Huawei HCIP-5G-RAN V2.0 H35-481_V2.0 Exam Questions

Answer : B, D

Answer : A

When a GPS divider is used, the maximum distance between the GPS antenna and the BBU is shortened. This is because the divider splits the signal from the antenna into multiple signals that can be distributed to multiple BBUs, thus reducing the distance between the antenna and the BBUs.

Answer : A, B, C

In the data reconfiguration using the MAE-Deployment, the MOs gNodeBFuncrjon, gNBCULogicNode, and gNBDULogicNode are involved. These MOs are responsible for configuring the gNodeB functional parameters, the gNodeB CU logical nodes and the gNodeB DU logical nodes.

Answer : A, B, C

During a cell search, a UE uses synchronization signals to synchronize to a cell and obtain basic system information. The synchronization rasters that can be used by a UE during a cell search are:

1. 17.28MHz: This is the synchronization raster that is used for the primary synchronization signal (PSS) and the secondary synchronization signal (SSS) in 5G NR.

2. 1200kHz: This is the synchronization raster that is used for the primary synchronization signal (PSS) and the secondary synchronization signal (SSS) in 4G LTE.

3. 1.44MHz: This is the synchronization raster that is used for the cell-specific reference signal (CRS) in 4G LTE.

Answer : D

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.

Answer : A, C, D

The functions of SRSs in NR include downlink beamforming weight calculation, obtaining the uplink channel quality, and uplink beam management. Uplink grants are not related to SRSs.

Answer : A

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
