Nokia 5G RAN Network Operations Expert Sample Questions:

Question 1

Why does Nokia recommend configuring automatic session timeout (inactivity logout) for remote management sessions to AirScale base stations?

A. To force the base station to restart on a regular schedule
B. To increase the radio coverage range of the cell
C. To limit exposure if a session is left open and unattended, reducing the risk of unauthorized access or changes
D. To reduce electricity consumption at the site


Question 2

While remotely piloting an RF unit replacement, the NOC engineer notices the new unit is detected but the cell fails to come into service, with an alarm indicating a CPRI/eCPRI configuration mismatch. What is a likely cause that the NOC and field engineer should jointly investigate?

A. The replacement RF unit's exterior paint color does not match the original
B. The cell's PLMN ID was automatically changed during the replacement
C. The replacement RF unit is connected to a different physical port than the original unit, resulting in a mapping that does not match the existing configuration
D. The field engineer used a different brand of cable ties than specified


Question 3

After exhausting standard remote troubleshooting steps for a persistent Major alarm that remains unresolved, what is the appropriate NOC action?

A. Ignore the alarm and wait to see if it clears on its own
B. Delete the alarm record from NetAct so it no longer appears
C. Administratively lock all cells across the entire network
D. Escalate the issue following defined procedures (e.g., to a higher support tier or field operations), documenting troubleshooting steps already performed


Question 4

During remote piloting of a RET replacement, the field engineer reports that the new RET unit is physically connected, but the NOC engineer cannot detect it during an AISG device scan, while other ALDs on the same antenna line are detected normally. What is a likely cause the NOC engineer should consider?

A. The cell's NR-ARFCN is configured incorrectly
B. The RET unit's tilt range is set too high
C. The site's Tracking Area Code needs to be updated to match the new device
D. The new RET unit may have an AISG address conflict with another device on the same bus, or the connection to the bus itself may be faulty


Question 5

A remote 5G site has redundant transport paths (primary and backup) providing OandM connectivity to NetAct. What is the main operational benefit of this redundancy?

A. It doubles the radio coverage area of the cell
B. It allows two mobile operators to share the same spectrum band
C. It allows continued remote management, alarm reporting, and visibility from the Operations Center if the primary transport path fails
D. It removes the ongoing need for software updates
