88. Frage
A NOC engineer needs to recover a base station from a state where its parameter settings have been corrupted, but the underlying software load is functioning correctly. Which type of backup would be most directly applicable to resolving this specific issue?
Antwort: B
Begründung:
When the issue is specifically that parameter/configuration data has become corrupted while the underlying software load remains functional, the most directly applicable recovery resource is a configuration backup - which contains the parameter settings (cell configuration, neighbor relations, transport settings, and so on) independent of the software image. Restoring from a configuration backup can address the corrupted settings without the additional time and disruption of reinstalling or reactivating software, which would be unnecessary in this scenario since the software itself is not the problem. Configuration data is a distinct dataset from the software image, not embedded within it, which is precisely why configuration-only backups exist as a lighter-weight option for scenarios like this. Alarm history and PM counter exports are records of operational events and measurements respectively - neither contains the parameter configuration data needed to restore an element's settings, making them unsuitable for this recovery scenario.
89. Frage
A remote 5G site has redundant transport paths (primary and backup) providing OandM connectivity to NetAct. What is the main operational benefit of this redundancy?
Antwort: B
Begründung:
Providing dual or redundant transport paths for O and M connectivity increases the resilience of remote management. If the primary backhaul link fails - for example, due to a fiber cut or a microwave link outage - the base station can continue to report alarms and performance data, and remain reachable for configuration changes via the secondary path, preserving the Operations Center's visibility and control without requiring a site visit purely to restore management connectivity. This redundancy specifically benefits the continuity of monitoring and management functions. It has no effect on a cell's radio coverage area, which depends on RF design parameters such as transmit power, antenna configuration, and frequency band, nor does it relate to spectrum-sharing arrangements between operators. It also does not eliminate the ongoing need for periodic software updates and patching, which remain a separate lifecycle management activity.
90. Frage
A base station has the necessary software installed to support a new advanced scheduling feature, but the feature remains inactive. The NOC engineer is informed that a license-related step is required. What is the most likely explanation?
Antwort: C
Begründung:
In many telecom equipment vendors' licensing models, including Nokia's, having the software capability to support a feature installed on the base station is necessary but not always sufficient for that feature to be operational. Many advanced or optional features require a corresponding license key to be applied and activated, which represents the commercial entitlement to use that capability. This separation allows operators to purchase and activate features incrementally as needed, without requiring different software builds for different feature sets. A NOC engineer encountering an inactive feature with the correct software already installed should verify the license status for that feature and, if needed, coordinate with the appropriate team to apply or activate the required license. This is unrelated to software downgrades, hardware replacement, or waiting for a future software upgrade - none of which would resolve a licensing gap, since the underlying software already supports the feature.
91. Frage
A transport alarm 'Ethernet link down' is raised on the BTS-side interface toward the aggregation router. What is an appropriate FIRST remote action for the NOC engineer?
Antwort: D
Begründung:
When a transport-side alarm such as 'Ethernet link down' is raised on the BTS-facing interface toward the aggregation router, the appropriate first remote action is to investigate the physical and data-link layer status of that interface - checking link/port status, interface configuration such as speed and duplex settings and VLAN membership, and any visible cable/connector status indicators through management tools. If the issue appears to originate on the transport provider's side of the connection (such as a leased line or microwave link fault), coordinating with that provider is the next step. Only if remote checks cannot resolve the issue, or clearly indicate a physical hardware or cabling fault at the site, would on-site dispatch be considered.
Replacing the RF module addresses radio hardware, not a transport link fault, and modifying neighbor relations or cell bandwidth are RAN configuration changes that would not resolve a physical link failure.
92. Frage
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?
Antwort: B
Begründung:
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.
