Free Nokia NRN-522 Exam Dumps Questions & Answers

A NOC engineer observes an 'alarm storm' - dozens of alarms appearing within seconds across multiple cells served by the same site. What is the MOST likely explanation?

• A.  These alarms are unrelated to the site and can be safely ignored
• B.  A shared resource serving all those cells - such as the transport link, power supply, System Module, or synchronization source - has failed
• C.  Each cell independently and coincidentally developed an unrelated hardware fault at exactly the same moment
• D.  NetAct has a software defect that always duplicates alarms across cells

Before activating a newly downloaded software package on a base station, why is it important to verify software compatibility with the unit's current hardware and configuration?

• A.  Because activating an incompatible software package can result in activation failure, degraded functionality, or the unit failing to return to normal operation, even if the automatic fallback eventually recovers it
• B.  Because compatibility checks automatically update the site's physical inventory records
• C.  Because compatibility verification eliminates the need for any post-activation monitoring
• D.  Because software compatibility checks are only relevant for 2G equipment and do not apply to 5G base stations

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

After exhausting standard remote troubleshooting steps for a persistent Major alarm that remains unresolved, what is the appropriate NOC action?

• A.  Escalate the issue following defined procedures (e.g., to a higher support tier or field operations), documenting troubleshooting steps already performed
• B.  Administratively lock all cells across the entire network
• C.  Ignore the alarm and wait to see if it clears on its own
• D.  Delete the alarm record from NetAct so it no longer appears

What is the purpose of license management functionality within NetAct as it relates to base station software and features?

• A.  It tracks and manages license keys and entitlements that control which optional features and capacity levels are enabled on network elements, separate from the software installation itself
• B.  It tracks the physical inventory of spare RF cables stored at each site
• C.  It manages the PLMN IDs assigned to each base station
• D.  It schedules routine site cleaning and maintenance visits
