質問 # 30
Which of the following methods can be used to locate faults on the user-plane path?

A. GTPU trace
B. Cell DT trace
C. NG interface trace
D. SCTP tracing result

正解：D

解説：
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.

質問 # 31
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.

質問 # 33
If multiple IP addresses with different next hop addresses are planned for the gNodeB, which of the following route configuration modes is not applicable?

A. Destination address route configuration
B. Source address route configuration
C. Direct route configuration

正解：A

解説：
The destination address route configuration is not applicable when multiple IP addresses with different next hop addresses are planned for the gNodeB. Destination address route configuration is used when a single IP address is used by the gNodeB and the next hop address and outgoing interface do not need to be configured. In the case of multiple IP addresses with different next hop addresses, direct route configuration should be used. Direct route configuration requires that the IP address, next hop address, and outgoing interface all be specified for each IP address.

質問 # 34
Which of the following commands is used to map DSCPs and VLAN priorities?

A. MOD PHBMAP
B. SET PHBMAP
C. MOD DSCPMAP
D. SET DSCPMAP

正解：B

解説：
The SET PHBMAP command is used to map DSCPs and VLAN priorities. This command is used to configure the PHB mapping table for DSCP and VLAN priority, which will determine how the network will prioritize traffic.

質問 # 40
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：D

解説：
The statement "The start symbol of a front-loaded DMRS of a type B PDSCH is always the first symbol of PDSCH" is incorrect. In 5G NR, the start symbol of a front-loaded DMRS of a type B PDSCH can be configured as the first symbol of PDSCH or as the second symbol of PDSCH.
You can refer to the Huawei official documentation for HCIP-5G-RAN V2.0 certification and the 3GPP 5G NR standard (38.211, 38.212, 38.213) for more information on PDSCH DMRS, including the configurations of the front-loaded DMRS, the DMRS symbols and the optional and mandatory nature of it.
Here are some official references:

The STR CROSFEEDTST command can be used to check for crossed feeder connections of an AAU.

A. False
B. True

正解：B

解説：
According to Huawei's documentation, the STR CROSFEEDTST command can be used to check for crossed feeder connections of an AAU. It is used to check whether the feeder cables of different antennas are connected to the correct ports. The command can be executed on the AAU to detect crossed feeder connections and ensure that the feeder cables are connected to the correct ports.

質問 # 42
What is the typical output power of a 64T64R AAU?

A. 200W
B. 80W
C. 20W
D. 40W

正解：D

解説：
According to Huawei's 5G AAU Product Brochure, a 64T64R AAU typically has a maximum output power of 40W. This power is split between the 64 transmitters, so each transmitter has an output power of 0.625W. The output power of an AAU can be adjusted depending on the specific requirements.

質問 # 44
If the dock of a base station is locked and the base station fails to obtain clock source signals, which of the following clock states is the base station in?

A. Free running
B. Holdover
C. Fast tracking
D. Locked

正解：B

解説：
The base station is in a Holdover state when the dock of a base station is locked and the base station fails to obtain clock source signals. Holdover is a state during which the base station uses the last known frequency and time information to maintain synchronization and clock accuracy. According to the Huawei official documentation, "when the clock source is lost, the base station enters the holdover state. In the holdover state, the base station uses the last known frequency and time information to maintain synchronization and clock accuracy. Holdover time is the duration for which the base station can maintain synchronization after the clock source is lost."

質問 # 45
Which of the following functions is provided by the network layer in the transport protocol stack?

A. MAC forwarding
B. Addressing and route selection
C. Physical medium access
D. Transmission of binary data flows

正解：B

解説：
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.

質問 # 47
Unlike 4G base stations, 5G base stations do not need to be configured with tracking area Information.

A. True
B. False

正解：B

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 # 51
In NSA networking, which of the following objects are unnecessary to configrued for a gNodeB in SI self-setup scenarios?

A. SCTPHOST
B. SCTPPEER
C. USERPLANEPEER
D. USERPLANEHOST

正解：A

質問 # 52
In NSA networking, which of the following objects are unnecessary to configrued for a gNodeB in SI self-setup scenarios?

A. SCTPHOST
B. SCTPPEER
C. USERPLANEPEER
D. USERPLANEHOST

正解：A、D

解説：
In NSA networking, In self-setup scenarios, the USERPLANEHOST and SCTPHOST objects are unnecessary to configure for a gNodeB. The USERPLANEHOST object is used to configure the IP address of the user plane host, and the SCTPHOST object is used to configure the IP address of the SCTP host. In self-setup scenarios, the gNodeB automatically obtains the IP addresses of the user plane host and SCTP host from the S1-MME or S1-U peer. The USERPLANEPEER and SCTPPEER objects are necessary to configure for a gNodeB in SI self-setup scenarios. They are used to configure the IP address of the user plane peer and SCTP peer, respectively.
