A cell consistently shows PRB utilization above 90% during peak hours, along with a rising number of RRC Connection Rejections due to insufficient resources. What does this combination of indicators most strongly suggest?

• A. The cell is experiencing a hardware fault on the RF unit
• B. The cell is suffering from capacity congestion during peak traffic periods
• C. The cell's GNSS synchronization reference has been lost
• D. The cell has an incorrect neighbor relation configuration

In NetAct Performance Management, what is a 'measurement job'?

• A. A user account created specifically for performance management staff
• B. A type of software upgrade package for AirScale base stations
• C. A configured task defining which performance counters are collected, from which network elements, and at what interval
• D. A maintenance task scheduled for a field technician at a site

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. Availability - because packet loss determines whether a cell is counted as in service
• C. Mobility - because packet loss is the main cause of handover failures
• D. Accessibility - because packet loss prevents UEs from camping on the cell

After a field engineer replaces a Tower Mounted Amplifier (TMA), what remote check should the NOC engineer perform to confirm the new TMA is correctly configured and operating within expected parameters?

• A. Verify that the TMA's external housing matches the color of the antenna
• B. Verify that the TMA has the same weight as the unit it replaced
• C. Verify that the TMA is detected on the AISG bus and that its gain and bias settings are read correctly and align with the expected configuration for that antenna line
• D. Verify that the cell's PLMN ID has changed to reflect the new TMA

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 restarting the base station briefly interrupts service, and scheduling this during periods of lowest traffic minimizes the number of subscribers affected
• 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 base stations are physically unable to restart during daylight hours
