NEW QUESTION # 121
Within NetAct, which functional module is primarily responsible for planning, distributing, and activating software packages across base stations?
Answer: D
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 # 122
What does an 'Antenna Line Device (ALD) fault' alarm on an AirScale cell typically indicate?
Answer: D
Explanation:
Antenna Line Devices (ALDs) include components such as Remote Electrical Tilt (RET) controllers, which allow remote adjustment of antenna downtilt, and Tower-Mounted Amplifiers (TMAs), which improve uplink sensitivity by amplifying received signals near the antenna. These devices communicate with the BTS over an AISG (Antenna Interface Standards Group) bus. An ALD fault alarm indicates a problem with one of these antenna-line components or their communication link - for example, a RET controller not responding to commands, a configuration mismatch, or a power/connectivity issue on the AISG bus. This is unrelated to the NetAct database, software licensing, or any core network issue. Recognizing this alarm correctly scopes the problem to antenna-line equipment, which may be resolvable remotely (re-querying or reconfiguring the device) or may require a field technician to inspect AISG cabling or replace the faulty ALD if remote actions fail.
NEW QUESTION # 123
An AirScale base station simultaneously raises a 'Cell Out of Service' alarm and an 'RF unit communication failure' alarm. How should a NOC engineer typically interpret this combination using alarm correlation principles?
Answer: A
Explanation:
Alarm correlation in Fault Management helps distinguish a root-cause alarm from symptom (consequent) alarms that appear together for a single underlying problem. In this scenario, an RF unit communication failure indicates a problem with the radio hardware or its link to the baseband, which directly prevents the cell served by that RF unit from operating - this generates the Cell Out of Service alarm as a direct consequence. NOC procedure is to focus remediation on the root-cause alarm (the RF unit communication failure); resolving it should automatically clear the dependent Cell Out of Service alarm. Treating both as separate, unrelated faults wastes troubleshooting effort on what is really a single underlying issue. NetAct can display many simultaneous alarms per element, and a Cell Out of Service alarm is itself a symptom, not a cause of hardware failure.
NEW QUESTION # 124
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: A
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 # 125
Which AirScale management tool allows an engineer to connect directly to a single base station for local-level configuration viewing and diagnostics, as opposed to network-wide centralized management?
Answer: B
Explanation:
The BTS Site Manager, also referred to as the local Element Manager, is the tool used to connect directly to an individual AirScale base station to view its local configuration, hardware inventory, logs, and run element- level diagnostics. It is typically used when an engineer needs granular, site-specific information that may not be fully visible through the centralized system, or when NetAct connectivity to the site is impaired. NetAct CM Editor is used for network-wide configuration management of many sites from the central OSS, NetAct PM Reports aggregates performance counters across the network, and the SON Network Optimizer automates parameter tuning across multiple cells. Because the question specifically asks about direct, single-element access for local diagnostics rather than network-wide operations, the BTS Site Manager is the correct answer, complementing NetAct in a complete remote operations toolkit.
