質問 # 21
When planning the channel bandwidth and subcarrier spacing for a 5G cell, what is the primary operational impact of these parameters?
正解：A
解説：
Channel bandwidth and subcarrier spacing are fundamental radio configuration parameters that together determine how many Physical Resource Blocks (PRBs) are available within a cell's carrier. Since PRBs are the basic units of radio resource that the scheduler allocates to UEs for both downlink and uplink transmissions, the number of available PRBs directly determines the cell's theoretical capacity - that is, how much traffic the cell can serve simultaneously before becoming congested. A wider channel bandwidth provides more PRBs and therefore greater capacity, while subcarrier spacing affects the size of each PRB in the frequency domain and has implications for latency and mobility performance at different frequency ranges. These parameters are foundational to capacity planning and must be configured consistently with the operator's spectrum holdings and regulatory allocations. They have no bearing on PLMN/TAC identifiers, alarm severity configuration, or O and M transport security, which are governed by entirely separate configuration domains.

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?
正解：B
解説：
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.
質問 # 23
A NOC engineer increases the configuredMaxTxPower parameter for a 5G cell as part of a coverage improvement initiative. What is the most likely operational consequence of this change?
正解：C
解説：
The configuredMaxTxPower parameter sets the maximum transmit power level the cell is permitted to use for its downlink transmissions, including reference signals and traffic channels. Increasing this value generally allows the cell's signal to reach further and penetrate obstacles more effectively, potentially expanding the effective coverage area and improving signal quality for UEs at the cell edge. However, because radio signals do not respect cell boundaries, a higher transmit power also means the cell's signal will be stronger when received by UEs and sensors in neighboring cell areas, which can increase co-channel or adjacent-channel interference - particularly relevant in dense deployments where cells are closely spaced. This trade-off means power changes should be planned carefully and their impact monitored through KPIs such as SINR and throughput in both the target cell and its neighbors. The parameter has no direct effect on software version, bandwidth configuration, or neighbor relation status, which are governed independently.
質問 # 24
After a field engineer replaces an RF unit, the NOC engineer observes that the eCPRI link between the baseband and the new RF unit remains down, even after the cell is unlocked. What should the NOC engineer do first?
正解：D
解説：
When an eCPRI (or CPRI) link remains down immediately following a physical hardware replacement, the most probable and easily verified cause is a physical-layer issue introduced during the replacement itself - such as a fiber connector not being fully seated, an SFP transceiver not properly inserted, a mismatched or faulty SFP module, or an incorrect port connection. Since the field engineer is already on site with direct physical access, the most efficient first step is to ask them to verify these physical connections before the NOC engineer invests time in deeper remote diagnostics, which would be premature given how common and simple physical connection issues are immediately after hardware work. Ordering a new baseband module is a significant escalation that should only follow ruling out simpler causes; locking the cell and closing the ticket would leave the site non-functional; and PLMN ID has no relationship to eCPRI link establishment, which operates at a lower layer entirely unrelated to network identity broadcasting.
質問 # 25
A specific neighbor relation between Cell A and Cell B shows a consistently low handover success rate, while overall network-wide mobility KPIs remain healthy. What is the most appropriate first troubleshooting step?
正解：C
解説：
Because the issue is isolated to a single neighbor relation rather than affecting overall network mobility, the problem is most likely localized to the configuration between these two specific cells rather than a broader hardware, transport, or core network fault - which would typically affect multiple relations or KPIs more broadly. The appropriate first step is to review the neighbor relation configuration, including parameters such as handover thresholds, measurement gap settings, frequency relations, and Automatic Neighbor Relation (ANR) data, to confirm the relation is correctly defined and that measurement configurations align with actual RF conditions between the two cells. Misconfigured handover thresholds, missing or incorrect frequency information, or an outdated neighbor list entry are common causes of localized handover failures.
Restarting hardware, rebooting core elements, or adjusting power network-wide are disproportionate actions that risk impacting unrelated cells and do not target the specific, isolated nature of the reported problem.
