NEW QUESTION # 69
What best describes the role of 'remote piloting' as performed by a NOC engineer supporting a field engineer during an on-site hardware replacement?
Answer: D
Explanation:
Remote piloting describes a collaborative working model in which a NOC engineer, using centralized O and M tools such as NetAct and element managers, actively supports a field engineer performing physical work at a site. The NOC engineer's responsibilities typically include preparing the network element for the activity (such as locking affected cells), providing real-time guidance based on system status and diagnostic data, performing remote verification steps (such as confirming a replaced module is detected and operating correctly), and executing any remote configuration steps the new hardware requires. This combination of remote expertise and on-site physical capability allows complex maintenance to be carried out efficiently without requiring every engineer involved to have both deep RAN engineering and bring physically present. It is an active, collaborative role - not a passive one - and it relates only to the technical task at hand, not to logistics such as travel arrangements.
NEW QUESTION # 70
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?
Answer: D
Explanation:
When standard remote troubleshooting and on-site verification steps have been exhausted and a hardware fault on the newly installed unit itself is suspected, continuing to repeat the same steps is unlikely to be productive and delays resolution. The appropriate next step is to escalate the issue to the next level of support
- which may be a specialized technical support team or the equipment vendor's technical assistance center - providing clear documentation of what steps have already been performed, the specific symptoms observed (such as particular alarm codes or link status indications), and the basis for suspecting a hardware fault on the new unit. This documentation allows the receiving team to avoid repeating already-completed steps and to focus on deeper diagnosis, which may lead to confirming a defective unit and arranging a further replacement. Leaving the site without resolution or communication abandons the activity in an incomplete state, and deleting the cell's configuration would not address a suspected hardware defect and would create additional, unnecessary recovery work.
NEW QUESTION # 71
A field engineer needs to work in close proximity to an antenna to replace a Tower Mounted Amplifier (TMA). What is the NOC engineer's most important responsibility before the field engineer begins this work?
Answer: A
Explanation:
When a field engineer needs to work in close physical proximity to an antenna - such as when replacing a Tower Mounted Amplifier - radio frequency (RF) exposure becomes a safety consideration, since active transmission from the antenna could expose the engineer to RF energy levels exceeding safe limits at close range. The NOC engineer's most important responsibility in this scenario is to coordinate placing the affected cell's RF transmission into a safe state - typically by locking the cell - before the field engineer begins work near the antenna, and to confirm this state is in place before giving the go-ahead. This directly supports the field engineer's physical safety. Increasing transmit power would worsen RF exposure risk and is the opposite of the correct action; scheduling for busy hours is irrelevant to the safety requirement and would also affect more subscribers; and disabling alarm notifications would reduce the NOC's situational awareness during the activity without providing any safety benefit.
NEW QUESTION # 72
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?
Answer: C
Explanation:
When other Antenna Line Devices on the same AISG bus are detected normally but a newly connected device is not, two likely causes should be considered. First, AISG devices are addressed individually on the shared bus, and if the new RET unit has a factory-default or previously configured address that conflicts with an address already in use by another device on the same line, it may fail to respond correctly during discovery due to this addressing conflict. Second, despite being reported as 'physically connected,' there may be a faulty or incomplete connection specific to that device's bus connection point - such as a loose connector at the device itself - that does not affect the other devices already established on the line. The NOC engineer should work with the field engineer to check for addressing conflicts (potentially requiring the new device's address to be changed) and to verify its specific bus connection. RET tilt range, NR-ARFCN, and Tracking Area Code have no relevance to AISG device discovery issues.
NEW QUESTION # 73
In NetAct Performance Management, what is the standard default Result Output Period (ROP) used for collecting and reporting most cell-level performance measurement counters?
Answer: C
Explanation:
The default Result Output Period (ROP) for performance management counters in Nokia's RAN solution is 15 minutes. This interval provides a practical balance between granularity and system load: it is short enough to allow NOC engineers to detect emerging issues, congestion trends, and KPI fluctuations close to real time, while not generating an unmanageable volume of measurement data that would overwhelm storage and processing resources in NetAct. Fifteen-minute granularity is widely used as the basis for accessibility, retainability, mobility, integrity, and availability KPI formulas, and is the standard interval referenced in performance dashboards and automated reports. While other reporting intervals (such as 1 hour or 24 hours) can be configured for specific measurement jobs or long-term trend analysis, the 15-minute ROP remains the operational baseline for day-to-day RAN performance monitoring and troubleshooting activities performed by remote operations teams.
