質問 # 25
Which statement is not true about MantaRay SON ?
正解：C
解説：
The correct answer is B .
The statement "Energy savings management is not covered" is not true . Nokia describes MantaRay SON as supporting radio network performance, quality, and energy efficiency optimization. Nokia also references AI-powered energy savings management and RAN energy efficiency use cases under its SON/MantaRay automation portfolio.
The other statements are aligned with Nokia SON/MantaRay positioning. Nokia describes MantaRay SON as an automation layer within the MantaRay SMO framework, with support for multi-supplier/non-real-time RIC functionality and an application ecosystem. Nokia also has historical EdenNet SON material, including EdenNet SON Energy Saving Management.
Therefore, the statement that is not true is:
Energy savings management is not covered.
質問 # 26
Which of the following best describes one of the primary purposes of the Coverage and Quality use case?
正解：D
解説：
The correct answer is B .
The Coverage and Quality use case is used in network planning and optimization to identify RF problem areas. These may include:
Low RSRP or weak coverage areas
Poor SINR or low radio quality areas
High interference zones
Overshooting cells
Coverage holes
Areas where users experience poor throughput or poor accessibility
This type of use case helps NPO engineers prioritize optimization actions such as antenna tilt changes, azimuth changes, parameter tuning, neighbor optimization, power adjustment, or site expansion.
The other options are not the primary purpose:
VPN tunnel configuration is a connectivity/security task.
LCBIN-to-CSV conversion is a data processing task.
Replacing the Kronos parser is a tool-chain or troubleshooting function, not the main purpose of coverage and quality analysis.
So the best answer is:
To identify problem areas such as low coverage or high interference.
質問 # 27
At which mark are all conditions fulfilled for energy saving , so the cell will be switched off? Refer to the image below.
正解：A
解説：
The correct answer is B , which corresponds to mark C in the diagram.
In the diagram, the energy-saving process follows these stages:
Before mark B , the cell is entering the power-saving period, but the required load condition has not yet been satisfied for the required duration.
At mark B , the measured load has gone below the configured threshold, but the cell is not switched off immediately. The system must confirm that the load remains below the required threshold for the configured time.
At mark C , the load has stayed below the required threshold for the required duration, shown as 5 minutes in the diagram. At this point, all conditions are fulfilled, and the cell can be switched off. The diagram also shows the state becoming:
energySavingState = energySaving
Marks D and E are already inside or near the later part of the power-saving period. Mark E is associated with operator suspension/exit behavior, not the initial moment when all switch-off conditions are first fulfilled.
質問 # 28
During an intra-gNB DU handover , what is the role of the RRC Reconfiguration message sent by the gNB- CU to the UE?
正解：D
解説：
The correct answer is A .
During an intra-gNB DU handover , the UE is moved from one cell/DU resource to another under the same gNB-CU control. The gNB-CU coordinates the handover preparation and sends an RRC Reconfiguration message to the UE.
The role of this message is to provide the UE with the required handover command information, such as:
Target PCell configuration
Radio resource configuration
Mobility control information
Random access configuration, when needed
Measurement or reconfiguration-related information
After receiving the RRC Reconfiguration , the UE performs the handover execution procedure toward the target cell and later responds with RRC Reconfiguration Complete .
Option B is incorrect because admission control and source-cell scheduling suspension are internal network- side procedures, not the UE-facing role of the RRC Reconfiguration message.
Option C is not the best answer because user-plane resource transfer is handled between gNB-CU/gNB-DU functions, while dedicated preamble allocation may be part of the configuration but is not the main purpose of the message.
Option D is incorrect because RLC reestablishment and PDCP recovery are lower-layer/user-plane handling actions, not the primary purpose of the RRC Reconfiguration message.
Therefore, the correct role is:
It instructs the UE to perform handover to the target PCell and provides measurement/configuration information.
質問 # 29
In a high-mobility network, the maximum cell size must be restricted to 33 km . Which PRACH format and restricted-set type should be used?
正解：B
解説：
The correct answer is Format 1 / Type B .
For PRACH planning, the selected preamble format must support the required cell radius. Format 0 is too short for a 33 km cell because it is typically suitable only up to around 14.5 km . Format 2 is also not suitable because its practical maximum cell radius is around 29.5 km , which is below the required 33 km . Therefore, a longer PRACH format is needed.
Because the scenario mentions high mobility , an unrestricted PRACH set is not preferred. High-mobility environments require a restricted set to handle Doppler effects and reduce ambiguity in PRACH preamble detection. Between the restricted-set options, Type B is the correct choice for this 33 km high-mobility case.
A matching Nokia-style question source also lists this exact scenario with Format 1 / Type B as option A.
