                      Nokia 5G RAN Network Operations Expert Sample Questions:

                      1. What operational benefit does the Automatic Neighbor Relation (ANR) function provide to a NOC team managing 5G RAN configuration?

                      A) It automatically increases a cell's transmit power whenever coverage gaps are detected
                      B) It automatically changes the PLMN ID of a cell when roaming agreements change
                      C) It automatically resolves all hardware faults on RF units without engineer intervention
                      D) It automatically detects neighboring cells based on UE measurement reports and establishes or updates neighbor relations without requiring manual configuration of each relation


                      2. Why is it important for the NOC engineer to confirm the affected cell is locked and showing as out-of-service (in a planned state) before instructing the field engineer to disconnect any RF cabling at the antenna?

                      A) Locking the cell increases its transmit power to assist the field engineer's measurements
                      B) Confirming the planned out-of-service state ensures the disconnection is performed on a cell that is not actively carrying traffic, supporting both safety and avoiding an unplanned service-impacting fault condition
                      C) Locking the cell changes the site's PLMN ID to prevent any UEs from being registered anywhere on the network
                      D) Locking the cell automatically dispatches a replacement part to the site


                      3. How is the Cell Availability KPI typically calculated for a reporting period, and what does this KPI primarily reflect?

                      A) (Total downlink throughput / total uplink throughput) x 100 - reflects traffic balance
                      B) (Total active alarms / total cleared alarms) x 100 - reflects fault management efficiency
                      C) (Total successful handovers / total handover attempts) x 100 - reflects mobility performance
                      D) (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


                      4. During a Site Acceptance Test (SAT) for a newly commissioned 5G site, what is the NOC team's typical role?

                      A) To physically inspect the antenna mounting hardware for structural compliance
                      B) To remotely verify that the site is visible and manageable from centralized OandM systems, that cells come into service correctly, that no unexpected alarms are present, and that initial performance indicators are within expected ranges
                      C) To install the physical RF cabling between the antenna and the baseband unit
                      D) To negotiate the commercial contract terms for the site's construction


                      5. After a field engineer installs a brand-new RET unit (not a like-for-like replacement, but a new addition to the antenna line) and connects it to the AISG bus, what initial remote action does the NOC engineer typically need to perform to bring the device under management?

                      A) Physically relocate the baseband unit to a different rack position
                      B) Perform an AISG device scan/discovery to detect the new device on the bus and then configure it within the system so it can be monitored and controlled
                      C) Change the cell's Tracking Area Code to match the RET unit's serial number
                      D) Manually rewrite the base station's entire software image
