Nokia 5G RAN Network Operations Expert NRN-522 Prüfungsfragen mit Lösungen
How is the Cell Availability KPI typically calculated for a reporting period, and what does this KPI primarily reflect?
- A. (Total time the cell was in service / total time in the period) x 100 - reflects how much of the period the cell was able to carry traffic
- B. (Total successful handovers / total handover attempts) x 100 - reflects mobility performance
- C. (Total downlink throughput / total uplink throughput) x 100 - reflects traffic balance
- D. (Total active alarms / total cleared alarms) x 100 - reflects fault management efficiency

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?
- A. The personal contact details of subscribers who have filed complaints about the area
- B. The current cell configuration, recent alarm history, and relevant performance data (such as RSRP
/SINR distributions and throughput trends) for the affected cell and its neighbors - C. A list of unrelated sites located in a different region of the country
- D. The original purchase invoice for the site's equipment

A NOC engineer 'acknowledges' an active alarm in NetAct FM. What does this action signify?
- A. The affected base station will automatically reboot
- B. The underlying fault has been automatically repaired
- C. The alarm has been seen and is being handled, helping avoid duplicated investigation by other team members
- D. The alarm record is permanently deleted from the system

During PCI planning for a dense cluster of 5G cells, why is it important to avoid assigning PCI values that result in the same PCI modulo group (such as the same PCI mod 3 value) to closely located neighboring cells?
- A. Because PCI mod 3 values determine the cell's maximum allowed bandwidth
- B. Because PCI mod values determine which software version each cell can run
- C. Because cells sharing the same PCI mod 3 group transmit certain reference signal sequences on the same resource elements, which can cause increased reference signal interference between those cells
- D. Because cells with the same PCI mod 3 value cannot be included in the same Tracking Area

When planning the channel bandwidth and subcarrier spacing for a 5G cell, what is the primary operational impact of these parameters?
- A. They determine the number of available Physical Resource Blocks (PRBs), which directly affects the cell's total capacity for scheduling user traffic
- B. They determine the encryption algorithm used for OandM traffic to the cell
- C. They determine which alarm severities are enabled for the cell
- D. They determine the cell's PLMN ID and Tracking Area Code
