問題 #22
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?
答案：C
解題說明：
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.
問題 #23
After a field engineer completes a baseband module replacement and confirms physical installation is complete, which set of remote checks should the NOC engineer perform to verify successful restoration of service?
答案：B
解題說明：
After a baseband module replacement, comprehensive remote verification is essential to confirm the site has been fully restored to normal operation before the maintenance activity is considered complete. This includes unlocking the affected cell(s) and confirming they successfully return to an in-service state without generating new critical or major alarms (beyond any expected transient alarms during the restart process), verifying that the CPRI or eCPRI links between the new baseband module and the connected RF units are established and reporting normal status (confirming correct physical connectivity and configuration), and monitoring relevant KPIs over a short period to confirm they return to levels consistent with the site's historical baseline, indicating the cell is performing as expected. Relying on indicator lights alone, simply confirming the field engineer's departure, or expecting a PCI change (which would not normally occur as a result of a hardware replacement) would all fail to provide meaningful assurance that the site is fully operational.
問題 #24
Which statement correctly describes how OandM (management) traffic and user-plane traffic (e.g., NG-U/N3) are typically handled on the transport network connecting an AirScale BTS?
答案：D
解題說明：
For security, isolation, and quality-of-service reasons, AirScale base stations typically separate Operations and Maintenance (O and M) traffic from user-plane traffic (such as NG-U/N3 in 5G or S1-U in 4G) using distinct VLANs and/or IP addressing on the transport network. This separation ensures that configuration commands, alarm reporting, and software transfers travel on a logically isolated path from subscriber data, reducing the risk that issues or attacks affecting the user-plane path could impact management connectivity, and allowing each traffic type to be independently prioritized and monitored. It is incorrect that they must share identical addressing, that O and M cannot use IP (modern AirScale O and M is IP-based and typically carried over the same physical transport with logical separation), or that user-plane traffic configuration is unrelated to transport - transport interface parameters configured via NetAct CM directly determine how user-plane traffic is carried.
問題 #25
After a remote configuration change causes unexpected cell behavior, and the automatic fallback mechanism does not fully resolve the issue, what is the most appropriate next step for the NOC engineer?
答案：B
解題說明：
When a configuration change leads to unexpected behavior and any automatic fallback does not fully restore normal operation, the appropriate recovery action is to restore the affected network element's configuration from the most recent verified backup taken before the change was applied. This returns the element to its known-working state, addressing the immediate service impact while the root cause of the unexpected behavior from the new configuration can be investigated separately, outside of the live production environment if needed. This is precisely why taking and verifying a pre-change backup is emphasized as a best practice - it provides exactly this kind of recovery option. Decommissioning the cell is a drastic and disproportionate response to a configuration issue; applying an unrelated template introduces further uncertainty and risk; and taking no action prolongs any service degradation unnecessarily, which is inconsistent with the NOC's responsibility to restore service promptly.
問題 #26
What is the key distinction between a full site backup and a partial (configuration-only) backup in the context of base station lifecycle management?
答案：C
解題說明：
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.
