104. Frage
After completing a software upgrade and subsequent configuration adjustments at a site, why is it important for the NOC engineer to update the site's maintenance records and change documentation?
Antwort: C
Begründung:
Maintaining accurate and current maintenance records and change documentation - detailing what changes were made, when they were performed, by whom, and the reasoning or ticket reference behind them - provides essential context for future operations. If an issue arises at the site days, weeks, or months later, having a clear record of recent changes allows engineers investigating the new issue to quickly identify whether it might be related to a recent software upgrade or configuration adjustment, significantly speeding up root-cause analysis. This documentation also supports configuration audits, compliance requirements, and knowledge transfer between team members or shifts, ensuring continuity even as different engineers interact with the site over time. While documentation does have value for regulatory and audit purposes, dismissing it as having no operational value is incorrect - it directly supports troubleshooting efficiency. Documentation itself does not trigger software downloads or determine technical parameters like PCI, which are governed by separate configuration and software lifecycle processes.
105. Frage
What is the primary purpose of the Tracking Area Code (TAC) configured on a 5G cell?
Antwort: C
Begründung:
The Tracking Area Code (TAC) is a configuration parameter that groups one or more cells into a Tracking Area, which the core network uses to manage UE location tracking while a device is in idle mode. When a UE moves between cells within the same Tracking Area, it does not need to perform a tracking area update, reducing signaling overhead. When a UE moves to a cell with a different TAC, it triggers a tracking area update procedure so the core network knows which area to page the UE in when there is incoming traffic.
Proper TAC planning is important: areas that are too large can increase paging load across many cells, while areas that are too small can increase signaling load from frequent tracking area updates. TAC has no relationship to hardware vendor identification, transmit power limits, or software versioning, which are configured and managed through entirely separate parameters and processes.
106. Frage
Why is an automatic fallback (rollback) mechanism important when activating new software on a base station?
Antwort: C
Begründung:
An automatic fallback mechanism is a critical safeguard in software lifecycle management. After activating a new software load, the base station undergoes a defined health-check period during which it must successfully come into normal operational state - for example, cells returning to service without critical faults. If this does not occur within the configured timeout, the automatic fallback mechanism reverts the unit to the previous software load that was known to be working, restoring service without requiring a NOC engineer to manually diagnose and correct the issue in real time. This significantly limits the duration and impact of a failed activation, which is especially important for remote sites where physical intervention would be slow. This mechanism does not delete the previous version immediately (it must remain available for the fallback to function), does not eliminate the need for post-activation monitoring, and does not automatically propagate changes to other base stations, which remains a separately scheduled and monitored activity.
107. Frage
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?
Antwort: C
Begründung:
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.
108. Frage
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?
Antwort: B
Begründung:
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.
