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

1. Multiple AD directory servers are used as external source on a large-scale network. Some user information fails to be synchronized to the Agile Controller.
What is the possible cause of the failure? (Multiple Choice)

A) There are no duplicate OU names or user group names on the AD directory servers, but different synchronization types are used to synchronize user information from different AD directory servers.
B) There are duplicate OU names on the AD directory servers, and OU-based synchronization is used.
C) Some user information is manually created on the Agile Controller.
D) The parameter configuration between the Agile Controller and an AD directory server is incorrect.

2. On a WLAN that uses the Agile Controller as the admission control server, which of the following is NOT the cause of 802.1x authentication failures?

A) Port 1813 is used on the server.
B) The matched authorization rule defines the action "deny".
C) The key used by the Agile Controller to connect to the device is different from the key configured on the device.
D) The accounting interval is not configured.

3. 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) 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.
C) 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.
D) 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.

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

A) 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.
B) The second Fresnel zone is surrounded by the first Fresnel zone.
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).

5. On a WLAN network with the WIDS function enabled, APs with the following SSIDs are detected:
a [ssid1]
b [ssid1]
c [ssid1]
d [ssid2]
e [ssid2]
f [ssid1]
MAC addresses of APs b and c are included in the MAC address whitelist. ssid2 is included in the SSID whitelist.
Which of these APs will be identified as rogue APs? (Multiple Choice)

A) a
B) d
C) b
D) f
E) c
