Question 2

Why is it considered a best practice to verify the integrity of a configuration or software backup file shortly after it is created, rather than assuming the backup process completed successfully?

A. Because unverified backups cause the base station to continuously restart B. Because verification is required by NetAct before any alarms can be displayed for the element C. Because a backup that appears to have completed without verification could be incomplete or corrupted, and this would only be discovered when it is needed for a restore - at which point recovery options become severely limited D. Because backup verification automatically improves the cell's KPI performance

Question 3

During a remote piloting activity, the NOC engineer and field engineer are unable to bring a replaced RF unit into service despite following standard verification and troubleshooting steps, and a hardware fault on the new unit itself is suspected. What is the most appropriate next step?

A. Permanently delete the cell's configuration from NetAct to resolve the issue B. Instruct the field engineer to discard the new unit and leave the site without further communication C. Escalate the issue to the next-level support team or vendor technical assistance, providing documented details of the steps already performed, the symptoms observed, and the suspected hardware fault, to support further diagnosis or part replacement D. Continue indefinitely repeating the same remote troubleshooting steps without involving any other teams

Question 7

During remote piloting of a RET replacement, the field engineer reports that the new RET unit is physically connected, but the NOC engineer cannot detect it during an AISG device scan, while other ALDs on the same antenna line are detected normally. What is a likely cause the NOC engineer should consider?

A. The new RET unit may have an AISG address conflict with another device on the same bus, or the connection to the bus itself may be faulty B. The cell's NR-ARFCN is configured incorrectly C. The site's Tracking Area Code needs to be updated to match the new device D. The RET unit's tilt range is set too high
