질문 # 22
In a 5G NSA Option 3x deployment, why should we not define 5G neighbors in LTE sectors where there is no 5G coverage ?
정답：C
설명：
The correct answer is A .
In 5G NSA Option 3x , LTE acts as the Master Cell Group , and NR acts as the Secondary Cell Group , usually added through EN-DC . If 5G NR neighbors are configured in an LTE sector where there is actually no 5G coverage , the LTE eNB may still configure the UE to perform NR measurements.
To perform NR inter-RAT or inter-frequency measurements, the UE may require measurement gaps .
During these gaps, the UE stops normal LTE reception/transmission activities to measure NR frequencies. If there is no real 5G coverage, those gaps become wasted measurement time and can reduce LTE user throughput.
Option B is not the best answer because if there is no 5G coverage, the main issue is not successful SCG addition or handover degradation, but unnecessary measurement activity. Option C is also not correct because redirection from 5G to 4G normally occurs when the UE is already on or connected to 5G coverage, which is not the case here.
Therefore, the main reason is:
LTE throughput degradation due to unnecessary measurement gap configuration.
질문 # 23
Identify the missing network components X, Y, and Z in the architecture diagram.
정답：B
설명：
The correct answer is B .
In the 5G Core , component X is connected to:
N2 from NG-RAN
N11 toward SMF
N15 toward PCF
N26 toward the EPC mobility entity
These are typical interfaces of the AMF , or Access and Mobility Management Function . Therefore, X = AMF .
In the EPC , component Z is connected to:
S1-MME from eNB
S11 toward the gateway
N26 toward the 5GC AMF
These are typical interfaces of the MME , or Mobility Management Entity . Therefore, Z = MME .
Component Y is outside the core user-plane path and represents the external service network connected through N6/SGi , commonly shown as IMS in voice-service architecture diagrams. Therefore, Y = IMS .
So the correct mapping is:
X: AMF, Y: IMS, Z: MME.
질문 # 24
Which parameter defines the PRACH format ?
정답：B
설명：
The correct answer is B .
The prachConfigurationIndex defines the PRACH configuration, including the PRACH time-domain occasions and the associated PRACH format according to the PRACH configuration tables. In 5G NR, PRACH configuration is based on 3GPP-defined PRACH tables, where the configuration index maps to the PRACH format and PRACH occasion structure.
The other options have different meanings:
A). msg1-FrequencyStart defines the frequency-domain starting position of PRACH occasion resources.
C). prachRootSequenceIndex defines the root sequence used for PRACH preamble generation.
D). totalNumberOfRAPreambles defines how many random access preambles are available.
Therefore, the parameter that defines the PRACH format is:
prachConfigurationIndex.
질문 # 25
At which mark are all conditions fulfilled for energy saving , so the cell will be switched off? Refer to the image below.
정답：D
설명：
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.
질문 # 26
Evaluate the impact of using MantaRay SON's centralized PCI optimization module compared to distributed SON implementations.
정답：B
설명：
The correct answer is C .
A centralized SON approach has broader network-level visibility than a purely distributed implementation.
For PCI optimization , this is important because PCI conflicts, PCI confusion, and neighbor-related PCI issues are not always local to one cell. They may involve several neighboring cells, multiple layers, and sometimes multiple vendors.
Nokia positions MantaRay SON as a centralized, AI-powered network optimization and automation platform for improving RAN quality, efficiency, and customer experience. Nokia also describes MantaRay SON as supporting multi-supplier/non-real-time RIC functionality in the MantaRay SMO framework.
So compared with distributed SON, centralized PCI optimization can better analyze wider-area PCI relationships and resolve PCI problems across multi-vendor or multi-layer networks.
Therefore, the correct statement is:
Centralized PCI optimization can identify and resolve PCI issues across multi-vendor networks.
