질문 # 30
Before a field engineer disconnects and removes an RF unit for replacement, what action should the NOC engineer typically perform first?
정답：C
설명：
Before a field engineer physically disconnects an RF unit, the NOC engineer should administratively lock the affected cell(s). Locking puts the cell into a controlled, planned out-of-service state, which has several benefits: it allows UEs currently served by the cell to be handed over or to reselect to neighboring cells in an orderly manner before the disconnection occurs, and it ensures that when the RF unit is disconnected, the resulting alarms are correctly understood by the NOC and any monitoring systems as part of a planned maintenance activity rather than an unexpected fault requiring separate investigation or triggering unnecessary alerts/escalations. Increasing neighboring cells' power is not a standard or necessary preparatory step and could introduce interference; deleting the configuration would require a full re- commissioning afterward; and changing the PLMN ID would be both ineffective at preventing the brief outage and disruptive to network identification.
질문 # 31
A KPI tracks the percentage of established connections or sessions that end abnormally ('dropped') rather than through a normal release procedure. Which KPI category does this belong to?
정답：B
설명：
Retainability KPIs measure whether connections or sessions that have been successfully established remain stable and are terminated through normal procedures, rather than ending abnormally (a 'drop'). A high abnormal release/drop rate indicates retainability problems - subscribers may experience calls or data sessions ending unexpectedly mid-use, significantly impacting user experience even when the initial connection (accessibility) succeeded. This differs from Accessibility, which measures the success of the initial connection attempt; Mobility, which specifically measures handover performance; and Availability, which measures whether a cell or site is in service over time. Retainability degradation can result from radio link failures, interference, transport instability, or hardware issues affecting an already-active connection. NOC engineers monitoring retainability KPIs focus on the stability of in-progress sessions, a key contributor to overall subscriber-perceived quality of service.
질문 # 32
What is the role of the Managed Object Model (MOM) in Nokia's RAN configuration management framework?
정답：A
설명：
The Managed Object Model (MOM) defines the structured, hierarchical representation of all configurable entities within the network - such as network elements, their subordinate functional units, cells, and the individual parameters associated with each object - along with the relationships between them. Configuration management tools, including NetAct CM applications, rely on the MOM to know what objects exist, what parameters each object type supports, valid value ranges, and how objects relate to one another (for example, a cell object existing as a child of a baseband equipment object). Understanding the MOM is important for NOC engineers performing configuration changes, since it determines where a given parameter resides within the object hierarchy and what other objects or parameters might be affected by a change. The MOM is a configuration management construct and is unrelated to physical cabling documentation, alarm history (a fault management function), or software upgrade packages (a software lifecycle management function).
질문 # 33
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 # 34
After successfully completing a significant remote configuration change on a base station and confirming normal operation, what additional lifecycle management step should the NOC team perform?
정답：A
설명：
Once a significant configuration change has been successfully applied and verified - meaning the network element is operating normally with the new configuration in place - it is good practice to take an updated backup reflecting this new state. This becomes the new baseline restore point for any future changes, ensuring that if a subsequent change needs to be rolled back, the rollback target reflects the current, correct configuration rather than an outdated one that no longer matches the network element's intended state.
Restoring the previous backup immediately after a successful change would simply undo the work just completed, which is counterproductive. Deleting backups removes valuable recovery options and is contrary to good change management practice. Disabling the element's connection to NetAct would prevent the NOC from performing any future monitoring, fault management, or configuration activities on that element, which is operationally undesirable and unrelated to good post-change practice.
