54. Frage
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?
Antwort: C
Begründung:
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.
55. Frage
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?
Antwort: B
Begründung:
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.
56. Frage
In the context of Nokia's Single RAN approach, what does it mean for a base station site's software package to support 'Single RAN'?
Antwort: B
Begründung:
Single RAN is an architectural approach in which a common hardware platform - such as the AirScale System Module and associated radio units - and an integrated software package can simultaneously support multiple radio access technologies (for example, 2G, 3G, 4G, and 5G) on the same shared infrastructure, rather than requiring separate, technology-dedicated equipment for each generation. This significantly reduces the physical footprint, power consumption, and operational complexity at a site, since multiple technologies can be managed, monitored, and upgraded through unified O and M tools and processes. A Single RAN site is not restricted to a single technology - in fact, the opposite is true: it is designed specifically to host multiple technologies concurrently. It also does not require separate cabinets per technology, and it remains fully capable of receiving ongoing software upgrades and lifecycle management like any other deployment, with Single RAN describing the architectural integration rather than a static, unchangeable state.
57. 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.
58. Frage
When configuring NR-NR (5G-to-5G) neighbor relations to support mobility between two 5G cells operating on different frequency bands, which type of neighbor relation must be established?
Antwort: B
Begründung:
When two 5G NR cells operate on different frequency bands (or different carrier frequencies within the same band), mobility between them requires an inter-frequency neighbor relation to be configured. This relation must include the necessary frequency information identifying the target carrier, along with measurement configuration parameters that instruct the UE when and how to measure the candidate target frequency - since, unlike intra-frequency measurements, inter-frequency measurements typically require measurement gaps and are not performed continuously by the UE. An intra-frequency neighbor relation would only be appropriate if both cells operated on the same carrier frequency, which is not the case here. Inter-band 5G-to-
5G handovers are not automatic without configuration; the network must explicitly define the relation and measurement parameters to enable the UE to detect and report the target cell. EN-DC relations are specifically for LTE-NR dual connectivity scenarios and are unrelated to NR-NR mobility between two 5G cells.
