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

1. Which statement about roaming in the same VLAN pool is TRUE?

A) Layer 3 roaming is used for direct forwarding mode.
B) Only Layer 2 roaming is allowed.
C) Only Layer 3 roaming is allowed.
D) Both Layer 2 roaming and Layer 3 roaming are allowed.

2. During global radio calibration, the AC runs () and () algorithms according to the AP neighbor relationship, interference, and load information to generate new transmit power and working channels and delivers them to APs. (Multiple Choice)

A) CAC
B) EDCA
C) TPC
D) DCA

3. To enable STAs to roam between two APs, which of the following conditions must be met? (Multiple Choice)

A) Same security policy
B) Same SSID
C) Same data forwarding mode
D) Same service VLAN

4. Which of the following statements are TRUE about band steering supported by Huawei devices? (Multiple Choice)

A) Load balancing between the 2.4 GHz and 5 GHz radios is considered in band steering. An AP determines the radio with which a STA preferentially associates based on numbers of access users on the 2.4 GHz and 5 GHz radios.
B) If the number of access users on an AP exceeds the start threshold for load balancing between radios, the AP determines the frequency band to which the STA connects based on radio load difference computed according to the formula (Number of access users on the 5 GHz radio - Number of access users on the 2.4 GHz radio/Number of access users on the 5 GHz radio x 100%).
C) After the number of users associated with an AP reaches the start threshold for load balancing between radios, if the value obtained based on the formula (Number of access users on the 5 GHz radio - Number of access users on the 2.4 GHz rad io/N umber of access users on the 5 GHz radio x 100%) is greater than the gap-threshold value, the AP preferentially associates with the STA on the 5 GHz radio.
D) Check whether the number of access users on an AP exceeds the start threshold for load balancing between radios. If not, STAs can preferentially associate with the 5 GHz radio.

5. When configuring the connection between the Agile Controller and WLAN, we need to configure a port number if we want to enable Portal, as shown in the following configuration. The default port number is 2000.
What is the function of this port number?

A) Number of the port that WLAN device uses to process Portal protocol packets
B) Number of the port that the WLAN device uses to receive Portal protocol packets
C) [AC] web-auth-server listening-port 2000
D) Source port number in the packets that the WLAN device sends to the Portal server
E) Destination port number in the packets that the WLAN device sends to the Portal server
