Nokia NRN-522 Exam Syllabus Topics:

Nokia 5G RAN Network Operations Expert Sample Questions:

1. A NOC engineer is considering performing a remote factory reset on a base station as a troubleshooting step for a persistent issue. What is the most significant risk of this action if performed without proper preparation?

A) A factory reset only affects the unit's physical LED indicators and has no impact on service
B) A factory reset automatically creates a new backup of the current configuration before proceeding
C) A factory reset has no effect on the unit's configuration and is therefore always safe to perform
D) A factory reset may erase the unit's current configuration, requiring a full restoration from backup (or re- commissioning) to return the site to its operational state

2. A NOC engineer wants to confirm that a newly installed AirScale BTS has completed commissioning and is ready to carry live traffic. Which indicator provides this confirmation?

A) The relevant cells show an unlocked/enabled administrative state and an operational 'in service' status in NetAct, with no blocking alarms
B) The site appears correctly on a public mapping application
C) The transport provider confirms that fiber has been physically installed at the site
D) The power equipment vendor confirms their installation is complete

3. 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

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) The feature will activate automatically once the next scheduled software upgrade occurs, regardless of licensing
C) 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
D) The feature can only be activated by physically replacing the baseband module

5. A NOC engineer increases the configuredMaxTxPower parameter for a 5G cell as part of a coverage improvement initiative. What is the most likely operational consequence of this change?

A) The change has no impact on coverage or interference, only on the cell's software version
B) The change will immediately disable all neighbor relations associated with the cell
C) The cell's coverage area may expand, but interference toward neighboring cells operating on the same or adjacent frequencies may also increase
D) The cell will automatically reduce its bandwidth to compensate for the power increase
