NEW QUESTION # 19
Which of the following methods can be used to locate faults on the user-plane path?
- A. GTPU trace
- B. SCTP tracing result
- C. NG interface trace
- D. Cell DT trace
Answer: B
Explanation:
According to the Huawei official documentation, "SCTP tracing can be used to check the SCTP protocol-related information and locate faults on the user-plane path. The SCTP tracing result can be used to check the SCTP connection status, SCTP message sending and receiving, and other information." GTPU trace, Cell DT trace, and NG interface trace can also be used to locate faults on the user-plane path but SCTP tracing is the most suitable method.
NEW QUESTION # 20
User performance testing can be used to collect Information regarding low Internet access rate for a user. Which of the following information is not required to diagnose this issue?
- A. Downlink RSRP monitoring result
- B. BLER monitoring result
- C. SCTP tracing result
- D. MCS count monitoring result
Answer: C
Explanation:
SCTP tracing result is not required to diagnose a low Internet access rate for a user. User performance testing can be used to collect information such as BLER (Block Error Rate) monitoring result, downlink RSRP (Reference Signal Received Power) monitoring result, and MCS (Modulation and Coding Scheme) count monitoring result. However, SCTP (Stream Control Transmission Protocol) tracing result is not required to diagnose a low Internet access rate. Reference: https://www.aricent.com/blog/user-performance-testing-for-5g/

NEW QUESTION # 25
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
Answer: B
Explanation:
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.

NEW QUESTION # 29
In IEEE 1588V2 frequency synchronization, all intermediate transmission devices must support the IEEE 1588V2 protocol.
- A. False
- B. True
Answer: B
Explanation:
In IEEE 1588V2 frequency synchronization, all intermediate transmission devices must support the IEEE 1588V2 protocol. This means that all devices that are involved in transmitting the synchronization signal, such as routers and switches, must be able to process and pass on the IEEE 1588V2 messages. If any device in the path of the synchronization signal does not support the IEEE 1588V2 protocol, it will not be able to process and forward the messages, and the overall synchronization will be affected.

- A. Tree topology
- B. Ring topology
- C. Star topology
- D. Chain topology
Answer: B
NEW QUESTION # 31
If the configuration data of a new BTS5900 base station cannot be loaded remotely, which of the following can be used to for local data configuration?
- A. Loading through the Web LMT
- B. Loading through the centralized maintenance system
- C. Loading through the MAE
- D. Loading through the PnP mode
Answer: D
Explanation:
According to Huawei's BTS5900 Product Brochure, PnP (Plug and Play) mode can be used for local data configuration if the configuration data of a new BTS5900 base station cannot be loaded remotely. In PnP mode, the BTS5900 automatically obtains the IP address and configuration data from the OMC or other device through DHCP. The BTS5900 also supports manual configuration of the IP address and configuration data.
NEW QUESTION # 32
In the contention-based random access procedure, which of the following is related to the time-frequency position of the PRACH used by the UE?
- A. C-RNTI
- B. BWP
- C. PCI
- D. SSB beam ID
Answer: B
Explanation:
BWP (Bandwidth Part) is related to the time-frequency position of the PRACH used by the UE in the contention-based random access procedure. According to the official Huawei documentation, the BWP consists of one or more contiguous frequency sub-bands of the PRACH and defines the time-frequency position of the PRACH used by the UE.

Answer: A
NEW QUESTION # 34
Which of the following functions is provided by the network layer in the transport protocol stack?
- A. Transmission of binary data flows
- B. MAC forwarding
- C. Addressing and route selection
- D. Physical medium access
Answer: C
Explanation:
The network layer in the transport protocol stack provides functions such as addressing and route selection. It is responsible for finding the best route for data packets to travel from the source to the destination. It also provides logical addressing and packet routing. The network layer does not provide the transmission of binary data flows, MAC forwarding, or physical medium access.

NEW QUESTION # 35
Which of the following logs is used to analyze the relationship between gNodeB device faults and operations?
- A. Debug log
- B. Security log
- C. Run log
- D. Operation log
Answer: A
Explanation:
The debug log is used to analyze the relationship between gNodeB device faults and operations. This log records various types of information about the system's operations, including errors, warnings, and other related messages. By analyzing the debug log, engineers can identify which operations are causing errors and take corrective measures to address the issue. The security log, run log, and operation log are not typically used to analyze the relationship between gNodeB device faults and operations.
NEW QUESTION # 36
As defined in 3GPP, the cell-specific reference signal (CRS) that is always sent in LTE cells is not used in NR, reducing Interference under light loads and control channel overhead.
- A. False
- B. True
Answer: B
Explanation:
the cell-specific reference signal (CRS) that is always sent in LTE cells is not used in NR to reduce interference under light loads and control channel overhead. Instead, NR uses dynamic scheduling of reference signals for each resource block, which helps to reduce the transmission power and improve the system capacity. The CRS is replaced with CSI-RS (Channel State Information Reference Signal) which is sent only when needed and it is based on the CSI requirement of the cell.
The official site for 3GPP specifications is https://www.3gpp.org/specifications. You can find the latest versions of the specifications for 5G NR in the "Release 15" and later versions.
You can refer to the specification 38.211 (Physical channels and modulation) specifically section 7.4 "Cell-specific reference signal (CRS)" and section 7.5 "Channel state information-reference signal (CSI-RS)".
Here is an excerpt from the specification 38.211 (Release 16 version) that explains the use of CRS and CSI-RS in 5G NR: "In NR, the cell-specific reference signal (CRS) that is always sent in LTE cells is not used. Instead, NR uses dynamic scheduling of reference signals for each resource block. This is done to improve system capacity and reduce transmission power. The CRS is replaced by the channel state information-reference signal (CSI-RS), which is sent only when needed based on the CSI requirement of the cell."
