Nokia 5G RAN Network Operations Expert Sample Questions:

Question 1

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


Question 2

Handover Success Rate is a KPI primarily used to assess which aspect of network performance?

A. Mobility performance - how successfully UEs transfer between cells
B. NetAct software license utilization
C. Software version compliance across the network
D. The integrity of configuration backup files


Question 3

Over a period of several weeks, a NOC team observes that a particular cell's average PRB utilization during the busy hour has steadily increased from 60% to consistently above 85%, even though no faults or configuration issues have been identified. What is the most appropriate action based on this trend?

A. Flag the cell for capacity planning review, as the trend suggests the cell may require additional capacity to maintain performance
B. Immediately lock the cell to prevent further load increase
C. Ignore the trend since no active alarms are present
D. Reduce the cell's transmit power to discourage new connections


Question 4

Before performing a remote software upgrade on a base station, what should a NOC engineer ensure has been completed regarding the site's current state?

A. All neighbor relations for the site have been removed to prevent interference during the upgrade
B. A current configuration and software backup has been taken and verified, providing a restore point if the upgrade encounters issues
C. All historical alarms for the site have been permanently deleted from NetAct
D. The site's PLMN ID has been changed to a temporary value during the upgrade


Question 5

A field engineer needs to work in close proximity to an antenna to replace a Tower Mounted Amplifier (TMA). What is the NOC engineer's most important responsibility before the field engineer begins this work?

A. Ensure the affected cell's RF transmission is placed into a safe state (such as locking the cell) to help protect the field engineer from RF exposure while working near the antenna
B. Disable all alarm notifications for the site for the remainder of the day
C. Increase the cell's transmit power so the field engineer can verify signal strength during the work
D. Schedule the work for the busiest traffic hour to gather more performance data during the activity
