In the inter-site DC solution, the X2 interface can be used to implement transmission interconnection between the LTE and NR sites. Which of the following is the requirement of the transmission delay in such case?
- A. <40ms
- B. <10ms
- C. <30ms
- D. <20ms
正解：D
解説：
The X2 interface is a signaling interface used in LTE networks to interconnect two eNodeBs (LTE base stations) to support handover and other functions. In the inter-site DC solution, the X2 interface can also be used to implement the transmission interconnection between the LTE and NR sites.
In order to ensure smooth handover and service continuity between the LTE and NR sites, it is necessary to meet the requirement of low transmission delay, which is typically <20ms. This low delay requirement is important to ensure that the handover can be completed quickly and without interruption to the ongoing service.

解説：
According to the official Huawei documentation, the first message sent by a gNodeB to an AMF is NGAP_INIT_UE_MSG. This message is used to initiate a connection between the gNodeB and AMF.
質問 # 24
Which of the following statements about the NR slot structure are correct? (Choose All that Apply)
- A. The symbols in a slot can be classified as downlink, uplink, or flexible.
- B. The number of symbols in one slot is fixed to 14 regardless of the subcarrier spacing configuration.
- C. Downlink self-contained slots can be used to transmit uplink data and SRSs.
- D. Downlink slots can only be used to transmit downlink data.
正解：A、C、D
解説：
1. NR downlink slots are used to transmit downlink data and control information, such as channel state information (CSI) and downlink control information (DCI). B. Downlink self-contained slots are also called as "Downlink Shared Channels (DL-SCH) slots", they can be used to transmit downlink data, but also can be used to transmit uplink control information (UCI) and sounding reference signals (SRS) in the downlink direction.
2. The symbols in a slot can be classified as downlink, uplink, or flexible, meaning that the symbols can be used to transmit data in either direction, or to transmit control information.
It's worth noting that the NR slot structure is designed to be flexible and efficient, it allows for a variable slot duration and a variable number of symbols, depending on the subcarrier spacing and the number of resource blocks used. This flexibility is intended to support a wide range of services and traffic types.
質問 # 25
After the NR base station commissioning is complete and before services go online, which of the following must be set for the NE status?
- A. Upgrade
- B. Normal
- C. Testing
- D. New
正解：B
解説：
According to the Huawei SA Networking Product Design Guide (https://www.huawei.com/en/doc/e_huaweidoc/pdf/HW_051525), after the NR base station commissioning is complete and before services go online, the NE status must be set to 'Normal'.
質問 # 26
Which of the following methods can be used to obtain VLAN IDs after a base station is powered on? (Choose All that Apply)
- A. VLAN scanning
- B. Configuration on LMT
- C. VLAN detection
- D. Remote DHCP assignment
正解：A、B、C
解説：
According to the Huawei SA Networking Product Design Guide (https://www.huawei.com/en/doc/e_huaweidoc/pdf/HW_051525), VLAN scanning is used to detect VLANs in a network. The VLAN scanning process is initiated on the base station and requires the base station to send a query to the Layer 2 switch. The query contains the VLAN ID, and the Layer 2 switch then responds with the list of interfaces that are associated with that VLAN ID. Configuration on the LMT is used to configure the VLAN and assign it to the base station. Finally, remote DHCP assignment is used to assign IP addresses to the base station from the DHCP server.

In NSA networking, which of the following modes is used to anchor 5G NR?
- A. CDMA
- B. WCDMA
- C. OGSM
- D. LTE
正解：D
解説：
The non-standalone (NSA) mode of 5G NR refers to an option of 5G NR deployment that depends on the control plane of an existing 4G LTE network for control functions, while 5G NR is exclusively focused on the user plane.[7][8] This is reported to speed up 5G adoption, however some operators and vendors have criticized prioritizing the introduction of 5G NR NSA on the grounds that it could hinder the implementation of the standalone mode of the network
質問 # 32
Which of the following can be used to check whether an antenna is reversely connected during NR single site verification?
- A. Transmission test
- B. DT around the site
- C. Fixed-point CQT
- D. VSWR test
正解：A
質問 # 33
Which of the following parameters is related to the frequency-domain position of PBCH DMRSs?
- A. PCI
- B. SI-RNTI
- C. Cell ID
- D. Bandwidth
正解：A
解説：
PCI (Physical Cell Identity) is related to the frequency-domain position of PBCH DMRSs (Physical Broadcast Channel Demodulation Reference Signals) The PBCH DMRSs are used to demodulate the Physical Broadcast Channel (PBCH) which contains system information such as the cell identity, system bandwidth, and the downlink carrier frequency.
The PBCH DMRSs are transmitted in the frequency domain, and their position is determined by the Physical Cell Identity (PCI). The PCI is a unique identifier assigned to each cell in the network, and it's used to identify the cell and its system information.
So, the correct answer is B. PCI. It's worth noting that the other parameters you mentioned are also related to the 5G system information and the cell configuration. Cell ID is a unique identifier assigned to each cell, SI-RNTI (System Information RNTI) is a unique identifier assigned to the system information, and Bandwidth is the amount of frequency resources allocated to the cell.
質問 # 34
The purpose of replaying logfiles is to reproduce the test process. The GENEX Probe can work without license in this case.
- A. False
- B. True
正解：B
解説：
According to Huawei's official documentation, the purpose of replaying logfiles is to reproduce the test process, and the GENEX Probe can work without a license in this case. This allows users to test the results of previous tests and compare them with new test results, which is useful for troubleshooting and network optimization.
