NEW QUESTION # 43
NetAct reports the transport link to a remote 5G site as 'up', but the NOC engineer still cannot establish an OandM session to the AirScale BTS. What is the MOST appropriate next troubleshooting step?
Answer: B
Explanation:
When basic transport/IP connectivity to a site is confirmed as up but an O and M management session still cannot be established, the issue is likely at a higher layer than physical or network-layer reachability.
Common causes include expired or mismatched security certificates, incorrect login credentials, or a misconfigured O and M IP address or management VLAN on the base station itself. A layered troubleshooting approach moves from transport, to network, to application/management-layer checks once lower layers are confirmed functional. Replacing the RF module addresses a hardware radio issue, not an O and M session
/authentication problem, and would be premature without further evidence. Adjusting reference signal power is unrelated to management connectivity. Restarting the entire NetAct server is a drastic action affecting the whole managed network and is never an appropriate first response to a single-site connectivity issue.
NEW QUESTION # 44
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 # 45
During a remote piloting session, what communication practice is most important for the NOC engineer and field engineer to follow to ensure tasks are completed safely and correctly?
Answer: B
Explanation:
Effective remote piloting depends on clear, step-by-step communication where each action - whether performed by the field engineer physically or the NOC engineer remotely - is confirmed as complete before the next dependent step proceeds. This sequential confirmation approach ensures that both parties maintain an accurate, shared understanding of the site's current state at every point in the procedure, which is critical for both safety (for example, confirming a cell is locked before physical work begins near an antenna) and technical correctness (for example, confirming a physical connection has been made before the NOC engineer attempts to verify it remotely). Providing all instructions upfront without ongoing confirmation risks steps being missed, performed out of order, or performed before prerequisite conditions are met. Relying solely on non-real-time communication such as email is impractical for time-sensitive coordination, and allowing the field engineer to proceed entirely independently removes the collaborative verification that makes remote piloting effective and safe.
NEW QUESTION # 46
Which statement correctly distinguishes 'Integrity' KPIs from 'Accessibility' KPIs in RAN performance management?
Answer: D
Explanation:
Accessibility KPIs measure how successfully a UE can initially establish a connection or session when it attempts to do so - for example, RRC Connection Setup Success Rate. Integrity KPIs, by contrast, measure the quality and performance of a connection once it has been successfully established - for example, achievable throughput, latency, or error rates during an active session. These represent two distinct stages of user experience: first, can the user connect at all (Accessibility), and second, once connected, how good is the service (Integrity)? They are not the same category measured differently, since they address fundamentally different performance aspects and often require different troubleshooting approaches - accessibility issues often relate to admission and signaling procedures, while integrity issues often relate to radio conditions, interference, or capacity affecting data transfer. Integrity KPIs apply across all radio generations including
5G, and Accessibility is not limited solely to throughput.
NEW QUESTION # 47
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: B
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.
