質問 # 13
Which of the following scenario using the radio data planning file In the MAE-Deployment?
- A. Batch reconfiguration of NEs
- B. Configuration of parameters in multiple MOs
- C. Reconfiguration of a single NE
- D. Configuration of parameters in an MO
正解：A
解説：
According to Huawei official documentation, B. Batch reconfiguration of NEs is a scenario that can be performed using the radio data planning file in the MAE-Deployment. The radio data planning file can be used to perform batch reconfiguration of NEs, such as the configuration of multiple NEs in a batch. The radio data planning file can be used to import data, perform parameter configuration, and export the configuration results. The other options are not performed using the radio data planning file in the MAE-Deployment.

解説：
The GUI configuration mode in MAE-Deployment can be used to configure parameters in an MO and reconfigure a single NE. It cannot be used to configure parameters in multiple MOs or to batch reconfigure multiple NEs. According to the Huawei official documentation, "The GUI configuration mode can be used to configure parameters in an MO and reconfigure a single NE. However, it cannot be used to configure parameters in multiple MOs or to batch reconfigure multiple NEs."
質問 # 15
In NSA networking, X2 self-setup between a gNodeB and an eNodeB requires that the gNodeB and eNodeB be managed by the same OSS.
- A. False
- B. True
正解：B
解説：
In Non-standalone (NSA) networking, X2 self-setup between a gNodeB and an eNodeB requires that the gNodeB and eNodeB be managed by the same OSS. Because gNodeB and eNodeB are managed by the same OSS, the OSS can configure the X2 self-setup parameters, such as the X2 self-setup switch, the X2 interface IP address, and the X2 self-setup trigger conditions. Only when the gNodeB and eNodeB are managed by the same OSS and configured with the same X2 self-setup parameters, the gNodeB and eNodeB can establish an X2 self-setup connection.
質問 # 16
In SA networking, incorrect TAC configurations will cause UE access to fail.
- A. False
- B. True
正解：B
解説：
In SA networking, incorrect TAC configurations will cause UE access to fail. This is because the UE must be assigned a specific TAC value in order to be allowed to access the network. If the TAC value is incorrect, the UE will not be able to access the network. Reference: https://www.qualcomm.com/invention/5g/standalone-networking-5g-sa-networks
質問 # 17
Unlike 4G base stations, 5G base stations do not need to be configured with tracking area Information.
- A. False
- B. True
正解：A
解説：
Unlike 4G base stations, 5G base stations do need to be configured with tracking area Information. In 4G, tracking area information is used to identify the area where the mobile device is located and to control the paging process. In 5G, however, tracking area information is used to identify the area where the mobile device is located and to control the paging process as well as to manage the mobility of the mobile device in the 5G network. The tracking area information is also used for the initial registration of the mobile device and for handover between cells.
質問 # 18
The PING, TRACERT, CFMTRACE, CFMPING, and UDPECHO commands cannot be executed simultaneously on the same board in a gNodeB.
- A. False
- B. True
正解：B
解説：
The PING, TRACERT, CFMTRACE, CFMPING, and UDPECHO commands cannot be executed simultaneously on the same board in a gNodeB. Executing multiple commands at the same time can cause system instability, so it is not recommended to do so.
質問 # 19
The STR CROSFEEDTST command can be used to check for crossed feeder connections of an AAU.
- A. False
- B. True
正解：B
質問 # 20
The segmentation method is the most important method for isolating faults on the transport network. Different methods are used for different fault types.
- A. False
- B. True
正解：B
解説：
The segmentation method is the most important method for isolating faults on the transport network. Different methods are used for different fault types, such as Optical Time Domain Reflectometry (OTDR) for fiber faults, Radio Frequency Interference Measurement (RFI) for radio interference, and Signal-to-Noise Ratio (SNR) for signal noise. By segmenting the network, faults can be easily identified and isolated.

質問 # 21
Which of the following statements about PDSCH DMR5 is incorrect?
- A. The start symbol of a front-loaded DMRS of a type A PDSCH can be symbol 2.
- B. The front-loaded DMRS is mandatory, and the additional DMRS is optional.
- C. The overhead of type 1 DMRS is less than that of type 2 DMRS.
- D. The start symbol of a front-loaded DMRS of a type B PDSCH is always the first symbol of PDSCH.
正解：C
質問 # 22
If the NRDUCELL corresponding to NRCELL Is not set up, the NRCELL must be unavailable.
- A. False
- B. True
正解：B
解説：
If the NRDUCELL corresponding to NRCELL is not set up, then the NRCELL must be unavailable. This is because the NRDUCELL defines the coverage area of an NRCELL. Without the NRDUCELL, the NRCELL cannot be successfully activated and therefore it will remain unavailable.

- B. PDSCH scheduling
- C. PUSCH scheduling
- D. PUSCH power control
正解：D
解説：
According to the official 3GPP specification, the DCI of NR does not carry PUSCH power control information. It carries scheduling information for the PUSCH and PDSCH and a PMI report. Reference: https://www.3gpp.org/DynaReport/38-series.htm
質問 # 27
Which of the following parameters In the NR MIB message indicates the time-domain position of CORESET 0?
- A. Most significant four bits of PDCCH-configSIBl
- B. SSB-subcarrier offset
- C. Least significant four bits of PDCCH-configSIBl

Which of the following are the topologies between a BBU and RF units?
- A. Tree topology
- B. Ring topology
- C. Star topology
- D. Chain topology
正解：A、C、D
解説：
The following are the common topologies used between a BBU (Baseband Unit) and RF (Radio Frequency) units:
1. Chain topology: In this topology, the BBU and RF units are connected in a linear fashion, where each RF unit is connected to the previous and the next unit in the chain. B. Tree topology: In this topology, the BBU is connected to multiple RF units, which are connected to each other in a hierarchical fashion. D. Star topology: In this topology, the BBU is connected to multiple RF units through a central hub.
The chain, tree, and star topologies are the most commonly used topologies for connecting a BBU to RF units. The ring topology is not commonly used for this type of connection.
