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?

• A.The feature can only be activated by physically replacing the baseband module
• B.The feature requires a software downgrade before it can be used
• C.The feature will activate automatically once the next scheduled software upgrade occurs, regardless of licensing
• D.Many advanced features require a valid license key to be activated in addition to having the supporting software installed, separating software capability from commercial entitlement

A NOC engineer needs to recover a base station from a state where its parameter settings have been corrupted, but the underlying software load is functioning correctly. Which type of backup would be most directly applicable to resolving this specific issue?

• A.A software backup only, since configuration data is always embedded within the software image itself
• B.A PM counter export, since it records the configuration state at each reporting interval
• C.A configuration backup, since it contains the parameter data needed to restore the element's settings without requiring a software reinstallation
• D.An alarm history export, since it contains the parameter values needed for restoration

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?

• A.Because base stations are physically unable to restart during daylight hours
• B.Because NetAct only permits configuration changes to be submitted during off-peak hours
• C.Because activation always takes significantly longer to complete at night than during the day
• D.Because restarting the base station briefly interrupts service, and scheduling this during periods of lowest traffic minimizes the number of subscribers affected

Which KPI category do uplink and downlink packet loss rate counters primarily contribute to, and why are they operationally significant for a NOC team?

• A.Integrity - because packet loss directly affects the quality and reliability of data delivered during an active session
• B.Mobility - because packet loss is the main cause of handover failures
• C.Accessibility - because packet loss prevents UEs from camping on the cell
• D.Availability - because packet loss determines whether a cell is counted as in service

A cell repeatedly raises and clears 'Cell Unavailable' alarms. Performance data shows PRB utilization dropping to zero during exactly the same periods. Which area should be investigated FIRST as the likely root cause?

• A.NetAct user interface display/theme settings
• B.The operator's billing system
• C.The make and model of subscriber handsets in the area
• D.Possible transport link instability, loss of synchronization reference, or unexpected hardware resets affecting the cell during those periods
