Huawei H12-322 Online Questions & Answers

• Question 71:

  The following statement about the room division device is correct?

  A. The combiner can synthesize multiple input signals and output them, and then separate and filter the mixed signals.
  B. The splitter can divide one signal equally into multiple outputs
  C. The coupler is a power splitter whose output power is not equally divided. It takes the required signal energy from the main line to the far-end antenna, and allocates more Signal energy to the proximal antenna
  D. The WLAN room sub-network generally uses a microstrip power splitter, which has low power and low cost compared to the cavity power splitter.

• Question 78:

  In any country, the use of directional antennas can significantly increase the coverage area of the WLAN.

  A. True
  B. False
  B. False

• Question 79:

  What is the correct description of the WLAN site survey for different typical scenarios?

  A. The office surveys the main load-bearing columns and partitions to cover the impact. If it is an overall suspended ceiling, the AP should be considered as close to the maintenance port, if it is metal Ceiling, you can choose to place the AP under the ceiling or wall mount
  B. If the wall of the school classroom is made of reinforced concrete, the signal attenuation is large. It is best to measure the attenuation when surveying. The teaching building should pay attention to the weak electricity room Set
  C. The ward inspection scene has high requirements for coverage field strength, roaming effect, and bandwidth requirements. At the same time, it is necessary to pay attention to the interference or disallow of medical equipment.Area with Wi-Fi signal
  D. The stadium has a complicated environment and difficult wiring. Therefore, the weak house and the wiring should be confirmed with the property. If the distance is too far, it may be considered.Adding an external switch, the survey should focus on mutual interference and installation methods between APs.

• Question 80:

  The following is a statement about the combination of the WLAN room subsystem and the existing operator room system. What is wrong?

  A. The WLAN signal is not in the same frequency band as the GSM, CDMA, 3G and other signals, and the combiner has a high isolation, so the signal between different frequency bands No interference with each other
  B. Existing room division devices (power splitter/coupler/antenna) need to support the 2.4G frequency band of WLAN, otherwise the room division device needs to be replaced.
  C. If the operator's signal can meet the coverage requirements, it can usually be satisfied after accessing the WLAN signal.
  D. There must be a parallel topology relationship between the APs, and multiple APs are not allowed to be connected in series on one branch.
  C. If the operator's signal can meet the coverage requirements, it can usually be satisfied after accessing the WLAN signal.
