質問 # 117
Why does NetAct support configuring automatic notifications, such as email or SMS, for Critical severity alarms to NOC personnel?
正解：A
解説：
NetAct supports configuring automatic notifications, such as email or SMS alerts, to be sent to designated NOC personnel when alarms of a certain severity - commonly Critical - are raised. This ensures severe issues are brought to the attention of responsible engineers promptly, even if no one is actively viewing the live FM dashboard at that exact moment, helping reduce the time between a fault occurring and corrective action beginning. This notification mechanism complements, rather than replaces, the FM dashboard, which remains necessary for detailed investigation, alarm correlation across the network, and ongoing monitoring of all severity levels. It does not automatically fix any underlying fault - it is purely an awareness mechanism - and has no effect on how many alarms the network actually generates, which is determined by real fault conditions and configured alarm definitions/thresholds, not by notification settings.

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?
正解：C
解説：
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.

What is the primary purpose of the Xn interface in a 5G RAN architecture?
正解：C
解説：
The Xn interface is the logical interface that connects neighboring gNBs (5G base stations) directly to one another, serving a role analogous to the X2 interface in 4G LTE. Its primary purpose is to support mobility- related signaling and data exchange between gNBs - most notably during handover procedures, where the source and target gNB use the Xn interface to coordinate the handover, exchange context information about the UE, and forward any buffered downlink user-plane data to minimize service interruption during the transition. The Xn interface can also carry information used for interference management and load balancing between neighboring cells. It is distinct from interfaces connecting the gNB to the core network (such as the NG interface), from intra-base-station interfaces like CPRI/eCPRI connecting baseband and RF units, and from the O and M connectivity used for software management, each of which serves a different architectural function within the overall RAN system.
質問 # 120
What is the key difference between a graceful restart and an immediate (forced) restart of a base station unit during maintenance activities?
正解：D
解説：
A graceful restart is designed to minimize the impact on active subscribers by allowing the system, where possible, to complete in-progress procedures or facilitate handovers of active sessions to neighboring cells before the restart actually takes effect, reducing the number of abruptly dropped connections. An immediate, or forced, restart proceeds without this consideration, restarting the unit right away regardless of any active sessions, which will be dropped as a result. NOC engineers may choose between these options depending on the urgency of the situation: a graceful restart is generally preferred for planned maintenance activities to minimize subscriber impact, while an immediate restart might be necessary in scenarios where a unit is unresponsive or where the urgency of resolving a critical fault outweighs the brief additional impact of dropped sessions. Neither option permanently disables the unit, and graceful restarts can be initiated remotely - they do not require physical power-cycling on site.
質問 # 121
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?
正解：B
解説：
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.
