Nokia 5G RAN Network Operations Expert Sample Questions:
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 removes the ongoing need for software updates
- B. It allows two mobile operators to share the same spectrum band
- C. It doubles the radio coverage area of the cell
- D. It allows continued remote management, alarm reporting, and visibility from the Operations Center if the primary transport path fails

During a Site Acceptance Test (SAT) for a newly commissioned 5G site, what is the NOC team's typical role?
- A. To install the physical RF cabling between the antenna and the baseband unit
- B. To negotiate the commercial contract terms for the site's construction
- C. To physically inspect the antenna mounting hardware for structural compliance
- D. To remotely verify that the site is visible and manageable from centralized OandM systems, that cells come into service correctly, that no unexpected alarms are present, and that initial performance indicators are within expected ranges

After a remote configuration change causes unexpected cell behavior, and the automatic fallback mechanism does not fully resolve the issue, what is the most appropriate next step for the NOC engineer?
- A. Permanently decommission the affected cell
- B. Apply a completely different, unrelated configuration template to the cell
- C. Restore the affected network element's configuration from the most recent verified pre-change backup
- D. Wait indefinitely without taking action, since the issue will eventually self-correct
Correct Answer: C 🗳️
Explanation: Only visible for PrepAway members. You can sign-up / login (it's free).
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 NetAct only permits configuration changes to be submitted during off-peak hours
- B. Because base stations are physically unable to restart during daylight hours
- C. Because restarting the base station briefly interrupts service, and scheduling this during periods of lowest traffic minimizes the number of subscribers affected
- D. Because activation always takes significantly longer to complete at night than during the day
Correct Answer: C 🗳️

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 field engineer used a different brand of cable ties than specified
- B. The cell's PLMN ID was automatically changed during the replacement
- C. The replacement RF unit's exterior paint color does not match the original
- D. 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
