NEW QUESTION # 75
Why does NetAct support configuring automatic notifications, such as email or SMS, for Critical severity alarms to NOC personnel?
Answer: D
Explanation:
NetAct supports configuring automatic notifications, such as email or SMS alerts, to be sent to designated NOC personnel when alarms of a certain severity - commonly Critical - are raised. This ensures severe issues are brought to the attention of responsible engineers promptly, even if no one is actively viewing the live FM dashboard at that exact moment, helping reduce the time between a fault occurring and corrective action beginning. This notification mechanism complements, rather than replaces, the FM dashboard, which remains necessary for detailed investigation, alarm correlation across the network, and ongoing monitoring of all severity levels. It does not automatically fix any underlying fault - it is purely an awareness mechanism - and has no effect on how many alarms the network actually generates, which is determined by real fault conditions and configured alarm definitions/thresholds, not by notification settings.
NEW QUESTION # 76
Which NetAct functional area provides tools that allow an operator to apply the same parameter change consistently to multiple AirScale base stations or cells in a single operation?
Answer: A
Explanation:
NetAct's Configuration Management (CM) area provides bulk/mass update capabilities that let an operator define a parameter change once - such as updating a neighbor relation, adjusting a power parameter, or enabling a feature - and apply it consistently across many base stations or cells in a single, auditable operation. This is fundamental to standard provisioning tasks covered in remote operations, allowing large- scale configuration rollouts without logging into each element individually, while maintaining consistency and an audit trail of who changed what and when. Fault Management focuses on collecting, displaying, and correlating alarms rather than making configuration changes. Performance Management focuses on collecting and reporting KPI/counter data. Software Management can distribute and activate software packages across multiple base stations, but it does not handle parameter and configuration provisioning, which is the specific domain of Configuration Management's bulk operations tools.
NEW QUESTION # 77
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: A
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 # 78
What is the function of cell reselection priority parameters configured for idle-mode UEs across different frequency layers (e.g., 5G vs. 4G, or different 5G bands)?
Answer: D
Explanation:
Cell reselection priority parameters are broadcast to idle-mode UEs and inform them how to prioritize different frequency layers (such as a 5G band versus an LTE band, or multiple 5G bands) when more than one suitable cell is available for camping. By assigning higher reselection priority to certain layers, an operator can influence idle-mode UE distribution - for example, encouraging UEs to camp on a 5G layer where available to ensure faster initial access to 5G services, or directing UEs away from a layer that is being prepared for maintenance. These parameters work alongside reselection thresholds and timers that prevent excessive reselection (ping-ponging) between layers. They do not control network registration eligibility (which depends on subscription and PLMN matching), transmit power limits (a separate RF parameter), or encryption key management (a security function handled through different mechanisms), but they play an important role in idle-mode load distribution and user experience from the moment a device wakes up.
NEW QUESTION # 79
What is the role of the Managed Object Model (MOM) in Nokia's RAN configuration management framework?
Answer: A
Explanation:
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).
