질문 # 32
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：A
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 # 33
Handover Success Rate is a KPI primarily used to assess which aspect of network performance?
정답：B
설명：
Handover Success Rate measures the percentage of handover attempts - where a UE's connection is transferred from one cell to another, typically as the subscriber moves through the coverage area - that complete successfully without dropping the connection. This KPI falls under the Mobility category of performance management, which assesses how effectively the network maintains service continuity as users move, including intra-frequency, inter-frequency, and inter-RAT mobility procedures such as those involved in 4G-to-5G EN-DC configurations. Poor handover success rates can result from issues such as incorrect or missing neighbor relations, insufficient coverage overlap between cells, interference, or misconfigured handover thresholds and parameters. This KPI is unrelated to software version compliance (tracked through software inventory and management), backup file integrity (a software lifecycle concern), or NetAct license utilization (an administrative matter) - it is specifically a mobility indicator used to detect handover-related degradation affecting users in motion.
질문 # 34
What is the AISG bus used for in the context of antenna line device management?
정답：D
설명：
The Antenna Interface Standards Group (AISG) bus is a standardized communication interface (typically layered over RS-485 and sometimes carried over the same coaxial feeder cable as the RF signal, using a technique that separates the control signal from the RF) that enables the base station's control unit to discover, communicate with, and control Antenna Line Devices (ALDs) mounted on or near the antenna - most commonly Remote Electrical Tilt (RET) actuators and Tower Mounted Amplifiers (TMAs). Through the AISG bus, the system can remotely query device status, read sensor data such as current tilt position, and send control commands such as tilt adjustments or TMA gain settings. This is entirely distinct from the CPRI
/eCPRI fiber links carrying baseband-to-RF digital radio signals, the O and M IP network connecting the site to centralized management systems like NetAct, or the DC power distribution supplying equipment - each of which serves a different, non-overlapping function within the site's overall infrastructure.
질문 # 35
Before applying a significant parameter change to a live production cell, what best practice should a NOC engineer follow regarding the cell's current configuration?
정답：D
설명：
Taking a configuration backup or snapshot of the current parameter settings before applying a significant change is a fundamental change management best practice. If the new configuration causes unexpected behavior - such as degraded KPIs, connectivity issues, or unintended interactions with other parameters - having a known-good baseline allows the engineer to quickly roll back to the previous configuration, minimizing service impact and downtime while the root cause is investigated. While some configuration management tools may offer change history or versioning features, relying solely on this without an explicit pre-change backup is risky, and the assumption that changes are always automatically and fully reversible is incorrect. Deleting the existing configuration before applying a new one is highly disruptive and would cause an outage. Disabling alarm reporting during a change is dangerous, as it would prevent the NOC from detecting genuine problems introduced by the change itself, undermining the very monitoring needed to assess the change's impact.
질문 # 36
A NOC team is investigating a degradation in E-RAB / QoS flow setup success rate for a specific gNB.
Which approach is MOST effective for identifying the root cause?
정답：B
설명：
Investigating a degradation in E-RAB or 5G QoS flow setup success rate for a specific gNB is most effectively approached by correlating multiple data sources covering the affected time period: checking active alarms on that gNB (hardware, transport, or signaling faults), reviewing the configuration management audit trail for any recent parameter change that coincided with the degradation, and examining relevant performance counters such as resource availability/congestion indicators, transport interface statistics, and signaling success/failure counts. This multi-source correlation identifies whether the degradation stems from a hardware fault, a configuration error, a capacity constraint, or a transport issue, enabling targeted remediation. Reviewing only high-level summary reports lacks the technical granularity required. Restarting NetAct is a drastic, unfocused action unrelated to a single gNB's issue and risks disrupting network-wide monitoring. Assuming the cause is always subscriber devices, without first checking network-side data, skips the most relevant and controllable areas of investigation.
