질문 # 95
What is the primary purpose of the Tracking Area Code (TAC) configured on a 5G cell?
정답：D
설명：
The Tracking Area Code (TAC) is a configuration parameter that groups one or more cells into a Tracking Area, which the core network uses to manage UE location tracking while a device is in idle mode. When a UE moves between cells within the same Tracking Area, it does not need to perform a tracking area update, reducing signaling overhead. When a UE moves to a cell with a different TAC, it triggers a tracking area update procedure so the core network knows which area to page the UE in when there is incoming traffic.
Proper TAC planning is important: areas that are too large can increase paging load across many cells, while areas that are too small can increase signaling load from frequent tracking area updates. TAC has no relationship to hardware vendor identification, transmit power limits, or software versioning, which are configured and managed through entirely separate parameters and processes.
질문 # 96
Which of the following best describes 'fault isolation' as performed by NOC technical support before deciding whether to dispatch a field engineer?
정답：D
설명：
Fault isolation is the systematic process by which NOC technical support narrows down the likely location and cause of a fault using all available remote diagnostic information, before deciding whether a remote fix is possible or a field dispatch is required. This includes reviewing active alarms and their correlation (distinguishing root-cause from symptom alarms), examining relevant performance management data for anomalies, checking the status of interfaces between functional domains such as baseband-to-RF links or transport interfaces, and reviewing element logs where available. The goal is to determine whether the fault most likely resides in the baseband processing unit, an RF module, the transport network, or an external
/environmental factor such as power or cooling, so that any field dispatch is properly scoped with the correct parts, tools, and instructions. Randomly replacing components, assuming a full rebuild is always needed, or ignoring correlation data are inefficient approaches that proper fault isolation is designed to avoid.
질문 # 97
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：B
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.
질문 # 98
Which KPI category do uplink and downlink packet loss rate counters primarily contribute to, and why are they operationally significant for a NOC team?
정답：B
설명：
Packet loss rate counters fall under the Integrity KPI category, which focuses on the quality and reliability of service delivered to users during an active connection, as opposed to whether a connection can be established (Accessibility), maintained without dropping (Retainability), handed over successfully (Mobility), or whether the cell is operational at all (Availability). High packet loss directly degrades user experience for real-time applications such as voice, video, and gaming, and can also trigger retransmissions that further increase congestion and reduce effective throughput. For a NOC team, monitoring packet loss trends is operationally significant because sustained increases often correlate with transport network issues (such as congestion or errors on backhaul links), radio interference causing high error rates, or hardware degradation. Identifying and addressing rising packet loss early helps prevent broader service quality complaints and supports proactive maintenance before the issue escalates into accessibility or retainability problems.
질문 # 99
A remote 5G site has redundant transport paths (primary and backup) providing OandM connectivity to NetAct. What is the main operational benefit of this redundancy?
정답：C
설명：
Providing dual or redundant transport paths for O and M connectivity increases the resilience of remote management. If the primary backhaul link fails - for example, due to a fiber cut or a microwave link outage - the base station can continue to report alarms and performance data, and remain reachable for configuration changes via the secondary path, preserving the Operations Center's visibility and control without requiring a site visit purely to restore management connectivity. This redundancy specifically benefits the continuity of monitoring and management functions. It has no effect on a cell's radio coverage area, which depends on RF design parameters such as transmit power, antenna configuration, and frequency band, nor does it relate to spectrum-sharing arrangements between operators. It also does not eliminate the ongoing need for periodic software updates and patching, which remain a separate lifecycle management activity.
