APs in monitoring mode in the WLAN network can not only monitor peripheral devices but also forward WLAN data.
- A . True
- B . False
In the Mesh network, if the MP is connected to the wired network, it is necessary to ensure that the MP and MPP cannot communicate with each other through the wired network. Otherwise, the MPP and MP can communicate with each other through the Mesh link and the wired link. Mesh and wired The link will form a loop between MPP and MP.
- A . True
- B . False
When the air interface frame is a data frame, the DS value needs to be compared. When the values of To DS and From DS are respectively, the device type is AP?
- A . 0, 0
- B . 0, 1
- C . 1, 0
- D . 1, 0
There are three implementations of CAC. Which of the following statements about the implementation of CAC based on channel utilization is wrong?
- A . When the AP receives a new user online request, it first calculates the channel utilization rate on the current radio, and if the new user threshold is not reached, the new user is allowed to go online
- B . If the channel utilization reaches the new user threshold after the new user goes online, the access request of other new users is rejected and an alarm is sent, but the SSID cannot be hidden
- C . For the access of roaming users, check whether the channel utilization rate has reached the roaming user threshold. If it reaches, then reject the roaming user’s access request and send an alarm
- D . The AP periodically checks the channel utilization of the radio frequency, and once it drops below the threshold for new users, it sends a release alarm to allow new users to go online
Which of the following descriptions about Mesh routing establishment in pro-active mode is correct?
- A . MP periodically sends broadcast PREQ, receives MP/MPP response unicast PREP, and establishes a round-trip route between any two points
- B . MPP sends broadcast RANN periodically, receives MP and sends unicast PREQ to MPP, MPP responds to PREP after receiving it, and establishes a route between MP and MPP
- C . MPP periodically sends broadcast RANN, receives MP and sends unicast PREP to MPP, and establishes a route between MP and MPP
- D . MPP periodically sends broadcast PREQ, the received MP responds to unicast PREP, and establishes a route between MP and MPP
In the WLAN network, the Weak IV attack detection function does not require the support of the dynamic blacklist function.
- A . True
- B . False
The antenna is different from the signal amplifier. It is a passive device that does not require power supply, but only guides and shapes the wireless signal.
- A . True
- B . False
Regarding enabling the HSB backup group, if the AP is already online on the main AC, and then the AP information is added offline on the standby AC, the AP status on the standby AC will display fault. In this case, you need to execute the undo hsb enable command in the HSB backup group view of the standby AC to enable the HSB active/standby backup function, and then execute the hsb enable command to enable the HSB active/standby backup function, and then back up the information on the active AC again. The backup information of the active and standby is consistent, and the AP status on the standby AC will be displayed as standby at this time.
- A . True
- B . False
In a large-scale WLAN network, in order to improve the reliability of the C APWAP link between AP and AC, the DSCP priority of CAPWAP management messages can be configured as high priority.
- A . True
- B . False
Which of the following commands can be used to check whether the AP channel and transmit power are enabled with the automatic selection function?
- A . [AC-wlan-view] display station ssid wlan-net
- B . [AC-wlan-view] display rrm-profile name profile-name
- C . [AC-wlan-view] display radio all
- D . [AC-wlan-view] display yap-profile name profile-name
