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

2. After a field engineer installs a brand-new RET unit (not a like-for-like replacement, but a new addition to the antenna line) and connects it to the AISG bus, what initial remote action does the NOC engineer typically need to perform to bring the device under management?

A) Perform an AISG device scan/discovery to detect the new device on the bus and then configure it within the system so it can be monitored and controlled
B) Change the cell's Tracking Area Code to match the RET unit's serial number
C) Manually rewrite the base station's entire software image
D) Physically relocate the baseband unit to a different rack position

3. Before issuing any remote commands during a piloting session that will affect a specific cell at a multi-sector site, what verification is critical for the NOC engineer to perform to avoid unintended impact?

A) Confirm the total number of years the field engineer has worked for their company
B) Confirm the correct site, sector, and cell identifiers match the specific cell the field engineer is physically working on, ensuring remote commands are not inadvertently applied to a different sector or an unrelated site
C) Confirm the field engineer's preferred lunch order for the day
D) Confirm the color of the field engineer's safety vest

4. A NOC engineer needs to recover a base station from a state where its parameter settings have been corrupted, but the underlying software load is functioning correctly. Which type of backup would be most directly applicable to resolving this specific issue?

A) A PM counter export, since it records the configuration state at each reporting interval
B) A configuration backup, since it contains the parameter data needed to restore the element's settings without requiring a software reinstallation
C) An alarm history export, since it contains the parameter values needed for restoration
D) A software backup only, since configuration data is always embedded within the software image itself

5. A NOC engineer needs to open an interactive command-line session directly to an AirScale BTS for advanced diagnostics. Which protocol should be used to comply with Nokia's secure remote access guidelines?

A) HTTP
B) SSH
C) SNMPv1
