Wireless Mesh Network is a new type of dynamic self-organizing and self-configuring wireless network. The nodes in the network can automatically establish and maintain Mesh connectivity. The nodes of the Mesh link include MPP and MP nodes, which support different functions.
Which of the following functions does MPP have to enable communication between internal nodes of Mesh and external networks?
- A . Automatic route discovery
- B . Automatic Topology
- C . Data message forwarding
- D . Portal function
In Mesh networking, which of the following are necessary conditions for two adjacent APs to establish a Mesh connection? (Multiple choice)
- A . Same security policy
- B . Same Mesh ID
- C . Same channel
- D . The MAC addresses of neighboring APs need to be added to the Mesh whitelist strategy
The current Wi-Fi 6 protocol modulation method already supports 1024 QAM. Compared with 256-QAM, how much is the physical layer link establishment rate increased by 1024-QAM?
- A . 1
- B . 0.5
- C . 0.25
- D . 0.2
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.
A newly deployed WLAN network needs to be optimized at the most basic level. Which of the following aspects can be used to optimize the network? (Multiple choice)
- A . Power
- B . Terminal Migration
- C . Channel
- D . Traffic
As shown in the figure, a company’s WLAN network uses N+1 backup networking. Which of the following descriptions about N+1 backup is wrong?
- A . You can configure the AP’s individual priority on the primary and backup WACs. The larger the priority value, the higher the priority.
- B . All APs under the main WAC1 and main WAC2 must be configured on the backup WAC3 to ensure that the APs can obtain the correct configuration after the WAC is switched.
- C . The backup WAC3 and the primary WAC1 and WAC2 can be deployed in different locations to ensure intercommunication between the three-layer networks.
- D . You can configure the corresponding MAC whitelist on the primary WAC to ensure that the AP can go online on the corresponding WAC to assist the AP in selecting the correct primary WAC.
Which of the following rates is not supported by the 802.11a protocol?
- A . 30Mbps
Which of the following descriptions about HSB is correct? (Multiple choice)
- A . HSB backup can be divided into real-time backup, batch backup, and scheduled backup.
- B . The HSB jumper between the active and standby ACs is used to synchronize AP status, user information, and DHCP address pool information
- C . The default heartbeat period of the HSB channel is 1 ∗ 3s, so the default service interruption time is 3s
- D . HSB heartbeat time and cycle can be modified on AC
In WLAN networks, WLAN roaming optimization technologies such as PMK fast roaming and 802.11r fast roaming are all optimized to shorten roaming time.
- A . True
- B . False
Which of the following descriptions about the roaming experience test function in the CloudCampus app is wrong?
- A . During the test, the terminal needs to associate with the wireless signal and walk in the network coverage area to complete the roaming test.
- B . After the roaming test is completed, the roaming test report will be automatically sent to the customer via email
- C . Ping packets continuously during the test and evaluate the roaming effect by observing packet loss during the roaming process
- D . You can customize the Ping packet address during the roaming test
In WLAN site survey, which of the following statements is correct regarding the need to confirm the AP installation location and related equipment installation in coverage scenarios? (Multiple choice)
- A . If the weak current well is too far from the AP installation location, the switch cannot be installed.
- B . Indoors, you need to confirm the installation location of the AP and the indoor antenna, and the AP installation method, such as wall-mounted, ceiling-mounted, or placed in the ceiling.
- C . Confirm the location of the data center, which is the general gathering point where AC, network management and various servers are usually placed.
- D . Outdoors, you need to confirm the installation location of the AP and outdoor antenna, and whether a pole is needed.
