As shown in the figure, in a dual-link load balancing hot backup network, AP1 is a newly online AP, and both ACs have access configurations, which AC will AP1 choose for access?
- A . AC1
- B . AC2
- C . Random access
- D . No access
In a WLAN network, the AP group is named ap-group and the WIDS template is wids. Now you need to enable the WIDS device counter function to counter APs with counterfeit SSID=huawei. As shown in the figure, which of the following configuration is correct?
- A . 1>2>4
- B . 5>2>3
- C . 1>2>3
- D . 5>2>4
The following figure shows the mesh configuration process. What should be filled in for 5, 7, and 10 respectively?
- A . Quote Mesh template, configure Mesh whitelist, configure Mesh template
- B . Configure Mesh whitelist, configure Mesh template, quote Mesh template
- C . Configure Mesh template, quote Mesh template, configure Mesh whitelist
- D . Configure Mesh whitelist, quote Mesh template, configure Mesh template
As shown in the figure, regarding the active/standby mode of the dual-system hot backup solution, which of the following statements is wrong?
- A . VRRP can be applied to active/standby backup and load sharing
- B . The selection of dual-system hot backup master and backup devices is consistent with the selection of VRRP group master and backup devices
- C . The active/standby status of the HSB active/standby backup group is consistent with the VRRP active/standby status
- D . For the same AP associated with the active and standby ACs, the WLAN-related service configuration must be consistent. Otherwise, the normal operation of the AP cannot be guaranteed after the AC’s active and standby status is switched
If a small conference room with a maximum of 90 people is equipped with 3 APs, by configuring CAC on each AP, the number of users cannot exceed 30, and the SSID will be hidden after exceeding, which can indirectly achieve the effect of load balancing among APs.
- A . True
- B . False
Regarding the precautions for configuring HSB main and backup services, which of the following statements is wrong?
- A . If you want to modify, you need to delete the HSB active and standby services first, and then reconfigure
- B . Only after enabling the dual-system hot backup function, the configured HSB active/standby backup channel parameters will take effect
- C . After the configuration is complete, you can modify the HSB main and backup channel parameters
- D . After the configuration is complete, you cannot directly modify the HSB main and backup channel parameters
Regarding the relationship between the two technologies of 802.1x and RADIU S, which of the following descriptions is correct?
- A . 802.1x and RADIUS are different names of the same technology
- B . 802.1x is a technical system, which includes RADIUS
- C . 802.1x and RADIUS are different technologies, but they are often used together to complete the access control of end users.
- D . 802.1x and RADIUS are two completely different technologies, and they are usually not used together
In the WLAN outdoor long-distance point-to-point communication, if a stable communication link is to be maintained, what percentage of the first Fresnel area generally cannot be blocked?
- A . 0.2
- B . 0.4
- C . 0.5
- D . 0.6
In the load balancing mode, which of the following regarding the statement about the processing method of hot backup by RADIUS/Portal server is correct?
- A . Account and authenty the NAS-IP-Address and accounting session-id filled in the backup packet
- B . The srcip in the Radius packet sent by the AC needs to be the same, and the COA/DM device address configured in the Radius server can be different from one to the other
- C . In the case of DOWN/uplink interruption of the original master node, the COA/DM message received by the node needs to be processed and synchronized to the opposite end, and the master device needs to issue authorization information to the AP
- D . When the original master node, not the whole machine down/uplink is interrupted, the backup node also configures a Loopback interface with the same IP as the master node. This interface is not directly added to the IGP, but imported through import direct
In smart roaming, which of the following methods to identify sticky terminals is correct?
- A . When the results of 3 consecutive detection cycles are less than the set roaming threshold
- B . When the results of 3 consecutive detection cycles are greater than the set roaming threshold
- C . When the results of 6 consecutive detection cycles are less than the set roaming threshold
- D . When the results of 6 consecutive detection cycles are greater than the set roaming threshold
