or faulty SFP module, or an incorrect port connection. Since the field engineer is already on site with direct physical access, the most efficient first step is to ask them to verify these physical connections before the NOC engineer invests time in deeper remote diagnostics, which would be premature given how common and simple physical connection issues are immediately after hardware work. Ordering a new baseband module is a significant escalation that should only follow ruling out simpler causes; locking the cell and closing the ticket would leave the site non-functional; and PLMN ID has no relationship to eCPRI link establishment, which operates at a lower layer entirely unrelated to network identity broadcasting.
質問 # 112
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 # 113
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.
