Nokia NRN-522 Test Engine Practice Test Questions, Exam Dumps [Q73-Q96]

NEW QUESTION 73
Why is it important for NOC personnel to establish a KPI baseline for each cell or site before evaluating whether current performance indicates a problem?

NEW QUESTION 74
How do NetAct and the AirScale BTS local Element Manager (Site Manager) typically relate to each other in day-to-day remote operations?

NEW QUESTION 75
In NetAct Performance Management, what is the standard default Result Output Period (ROP) used for collecting and reporting most cell-level performance measurement counters?

NEW QUESTION 76
What does an ‘Antenna Line Device (ALD) fault’ alarm on an AirScale cell typically indicate?

NEW QUESTION 77
For security segmentation, NOC personnel typically do not connect directly from their workstations to production AirScale base stations. Instead, they first authenticate to an intermediate, hardened host. What is this intermediate host commonly called?

NEW QUESTION 78
During a remote piloting activity, the NOC engineer and field engineer are unable to bring a replaced RF unit into service despite following standard verification and troubleshooting steps, and a hardware fault on the new unit itself is suspected. What is the most appropriate next step?

NEW QUESTION 79
A site reports a ‘Rectifier Fault’ or ‘DC Power Fault’ alarm together with multiple equipment alarms across different cabinets. What does the rectifier/DC power fault alarm relate to?

NEW QUESTION 80
The PLMN ID broadcast by a 5G cell is composed of which two elements, and what is its primary function?

NEW QUESTION 81
What is the key distinction between a full site backup and a partial (configuration-only) backup in the context of base station lifecycle management?

NEW QUESTION 82
A NOC engineer observes that a 5G cell’s average downlink user throughput has dropped significantly, but the cell’s PRB utilization remains low and no transport alarms are active. Which root cause is most consistent with these observations?

NEW QUESTION 83
A NOC engineer ‘acknowledges’ an active alarm in NetAct FM. What does this action signify?

NEW QUESTION 84
Before granting a new NOC engineer remote access credentials to production AirScale sites, what should be verified according to Nokia’s operational security practices?

NEW QUESTION 85
A NOC engineer reviewing UE measurement reports notices that two physically adjacent 5G cells are broadcasting the identical Physical Cell Identity (PCI), causing UEs to receive ambiguous reference signals.
What is this condition called, and what is the appropriate remote corrective action?

NEW QUESTION 86
A field engineer needs to work in close proximity to an antenna to replace a Tower Mounted Amplifier (TMA). What is the NOC engineer’s most important responsibility before the field engineer begins this work?

NEW QUESTION 87
A specific neighbor relation between Cell A and Cell B shows a consistently low handover success rate, while overall network-wide mobility KPIs remain healthy. What is the most appropriate first troubleshooting step?

NEW QUESTION 88
Before performing a remote software upgrade on a base station, what should a NOC engineer ensure has been completed regarding the site’s current state?

NEW QUESTION 89
Which statement correctly describes how OandM (management) traffic and user-plane traffic (e.g., NG-U/N3) are typically handled on the transport network connecting an AirScale BTS?

NEW QUESTION 90
A cell consistently shows PRB utilization above 90% during peak hours, along with a rising number of RRC Connection Rejections due to insufficient resources. What does this combination of indicators most strongly suggest?

NEW QUESTION 91
Before applying a significant parameter change to a live production cell, what best practice should a NOC engineer follow regarding the cell’s current configuration?

NEW QUESTION 92
Which AirScale management tool allows an engineer to connect directly to a single base station for local-level configuration viewing and diagnostics, as opposed to network-wide centralized management?

NEW QUESTION 93
When planning a maintenance window for a software activation affecting multiple cells at a site, which factor is most important for the NOC team to consider in order to minimize subscriber impact?

NEW QUESTION 94
A NOC engineer is investigating subscriber complaints of being unable to access data services even though their devices show a strong 5G signal and successfully camp on the cell. Which KPI should the engineer examine first to determine whether the issue lies in establishing the data bearer itself?

NEW QUESTION 95
A NOC engineer needs to recover a base station from a state where its parameter settings have been corrupted, but the underlying software load is functioning correctly. Which type of backup would be most directly applicable to resolving this specific issue?

NEW QUESTION 96
What is the AISG bus used for in the context of antenna line device management?
