Nokia 5G RAN Network Operations Expert Sample Questions:
A NOC engineer notices that UEs in a cell are triggering handovers to a neighboring cell and then quickly handing back, repeating this cycle (a 'ping-pong' pattern). Which parameter adjustment is most likely to help reduce this behavior?
- A. Disabling the neighbor relation between the two cells entirely
- B. Increasing the handover event hysteresis and/or time-to-trigger values for the relevant measurement event between the two cells
- C. Reducing the channel bandwidth of both cells
- D. Increasing the PCI value of one of the two cells

When configuring NR-NR (5G-to-5G) neighbor relations to support mobility between two 5G cells operating on different frequency bands, which type of neighbor relation must be established?
- A. No neighbor relation is required since inter-band handovers occur automatically without configuration
- B. An inter-frequency neighbor relation, including the appropriate frequency and measurement configuration for the target band
- C. An intra-frequency neighbor relation only
- D. An EN-DC relation, since any handover involving different frequencies requires LTE anchoring

After a field engineer replaces an RF unit, the NOC engineer observes that the eCPRI link between the baseband and the new RF unit remains down, even after the cell is unlocked. What should the NOC engineer do first?
- A. Immediately order a replacement baseband module to be shipped to the site
- B. Ask the field engineer to verify the physical fiber connections and SFP transceivers between the baseband and the new RF unit before pursuing further remote diagnosis
- C. Change the cell's PLMN ID to force the eCPRI link to re-establish
- D. Permanently lock the cell and close the maintenance ticket as complete
Correct Answer: B 🗳️

What is the key difference between a cell that has been administratively 'locked' (disabled) and a cell that reports 'Out of Service' due to a fault?
- A. 'Locked' cells always operate at higher transmit power than normal
- B. 'Locked' reflects a deliberate administrative action taken intentionally, while 'Out of Service' due to a fault reflects an unintended operational failure
- C. 'Out of Service' cells are always the result of a software upgrade in progress
- D. There is no real difference; the two terms describe the same situation

When planning a maintenance window for a software activation affecting multiple cells at a site, which factor is most important for the NOC team to consider in order to minimize subscriber impact?
- A. Historical traffic patterns for the site, choosing a time period when traffic is at its lowest to minimize the number of active sessions affected by the restart
- B. The number of active alarms at the site, since more alarms always mean lower traffic
- C. The PLMN ID of the site, since different PLMN IDs require different maintenance windows
- D. The current software version number, since higher version numbers always indicate lower traffic
