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

1. An AP working in monitor mode can forward WLAN data while monitoring neighboring devices.

A) TRUE
B) FALSE

2. Which of the following packets does an AP working in monitor mode use to determine device types?

A) ARP
B) CAPWAP
C) DHCP
D) 802.11 MAC

3. The zone surrounding the line of sight (LOS) is called the Fresnel zone, which is also called the RF LOS.

A) TRUE
B) FALSE

4. 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) An AP's transmit power determines its radio coverage area. APs with higher power have larger coverage areas.
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) During dynamic power adjustment, it is necessary to select an optimal power to balance the signal coverage with system capacity.

5. Which of the following statements about the second Fresnel zone are TRUE? (Multiple Choice)

A) The second Fresnel zone is surrounded by the first Fresnel zone.
B) If the RF signal and primary signal have the same frequency and different phases and the two signals intersect, the RF signal weakens or even offsets the primary signal. Because reflection is one of the factors causing interference to the primary signal, impact of the second Fresnel zone on signals must be considered during evaluation of point-to-point communication links.
C) If signals in the second Fresnel zone are reflected to the receive end due to the antenna height and terrain, the link quality may degrade.
D) Impact of the second Fresnel zone should be considered during network planning and troubleshooting, especially in flat and dry environments (such as deserts).
