NEW QUESTION # 106
Following completion of a hardware replacement and remote piloting activity, which combination of checks represents the most complete final verification before the NOC engineer closes out the activity as successful?
Answer: C
Explanation:
A complete final verification after a hardware replacement and remote piloting activity should confirm multiple dimensions of the site's restored operational state. This includes checking that alarms directly related to the replaced component and the maintenance activity itself have cleared as expected (with any remaining alarms understood and unrelated to the activity), confirming the affected cell has been unlocked and successfully returned to an in-service state, verifying that relevant communication links - such as CPRI
/eCPRI links to RF units or the AISG bus connection to antenna line devices - report normal status, and reviewing short-term performance indicators to confirm they are consistent with the site's established baseline, indicating the cell is performing as expected under real traffic. Only this combination provides genuine assurance that the activity was successful end-to-end. Administrative details like tool packing, serial number matching against shipping records (while useful for inventory purposes), and weather conditions do not address whether the network element is actually functioning correctly.
NEW QUESTION # 107
What is the primary function of the AirScale System Module within an AirScale Base Transceiver Station (BTS)?
Answer: A
Explanation:
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.
NEW QUESTION # 108
What is the primary purpose of performing a configuration audit that compares a live network element's current parameter settings against an approved configuration baseline or template?
Answer: C
Explanation:
A configuration audit compares the actual, currently applied parameter settings on a live network element against a reference baseline or approved configuration template that represents the intended, standardized configuration for that element type or role. The primary purpose of this comparison is to detect configuration drift - differences that may have arisen from unauthorized manual changes, incomplete rollbacks, errors during bulk updates, or undocumented local modifications. Identifying such deviations is important for maintaining configuration integrity across the network, ensuring consistent behavior across similar cells, supporting troubleshooting (since unexpected parameter values are a common root cause of localized issues), and meeting internal governance or regulatory compliance requirements around change control. This process is distinct from performance monitoring (PRB utilization, handover success rate), which relies on PM counters, and from fault management, which tracks active alarms - configuration audits specifically address the state of configuration parameters themselves.
NEW QUESTION # 109
A cell repeatedly raises and clears 'Cell Unavailable' alarms. Performance data shows PRB utilization dropping to zero during exactly the same periods. Which area should be investigated FIRST as the likely root cause?
Answer: A
Explanation:
When a cell repeatedly raises and clears 'Cell Unavailable' alarms, and PRB utilization simultaneously drops to zero during exactly those same intervals, this pattern strongly indicates the cell is genuinely going out of service intermittently, rather than a display or reporting artifact. The investigation should focus on causes capable of producing repeated, short-duration outages: transport link instability (brief link flaps causing loss of the cell's connectivity), loss of synchronization reference (particularly significant for TDD 5G, where sync loss can force a cell to stop transmitting to avoid interference), or unexpected hardware resets/restarts of the baseband or radio unit, potentially linked to environmental issues such as overheating or power fluctuations.
NetAct UI theme settings, subscriber handset models, and the billing system are entirely unrelated to RAN service availability and would not explain this correlated alarm and KPI pattern. Correlating alarm timing with PM data and environmental/transport alarms is a key NOC diagnostic technique.
NEW QUESTION # 110
A NOC engineer is investigating subscriber complaints of being unable to access data services even though their devices show a strong 5G signal and successfully camp on the cell. Which KPI should the engineer examine first to determine whether the issue lies in establishing the data bearer itself?
Answer: D
Explanation:
If a device successfully camps on a cell and shows strong signal levels but cannot access data services, the issue most likely lies beyond the initial radio connection - specifically in establishing the data bearer (PDU session in 5G, analogous to E-RAB in 4G) required to carry user-plane traffic to the core network. The PDU Session/E-RAB Setup Success Rate KPI directly measures how often these bearer establishment procedures succeed, and a low value points to problems such as core network signaling failures, transport issues toward the user-plane gateway, configuration mismatches, or resource allocation failures at the RAN. Cell Availability simply confirms the cell is operational, Handover Success Rate is only relevant once a session is active and mobility occurs, and strong RSRP only confirms good radio coverage - none of these directly explain a failure to establish the data session itself, making the PDU Session/E-RAB Setup Success Rate the correct first KPI to examine.
