• Question 206:

  What is the correct description of Huawei's spectrum navigation features?

  A. The load balancing between 2.4G and 5G radio is considered in the spectrum navigation feature of Huawei. According to the load, it is determined whether the current terminal access is from 2.4G or 5G.
  B. Determine whether the number of access users of the AP exceeds the initial threshold of load balancing between dual-frequency. If not, the STA can preferentially access the 5G radio.
  C. If the initial threshold of load balancing between dual frequencies is exceeded, the AP will calculate according to the formula (the number of users of 5G radio access - the number of users of 2.4G radio access) / the number of users of 5G radio access * 100% Compare the difference between the two RF load differences and the difference threshold between the dual-frequency load balancing to determine which frequency band the STA is allowed to access.
  D. When the number of access users of the AP reaches the initial threshold of load balancing between dual-frequency, if the number of users accessing the 5G radio-2.4G radio access users/5G radio access users* 100% > gap-threshold, the user is preferentially brought online on the 5G radio.

  B. Mesh links only transparently transmit STP packets.
  C. An STP-enabled AP does not forward STP packets to the wireless side. STP takes effect only on the AP's wired side.
  D. STP can prevent loops for multiple rings on a Mesh network.
  D. STP can prevent loops for multiple rings on a Mesh network.
