Huawei H35-481_V2.0 Exam Dumps

The UBBP board is added to the base station when it is reset, and you need to log in to the LMT again in order to access the new UBBP board. The UBBP board is used for configuration, monitoring, and maintenance of the base station.

According to Huawei's official documentation, when the UBBP (Universal Baseband Processing) board is added, the base station is reset and you need to log in to the LMT (Local Management Terminal) again. The addition of other boards (OUMPT, UPEU, UEIU) may not require a reset and re-login.

In 5G Core network, the core network subscription information contains parameters that are used to manage the resources of a UE.

1. UE-AMBR (UE Aggregate Maximum Bit Rate) : It's the maximum bit rate that is allocated to a UE for non-guaranteed bit rate (non-GBR) services. It controls the non-GBR rate for a UE.

In 5G NR, the Master Information Block (MIB) message is transmitted on the Physical Broadcast Channel (PBCH) and contains information that is used by the UEs to synchronize to the cell and obtain basic system information. The parameters in the NR MIB message that indicate the time-domain position of CORESET 0 are the least significant four bits of PDCCH-configSIBl.

According to Huawei official documentation, B. Batch reconfiguration of NEs is a scenario that can be performed using the radio data planning file in the MAE-Deployment. The radio data planning file can be used to perform batch reconfiguration of NEs, such as the configuration of multiple NEs in a batch. The radio data planning file can be used to import data, perform parameter configuration, and export the configuration results. The other options are not performed using the radio data planning file in the MAE-Deployment.

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.
