Within NetAct, which functional module is primarily responsible for planning, distributing, and activating software packages across base stations?
Answer: C
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.

What is the primary purpose of the Tracking Area Code (TAC) configured on a 5G cell?
Answer: B
Explanation:
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.
NEW QUESTION # 82
In NetAct Performance Management, what is a 'measurement job'?
Answer: B
Explanation:
In NetAct Performance Management, a 'measurement job' is a configured task that specifies which performance counters or KPIs should be collected, from which network elements (such as specific base stations or cells), and at what collection interval - for example, every 15 minutes or hourly. These jobs are the mechanism by which raw counter data is gathered from the RAN and made available for KPI calculation, reporting dashboards, and threshold-based alerting. Without properly configured measurement jobs covering the relevant counters and elements, the performance data needed to assess network health and detect KPI degradation would simply not be collected. This is distinct from a field technician's scheduled maintenance task, a software upgrade package (a Software Management concept), or a user account (an access control concept) - a measurement job specifically governs the automated, ongoing collection of performance statistics within the PM functional area.
NEW QUESTION # 83
In an EN-DC (E-UTRA New Radio Dual Connectivity) configuration, what role does the 5G NR cell typically play relative to the LTE cell?
Answer: A
Explanation:
EN-DC is a non-standalone (NSA) 5G deployment architecture in which a UE maintains simultaneous connections to an LTE eNB acting as the Master Node (MN) and a 5G NR gNB acting as a Secondary Node (SN). In this configuration, the LTE eNB anchors the control-plane connection to the Evolved Packet Core (EPC) and handles mobility management and signaling, while the NR cell primarily contributes additional user-plane throughput and capacity through dual connectivity, often substantially increasing the data rates available to the UE. This architecture allows operators to introduce 5G capacity using existing 4G core infrastructure, which is a common early-stage deployment strategy. Correct configuration of the EN-DC relation between the LTE and NR cells - including neighbor relations, frequency information, and capability signaling - is essential for the UE to be directed to add the secondary NR connection. EN-DC does not require identical PCI values between the LTE and NR layers, since they operate as distinct cells with independent identity spaces.
NEW QUESTION # 84
How is the Cell Availability KPI typically calculated for a reporting period, and what does this KPI primarily reflect?
Answer: C
Explanation:
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.
