11. Frage
Before rolling out a new software release across an entire region's base stations, an operator first activates it on a small subset of sites and closely monitors their performance for a period of time. What is this practice commonly called, and what is its primary benefit?
Antwort: A
Begründung:
A staged or pilot rollout - sometimes referred to as a canary deployment - involves activating a new software release on a small, representative subset of sites first, then closely monitoring key indicators such as alarms, KPIs, and overall stability for a defined observation period before proceeding with wider deployment. The primary benefit of this approach is risk containment: if the new software introduces an unforeseen issue - whether a compatibility problem, a performance regression, or an unexpected interaction with certain configurations - the impact is limited to the pilot sites rather than the entire region, allowing the issue to be identified and addressed (potentially by halting further rollout) before it affects a much larger portion of the network. This practice is a software lifecycle risk-management technique and is unrelated to factory resets, configuration audits focused on PLMN consistency, or bulk parameter updates, which serve entirely different operational purposes.
12. Frage
While remotely piloting an RF unit replacement, the NOC engineer notices the new unit is detected but the cell fails to come into service, with an alarm indicating a CPRI/eCPRI configuration mismatch. What is a likely cause that the NOC and field engineer should jointly investigate?
Antwort: A
Begründung:
A CPRI/eCPRI configuration mismatch alarm following a hardware replacement often indicates that the physical connection topology does not align with what the system's configuration expects - commonly because the replacement RF unit was connected to a different physical port on the baseband module than the original unit occupied. Since configuration data often references specific port mappings to associate logical cell configurations with specific physical RF unit connections, a port mismatch can prevent the system from correctly associating the detected hardware with the expected configuration, resulting in the cell failing to come into service despite the link being physically established. The NOC engineer should work with the field engineer to confirm exactly which physical port the new unit is connected to and compare this against the expected port mapping in the configuration, correcting either the physical connection or the configuration as appropriate. Cosmetic details such as cable ties or paint color, and unrelated identifiers like PLMN ID, have no bearing on this type of technical mismatch.
13. Frage
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?
Antwort: B
Begründung:
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.
14. Frage
In the context of Nokia's Single RAN approach, what does it mean for a base station site's software package to support 'Single RAN'?
Antwort: C
Begründung:
Single RAN is an architectural approach in which a common hardware platform - such as the AirScale System Module and associated radio units - and an integrated software package can simultaneously support multiple radio access technologies (for example, 2G, 3G, 4G, and 5G) on the same shared infrastructure, rather than requiring separate, technology-dedicated equipment for each generation. This significantly reduces the physical footprint, power consumption, and operational complexity at a site, since multiple technologies can be managed, monitored, and upgraded through unified O and M tools and processes. A Single RAN site is not restricted to a single technology - in fact, the opposite is true: it is designed specifically to host multiple technologies concurrently. It also does not require separate cabinets per technology, and it remains fully capable of receiving ongoing software upgrades and lifecycle management like any other deployment, with Single RAN describing the architectural integration rather than a static, unchangeable state.
15. Frage
How is the Cell Availability KPI typically calculated for a reporting period, and what does this KPI primarily reflect?
Antwort: D
Begründung:
Cell Availability is an Availability-category KPI that measures the proportion of a given reporting period during which a cell was operationally able to carry traffic - that is, unlocked, in service, and not blocked by a fault. It is calculated as the ratio of the time the cell was actually available to the total duration of the reporting period, expressed as a percentage. Periods of planned maintenance (administrative locking) are sometimes excluded or tracked separately from unplanned outages, depending on operator reporting policy, since the two have different operational implications. This KPI is critical for service level agreement (SLA) reporting and for identifying cells with recurring stability issues such as repeated automatic resets, hardware faults, or transport outages. It is distinct from throughput-based, handover-based, or alarm-count-based ratios, which belong to other KPI categories and answer different operational questions.
