Huawei HCIP-WLAN CEWA(Huawei Certified ICT Professional-Wireless Local Area Network-Constructing Enterprise WLAN Architecture) Sample Questions:
1. Which statement about the Mesh whitelist is TRUE?
A) The system can automatically create whitelist.
B) The whitelist can control topology and prevent unauthorized devices from accessing the Mesh network.
C) The whitelist can prevent access of unauthorized users.
D) The whitelist can replace the WPA.
2. Which of the following packets does an AP working in monitor mode use to determine device types?
A) CAPWAP
B) 802.11 MAC
C) DHCP
D) ARP
3. In Layer 3 roaming, STAs roam from one AP to another AP, and the service VLANs of the corresponding VAPs change. After roaming, data packets of the STAs are sent to the service VLAN of the AP to which STAs roam.
A) TRUE
B) FALSE
4. Which of the following statements are TRUE about the application scenarios and features of the ACs? (Multiple Choice)
A) The independent AC such as the AC6605 applies to scenarios which require unified construction of wired and wireless networks and unified management on wired and wireless users.
B) The native AC such as the X1E card provides higher forwarding performance than the independent AC, such as the AC6605. In addition, the native AC can implement link and device redundancy, making the WLAN more reliable.
C) The native AC such as the X1E card applies to scenarios where the wired and wireless users are managed separately.
D) The AC card such as ACU2 applies to large-scale networks and scenarios which have insufficient rack space but require capacity expansion.
5. Which of the following statements about power adjustment is FALSE?
A) A traditional method to control the radio power is to set the transmit power to the maximum value to maximize the radio coverage area. However, a high transmit power may cause interference to other wireless devices.
B) The global radio calibration algorithm includes the Dynamic Channel Allocation (DCA) algorithm and Transmit Power Control (TPC) algorithm.
C) During dynamic power adjustment, it is necessary to select an optimal power to balance the signal coverage with system capacity.
D) An AP's transmit power determines its radio coverage area. APs with higher power have larger coverage areas.
