質問 # 95
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.
質問 # 96
During a complex remote piloting activity involving multiple steps and risk of service impact, what additional coordination practice helps ensure accountability and a clear record of what was agreed and performed at each stage?
正解：A
解説：
For complex, multi-step remote piloting activities with potential service impact, using a shared communication channel - such as a bridge call or a logged chat/messaging channel - where each step, its confirmation, and its result are recorded in real time provides significant benefits. It creates a contemporaneous record of exactly what was instructed, performed, and confirmed at each stage, which supports accountability (clarifying who performed or authorized each action) and provides an accurate timeline that can be referenced if an issue arises during or after the activity, or if the activity needs to be reviewed afterward for process improvement. This is in addition to, not a replacement for, the final documentation in the maintenance ticket. Avoiding real-time communication would undermine the collaborative coordination that complex activities require; anonymous channels would defeat the accountability purpose; and performing steps simultaneously without sequencing would be unsafe and likely to cause errors, particularly where later steps depend on the successful completion of earlier ones.
質問 # 97
Following completion of a hardware replacement and remote piloting activity, which combination of checks represents the most complete final verification before the NOC engineer closes out the activity as successful?
正解：D
解説：
A complete final verification after a hardware replacement and remote piloting activity should confirm multiple dimensions of the site's restored operational state. This includes checking that alarms directly related to the replaced component and the maintenance activity itself have cleared as expected (with any remaining alarms understood and unrelated to the activity), confirming the affected cell has been unlocked and successfully returned to an in-service state, verifying that relevant communication links - such as CPRI
/eCPRI links to RF units or the AISG bus connection to antenna line devices - report normal status, and reviewing short-term performance indicators to confirm they are consistent with the site's established baseline, indicating the cell is performing as expected under real traffic. Only this combination provides genuine assurance that the activity was successful end-to-end. Administrative details like tool packing, serial number matching against shipping records (while useful for inventory purposes), and weather conditions do not address whether the network element is actually functioning correctly.
質問 # 98
After a field engineer replaces an RF unit, the NOC engineer observes that the eCPRI link between the baseband and the new RF unit remains down, even after the cell is unlocked. What should the NOC engineer do first?
正解：B
解説：
When an eCPRI (or CPRI) link remains down immediately following a physical hardware replacement, the most probable and easily verified cause is a physical-layer issue introduced during the replacement itself - such as a fiber connector not being fully seated, an SFP transceiver not properly inserted, a mismatched or faulty SFP module, or an incorrect port connection. Since the field engineer is already on site with direct physical access, the most efficient first step is to ask them to verify these physical connections before the NOC engineer invests time in deeper remote diagnostics, which would be premature given how common and simple physical connection issues are immediately after hardware work. Ordering a new baseband module is a significant escalation that should only follow ruling out simpler causes; locking the cell and closing the ticket would leave the site non-functional; and PLMN ID has no relationship to eCPRI link establishment, which operates at a lower layer entirely unrelated to network identity broadcasting.
質問 # 99
How does applying a software patch typically differ from performing a full software upgrade on a base station?
正解：C
解説：
A software patch is typically a smaller, targeted update designed to address specific known issues, bugs, or vulnerabilities within the currently running software baseline, without changing the overall feature set or version baseline significantly. Patches are often quicker to apply and may have a more limited scope of impact, making them suitable for addressing urgent issues between major release cycles. A full software upgrade, by contrast, replaces the base station's overall software load with a new baseline release, which may introduce new features, performance improvements, and an accumulated set of fixes - representing a more significant change that typically requires more thorough planning, testing, and a more comprehensive pre-change backup. Both patches and full upgrades can generally be delivered and activated remotely without requiring physical hardware replacement. Understanding this distinction helps NOC teams appropriately scope the risk, testing, and scheduling considerations for each type of software lifecycle activity.
