Nokia 5G RAN Network Operations Expert Sample Questions:

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

2. For security segmentation, NOC personnel typically do not connect directly from their workstations to production AirScale base stations. Instead, they first authenticate to an intermediate, hardened host. What is this intermediate host commonly called?

A) Jump server / bastion host
B) Edge router
C) Load balancer
D) DNS server

3. Following completion of a hardware replacement and remote piloting activity, which combination of checks represents the most complete final verification before the NOC engineer closes out the activity as successful?

A) Confirming the field engineer has packed up their tools
B) Confirming the weather conditions at the site were favorable during the activity
C) Confirming the replacement part's serial number matches the shipping manifest, with no further checks required
D) Confirming all previously raised alarms related to the activity have cleared (or only expected residual alarms remain), the cell is unlocked and in service, relevant links (such as CPRI/eCPRI and AISG) report normal status, and short-term KPIs are consistent with the site's historical baseline

4. 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 requires a software downgrade before it can be used
B) 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
C) The feature can only be activated by physically replacing the baseband module
D) The feature will activate automatically once the next scheduled software upgrade occurs, regardless of licensing

5. Before applying a significant parameter change to a live production cell, what best practice should a NOC engineer follow regarding the cell's current configuration?

A) Disable all alarm reporting for the cell so that any issues caused by the change do not generate alarms
B) Delete the cell's existing configuration entirely before applying the new parameters
C) Take and securely store a configuration backup or snapshot of the current settings before applying the change, enabling rollback if the change causes unexpected issues
D) No precaution is necessary since all configuration changes in NetAct are automatically reversible without any preparation
