NEW QUESTION # 92
Before activating a newly downloaded software package on a base station, why is it important to verify software compatibility with the unit's current hardware and configuration?
Answer: D
Explanation:
Verifying that a software package is compatible with a base station's specific hardware variants, installed modules, and current configuration before activation helps avoid activation failures or operational issues that can arise when a software load does not properly support the hardware it is being applied to, or when configuration elements are incompatible with structural changes introduced in the new software. While an automatic fallback mechanism may eventually recover the unit to its previous working state if activation fails, relying on fallback as the primary safeguard introduces avoidable service disruption and consumes a maintenance window without achieving the intended upgrade. Compatibility considerations are relevant across all supported technologies within Nokia's Single RAN portfolio, not just legacy systems, and compatibility checks are a software lifecycle planning activity - they do not update physical inventory records or remove the need for post-activation health monitoring, which remains essential regardless of how thorough the pre-activation checks were.
NEW QUESTION # 93
Within NetAct, which functional module is primarily responsible for planning, distributing, and activating software packages across base stations?
Answer: B
Explanation:
The Software Management (SWM) module within NetAct is the centralized functional area responsible for the end-to-end software lifecycle of base stations and other network elements, including planning software deployment campaigns, distributing (downloading) software packages to target network elements, scheduling and triggering activation, and monitoring the success or failure of these operations across potentially large numbers of sites. This is distinct from Fault Management (FM), which handles alarms and fault conditions; Performance Management (PM), which handles KPI and counter-based performance data; and Configuration Management (CM), which handles parameter and configuration provisioning. While these modules may interact - for example, a software activation might generate alarms visible in FM, or a software change might necessitate subsequent configuration adjustments via CM - the core responsibility for managing software packages, versions, and activation campaigns rests specifically with SWM, making it the primary tool a NOC engineer would use for software lifecycle activities.
NEW QUESTION # 94
When configuring NR-NR (5G-to-5G) neighbor relations to support mobility between two 5G cells operating on different frequency bands, which type of neighbor relation must be established?
Answer: C
Explanation:
When two 5G NR cells operate on different frequency bands (or different carrier frequencies within the same band), mobility between them requires an inter-frequency neighbor relation to be configured. This relation must include the necessary frequency information identifying the target carrier, along with measurement configuration parameters that instruct the UE when and how to measure the candidate target frequency - since, unlike intra-frequency measurements, inter-frequency measurements typically require measurement gaps and are not performed continuously by the UE. An intra-frequency neighbor relation would only be appropriate if both cells operated on the same carrier frequency, which is not the case here. Inter-band 5G-to-
5G handovers are not automatic without configuration; the network must explicitly define the relation and measurement parameters to enable the UE to detect and report the target cell. EN-DC relations are specifically for LTE-NR dual connectivity scenarios and are unrelated to NR-NR mobility between two 5G cells.
NEW QUESTION # 95
A base station has the necessary software installed to support a new advanced scheduling feature, but the feature remains inactive. The NOC engineer is informed that a license-related step is required. What is the most likely explanation?
Answer: C
Explanation:
In many telecom equipment vendors' licensing models, including Nokia's, having the software capability to support a feature installed on the base station is necessary but not always sufficient for that feature to be operational. Many advanced or optional features require a corresponding license key to be applied and activated, which represents the commercial entitlement to use that capability. This separation allows operators to purchase and activate features incrementally as needed, without requiring different software builds for different feature sets. A NOC engineer encountering an inactive feature with the correct software already installed should verify the license status for that feature and, if needed, coordinate with the appropriate team to apply or activate the required license. This is unrelated to software downgrades, hardware replacement, or waiting for a future software upgrade - none of which would resolve a licensing gap, since the underlying software already supports the feature.
NEW QUESTION # 96
What is a 'threshold crossing alert' (TCA), and how does it differ from a standard equipment fault alarm?
Answer: C
Explanation:
A threshold crossing alert (TCA) is generated when a monitored performance counter or KPI - such as PRB utilization, processor load, or a quality metric - crosses an operator-configured threshold value, providing visibility into a performance-related condition that may or may not correspond to an actual hardware fault.
For example, sustained high PRB utilization on a cell might trigger a TCA flagging a capacity concern, prompting capacity planning or optimization actions, even though no equipment has failed. This differs fundamentally from a standard equipment fault alarm, which is raised in direct response to a detected hardware or communication failure condition. TCAs are configurable by the operator, allowing thresholds to be tuned to the network's specific performance targets and capacity planning needs, and they are not limited to software license conditions, nor are they fixed, unconfigurable values.
