In a WLAN network, there are five steps in the basic process of network planning. Please sort the following steps according to the workflow.
Which of the following statements about the principles of WLAN outdoor site deployment is correct? (Multiple choice)
- A . The site should be directly visible to the coverage area, and it is recommended that there should be no obstacles blocking the view.
- B . To ensure signal transmission, the site should be installed as high as possible
- C . Avoid strong electric and magnetic fields and other signal interference near the site
- D . There needs to be a reliable power supply near the site
In the Portal authentication scenario, if there is no condition to deploy an external independent Portal server, the built-in Portal server of WAC can be used for authentication. Which of the following descriptions about the built-in Portal server is wrong?
- A . Due to compatibility issues with some mobile browsers, Portal authentication users using these browsers will not be able to complete authentication.
- B . The built-in Portal server does not support MAC-first Portal authentication
- C . The built-in Portal server does not support custom authentication page content and style
- D . Compared with the external Portal server, the built-in Portal server has simple functions and limited performance and is only suitable for scenarios with a small number of access users.
With the development of Wi-Fi technology, WLAN network has become one of the main means of enterprise network access, and users have higher requirements for the experience of WLAN network. In order to meet the user experience requirements, engineers need to continuously maintain and optimize the WLAN network.
Usually, engineers optimize WLAN networks from which of the following aspects? (Multiple choice)
- A . Client Optimization
- B . Network optimization
- C . Wired network optimization
- D . Wireless beam optimization
A retail store has newly built a WLAN network. For the in-store barcode scanner business, users require multiple barcode scanners to connect to the same SSID, but each barcode scanner needs to be configured with a different key, and there is no need to deploy an authentication server. Which of the following authentication methods can engineers use to meet the above requirements?
- A . WPA/WPA2-DPSK authentication
- B . WPA/WPA2-PPSK authentication
- C . Static WEP authentication
- D . WPA/WPA2-802.1X authentication
During the demand collection phase of WLAN network planning, three types of information need to be obtained: basic requirements, business requirements, and installation requirements.
Which of the following information is not included in the business requirements?
- A . Power distribution method
- B . Field strength requirements
- C . Terminal Type
- D . Coverage area
During the acceptance of the customer’s wireless network, the engineer found that the terminal roaming failed. Which of the following situations may be the cause of the terminal roaming failure? (Multiple choice)
- A . The customer’s existing network is a Layer 3 roaming scenario, but the device is configured to prohibit Layer 3 roaming
- B . AP signal coverage is discontinuous and there are blind spots
- C . The user forwarding methods configured on the two roaming APs are inconsistent
- D . The security template names configured on the two roaming APs are inconsistent
In a WLAN network, when engineers configure the DHCP server, they need to pay attention to whether the WAC and the AP are in the same network segment. If they are in the same network segment, the DHCP server does not need to configure the option 148 field and the AP can also discover the WAC by broadcasting. If the WAC and the AP are not in the same network segment, the DHCP server must configure the option 148 field to specify the IP address of the WAC for the AP, otherwise the AP will not be able to discover the WAC.
- A . True
- B . False

Which of the following descriptions of AC deployment methods is correct? (Multiple choice)
- A . AC deployment can be divided into two types: side-mounted deployment and direct-connected deployment.
- B . Side-mounted networking is an existing network overlay method, which requires less modification to the existing network and is quick and convenient to deploy. In addition, direct forwarding or tunnel forwarding mode can be selected according to the control requirements for wireless users.
- C . In the direct connection deployment mode, because the AC is connected in series in the network, the management data and user data between the AP and AC must be forwarded through the CAPWAP tunnel.
- D . Direct connection is mainly used in large campus network scenarios. The recommended number of APs in the network is more than 1,000.
