H35-481_V2.0 Practice Exam Questions with Answers HCIP-5G-RAN V2.0 Exam Certification

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.

One of the challenges of 5G network construction is to provide Indoor coverage in large stadiums, where Indoor interference severely affects network coverage and capacity. One of the solutions that can effectively mitigate the interference caused by Indoor coverage with high-density site deployment is sector splitting. This solution involves dividing the cell into multiple smaller cells, each with its own set of antennas and RF parameters. By reducing the number of users and devices in each cell, sector splitting can significantly reduce the amount of interference and improve network coverage and capacity.

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

In 5G NR, the master information block (MIB) is a control message that is transmitted by the base station on the Physical Broadcast Channel (PBCH). The MIB contains the following information:

A. System frame number: The MIB contains the system frame number (SFN) which is used to identify the current frame in the system.

B. PDCCH ConfigSIB1: The MIB contains the PDCCH (Physical Downlink Control Channel) configuration for the SIB1 (System Information Block 1) which is used to transmit system information to the UE.

C. dmrs-TypeA-Position: The MIB contains the position of the dmrs-TypeA (Diversity and Multiplexing Configuration Reference Signal) which is used to transmit a reference signal for demodulation and channel estimation.

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.

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.

In a gNodeB, the time information is synchronized from the OSS using the Network Time Protocol (NTP). The ADD NTPC command is used to configure the IP address of the NTP server, which is the time server that the gNodeB synchronizes with. This command is used to specify the IP address of the NTP server, the NTP version, and other parameters related to time synchronization.

According to Huawei official documentation, When the RUN indicator of an AAU is blinking green (on for 1s and off for 1s), it means that the software is being loaded to the board, or the board is not started.

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.

In 5G NR, the random access procedure is used by a UE to establish a connection with the base station. The channels involved in the NR random access of a UE are:

A. PDCCH (Physical Downlink Control Channel): The PDCCH is used by the base station to transmit control information to the UE, such as scheduling assignments and uplink grants.

B. PRACH (Physical Random Access Channel): The PRACH is used by the UE to transmit the random access preamble to the base station.

D. PUCCH (Physical Uplink Control Channel): The PUCCH is used by the UE to transmit control information to the base station, such as uplink scheduling requests and HARQ feedback.

C. PUSCH (Physical Uplink Shared Channel) is not involved in NR random access of a UE, it is a shared channel used to transmit the uplink data and control information.

After the PA reconfiguration of a 5G base station in SA networking, it is necessary to check whether cell-related alarms are reported, whether the 5G cell services are normal, and whether the PCI on the NR side has taken effect on the NE. These checks are necessary to ensure that the reconfiguration has been successful.

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.
