質問 # 19
A NOC engineer 'acknowledges' an active alarm in NetAct FM. What does this action signify?

A. The underlying fault has been automatically repaired
B. The alarm record is permanently deleted from the system
C. The affected base station will automatically reboot
D. The alarm has been seen and is being handled, helping avoid duplicated investigation by other team members

正解：D

解説：
Acknowledging an alarm in NetAct FM is an administrative action that marks the alarm as having been seen and taken ownership of by an engineer, without changing the underlying fault condition itself. In a NOC environment where multiple engineers or shifts monitor shared alarm lists, acknowledgement communicates that someone is already aware of and working on the issue, helping to avoid duplicated troubleshooting effort and providing a basic accountability trail for follow-up. It does not automatically resolve or repair the underlying fault - the alarm will only clear once the actual condition causing it is resolved, whether automatically by the network recovering or through engineer intervention. Acknowledgement also does not cause the base station to reboot, and acknowledged alarms remain visible in the active list (not deleted) until the underlying condition clears, at which point they typically move to the alarm history.

What is the primary purpose of the Xn interface in a 5G RAN architecture?

A. It provides direct communication between gNBs to support functions such as handover signaling and data forwarding during mobility
B. It connects the RF unit to the baseband unit within a single base station
C. It is used exclusively for software downloads from NetAct to the base station
D. It connects the gNB to the core network for user authentication only

正解：A

解説：
The Xn interface is the logical interface that connects neighboring gNBs (5G base stations) directly to one another, serving a role analogous to the X2 interface in 4G LTE. Its primary purpose is to support mobility- related signaling and data exchange between gNBs - most notably during handover procedures, where the source and target gNB use the Xn interface to coordinate the handover, exchange context information about the UE, and forward any buffered downlink user-plane data to minimize service interruption during the transition. The Xn interface can also carry information used for interference management and load balancing between neighboring cells. It is distinct from interfaces connecting the gNB to the core network (such as the NG interface), from intra-base-station interfaces like CPRI/eCPRI connecting baseband and RF units, and from the O and M connectivity used for software management, each of which serves a different architectural function within the overall RAN system.

質問 # 21
After completing a software upgrade and subsequent configuration adjustments at a site, why is it important for the NOC engineer to update the site's maintenance records and change documentation?

A. Because accurate, up-to-date records of what changes were made, when, and by whom support future troubleshooting, audits, and provide context if related issues arise later
B. Because change documentation determines the cell's PCI value
C. Because updating documentation automatically triggers a new software download to the site
D. Because documentation is purely a regulatory formality with no operational value

正解：A

解説：
Maintaining accurate and current maintenance records and change documentation - detailing what changes were made, when they were performed, by whom, and the reasoning or ticket reference behind them - provides essential context for future operations. If an issue arises at the site days, weeks, or months later, having a clear record of recent changes allows engineers investigating the new issue to quickly identify whether it might be related to a recent software upgrade or configuration adjustment, significantly speeding up root-cause analysis. This documentation also supports configuration audits, compliance requirements, and knowledge transfer between team members or shifts, ensuring continuity even as different engineers interact with the site over time. While documentation does have value for regulatory and audit purposes, dismissing it as having no operational value is incorrect - it directly supports troubleshooting efficiency. Documentation itself does not trigger software downloads or determine technical parameters like PCI, which are governed by separate configuration and software lifecycle processes.

質問 # 22
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?

A. Verify that the TMA is detected on the AISG bus and that its gain and bias settings are read correctly and align with the expected configuration for that antenna line
B. Verify that the cell's PLMN ID has changed to reflect the new TMA
C. Verify that the TMA has the same weight as the unit it replaced
D. Verify that the TMA's external housing matches the color of the antenna

正解：A

解説：
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.

質問 # 23
What is the primary purpose of the Tracking Area Code (TAC) configured on a 5G cell?

A. It defines the maximum transmit power permitted for the cell
B. It specifies which software version is installed on the base station
C. It identifies the specific hardware vendor of the baseband unit
D. It groups cells into areas used for UE location tracking and paging in idle mode, helping manage mobility signaling efficiently

正解：D

解説：
The Tracking Area Code (TAC) is a configuration parameter that groups one or more cells into a Tracking Area, which the core network uses to manage UE location tracking while a device is in idle mode. When a UE moves between cells within the same Tracking Area, it does not need to perform a tracking area update, reducing signaling overhead. When a UE moves to a cell with a different TAC, it triggers a tracking area update procedure so the core network knows which area to page the UE in when there is incoming traffic.
Proper TAC planning is important: areas that are too large can increase paging load across many cells, while areas that are too small can increase signaling load from frequent tracking area updates. TAC has no relationship to hardware vendor identification, transmit power limits, or software versioning, which are configured and managed through entirely separate parameters and processes.
