                      Nokia 5G RAN Network Operations Expert Sample Questions:

                      Question 1

                      A transport alarm 'Ethernet link down' is raised on the BTS-side interface toward the aggregation router. What is an appropriate FIRST remote action for the NOC engineer?

                      A. Modify the cell's neighbor relation list
                      B. Increase the configured cell bandwidth
                      C. Replace the RF module at the site
                      D. Check the physical/data-link layer status and interface configuration of that port, and coordinate with the transport provider if needed before considering on-site dispatch


                      Question 2

                      What is the primary purpose of the secure IPsec VPN tunnel established between a centralized Operations Center and a remote 5G site's transport network?

                      A. To compress software packages before download
                      B. To replace the need for alarm monitoring
                      C. To boost the radio transmit power of the cell
                      D. To encrypt and authenticate OandM traffic exchanged between NetAct/NOC and the base station


                      Question 3

                      A NOC team uses NetAct to download a new software package to a group of base stations during business hours, but schedules the activation of that software for later that night. What is the primary operational benefit of this 'download now, activate later' approach?

                      A. Downloading the software automatically restarts the base station immediately, so timing has no operational significance
                      B. It allows the time-consuming file transfer to occur without impacting current service, while the service- impacting activation (which typically requires a restart) is deferred to a low-traffic maintenance window
                      C. It permanently removes the need to take any backups before activation
                      D. Activation always occurs automatically the instant the download completes, regardless of scheduling


                      Question 4

                      A NOC engineer is considering performing a remote factory reset on a base station as a troubleshooting step for a persistent issue. What is the most significant risk of this action if performed without proper preparation?

                      A. A factory reset automatically creates a new backup of the current configuration before proceeding
                      B. A factory reset may erase the unit's current configuration, requiring a full restoration from backup (or re- commissioning) to return the site to its operational state
                      C. A factory reset has no effect on the unit's configuration and is therefore always safe to perform
                      D. A factory reset only affects the unit's physical LED indicators and has no impact on service


                      Question 5

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

                      A. NetAct manages only 2G/3G technologies, while the Element Manager manages only 5G
                      B. NetAct eliminates any need for local element-level management tools
                      C. The Element Manager centrally manages multiple base station sites across the network
                      D. NetAct provides centralized, network-wide OAM, while the Element Manager provides detailed, element-specific local access for in-depth diagnostics
