NEW QUESTION # 97
Which statement correctly distinguishes 'Integrity' KPIs from 'Accessibility' KPIs in RAN performance management?
Answer: B
Explanation:
Accessibility KPIs measure how successfully a UE can initially establish a connection or session when it attempts to do so - for example, RRC Connection Setup Success Rate. Integrity KPIs, by contrast, measure the quality and performance of a connection once it has been successfully established - for example, achievable throughput, latency, or error rates during an active session. These represent two distinct stages of user experience: first, can the user connect at all (Accessibility), and second, once connected, how good is the service (Integrity)? They are not the same category measured differently, since they address fundamentally different performance aspects and often require different troubleshooting approaches - accessibility issues often relate to admission and signaling procedures, while integrity issues often relate to radio conditions, interference, or capacity affecting data transfer. Integrity KPIs apply across all radio generations including
5G, and Accessibility is not limited solely to throughput.
NEW QUESTION # 98
How does applying a software patch typically differ from performing a full software upgrade on a base station?
Answer: C
Explanation:
A software patch is typically a smaller, targeted update designed to address specific known issues, bugs, or vulnerabilities within the currently running software baseline, without changing the overall feature set or version baseline significantly. Patches are often quicker to apply and may have a more limited scope of impact, making them suitable for addressing urgent issues between major release cycles. A full software upgrade, by contrast, replaces the base station's overall software load with a new baseline release, which may introduce new features, performance improvements, and an accumulated set of fixes - representing a more significant change that typically requires more thorough planning, testing, and a more comprehensive pre-change backup. Both patches and full upgrades can generally be delivered and activated remotely without requiring physical hardware replacement. Understanding this distinction helps NOC teams appropriately scope the risk, testing, and scheduling considerations for each type of software lifecycle activity.
NEW QUESTION # 99
A KPI tracks the percentage of established connections or sessions that end abnormally ('dropped') rather than through a normal release procedure. Which KPI category does this belong to?
Answer: C
Explanation:
Retainability KPIs measure whether connections or sessions that have been successfully established remain stable and are terminated through normal procedures, rather than ending abnormally (a 'drop'). A high abnormal release/drop rate indicates retainability problems - subscribers may experience calls or data sessions ending unexpectedly mid-use, significantly impacting user experience even when the initial connection (accessibility) succeeded. This differs from Accessibility, which measures the success of the initial connection attempt; Mobility, which specifically measures handover performance; and Availability, which measures whether a cell or site is in service over time. Retainability degradation can result from radio link failures, interference, transport instability, or hardware issues affecting an already-active connection. NOC engineers monitoring retainability KPIs focus on the stability of in-progress sessions, a key contributor to overall subscriber-perceived quality of service.
NEW QUESTION # 100
How is the Cell Availability KPI typically calculated for a reporting period, and what does this KPI primarily reflect?
Answer: D
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.
NEW QUESTION # 101
Within NetAct, which functional module is primarily responsible for planning, distributing, and activating software packages across base stations?
Answer: A
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.
