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 dual-link cold backup, after the AP and the active and standby WAC establish dual links, they will periodically send Echo messages to the active and standby WACs to perform CAPWAP heartbeat detection and check the CAPTAP link status. To speed up the detection of link failures, it is recommended to configure the CAPWAP heartbeat detection interval and number of times as small as possible.
- A . True
- B . False
WLAN air interface is a complex environment, and its performance is related to many factors. In addition to the co-frequency and adjacent-frequency interference between WLAN devices themselves, non-WLAN devices will also interfere with the WLAN air interface performance.
When deploying APs, you should avoid which of the following devices to prevent interference from affecting air interface performance? (Multiple choice)
- A . Wireless game controller
- B . Cordless phone with the same frequency band
- C . Bluetooth devices
- D . Microwave oven
In the WAC high-reliability networking mode, which of the following is correct when sorting the active/standby switching speed from fast to slow?
- A . N+1 backup > VRRP hot backup > dual-link hot backup / dual-link cold backup
- B . VRRP hot backup > dual-link hot backup/dual-link cold backup > N+1 backup
- C . VRRP hot backup > N+1 backup > dual-link hot backup/dual-link cold backup
- D . Dual-link hot backup/dual-link cold backup > VRRP hot backup > N+1 backup
In the WAC high-reliability networking mode, which of the following is correct when sorting the active/standby switching speed from fast to slow?
- A . N+1 backup > VRRP hot backup > dual-link hot backup / dual-link cold backup
- B . VRRP hot backup > dual-link hot backup/dual-link cold backup > N+1 backup
- C . VRRP hot backup > N+1 backup > dual-link hot backup/dual-link cold backup
- D . Dual-link hot backup/dual-link cold backup > VRRP hot backup > N+1 backup
In the WLAN network, among the four transmission systems of SISO, SIMO, MISO and MIMO, only MIMO can transmit two signals at the same time.
- A . True
- B . False
During MAC authentication, to prevent illegal users from brute-forcing the user name and password of the terminal, the silent function of MAC authentication can be enabled. By default, if a user fails to authenticate 5 times within 60 seconds, the access device will discard the user’s authentication request within the next 60 seconds.
- A . True
- B . False
80211r roaming is applicable to many scenarios. The authentication and key negotiation process is omitted during roaming, and the latency is low.
- A . True
- B . False
In a VRRP hot backup scenario, which of the following situations will trigger a master-slave switch? (Multiple choice)
- A . The active WAC itself fails, such as a sudden power outage or hardware failure.
- B . The uplink of the active WAC fails. Based on the VRRP linkage function, the VRRP backup group actively reduces the priority of the active WAC.
- C . The HSB master-slave channel between the master and backup WAC is suddenly disconnected and the connection cannot be established.
- D . The downlink link of the active WAC fails, causing the VLANIF interface bound to the HSB backup group to become Down
In Huawei’s cloud management solution, all APs are managed by the cloud platform. This solution supports roaming between cloud APs at different sites.
- A . True
- B . False
