NEW QUESTION # 20
A NOC engineer 'acknowledges' an active alarm in NetAct FM. What does this action signify?
Answer: C
Explanation:
Acknowledging an alarm in NetAct FM is an administrative action that marks the alarm as having been seen and taken ownership of by an engineer, without changing the underlying fault condition itself. In a NOC environment where multiple engineers or shifts monitor shared alarm lists, acknowledgement communicates that someone is already aware of and working on the issue, helping to avoid duplicated troubleshooting effort and providing a basic accountability trail for follow-up. It does not automatically resolve or repair the underlying fault - the alarm will only clear once the actual condition causing it is resolved, whether automatically by the network recovering or through engineer intervention. Acknowledgement also does not cause the base station to reboot, and acknowledged alarms remain visible in the active list (not deleted) until the underlying condition clears, at which point they typically move to the alarm history.
NEW QUESTION # 21
A NOC engineer wants to confirm that a newly installed AirScale BTS has completed commissioning and is ready to carry live traffic. Which indicator provides this confirmation?
Answer: B
Explanation:
Commissioning brings a newly installed AirScale BTS under NetAct management, loads the correct software and configuration, and activates its cells. The definitive operational confirmation that commissioning is complete and the site is ready for live service is that the relevant cells show an unlocked (administratively enabled) state combined with an operational 'in service'/available status in NetAct, and there are no outstanding blocking faults or critical alarms preventing service. This combination of administrative and operational state, together with a clean alarm list, is what NOC engineers check before confirming a site is live. Appearing on a mapping tool, having fiber physically installed by the transport provider, or having power equipment installed are all useful prerequisite facts about the site's physical readiness, but none of them confirm that the RAN equipment itself has successfully completed commissioning and is carrying traffic.
NEW QUESTION # 22
An operator is considering reducing the PM Result Output Period (ROP) for a set of cells from 15 minutes to
1 minute to enable near real-time troubleshooting. What is the most significant operational trade-off of this change?
Answer: C
Explanation:
Reducing the Result Output Period increases the frequency at which performance counters are collected, processed, and stored, which proportionally increases the volume of measurement data generated by each network element. Moving from a 15-minute to a 1-minute ROP, for example, would generate roughly fifteen times more data points over the same time period. This places significantly higher demand on the file transfer, processing, and storage capacity of NetAct and any downstream analytics systems, and can also increase signaling and processing load on the base stations themselves. While finer granularity can be valuable for short-term, targeted troubleshooting of a specific cell during an active investigation, it is not typically sustainable as a network-wide, long-term configuration. KPI formulas remain valid regardless of ROP, alarm notifications are a separate mechanism unaffected by PM ROP settings, and historical trending remains possible - it simply involves more granular data points.
NEW QUESTION # 23
Why do NOC teams typically schedule software activation activities - which require a base station restart - for late-night or off-peak hours rather than during the day?
Answer: A
Explanation:
Activating new software on a base station typically requires the affected unit (or units) to restart, which causes a brief interruption to service for any UEs connected through that cell during the restart. To minimize the impact of this unavoidable interruption, NOC teams schedule such activities during maintenance windows that coincide with periods of lowest network traffic - commonly late at night or in the early morning hours - when the fewest subscribers are likely to be actively using the network. This reduces the number of dropped sessions and the overall visibility of the brief outage to end users. There is no technical restriction preventing restarts during daylight hours, nor does activation duration meaningfully change based on time of day, and NetAct does not impose a blanket restriction on when configuration changes can be submitted - the scheduling decision is an operational best practice driven by minimizing customer impact, not a technical limitation.
NEW QUESTION # 24
Before a field engineer disconnects and removes an RF unit for replacement, what action should the NOC engineer typically perform first?
Answer: D
Explanation:
Before a field engineer physically disconnects an RF unit, the NOC engineer should administratively lock the affected cell(s). Locking puts the cell into a controlled, planned out-of-service state, which has several benefits: it allows UEs currently served by the cell to be handed over or to reselect to neighboring cells in an orderly manner before the disconnection occurs, and it ensures that when the RF unit is disconnected, the resulting alarms are correctly understood by the NOC and any monitoring systems as part of a planned maintenance activity rather than an unexpected fault requiring separate investigation or triggering unnecessary alerts/escalations. Increasing neighboring cells' power is not a standard or necessary preparatory step and could introduce interference; deleting the configuration would require a full re- commissioning afterward; and changing the PLMN ID would be both ineffective at preventing the brief outage and disruptive to network identification.
