  1. 1
  2. 2
  3. 3
  4. Multiple

Answer(s): D



Which of the following antennas is recommended for the AP9330DN in a WLAN scenario where the room is large and the capacity is high?

  1. Single-flow single-frequency omnidirectional antenna
  2. Single-current dual-frequency omnidirectional antenna
  3. Dual-current single-frequency directional antenna
  4. Dual-stream dual-frequency directional antenna

Answer(s): D



Basic requirements for WLAN network construction include bandwidth requirements, coverage targets, coverage methods, field strength requirements, and power distribution methods.
Determining the strength of the coverage area in the field strength requirement is adjusted by the AP transmit power. The following statements are correct regarding the requirements that the network regulation needs to consider in advance. Is it?

  1. The field strength demand in key areas is that the main online area of the user can be controlled at
    -40~-80dBm. If the power is too strong, it will easily lead to receiving overload, and the power is too weak.
    Will cause the connection rate to drop
  2. The interference field strength requirement is that the same-frequency interference in the same area is not more than -80dBm
  3. The fringe field strength level combined with the receiving sensitivity and edge bandwidth requirements are generally selected above -75dBm
  4. The leakage field strength of the system should not be too large, and the field strength at 10m of the external network of the building cannot be greater than -90dBm.

Answer(s): B,C,D



Which of the following authentication methods has the longest roaming time?

  1. OPEN
  2. 802.1x certification
  3. WEP+PSK
  4. Portal

Answer(s): B

This country supports 1-13 channels)

  1. True
  2. False

Answer(s): A
