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

Question 1

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

Question 2

In the dual-link cold standby load balancing networking shown in the figure, two SSIDs Huawei and Guest are configured on AC1, and the SSID Huawei is configured on AC2. The two ACs have the same SSID Huawei configuration. AP1 has gone online and set up the primary CAPWAP tunnel with AC1.

When the primary CAPWAP tunnel between AP1 and AC1 is disconnected and an active/standby switchover occurs, what is the service status of users connected to the SSID Guest? (Multiple Choice)

A. In local forwarding mode, service transmission remains uninterrupted, but new users cannot connect to the SSID Guest.
B. In centralized forwarding mode, service transmission is interrupted and new users cannot connect to the SSID Guest.
C. In local forwarding mode, service transmission remains uninterrupted and new users can connect to the SSID Guest.
D. In centralized forwarding mode, service transmission remains uninterrupted, but new users cannot connect to the SSID Guest.

Question 3

Which of the following statements about the active CAPWAP link setup procedure are TRUE? (Multiple Choice)

A. In Discovery phase, after dual-link backup is enabled, an AP broadcasts a Discovery Request packet.

C. If the AC priorities are the same, the AP compares the loads of the ACs, that is, the number of APs. The AP selects the AC connecting to fewer APs as the active AC.
