NEW QUESTION # 26
In NetAct Performance Management, what is a 'measurement job'?
Answer: D
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 # 27
After completing a software upgrade and subsequent configuration adjustments at a site, why is it important for the NOC engineer to update the site's maintenance records and change documentation?
Answer: B
Explanation:
Maintaining accurate and current maintenance records and change documentation - detailing what changes were made, when they were performed, by whom, and the reasoning or ticket reference behind them - provides essential context for future operations. If an issue arises at the site days, weeks, or months later, having a clear record of recent changes allows engineers investigating the new issue to quickly identify whether it might be related to a recent software upgrade or configuration adjustment, significantly speeding up root-cause analysis. This documentation also supports configuration audits, compliance requirements, and knowledge transfer between team members or shifts, ensuring continuity even as different engineers interact with the site over time. While documentation does have value for regulatory and audit purposes, dismissing it as having no operational value is incorrect - it directly supports troubleshooting efficiency. Documentation itself does not trigger software downloads or determine technical parameters like PCI, which are governed by separate configuration and software lifecycle processes.
NEW QUESTION # 28
Why do NOC teams typically schedule software activation activities - which require a base station restart - for late-night or off-peak hours rather than during the day?
Answer: B
Explanation:
Activating new software on a base station typically requires the affected unit (or units) to restart, which causes a brief interruption to service for any UEs connected through that cell during the restart. To minimize the impact of this unavoidable interruption, NOC teams schedule such activities during maintenance windows that coincide with periods of lowest network traffic - commonly late at night or in the early morning hours - when the fewest subscribers are likely to be actively using the network. This reduces the number of dropped sessions and the overall visibility of the brief outage to end users. There is no technical restriction preventing restarts during daylight hours, nor does activation duration meaningfully change based on time of day, and NetAct does not impose a blanket restriction on when configuration changes can be submitted - the scheduling decision is an operational best practice driven by minimizing customer impact, not a technical limitation.
NEW QUESTION # 29
A NOC engineer notices that a cell's PRB (Physical Resource Block) utilization is consistently above 90% during peak hours. What does this MOST LIKELY indicate?
Answer: A
Explanation:
PRB (Physical Resource Block) utilization represents the proportion of a cell's available radio resources that are actively being used to carry traffic at a given time. Consistently high PRB utilization (for example, above
90%) during peak hours indicates the cell is approaching, or already experiencing, capacity congestion - there is little to no spare radio capacity to allocate to new or existing users during busy periods. This can directly affect throughput-related (Integrity) KPIs, since users may receive fewer resources than under lighter load, and can also impact accessibility if the cell becomes unable to admit new connections. This condition does not indicate a hardware failure - the cell is clearly operating and carrying significant traffic - is unrelated to PCI configuration, which is an identification parameter rather than a capacity indicator, and has no relationship to NetAct database storage. High PRB utilization is a capacity signal that may prompt load balancing, optimization, or capacity expansion actions.
NEW QUESTION # 30
Before issuing any remote commands during a piloting session that will affect a specific cell at a multi-sector site, what verification is critical for the NOC engineer to perform to avoid unintended impact?
Answer: B
Explanation:
At multi-sector sites, or in environments where many similarly named cells exist across a large network, there is a meaningful risk that a NOC engineer could inadvertently issue a remote command - such as locking a cell, adjusting a parameter, or initiating a reset - against the wrong sector or even the wrong site if identifiers are not carefully verified. Before taking any action that affects a specific cell during a piloting session, the NOC engineer should explicitly confirm with the field engineer (and against system records) that the site, sector, and cell identifiers being acted upon correspond exactly to the physical location and equipment the field engineer is working on. This verification step is a critical safeguard against unintended service impact to unrelated cells or sites, which could create a second, unrelated outage on top of the planned activity. The remaining options are entirely unrelated to technical verification and have no bearing on safely executing remote piloting commands.
