질문 # 26
Which statement is not true about MantaRay SON ?
정답：A
설명：
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.
질문 # 27
What is the mandatory prerequisite to implement DSS , or Dynamic Spectrum Sharing ?
정답：B
설명：
The correct answer is D .
DSS allows LTE and 5G NR to share the same spectrum dynamically , instead of requiring a separate dedicated NR carrier. Therefore, dedicated NR spectrum is not mandatory. DSS is also not limited to TDD only; it is commonly used in FDD spectrum refarming scenarios as well. Public RAN references describe DSS as a mechanism where LTE and NR coexist in the same frequency band and share spectrum dynamically.
From an SRAN architecture point of view, the mandatory deployment condition is that the radio platform must support LTE and NR coexistence on the same radio resources. That requires RF module sharing or a DSS-capable shared radio configuration.
So the correct prerequisite is:
RF module sharing.
질문 # 28
In a 5G cell , the following parameter has been modified: lowLatencyReservation = 15 .
Which percentage of UEs will be reallocated to a higher SR periodicity group whenever the threshold for moving to a higher SR periodicity group is reached?
정답：B
설명：
The correct answer is C .
In 5G uplink scheduling, SR , or Scheduling Request , is used by the UE to request uplink resources when it has data to send. SR periodicity affects uplink latency and PUCCH capacity: shorter SR periodicity gives lower latency but consumes more control-channel resources, while longer SR periodicity saves resources but increases delay.
The parameter lowLatencyReservation = 15 means 15% of the UE/resource share is reserved for the low- latency SR periodicity group. When the load threshold is reached, the remaining portion can be moved to a higher SR periodicity group.
Calculation:
100% # 15% = 85%
So the percentage of UEs that can be reallocated to a higher SR periodicity group is:
0.85 , or 85% .
질문 # 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?
정답：D
설명：
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.
질문 # 30
In the context of radio capacity management , what is the significance of Scheduling Request periodicity ?
정답：D
설명：
The correct answer is C .
Scheduling Request , or SR , is used by the UE to request uplink resources when it has uplink data to send.
The SR periodicity defines how often the UE gets an opportunity to send this scheduling request.
A shorter SR periodicity means the UE can request uplink resources more quickly, which improves uplink latency. However, it consumes more PUCCH/control-channel resources, reducing the number of UEs that can be efficiently supported.
A longer SR periodicity saves control-channel resources and can support more connected users, but it increases uplink access delay.
Therefore, SR periodicity is important because it creates a trade-off between:
Lower latency and higher connected-user capacity.
