질문 # 52
A field team is planning a site visit to investigate a persistent coverage issue and requests information from the NOC to help prepare. What information can the NOC engineer most usefully provide to support this site survey?
정답：D
설명：
When a field team is preparing to investigate a persistent coverage issue, remotely available operational data can significantly improve the efficiency and focus of their site visit. The NOC engineer can provide the current configuration of the affected cell (including parameters such as transmit power, tilt settings, and azimuth where available), a review of recent alarm history to identify any recurring or unresolved fault indications, and relevant performance data such as RSRP/SINR distributions and throughput trends, which can help characterize the nature of the coverage issue (for example, distinguishing a coverage gap from an interference problem) before the field team arrives. This context allows the field team to prioritize their investigation - for example, focusing on antenna alignment if tilt/azimuth data looks unusual, or focusing on potential external interference sources if SINR is poor despite adequate RSRP. Subscriber personal information, equipment purchase records, and data about unrelated sites would not provide relevant technical context for this investigation.
질문 # 53
When planning the channel bandwidth and subcarrier spacing for a 5G cell, what is the primary operational impact of these parameters?
정답：C
설명：
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.
질문 # 54
Over a period of several weeks, a NOC team observes that a particular cell's average PRB utilization during the busy hour has steadily increased from 60% to consistently above 85%, even though no faults or configuration issues have been identified. What is the most appropriate action based on this trend?
정답：B
설명：
A steady upward trend in busy-hour PRB utilization over multiple weeks, in the absence of faults or configuration changes, is a classic indicator of organic traffic growth gradually consuming available capacity. While the cell may still be performing acceptably at 85% utilization, continuing this trend risks crossing into the congestion range (typically above 90%) where accessibility and throughput KPIs begin to degrade. The appropriate response is proactive: flagging the cell for capacity planning review allows engineers to evaluate options such as adding carriers, adjusting load balancing parameters, or planning sectorization before performance actually suffers. Ignoring the trend risks a reactive, customer-impacting outcome once congestion thresholds are crossed. Locking the cell or reducing transmit power would actively degrade service for existing users and is not an appropriate response to a capacity trend - these actions would be counterproductive and harm the very users the network is meant to serve.
질문 # 55
After successfully completing a significant remote configuration change on a base station and confirming normal operation, what additional lifecycle management step should the NOC team perform?
정답：B
설명：
Once a significant configuration change has been successfully applied and verified - meaning the network element is operating normally with the new configuration in place - it is good practice to take an updated backup reflecting this new state. This becomes the new baseline restore point for any future changes, ensuring that if a subsequent change needs to be rolled back, the rollback target reflects the current, correct configuration rather than an outdated one that no longer matches the network element's intended state.
Restoring the previous backup immediately after a successful change would simply undo the work just completed, which is counterproductive. Deleting backups removes valuable recovery options and is contrary to good change management practice. Disabling the element's connection to NetAct would prevent the NOC from performing any future monitoring, fault management, or configuration activities on that element, which is operationally undesirable and unrelated to good post-change practice.
질문 # 56
After a field engineer replaces a Tower Mounted Amplifier (TMA), what remote check should the NOC engineer perform to confirm the new TMA is correctly configured and operating within expected parameters?
정답：D
설명：
A Tower Mounted Amplifier (TMA) is an Antenna Line Device that, like a RET unit, communicates over the AISG bus and has configurable operational parameters - notably its gain settings (which affect uplink signal amplification) and bias/power settings. After a TMA replacement, the appropriate remote verification is to confirm the new unit is detected on the AISG bus (confirming physical and communication-layer connectivity) and that its gain and bias settings can be read and correspond to the values expected for that antenna line's configuration, ensuring the device is operating within the parameters the radio link design assumes. Incorrect TMA gain settings can affect uplink sensitivity and noise figure, impacting uplink performance KPIs. Physical attributes such as housing color or weight have no bearing on functional verification, and TMA replacement has no relationship to the cell's PLMN ID, which is a network identity parameter entirely independent of antenna line equipment.
