Huawei H35-480_V3.0 HCIA-5G-RAN V3.0 Exam Exam Practice Test

H110V6 refers to a scenario where there are 110 horizontal and 6 vertical antenna elements installed on the gNodeB, which is ideal for providing coverage in high-rise office buildings. The high number of horizontal antenna elements allows for high-density deployment, which can improve the coverage and capacity of the network in these types of environments.

End-to-end (E2E) network device update is required for the evolution from 5G Non-Stand-Alone (NSA) networking to Stand-Alone (SA) networking. In 5G NSA networking, the control plane functions are handled by the 4G LTE network, while the user plane functions are handled by the 5G NR network. In contrast, in 5G SA networking, the control plane and user plane functions are handled by the 5G NR network alone. So, to evolve from 5G NSA to 5G SA, all the network devices including Radio Access Network (RAN), Core Network (CN) and Transport Network (TN) need to be updated with 5G SA capable software and hardware.

It is important to note that 5G SA provides more flexibility, control and autonomy for network operation and management, However, it also requires a higher level of complexity and more resources to operate.

According to Huawei's official documentation, gNodeBs send TPC (Transmit Power Control) commands to UEs over PDCCHs to control the transmit power of PUCCH (Physical Uplink Control Channel) and PUSCH (Physical Uplink Shared Channel).

The Common Public Radio Interface (CPRI) is a standard that defines the interface between the BBU (baseband unit) and the RRU (remote radio unit) in a wireless base station. The BBU and the RRU are connected by an optical fiber cable, known as the CPRI optical fiber.

The CPRI optical fiber is used to transport the digital baseband signals between the BBU and the RRU. The distance between the BBU and the RRU can be up to several kilometers, but the standard CPRI specification only supports a maximum distance of 150m between the BBU and RRU using single-mode fiber. If the distance exceeds 150m, multimode fiber should be used to extend the distance between the BBU and the RRU.

According to the official Huawei documentation, the possible causes for a 4G cell not delivering B1 measurement configurations during a 5G service test are that the UE does not support EN-DC, the NSA switch is not turned on, or neighboring LTE cells and SCGs are not configured.

-"In single site verification, the typical ping packet size is 32 bytes and 1500 bytes, the typical interval is 1s." in Huawei official website.

A. Mixed slot is a slot configuration in which at least one downlink/uplink symbol is present, while other symbols can be flexibly configured for downlink or uplink transmission. This allows for a more efficient use of resources and better support for different types of services. B. Flexible-slot is a slot configuration in which all symbols are flexibly configured for downlink or uplink transmission. This allows for a more efficient use of resources and better support for different types of services. C. Downlink-only slot is a slot configuration in which all symbols are dedicated for downlink transmission, This configuration is mainly used for downlink-centric services such as video streaming or software downloads. D. Uplink-only slot is a slot configuration in which all symbols are dedicated for uplink transmission, this configuration is mainly used for uplink-centric services such as voice calls or video conferencing.

According to the Huawei SA Networking Product Design Guide (https://www.huawei.com/en/doc/e_huaweidoc/pdf/HW_051525), after the NR base station commissioning is complete and before services go online, the NE status must be set to ‘Normal’.

The correct MML command to query version information relating to the software stored on the gNodeB is LST SOFTWARE. This command will list the version information of the software installed on the gNodeB, including the version numbers, software names, and more. This is stated in the official Huawei documentation, which states: "Use the LST SOFTWARE command to check the version information of the software installed on the gNodeB, including the version numbers, software names, and more."
