NEW QUESTION # 41
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: C
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 # 42
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 # 43
Which NetAct Fault Management view should a NOC engineer use to see alarms that are currently outstanding and affecting the network, as opposed to alarms that have already been resolved?
Answer: A
Explanation:
The Active Alarms list in NetAct Fault Management displays alarms that are currently outstanding (uncleared) and affecting the network in real time, making it the primary view NOC engineers monitor to identify ongoing issues requiring attention and to prioritize response based on severity. The Alarm History
/Log, in contrast, contains records of past alarms - including those already cleared - which is useful for trend analysis, post-incident reviews, and identifying recurring or intermittent faults over time, but is not the appropriate view for real-time triage of current network health. PM Reports relate to performance counters and KPI trends, not fault/alarm conditions, and the Software Inventory view shows deployed software versions across elements rather than fault information. For day-to-day monitoring and prioritizing immediate response efforts, the Active Alarms list is the correct view.
NEW QUESTION # 44
What does the NR-ARFCN (NR Absolute Radio Frequency Channel Number) represent in a 5G cell's configuration?
Answer: D
Explanation:
The NR Absolute Radio Frequency Channel Number (NR-ARFCN) is a standardized numbering scheme defined for 5G NR that maps specific numeric values to corresponding carrier frequencies across the supported frequency range. When configuring a cell, the NR-ARFCN value (rather than specifying the frequency directly in MHz) is used to unambiguously identify the exact carrier frequency the cell will operate on, ensuring consistency across equipment from different vendors and alignment with regulatory frequency allocations. Correct NR-ARFCN configuration is essential for frequency planning, neighbor relation setup (since inter-frequency relations reference the target cell's frequency), and avoiding interference with adjacent operators or bands. This parameter is unrelated to subscriber database identifiers, alarm counts, or PRB utilization, all of which are tracked through entirely separate configuration management, fault management, or performance management mechanisms respectively.
NEW QUESTION # 45
Why does Nokia recommend configuring automatic session timeout (inactivity logout) for remote management sessions to AirScale base stations?
Answer: C
Explanation:
Automatic session timeout is a fundamental security control for remote management sessions. If an engineer leaves an authenticated session open and unattended - for example, stepping away from a workstation - anyone with physical or logical access to that workstation could potentially view sensitive configuration data or, more seriously, make unauthorized changes to a live base station, which could impact network stability, security, or subscriber service. Automatically terminating idle sessions after a defined inactivity period minimizes this exposure window. This control is unrelated to site power consumption and does not cause the base station itself to restart - only the management session is closed, while the BTS continues normal operation. It also has no effect on a cell's radio coverage area, which is determined entirely by RF design and configuration parameters such as transmit power and antenna settings.
