질문 # 23
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?
정답：A
설명：
For security, isolation, and quality-of-service reasons, AirScale base stations typically separate Operations and Maintenance (O and M) traffic from user-plane traffic (such as NG-U/N3 in 5G or S1-U in 4G) using distinct VLANs and/or IP addressing on the transport network. This separation ensures that configuration commands, alarm reporting, and software transfers travel on a logically isolated path from subscriber data, reducing the risk that issues or attacks affecting the user-plane path could impact management connectivity, and allowing each traffic type to be independently prioritized and monitored. It is incorrect that they must share identical addressing, that O and M cannot use IP (modern AirScale O and M is IP-based and typically carried over the same physical transport with logical separation), or that user-plane traffic configuration is unrelated to transport - transport interface parameters configured via NetAct CM directly determine how user-plane traffic is carried.
질문 # 24
A cell repeatedly raises and clears 'Cell Unavailable' alarms. Performance data shows PRB utilization dropping to zero during exactly the same periods. Which area should be investigated FIRST as the likely root cause?
정답：B
설명：
When a cell repeatedly raises and clears 'Cell Unavailable' alarms, and PRB utilization simultaneously drops to zero during exactly those same intervals, this pattern strongly indicates the cell is genuinely going out of service intermittently, rather than a display or reporting artifact. The investigation should focus on causes capable of producing repeated, short-duration outages: transport link instability (brief link flaps causing loss of the cell's connectivity), loss of synchronization reference (particularly significant for TDD 5G, where sync loss can force a cell to stop transmitting to avoid interference), or unexpected hardware resets/restarts of the baseband or radio unit, potentially linked to environmental issues such as overheating or power fluctuations.
NetAct UI theme settings, subscriber handset models, and the billing system are entirely unrelated to RAN service availability and would not explain this correlated alarm and KPI pattern. Correlating alarm timing with PM data and environmental/transport alarms is a key NOC diagnostic technique.
질문 # 25
A NOC engineer notices that UEs in a cell are triggering handovers to a neighboring cell and then quickly handing back, repeating this cycle (a 'ping-pong' pattern). Which parameter adjustment is most likely to help reduce this behavior?
정답：D
설명：
Ping-pong handovers occur when a UE repeatedly hands over back and forth between two cells, often because the signal levels of both cells are very close to each other near the cell boundary, causing the handover trigger condition to be met in alternating directions in quick succession. Handover events (such as an A3 event, where a neighbor's signal becomes a defined offset better than the serving cell) include configurable hysteresis and time-to-trigger parameters. Increasing the hysteresis margin requires a more substantial and sustained signal difference before a handover is triggered, while increasing the time-to- trigger requires the condition to be met for a longer continuous duration before the measurement report is sent. Both adjustments reduce sensitivity to short-term signal fluctuations, directly addressing ping-ponging.
Disabling the neighbor relation would prevent legitimate handovers entirely, harming mobility performance; changing PCI values or bandwidth does not address the underlying signal-level trigger sensitivity that causes ping-pong behavior.
질문 # 26
Which Nokia centralized network management system is primarily used by NOC and technical support personnel to monitor, configure, and manage AirScale 5G base stations remotely from an Operations Center?
정답：C
설명：
NetAct is Nokia's centralized Operations Support System (OSS) and is the primary platform used by NOC and technical support teams to manage AirScale 5G base stations from a centralized Operations Center. It integrates Fault Management (FM), Configuration Management (CM), Performance Management (PM), and Software Management (SWM) modules into a single environment, allowing engineers to monitor alarms, push configuration changes, review KPI dashboards, and manage software lifecycle activities across the entire RAN estate without visiting individual sites. While element-level tools such as BTS Site Manager exist for local diagnostics on a single base station, NetAct is the day-to-day platform for remote, network-wide operations. NetGuard focuses on security analytics, CloudBand on NFV infrastructure orchestration, and Nokia Digital Automation Cloud targets private wireless deployments, so none of these serve as the primary RAN operations management system referenced in remote operations procedures.
질문 # 27
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?
정답：D
설명：
When a new Antenna Line Device such as a RET unit is physically connected to the AISG bus for the first time, it is not automatically recognized and managed by the base station's O and M system without an initial discovery step. The NOC engineer typically needs to initiate an AISG device scan (discovery process), which queries the bus for connected devices and identifies the new RET unit, retrieving its device information. Once discovered, the device needs to be configured within the management system - associating it with the correct antenna/sector and ensuring its parameters (such as tilt range limits) are properly set - so that it becomes a manageable object that can be monitored for status and controlled for tilt adjustments going forward. This process is entirely software/configuration-based and remote; it does not involve rewriting the base station's overall software image, modifying unrelated identifiers like Tracking Area Code, or any physical relocation of equipment.
