Nokia 5G RAN Network Operations Expert Sample Questions:
Why is it important for the NOC engineer to confirm the affected cell is locked and showing as out-of-service (in a planned state) before instructing the field engineer to disconnect any RF cabling at the antenna?
- A. Locking the cell changes the site's PLMN ID to prevent any UEs from being registered anywhere on the network
- B. Confirming the planned out-of-service state ensures the disconnection is performed on a cell that is not actively carrying traffic, supporting both safety and avoiding an unplanned service-impacting fault condition
- C. Locking the cell automatically dispatches a replacement part to the site
- D. Locking the cell increases its transmit power to assist the field engineer's measurements

An 'Equipment Over-Temperature' alarm is raised at a remote site. Besides checking the cooling system itself, what else should a NOC engineer review related to this alarm?
- A. Whether a cabinet door-open, fan failure, or HVAC/air-conditioning fault alarm is also present, indicating a broader environmental issue
- B. The cell's configured Physical Cell Identity (PCI)
- C. The handover success rate KPI
- D. The NetAct software license expiry date

Cell Availability KPI is typically calculated based on which factor?
- A. The signal strength reported by a single UE in the cell
- B. The percentage of time during a measurement period that a cell is in service, not blocked by faults or administrative locks
- C. The number of active NetAct user sessions at a given moment
- D. The total number of software upgrades performed on the cell

A KPI tracks the percentage of established connections or sessions that end abnormally ('dropped') rather than through a normal release procedure. Which KPI category does this belong to?
- A. Retainability
- B. Accessibility
- C. Mobility
- D. Availability

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