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

1. Which of following statements about load balancing between the 2.4 GHz and 5 GHz radios are TRUE? (Multiple Choice)

A) When the load difference on the 5 GHz and 2.4 GHz radios is smaller than the load balancing threshold, the AP instructs STAs to preferentially associate with the 5 GHz radio.
B) When the load on the 5 GHz and exceeds the load balancing threshold, the AP instructs STAs to preferentially associate with the 2.4 GHz radio.
C) If the load difference threshold between the two radios is set to 10, the two radios are not load balanced only when there are ten more STAs associated with the 5 GHz radio than with the 2.4 GHz radio.
D) When the load on the 5 GHz exceeds the load balancing threshold, if a STA requests to associate with the 5 GHz radio, the AP will reject the association request until the STA associates with the 2.4 GHz radio.

2. Which of the following methods can implement fast roaming? (Multiple Choice)

A) PMK caching
B) Key negotiation between STA and AP
C) Active STA steering
D) Home agent deployed on the AC

3. Which of the following statements are TRUE about communication between the active/standby ACs with servers in load balancing mode? (Multiple Choice)

A) The IP address of an AC does not need to be configured on the RADIUS/Portal server. The RADIUS/Portal server does not send COA/DM or Portal Logoff packets to the AC.
B) The DHCP server adaptively associates with the relay agent of an AC, but does not automatically send DHCP request packets to the AC.
C) The IP address of an AC needs to be configured on the RADIUS/Portal server. The RADIUS/Portal server sends COA/DM or Portal Logoff packets to the AC.
D) The DHCP server does not adaptively associate with the relay agent of an AC. It automatically sends DHCP request packets to the AC.

4. According to the network, data traffic is transmitted in the STA-HAP-HAC-upper-layer network flow through direct forwarding before roaming, and the home agent is deployed on the AC.
What is the flow direction of data traffic after Layer 3 roaming?

A) STA-FAP-FAC-HAC-upper-layer network
B) STA-FAP-FAC-HAC-HAP-HAC-upper-layer network
C) STA-FAP-FAC-upper-layer network
D) STA-FAP-FAC-HAC-FAC-upper-layer network

5. In a WLAN project, the AC upgrade is interrupted due to a power outage, causing damage to the AC system. In this situation, which of the following method can be used to re-upgrade the AC?

A) CLI-based upgrade
B) Upgrade using the eSight
C) Boot upgrade
D) Web-based upgrade
