Huawei HCIP-WLAN CEWA(Huawei Certified ICT Professional-Wireless Local Area Network-Constructing Enterprise WLAN Architecture) Sample Questions:
A company needs to build a large Layer 3 WLAN to cover its office building. There are a large number of employees in the office building and they usually connect to the company WLAN at the entrance and then move to their own work locations.
The company has deployed a wired network and developed a mature wired network management mechanism. The company requires that the newly deployed WLAN be managed and maintained uniformly with the wired network. The IP address of the AC is 172.168.11.1.
Which of the following operations performed by network engineers are CORRECT during WLAN planning? (Multiple Choice)
- A. On a Layer 3 WLAN, set the Option 43 field to 030B3137322E3136382E31312E31 on the Windows 2003 DHCP server.
- B. To facilitate unified wired and wireless network management, adopt the "Chassis switch+ACU2" architecture and configure wired and wireless convergence.
- C. Because the company has a large number of employees and they all connect to the WLAN at the office building entrance, configure VLAN Pool to address the challenge of too many IP address requests in certain areas.
- D. On a large WLAN, an AC manages many APs. To facilitate unified management and maintenance, add APs connected to the AC to the same AP group.
Correct Answer: A,C 🗳️
