최신 Nokia 5G NRN-522 무료샘플문제 (Q92-Q97):

질문 # 92
A NOC engineer 'acknowledges' an active alarm in NetAct FM. What does this action signify?

정답：C

설명：
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.


질문 # 93
In NetAct Performance Management, what is the standard default Result Output Period (ROP) used for collecting and reporting most cell-level performance measurement counters?

정답：B

설명：
The default Result Output Period (ROP) for performance management counters in Nokia's RAN solution is 15 minutes. This interval provides a practical balance between granularity and system load: it is short enough to allow NOC engineers to detect emerging issues, congestion trends, and KPI fluctuations close to real time, while not generating an unmanageable volume of measurement data that would overwhelm storage and processing resources in NetAct. Fifteen-minute granularity is widely used as the basis for accessibility, retainability, mobility, integrity, and availability KPI formulas, and is the standard interval referenced in performance dashboards and automated reports. While other reporting intervals (such as 1 hour or 24 hours) can be configured for specific measurement jobs or long-term trend analysis, the 15-minute ROP remains the operational baseline for day-to-day RAN performance monitoring and troubleshooting activities performed by remote operations teams.


질문 # 94
A field team is planning a site visit to investigate a persistent coverage issue and requests information from the NOC to help prepare. What information can the NOC engineer most usefully provide to support this site survey?

정답：C

설명：
When a field team is preparing to investigate a persistent coverage issue, remotely available operational data can significantly improve the efficiency and focus of their site visit. The NOC engineer can provide the current configuration of the affected cell (including parameters such as transmit power, tilt settings, and azimuth where available), a review of recent alarm history to identify any recurring or unresolved fault indications, and relevant performance data such as RSRP/SINR distributions and throughput trends, which can help characterize the nature of the coverage issue (for example, distinguishing a coverage gap from an interference problem) before the field team arrives. This context allows the field team to prioritize their investigation - for example, focusing on antenna alignment if tilt/azimuth data looks unusual, or focusing on potential external interference sources if SINR is poor despite adequate RSRP. Subscriber personal information, equipment purchase records, and data about unrelated sites would not provide relevant technical context for this investigation.


질문 # 95
A NOC engineer observes an 'alarm storm' - dozens of alarms appearing within seconds across multiple cells served by the same site. What is the MOST likely explanation?

정답：A

설명：
An 'alarm storm' - many alarms appearing across multiple cells at a single site within a short window - is a classic indicator that a shared resource serving all of those cells has failed. Multiple cells at a site commonly depend on the same System Module (baseband), the same transport connection back to the aggregation/core network, the same power supply, or the same synchronization source; a failure in any one of these shared elements can simultaneously impact every dependent cell, producing a burst of correlated alarms.
Recognizing this pattern allows the NOC engineer to search for a single common-cause fault - for example, a transport outage or System Module failure - rather than treating each cell's alarms as independent issues requiring separate investigation. It is extremely unlikely that multiple independent hardware faults occur simultaneously by coincidence, and such patterns should never be dismissed as a routine NetAct bug or simply ignored.


질문 # 96
Which KPI category do uplink and downlink packet loss rate counters primarily contribute to, and why are they operationally significant for a NOC team?

정답：B

설명：
Packet loss rate counters fall under the Integrity KPI category, which focuses on the quality and reliability of service delivered to users during an active connection, as opposed to whether a connection can be established (Accessibility), maintained without dropping (Retainability), handed over successfully (Mobility), or whether the cell is operational at all (Availability). High packet loss directly degrades user experience for real-time applications such as voice, video, and gaming, and can also trigger retransmissions that further increase congestion and reduce effective throughput. For a NOC team, monitoring packet loss trends is operationally significant because sustained increases often correlate with transport network issues (such as congestion or errors on backhaul links), radio interference causing high error rates, or hardware degradation. Identifying and addressing rising packet loss early helps prevent broader service quality complaints and supports proactive maintenance before the issue escalates into accessibility or retainability problems.
