質問 # 49
Following completion of a hardware replacement and remote piloting activity, which combination of checks represents the most complete final verification before the NOC engineer closes out the activity as successful?
正解：B
解説：
A complete final verification after a hardware replacement and remote piloting activity should confirm multiple dimensions of the site's restored operational state. This includes checking that alarms directly related to the replaced component and the maintenance activity itself have cleared as expected (with any remaining alarms understood and unrelated to the activity), confirming the affected cell has been unlocked and successfully returned to an in-service state, verifying that relevant communication links - such as CPRI
/eCPRI links to RF units or the AISG bus connection to antenna line devices - report normal status, and reviewing short-term performance indicators to confirm they are consistent with the site's established baseline, indicating the cell is performing as expected under real traffic. Only this combination provides genuine assurance that the activity was successful end-to-end. Administrative details like tool packing, serial number matching against shipping records (while useful for inventory purposes), and weather conditions do not address whether the network element is actually functioning correctly.
質問 # 50
A site reports a 'Rectifier Fault' or 'DC Power Fault' alarm together with multiple equipment alarms across different cabinets. What does the rectifier/DC power fault alarm relate to?
正解：B
解説：
A 'Rectifier Fault' or 'DC Power Fault' alarm relates to the site's power infrastructure - specifically the rectifier units that convert incoming AC mains power into the DC voltage used by BTS equipment, often backed by a battery system to ride through short outages. When this alarm appears alongside multiple equipment alarms across different cabinets or modules at the same site, it strongly suggests a shared power supply problem affecting all equipment dependent on that source, rather than independent hardware faults occurring coincidentally across multiple unrelated components. This is unrelated to software licensing, neighbor cell configuration, or NetAct user permissions. Recognizing this pattern helps the NOC engineer correctly identify a power infrastructure issue as the likely root cause, prompting checks on AC mains status, battery backup health, or coordination with site facilities/power maintenance teams, rather than independently chasing each equipment alarm as a separate RAN hardware fault.
質問 # 51
During a remote piloting session, what communication practice is most important for the NOC engineer and field engineer to follow to ensure tasks are completed safely and correctly?
正解：B
解説：
Effective remote piloting depends on clear, step-by-step communication where each action - whether performed by the field engineer physically or the NOC engineer remotely - is confirmed as complete before the next dependent step proceeds. This sequential confirmation approach ensures that both parties maintain an accurate, shared understanding of the site's current state at every point in the procedure, which is critical for both safety (for example, confirming a cell is locked before physical work begins near an antenna) and technical correctness (for example, confirming a physical connection has been made before the NOC engineer attempts to verify it remotely). Providing all instructions upfront without ongoing confirmation risks steps being missed, performed out of order, or performed before prerequisite conditions are met. Relying solely on non-real-time communication such as email is impractical for time-sensitive coordination, and allowing the field engineer to proceed entirely independently removes the collaborative verification that makes remote piloting effective and safe.
質問 # 52
What best describes the role of 'remote piloting' as performed by a NOC engineer supporting a field engineer during an on-site hardware replacement?
正解：C
解説：
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.
質問 # 53
Before performing a remote software upgrade on a base station, what should a NOC engineer ensure has been completed regarding the site's current state?
正解：A
解説：
Taking and verifying a current configuration and software backup before a remote software upgrade is a fundamental pre-upgrade step. This backup captures the site's known-working state - including its current software load and configuration parameters - immediately before changes are introduced. If the upgrade fails, results in unexpected behavior, or the automatic fallback mechanism does not fully restore normal operation, this backup provides a verified restore point that the NOC can use to recover the site to its prior working condition, minimizing downtime and avoiding the need for a more disruptive recovery process such as a full re-commissioning. Deleting alarm history, changing the PLMN ID, or removing neighbor relations are not standard or appropriate pre-upgrade steps; they would either destroy useful troubleshooting history, disrupt subscriber service through incorrect network identification, or unnecessarily degrade mobility performance, none of which relate to safely preparing for a software upgrade.
