In a WLAN network, if the VLAN IDs of two subnets are different, the roaming of the terminal between the two subnets is considered as Layer 3 roaming.
- A . True
- B . False
When the engineer was inspecting the customer’s wireless network, he found that the terminal failed to access the wireless network.
The possible reasons for the terminal online failure are checked through the CampusInsight protocol playback function. The terminal protocol playback is shown in the figure. Which option is wrong in the description of the terminal online failure? 
- A . Repair suggestion: Try to ping the authentication server to check whether the physical link of the authentication server is connected.
- B . Repair suggestion: Check whether the RADIUS server template configuration parameters are consistent with the actual configuration on the RADIUS server.
- C . The terminal has obtained an IP address through DHCP, but a failure occurs during the subsequent authentication phase
- D . The most likely cause of the terminal going online failure is that the RADIUS server is unreachable.
In a certain enterprise office WLAN network, network engineers found that many APs were offline for a long time after being disconnected, or were offline again after being online.
Which of the following could be the cause of this failure?
- A . The AP’s peer device has SIP enabled, but the AP has not.
- B . The AP is not assigned an IP address
- C . Insufficient license resources
- D . WAC does not support this AP type
Which of the following functions can WLAN Planner achieve? (Multiple choice)
- A . On-site signal scanning
- B . 3D simulation
- C . Automatic deployment of APs
- D . View the field strength simulation diagram
In the WLAN network, WLAN security provides a variety of security strategies, such as OPEN, WEP, WPA and WPA2, and each security strategy embodies a complete set of security mechanisms.
of the following security strategies has the strongest encryption?
- A . WPA3
- B . WEP
- C . WPA2
- D . WPA
Which of the following descriptions about the differences between Layer 2 roaming and Layer 3 roaming are correct? (Multiple choice)
- A . If the VLAN IDs of two subnets are the same, STA roaming between the two subnets is considered Layer 2 roaming.
- B . Layer 3 roaming means that the client roams between different subnets
- C . If the VLAN IDs of the two subnets are different, STA roaming between the two subnets is considered Layer 3 roaming.
- D . Layer 2 roaming means that the client roams between the same subnets
In VRRP hot standby networking, which of the following descriptions of VRRP protocol configuration are correct? (Multiple choice)
- A . The default interval for sending VRRP protocol heartbeat messages is 1 second
- B . The default priority of the VRRP protocol is 100. The WAC with a smaller priority value will become the primary WAC
- C . The vrid of the VRRP protocol in the primary and backup WACs must be configured consistently
- D . The virtual IP address of the VRRP protocol in the primary and backup WAC must be configured―
Multicast messages are sent at a low rate on the air interface. A large number of such messages will occupy a large amount of air interface resources, affecting the transmission of normal user service data packets. In scenarios without multicast services, when the service data forwarding method adopts tunnel forwarding, it is recommended to configure multicast message suppression on WAC.
Which of the following configuration commands for the multicast packet suppression function is correct?
- A . [WAC-wlan-view] rrm-profile name test
[WAC – wlan-rm-prof-test] traffic-optimize multicast-suppression packets 1000 - B . WAC-wlan-view] traffic-profile name test
[WAC-wlan-traffic-prof-test] traffic-optimize broadcast-suppression packets 1000 - C . [WAC-wlan-view] traffic-profile name test
[WAC-wlan-traffic-prof-test] traffic-optimize multicast-suppression packets 1000 - D . WAC-wlan-view] rrm-profile name test
[WAC – wlan-rrm-prof-test] traffic-optimize broadcast-suppression packets 1000
When planning a WLAN network in a hotel scenario, since hotels have high requirements for aesthetics: therefore, when engineers select AP models and design wiring plans, they must communicate with customers in advance and confirm the feasibility of the plan.
- A . True
- B . False
In Huawei’s intelligent roaming solution, for terminals that support 802.11k, when the AP determines that the terminal is a sticky terminal, it will actively trigger the terminal to perform neighbor measurement based on the 802.11k mechanism. Which of the following information will be collected during the 11k neighbor measurement process? (Multiple choice)
- A . AP signal strength
- B . AP power
- C . BSSID of the AP
- D . AP’s working channel
