When a software package is transferred to a base station via SFTP as part of a remote software delivery, what is the purpose of performing a checksum verification on the downloaded file before activation?
正解：C
解説：
A checksum (or hash value) verification compares a calculated value derived from the downloaded software file against an expected reference value provided by the software source. If the values match, this confirms that the file was transferred completely and without corruption or unauthorized modification during the transfer process - which is particularly important for large software images transferred over networks where transient errors, interruptions, or transmission issues can occasionally cause partial or corrupted downloads.
Activating a software package from a corrupted or incomplete file could lead to activation failures, unpredictable behavior, or a unit that fails to return to normal operation - even before any compatibility or configuration considerations come into play. Checksum verification is a foundational integrity check performed as part of the software delivery process and has no relationship to programming language translation, geographic location determination, or performance KPI calculations, which are entirely unrelated functions.

A specific neighbor relation between Cell A and Cell B shows a consistently low handover success rate, while overall network-wide mobility KPIs remain healthy. What is the most appropriate first troubleshooting step?
正解：D
解説：
Because the issue is isolated to a single neighbor relation rather than affecting overall network mobility, the problem is most likely localized to the configuration between these two specific cells rather than a broader hardware, transport, or core network fault - which would typically affect multiple relations or KPIs more broadly. The appropriate first step is to review the neighbor relation configuration, including parameters such as handover thresholds, measurement gap settings, frequency relations, and Automatic Neighbor Relation (ANR) data, to confirm the relation is correctly defined and that measurement configurations align with actual RF conditions between the two cells. Misconfigured handover thresholds, missing or incorrect frequency information, or an outdated neighbor list entry are common causes of localized handover failures.
Restarting hardware, rebooting core elements, or adjusting power network-wide are disproportionate actions that risk impacting unrelated cells and do not target the specific, isolated nature of the reported problem.
質問 # 80
A cell consistently shows PRB utilization above 90% during peak hours, along with a rising number of RRC Connection Rejections due to insufficient resources. What does this combination of indicators most strongly suggest?
正解：C
解説：
Sustained PRB utilization above roughly 90% indicates that nearly all available radio resources in the cell are being consumed, leaving little headroom for new connections or additional traffic. When this is combined with an increasing rate of RRC Connection Rejections specifically attributed to insufficient resources, it strongly indicates that the cell's admission control function is actively rejecting new connection attempts because demand exceeds available capacity - a clear signature of capacity congestion during busy periods.
This is fundamentally different from a hardware fault (which would typically generate equipment alarms and affect availability rather than just capacity), a synchronization loss (which affects timing-sensitive operations and often triggers specific sync alarms), or a neighbor relation issue (which would primarily affect mobility KPIs). Recognizing this pattern is important because it points toward capacity planning actions - such as carrier expansion, load balancing, or additional sectorization - rather than fault remediation.
質問 # 81
Accessibility KPIs such as RRC Connection Setup Success Rate drop sharply for a single cell, while neighboring cells remain normal. What should the NOC engineer check FIRST?
正解：D
解説：
When accessibility KPIs such as RRC Connection Setup Success Rate drop sharply for one specific cell while neighboring cells remain normal, the most productive investigation focuses on factors specific to that cell:
reviewing recent alarms (hardware, transport, or synchronization faults affecting only that cell) and checking the configuration management audit trail for any recent parameter change, neighbor relation update, or feature activation that coincided with the KPI drop. Because the issue is localized to a single cell rather than affecting the surrounding area broadly, it is unlikely to be caused by something network-wide such as handset operating system versions used nationwide, and it is entirely unrelated to the billing system or NetAct dashboard appearance settings. Correlating the timing of the KPI degradation with that cell's alarm history and recent CM changes is a standard, effective root-cause approach for localized accessibility issues.
質問 # 82
Which alarm severity level generally requires the MOST urgent NOC response under standard SLA-based prioritization?
正解：C
解説：
In the standard alarm severity model used across telecom Fault Management systems, including NetAct, Critical alarms represent the highest severity, typically indicating a total or near-total loss of service, capability, or capacity with immediate and significant impact on subscribers - for example, a complete cell or site outage. Because of this severe impact, Critical alarms require the most urgent NOC response and are governed by the tightest response and resolution timeframes among all severity levels in most operational SLAs. Major alarms indicate serious degradation requiring prompt, though slightly less immediate, action.
Minor alarms represent non-service-affecting issues that should be addressed to prevent escalation, and Warning alarms are typically informational or preventive, requiring the least urgency. Correctly prioritizing Critical alarms above all others ensures NOC resources focus first on the issues with the greatest impact on network availability and customer experience.
