Huawei H12-321 Online Questions & Answers

• Question 101:

  When the AP receives a Probe request from 2.4G, if it can only receive a 2.4G Probe request for a continuous period of time, it considers that the terminal only supports the 2.4G band; otherwise, the terminal is considered to be a dual-band terminal. This logic also applies to 5G radios.

  A. Correct
  B. False
  A. Correct

• Question 102:

  What does OU in the directory server refer to?

  A. User
  B. User group
  C. Organization unit
  D. Domain
  C. Organization unit

• Question 103:

  Which of the following commands is used to create a radio calibration profile?

  A. [AC-wlan-view] rrm-profile name wlan-net
  B. [AC-wlan-view] regulatory-domain-profile name domain1
  C. [AC-wlan-view] wired-port-profile name wired-port
  D. [AC-wlan-view] ap-system-profile name mesh-sys
  A. [AC-wlan-view] rrm-profile name wlan-net

• Question 104:

  What is wrong with the following statement about power adjustment?

  A. The transmit power of the AP determines the coverage of its RF signal. The larger the AP power, the larger its coverage.
  B. The global tuning algorithm mainly includes the dynamic channel adjustment algorithm TPC and the transmission power control algorithm DCA.
  C. The traditional RF power control method only statically sets the transmit power to the maximum value, simply pursuing the signal coverage, but excessive power may cause unnecessary interference to other wireless devices.
  D. When dynamically adjusting power, it is necessary to choose an optimal power that balances coverage and signal quality.
  B. The global tuning algorithm mainly includes the dynamic channel adjustment algorithm TPC and the transmission power control algorithm DCA.

• Question 109:

  Radar systems in some areas operate in the 5G band and interfere with AP RF signals operating in the 5G band. With the DFS function, when the AP detects that there is interference in the frequency band of its working channel, engineers need to manually switch the working channel.

  A. Correct
  B. False
  B. False
