Question #1

The STR CROSFEEDTST command can be used to check for crossed feeder connections of an AAU.

Reveal Solution Hide Solution
Correct Answer: A

According to Huawei's documentation, the STR CROSFEEDTST command can be used to check for crossed feeder connections of an AAU. It is used to check whether the feeder cables of different antennas are connected to the correct ports. The command can be executed on the AAU to detect crossed feeder connections and ensure that the feeder cables are connected to the correct ports.


Question #2

Which of the following may cause exceptions In the GPS clock source?

Reveal Solution Hide Solution
Correct Answer: A, B, C, D

1. High signal attenuation is caused due to improper GPS remote distance. B. The antenna feeder between the base station and the GPS is faulty, for example, the cable is disconnected. C. The GPS is not installed in the correct position, and the number of locked satellites is less than 4. D. The GPS satellite card Is faulty.

Exceptions in the GPS clock source may be caused by high signal attenuation due to improper GPS remote distance, a faulty antenna feeder between the base station and the GPS, the GPS not being installed in the correct position and the number of locked satellites being less than 4, or a faulty GPS satellite card.


Question #3

If the subcarrier spacing (SCS) of a low-frequency cell Is 30 kHz and the bandwidth of each RB Is 360 kHz, theoretically, what value should the noise (dBm) over the air interface be?

Reveal Solution Hide Solution
Correct Answer: B

The theoretically noise (dBm) over the air interface should be -116 dBm. The noise is calculated by subtracting the noise figure of the receiver from the thermal noise floor, which is determined by the subcarrier spacing and the bandwidth of each Resource Block (RB). In this case, the subcarrier spacing is 30 kHz and the bandwidth of each RB is 360 kHz, so the thermal noise floor is -116 dBm.


Question #4

Which of the following are possible causes of NRDUCELL unavailability? (Choose All that Apply)

Reveal Solution Hide Solution
Correct Answer: A, B, C, D

According to Huawei official documentation, the following are possible causes of NRDUCELL unavailability: A. RF fault B. BBP fault C. Insufficient CPRI bandwidth D. Clock exception. The RF, BBP, and CPRI bandwidth are all important factors that contribute to the availability of the NRDUCELL. If there is a problem with any of these components, it can cause the NRDUCELL to become unavailable. Additionally, a clock exception, such as an issue with the timing or synchronization of the cell, can also cause the NRDUCELL to become unavailable.

NRDUCELL unavailability can be caused by an RF fault, a BBP fault, insufficient CPRI bandwidth, or a clock exception. According to this page, these are all possible causes of NRDUCELL unavailability.


Question #5

Which of the following methods can be used to locate faults on the user-plane path?

Reveal Solution Hide Solution
Correct Answer: C

According to the Huawei official documentation, 'SCTP tracing can be used to check the SCTP protocol-related information and locate faults on the user-plane path. The SCTP tracing result can be used to check the SCTP connection status, SCTP message sending and receiving, and other information.' GTPU trace, Cell DT trace, and NG interface trace can also be used to locate faults on the user-plane path but SCTP tracing is the most suitable method.
