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

Question 1

Which of the following statements about global calibration algorithms are TRUE? (Multiple Choice)

A. The core of the Dynamic Channel Allocation (DCA) algorithm is the exhaustion and iteration algorithms, which list all possible AP-Channel combinations and choose the optimal combination.
B. If the interference caused by a neighbor is smaller than the lower interference threshold, the algorithm determines whether to reduce the transmit power according to the difference between the interference caused by the neighbor and the lower interference threshold.
C. The Transmit Power Control (TPC) algorithm aims to choose a proper transmit power which can meet coverage requirements of an AP.
D. Interference specified by the lower interference threshold is low, and within the allowed range. Two neighbor APs cannot detect interference from each other and can send packets simultaneously.

Question 2

Which of the following statements is TRUE about the Agile Controller admission control model? (Multiple Choice)

A. The authorization elements do not include the IP address range.
B. Currently, only 802.1x and Portal authentication support all conditions in the admission control model.
C. The core of the model is the authorization condition and authorization result.
D. Authorization conditions include authorization elements.

Question 3

Which of the following processing methods are TRUE, to solve the packet congestion on the tunnel? (Multiple Choice)

A. The HAC discards broadcast or multicast ARP, ND, DHCP, and mDNS packets to prevent loops.
B. The FAP discards unknown unicast packets and forwards other packets to roaming STAs.
C. After broadcast/multicast packets are transparently transmitted to the FAC, the FAC converts the packets to unicast packets and forwards the packets over a specific tunnel based on the home AP connected to it.
D. The HAC at the tunnel ingress discards unknown unicast packets.

Question 4

On a WLAN that uses the Agile Controller to implement admission control, which of the following statements are TRUE about the pre-authentication domain? (Multiple Choice)

A. The method of configuring the pre-authentication domain is the same as that of configuring the post-authentication domain.
B. If ACLs are used for the pre-authentication domain, user ACLs need to be used.
C. IP addresses of the following devices need to be permitted in the pre-authentication domain: anti-virus gateway, firewall, and mail server.
D. There are two ways to configure the pre-authentication domain: by using ACLs, or by adding authentication-free rules.

Question 5

In a scenario that uses the Agile Controller to implement admission control, which of the following statements is TRUE about the roles of the RADIUS server/client?

A. The Agile Controller functions as the RADIUS server, while the user terminal functions as the RADIUS client.
B. The Agile Controller integrates all functions of the RADIUS server and client.
C. The authentication device (for example, 802.1x-enabled switch) functions as the RADIUS server, while the user terminal functions as the RADIUS client.
D. The Agile Controller functions as the RADIUS server, while the authentication device functions as the RADIUS client.
