Huawei HCIP-WLAN CEWA(Huawei Certified ICT Professional-Wireless Local Area Network-Constructing Enterprise WLAN Architecture) Sample Questions:

1. Which of the following statement is TRUE about AC functions in the implementation of radio calibration?

A) The AC maintains AP neighbor topology information according to the radio environment information sent by APs.
B) The channel adjustment and power adjustment algorithms in radio calibration are coupled with each other, and the AC needs to consider their influence to each other.
C) The AC sends alarms, such as the AP offline alarms to the network management system.
D) The AC runs the radio calibration algorithm to coordinate and allocate channels and transmit power of APs.

2. Which statements about roaming are TRUE? (Multiple Choice)

A) The APs an STA connects to before and after roaming must work in the same channel.
B) The APs an STA connects to before and after roaming can work in different channels.
C) During roaming, the STA sends an association request containing information about the original AP to the new AP.
D) During roaming, the STA sends a re-association request containing information about the original AP to the new AP.

3. Which of the following statements about power adjustment is FALSE?

A) The global radio calibration algorithm includes the Dynamic Channel Allocation (DCA) algorithm and Transmit Power Control (TPC) algorithm.
B) During dynamic power adjustment, it is necessary to select an optimal power to balance the signal coverage with system capacity.
C) A traditional method to control the radio power is to set the transmit power to the maximum value to maximize the radio coverage area. However, a high transmit power may cause interference to other wireless devices.
D) An AP's transmit power determines its radio coverage area. APs with higher power have larger coverage areas.

B) A client fails 802.1x authentication.
C) The test-aaa command is run successfully on the device, but the authentication page cannot be displayed.
D) A correct user name and password are provided, but the system keeps prompting the user to enter a correct user name and password.
