Nokia 5G RAN Network Operations Expert Sample Questions:

Question #1
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 has the same weight as the unit it replaced
B. Verify that the TMA's external housing matches the color of the antenna
C. Verify that the cell's PLMN ID has changed to reflect the new TMA
D. 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

Question #2
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

Question #3
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. Possible transport link instability, loss of synchronization reference, or unexpected hardware resets affecting the cell during those periods
B. The operator's billing system
C. NetAct user interface display/theme settings
D. The make and model of subscriber handsets in the area

Question #4
What is the primary function of the AirScale System Module within an AirScale Base Transceiver Station (BTS)?

A. Baseband processing, control-plane functions, and OandM connectivity, supporting multiple radio technologies under Single RAN
B. RF amplification and antenna interfacing
C. Providing power supply for the macro cabinet only
D. Generating the GPS satellite timing signal

Question #5
Before activating a newly downloaded software package on a base station, why is it important to verify software compatibility with the unit's current hardware and configuration?

A. Because software compatibility checks are only relevant for 2G equipment and do not apply to 5G base stations
B. Because activating an incompatible software package can result in activation failure, degraded functionality, or the unit failing to return to normal operation, even if the automatic fallback eventually recovers it
C. Because compatibility checks automatically update the site's physical inventory records
D. Because compatibility verification eliminates the need for any post-activation monitoring
