Huawei Huawei Certification H12-322 Questions & Answers

• Question 21:

  In a certain room subsystem, using the AP9330DN, each incoming antenna can be set to a different channel to avoid co-channel interference.

  A. True

  B. Falses

  Correct Answer: B

• Question 22:

  The following options are incorrect about the WLAN forwarding mode description?

  A. The WLAN forwarding model includes two modes: local forwarding mode and centralized forwarding mode.

  B. The data forwarding mode of the datagram is also called the tunnel forwarding mode. The service data packets are uniformly encapsulated by the AP and then forwarded to the AC.Line-to-AP management, also acting as a forwarding hub for AP traffic

  C. The datagram is forwarded in text, that is, the AP management flow is encapsulated in the CAPWAP tunnel and reaches the AC termination; the AP service flow is not encapsulated by the CAPWAP.Directly sent by the AP to the switching device for direct forwarding

  D. The data packet is forwarded in a centralized manner, that is, the AP management flow is

  encapsulated in the CAPWAP tunnel and the AC is terminated. The AP service flow is not encapsulated by the CAPWAP.Directly sent by the AP to the switching device for direct forwarding

  Correct Answer: BD

• Question 23:

  The throughput test of the wireless terminal in the WLAN wireless city scenario, the following description is correct under the same conditions?

  A. TCP flow is larger than UDP flow

  B. TCP flow is equal to UDP flow

  C. TCP flow is smaller than UDP flow

  D. Other options are wrong.

  Correct Answer: C
