質問 # 40
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：A
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.

A transport alarm 'Ethernet link down' is raised on the BTS-side interface toward the aggregation router. What is an appropriate FIRST remote action for the NOC engineer?
正解：D
解説：
When a transport-side alarm such as 'Ethernet link down' is raised on the BTS-facing interface toward the aggregation router, the appropriate first remote action is to investigate the physical and data-link layer status of that interface - checking link/port status, interface configuration such as speed and duplex settings and VLAN membership, and any visible cable/connector status indicators through management tools. If the issue appears to originate on the transport provider's side of the connection (such as a leased line or microwave link fault), coordinating with that provider is the next step. Only if remote checks cannot resolve the issue, or clearly indicate a physical hardware or cabling fault at the site, would on-site dispatch be considered.
Replacing the RF module addresses radio hardware, not a transport link fault, and modifying neighbor relations or cell bandwidth are RAN configuration changes that would not resolve a physical link failure.

What is the standard alarm severity ordering used in NetAct Fault Management, from highest to lowest severity?
正解：D
解説：
NetAct Fault Management follows the standard telecom alarm severity hierarchy: Critical, Major, Minor, and Warning, in descending order of severity. Critical alarms indicate a total or near-total loss of service, capability, or capacity, requiring immediate NOC action since they have the most severe impact on network availability and subscribers. Major alarms indicate serious degradation requiring prompt action, though typically with somewhat less urgency than Critical. Minor alarms represent non-service-affecting faults that should still be corrected to prevent future escalation into more serious issues. Warning alarms are generally informational or preventive, flagging conditions that could lead to a problem if left unaddressed but with no current service impact. Understanding this ordering is fundamental to NOC triage and prioritization: when multiple alarms appear on a dashboard, Critical alarms must be addressed first, followed by Major, Minor, and finally Warning, and this ordering underlies SLA-based response time commitments.
質問 # 43
What is the key distinction between a full site backup and a partial (configuration-only) backup in the context of base station lifecycle management?
正解：B
解説：
A full site backup typically captures both the currently running software load (or a reference to it) and the complete configuration data for the network element, providing the most comprehensive restore point - useful before major changes such as software upgrades or significant hardware-related maintenance. A partial, or configuration-only, backup captures just the configuration data - the set of parameters defining how the element is provisioned - without necessarily including the software image itself. Configuration-only backups are commonly used before smaller-scope parameter changes, where the software load itself is not expected to change, since they are typically faster to perform and require less storage. Choosing the appropriate backup type depends on the scope of the planned change: a software upgrade warrants a full backup, while a routine parameter adjustment may only require a configuration backup. Neither backup type is restricted to alarm history or performance counters, and both can typically be performed remotely without requiring a field engineer to be present.
質問 # 44
What does the NR-ARFCN (NR Absolute Radio Frequency Channel Number) represent in a 5G cell's configuration?
正解：C
解説：
The NR Absolute Radio Frequency Channel Number (NR-ARFCN) is a standardized numbering scheme defined for 5G NR that maps specific numeric values to corresponding carrier frequencies across the supported frequency range. When configuring a cell, the NR-ARFCN value (rather than specifying the frequency directly in MHz) is used to unambiguously identify the exact carrier frequency the cell will operate on, ensuring consistency across equipment from different vendors and alignment with regulatory frequency allocations. Correct NR-ARFCN configuration is essential for frequency planning, neighbor relation setup (since inter-frequency relations reference the target cell's frequency), and avoiding interference with adjacent operators or bands. This parameter is unrelated to subscriber database identifiers, alarm counts, or PRB utilization, all of which are tracked through entirely separate configuration management, fault management, or performance management mechanisms respectively.
