질문 # 34
In an EN-DC (E-UTRA New Radio Dual Connectivity) configuration, what role does the 5G NR cell typically play relative to the LTE cell?
정답：D
설명：
EN-DC is a non-standalone (NSA) 5G deployment architecture in which a UE maintains simultaneous connections to an LTE eNB acting as the Master Node (MN) and a 5G NR gNB acting as a Secondary Node (SN). In this configuration, the LTE eNB anchors the control-plane connection to the Evolved Packet Core (EPC) and handles mobility management and signaling, while the NR cell primarily contributes additional user-plane throughput and capacity through dual connectivity, often substantially increasing the data rates available to the UE. This architecture allows operators to introduce 5G capacity using existing 4G core infrastructure, which is a common early-stage deployment strategy. Correct configuration of the EN-DC relation between the LTE and NR cells - including neighbor relations, frequency information, and capability signaling - is essential for the UE to be directed to add the secondary NR connection. EN-DC does not require identical PCI values between the LTE and NR layers, since they operate as distinct cells with independent identity spaces.
질문 # 35
Why does NetAct support configuring automatic notifications, such as email or SMS, for Critical severity alarms to NOC personnel?
정답：C
설명：
NetAct supports configuring automatic notifications, such as email or SMS alerts, to be sent to designated NOC personnel when alarms of a certain severity - commonly Critical - are raised. This ensures severe issues are brought to the attention of responsible engineers promptly, even if no one is actively viewing the live FM dashboard at that exact moment, helping reduce the time between a fault occurring and corrective action beginning. This notification mechanism complements, rather than replaces, the FM dashboard, which remains necessary for detailed investigation, alarm correlation across the network, and ongoing monitoring of all severity levels. It does not automatically fix any underlying fault - it is purely an awareness mechanism - and has no effect on how many alarms the network actually generates, which is determined by real fault conditions and configured alarm definitions/thresholds, not by notification settings.
질문 # 36
Some alarms in NetAct FM clear automatically once the underlying fault condition no longer exists, while others require manual clearing by an engineer. What characterizes an alarm that requires manual clearing?
정답：C
설명：
Many alarms in NetAct FM are designed to self-clear: once the network element detects that the underlying condition no longer exists - for example, a transient link flap recovering on its own - the element sends a clear notification and the alarm is automatically removed from the active list. However, some alarms represent conditions where the element cannot reliably self-verify resolution, such as certain hardware faults requiring physical intervention, or conditions tied to actions needing human confirmation. These alarms may remain active even after corrective action has been taken, until an engineer manually clears them or the system completes a subsequent successful self-test. NOC engineers need to understand this distinction so the active alarm list accurately reflects current network status, and so that manual clearing is correctly performed as part of completing a maintenance action where required.
질문 # 37
A 'High VSWR' (Voltage Standing Wave Ratio) alarm is raised on an RF unit's antenna branch. What does this alarm typically indicate a problem with?
정답：D
설명：
Voltage Standing Wave Ratio (VSWR) measures how efficiently RF energy transmitted by the radio unit is delivered into the antenna system versus being reflected back due to an impedance mismatch. A High VSWR alarm indicates a significant mismatch on a particular antenna branch or port, commonly caused by issues such as a damaged or loose feeder cable connection, a faulty or improperly seated RF connector, moisture
/water ingress into a connector, or physical damage to an antenna element. This is a radio-frequency hardware issue on the affected branch and is entirely unrelated to NetAct server storage, core network mobility functions, or billing systems. For NOC engineers, a persistent High VSWR alarm typically signals that a field visit may be needed to inspect and repair the physical RF connections or replace damaged hardware on that antenna line, since it is a physical-layer condition not resolvable through remote configuration alone.
질문 # 38
A NOC engineer wants to confirm that a newly installed AirScale BTS has completed commissioning and is ready to carry live traffic. Which indicator provides this confirmation?
정답：C
설명：
Commissioning brings a newly installed AirScale BTS under NetAct management, loads the correct software and configuration, and activates its cells. The definitive operational confirmation that commissioning is complete and the site is ready for live service is that the relevant cells show an unlocked (administratively enabled) state combined with an operational 'in service'/available status in NetAct, and there are no outstanding blocking faults or critical alarms preventing service. This combination of administrative and operational state, together with a clean alarm list, is what NOC engineers check before confirming a site is live. Appearing on a mapping tool, having fiber physically installed by the transport provider, or having power equipment installed are all useful prerequisite facts about the site's physical readiness, but none of them confirm that the RAN equipment itself has successfully completed commissioning and is carrying traffic.
