Nokia 5G RAN Network Operations Expert NRN-522 Prüfungsfragen mit Lösungen

1. 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

2. 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

3. 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

4. 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

5. 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
