• Question 218:

  Regarding the usage scenarios and characteristics of various ACs, is the following description correct?

  A. A separate AC board, such as ACU2, is suitable for large-scale networks. In the future, there will be capacity expansion requirements and rack slots will be tight.
  B. Stand-alone box AC, such as AC6605, is suitable for unified construction of wired and wireless networks, and unified management of wired and wireless users.
  C. The board with the AC, such as the X1E board, is suitable for the independent management of wired and wireless users.
