NEW QUESTION # 33
A NOC engineer increases the configuredMaxTxPower parameter for a 5G cell as part of a coverage improvement initiative. What is the most likely operational consequence of this change?
Answer: D
Explanation:
The configuredMaxTxPower parameter sets the maximum transmit power level the cell is permitted to use for its downlink transmissions, including reference signals and traffic channels. Increasing this value generally allows the cell's signal to reach further and penetrate obstacles more effectively, potentially expanding the effective coverage area and improving signal quality for UEs at the cell edge. However, because radio signals do not respect cell boundaries, a higher transmit power also means the cell's signal will be stronger when received by UEs and sensors in neighboring cell areas, which can increase co-channel or adjacent-channel interference - particularly relevant in dense deployments where cells are closely spaced. This trade-off means power changes should be planned carefully and their impact monitored through KPIs such as SINR and throughput in both the target cell and its neighbors. The parameter has no direct effect on software version, bandwidth configuration, or neighbor relation status, which are governed independently.
NEW QUESTION # 34
Why is it important for NOC personnel to establish a KPI baseline for each cell or site before evaluating whether current performance indicates a problem?
Answer: D
Explanation:
Establishing a KPI baseline for each cell or site - representing typical performance under normal operating conditions, accounting for factors such as time-of-day traffic patterns, geography, and cell configuration - provides the reference point against which current performance can be meaningfully compared. Without a baseline, it is difficult to tell whether an observed KPI value represents a genuine degradation requiring investigation, or simply normal variation for that particular cell. For example, a busy urban cell may normally operate with higher PRB utilization than a rural cell, so what is alarming for one cell may be entirely typical for another. Baselines support effective threshold setting for alerts, help prioritize investigation effort toward genuine anomalies, and are referenced continuously - not only during initial commissioning - whenever assessing whether performance has changed meaningfully. Baselines have no relationship to a cell's maximum transmit power, which is a separate RF configuration parameter.
NEW QUESTION # 35
The PLMN ID broadcast by a 5G cell is composed of which two elements, and what is its primary function?
Answer: B
Explanation:
The Public Land Mobile Network Identity (PLMN ID) is composed of a Mobile Country Code (MCC), which identifies the country in which the network operates, and a Mobile Network Code (MNC), which identifies the specific mobile network operator within that country. This combination is broadcast by every cell as part of its system information and is used by UEs during network selection and registration to confirm they are camping on a cell belonging to their home operator or an authorized roaming partner. Correct PLMN configuration is fundamental: an incorrect PLMN ID would cause UEs belonging to that operator to treat the cell as unsuitable, preventing any subscribers from camping on it. This is entirely separate from Cell ID/TAC (used for tracking and identification within a network), PCI (used for physical-layer cell identification), and transport-layer addressing such as IP/VLAN configuration, which serve different operational purposes.
NEW QUESTION # 36
A NOC team needs to apply an identical parameter change - updating a neighbor relation threshold - across
200 cells in a region. What NetAct CM capability is best suited to perform this efficiently and consistently?
Answer: D
Explanation:
NetAct's Bulk Configuration Management capability, often referred to as Mass Update, is specifically designed for scenarios where the same configuration change needs to be applied consistently across a large number of network elements or cells. Rather than requiring an engineer to manually access each cell individually - which would be slow, error-prone, and difficult to audit - Bulk CM allows the target parameter, new value, and the set of affected cells to be defined once, with the change then propagated and applied consistently across all selected targets, typically with built-in logging and the ability to verify success or failure per element. This significantly reduces the time required for large-scale changes and ensures consistency, which is particularly important for parameters like neighbor relation thresholds where inconsistent configuration across a cluster could create uneven mobility behavior. Software Management's delivery function addresses SW lifecycle, not parameter changes, and Fault Management is unrelated to configuration provisioning.
NEW QUESTION # 37
A NOC team is investigating a degradation in E-RAB / QoS flow setup success rate for a specific gNB.
Which approach is MOST effective for identifying the root cause?
Answer: A
Explanation:
Investigating a degradation in E-RAB or 5G QoS flow setup success rate for a specific gNB is most effectively approached by correlating multiple data sources covering the affected time period: checking active alarms on that gNB (hardware, transport, or signaling faults), reviewing the configuration management audit trail for any recent parameter change that coincided with the degradation, and examining relevant performance counters such as resource availability/congestion indicators, transport interface statistics, and signaling success/failure counts. This multi-source correlation identifies whether the degradation stems from a hardware fault, a configuration error, a capacity constraint, or a transport issue, enabling targeted remediation. Reviewing only high-level summary reports lacks the technical granularity required. Restarting NetAct is a drastic, unfocused action unrelated to a single gNB's issue and risks disrupting network-wide monitoring. Assuming the cause is always subscriber devices, without first checking network-side data, skips the most relevant and controllable areas of investigation.
