Question 1

In what scenarios is GENEX Assistant typically applied? (Choose All that Apply)



Answer : A, B, D

According to Huawei's official documentation, GENEX Assistant is typically applied in the following scenarios:

Wireless network adjustment

Single site verification

Routine network optimization


Question 2

Which of the following MML commands is used to bind a physical sector to an AAU on a gNodeB?



Answer : D

According to the Huawei SA Networking Product Design Guide (https://www.huawei.com/en/doc/e_huaweidoc/pdf/HW_051525), the MML command used to bind a physical sector to an AAU on a gNodeB is 'ADD NRLOCELL'.


Question 3

After the NR base station commissioning is complete and before services go online, which of the following must be set for the NE status?



Answer : A

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'.


Question 4

In SA networking, the mobile country code (MCC) and mobile network code (MNC) information added on the gNodeB must be consistent with the PLMN information on the core network.



Answer : A

'The Mobile Country Code (MCC) and Mobile Network Code (MNC) information added on the gNodeB must be consistent with the PLMN information on the core network.'


Question 5

In the inter-site DC solution, the X2 interface can be used to implement transmission interconnection between the LTE and NR sites. Which of the following is the requirement of the transmission delay in such case?



Answer : D

The X2 interface is a signaling interface used in LTE networks to interconnect two eNodeBs (LTE base stations) to support handover and other functions. In the inter-site DC solution, the X2 interface can also be used to implement the transmission interconnection between the LTE and NR sites.

In order to ensure smooth handover and service continuity between the LTE and NR sites, it is necessary to meet the requirement of low transmission delay, which is typically <20ms. This low delay requirement is important to ensure that the handover can be completed quickly and without interruption to the ongoing service.


Question 6

If the length of the CPRI optical fiber between a BBU and an RRU exceeds 150 m, you are advised to use a multimode fiber.



Answer : A

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.


Question 7

The BBU5900 uses a modular design. Which of the following subsystems constitute the BBU? (Choose All that Apply)



Answer : A, B, C

Control subsystem: It is responsible for managing and controlling the overall operation of the BBU, it provides functions such as system initialization, software management, and alarm management.

Transmission subsystem: It is responsible for the transmission of data between the baseband subsystem and the RF subsystem, it includes functions such as data encoding, modulation, and multiplexing.

Baseband subsystem: It performs the baseband processing for the BBU, it includes functions such as demodulation, decoding, and demultiplexing.
