Nokia 5G RAN Network Operations Expert Sample Questions:
1. What does an 'Antenna Line Device (ALD) fault' alarm on an AirScale cell typically indicate?
A) A fault affecting devices on the antenna line, such as a Remote Electrical Tilt (RET) controller or Tower-Mounted Amplifier (TMA)
B) A fault originating in the core network
C) An issue with a software feature license
D) A fault within the NetAct database server
2. What is the key difference between a graceful restart and an immediate (forced) restart of a base station unit during maintenance activities?
A) A graceful restart can only be performed by physically power-cycling the equipment on site
B) A graceful restart permanently disables the unit, while an immediate restart only temporarily disables it
C) A graceful restart attempts to allow active sessions to complete or be handed over before the restart proceeds, reducing dropped connections, while an immediate restart proceeds without waiting, causing any active sessions to be dropped
D) There is no functional difference between the two; both terms describe identical behavior
3. During a complex remote piloting activity involving multiple steps and risk of service impact, what additional coordination practice helps ensure accountability and a clear record of what was agreed and performed at each stage?
A) Conducting the activity exclusively through anonymous communication channels with no record of who performed each action
B) Performing all steps simultaneously without any sequencing to save time
C) Avoiding any real-time communication so as not to distract the field engineer
D) Conducting the activity using a shared bridge call or chat channel where each step, confirmation, and result is verbally or textually logged in real time as the activity progresses
4. 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) Accessibility - because packet loss prevents UEs from camping on the cell
B) Availability - because packet loss determines whether a cell is counted as in service
C) Integrity - because packet loss directly affects the quality and reliability of data delivered during an active session
D) Mobility - because packet loss is the main cause of handover failures
5. What is a 'threshold crossing alert' (TCA), and how does it differ from a standard equipment fault alarm?
A) It is generated when a monitored performance counter or KPI (e.g., PRB utilization) crosses a configured threshold, indicating a performance condition rather than necessarily a hardware failure
B) It is functionally identical to an equipment fault alarm in every respect
C) It applies only to software license expiry alarms
D) It is a fixed system value that operators cannot configure
