(Multiple Choice)
A. c
B. d
C. f
D. a
E. b
正解：C,D

質問 2：
Regarding the description of roaming, is the following statement correct?
A. APs that implement wireless roaming must have signal coverage overlap areas
B. APs that implement wireless roaming do not need to have signal coverage overlap areas.
C. APs that implement wireless roaming must be in the same extended service set (ESS)
D. APs that implement wireless roaming must be in the same basic service set (BSS)
正解：A,C

質問 3：
The Agile Controller synchronization method has manual synchronization and automatic synchronization.
Which of the following is true about the synchronization method?
A. The first synchronization of the Agile Controller must be synchronized manually, after which the automatic synchronization can be used.
B. The synchronization time point of the automatic synchronization of the Agile Controller can be modified.
C. Agile Controller manual synchronization can only be used three times a day to prevent artificially increasing network load.
D. The Agile Controller can only use one synchronization mode to avoid mutual interference.
正解：B

質問 4：
After CAC based on channel usage is configured to control user access on an AP, if the current channel usage exceeds the configured threshold, the AP will reject access requests of new STAs and force STAs to log out until the channel usage is lower than the threshold.
A. FALSE
B. TRUE
正解：A

質問 5：
An engineer sets the CAPWAP heartbeat detection interval to 20 seconds and enables dual-link HSB. What is the heartbeat packet transmission timeout interval of the active link before an active/standby switchover occurs?
A. 75 seconds
B. 60 seconds
C. 90 seconds
D. 20 seconds
正解：B

質問 6：
Intelligent roaming, that is, the user is associated with a new AP from the original associated AP. This process is initiated by the user.
A. Correct
B. False
正解：B

質問 7：
As shown in the figure, in the dual-link cold backup load balancing network, as shown in the figure, the two SSIDs of the Huawei and the guest are configured on the AC1, and the SSID of the Huawei is configured on the AC2. The same SSID configuration is the same, and AP1 is online. AC1 and AP1 establish the primary line first. After the AP1 is disconnected from the AC1 link and the active/standby switchover is sent, what is the service status of the user accessed by the Guest SSID?
A. The service in the centralized forwarding mode is uninterrupted, and new users cannot access the Guest.
B. The service is interrupted in the centralized forwarding mode, and new users cannot access the Guest.
C. The service in the local forwarding mode is uninterrupted, and new users cannot access the guest.
D. The service in the local forwarding mode is uninterrupted, and new users can access the guest.
正解：B,C

質問 8：
The following is a description of the mesh networking in the Mesh networking.
A. Can be used in conjunction with Mesh routing to selectively block redundant links to eliminate loops
B. The mesh topology network can detect other LAN devices and form links.
C. Network topology causes network loops
D. In the mesh network, there may be a single point of failure.
正解：A,B,C

質問 9：
Which of the following statements are TRUE about band steering supported by Huawei devices? (Multiple Choice)
A. Load balancing between the 2.4 GHz and 5 GHz radios is considered in band steering. An AP determines the radio with which a STA preferentially associates based on numbers of access users on the 2.4 GHz and 5 GHz radios.
B. Check whether the number of access users on an AP exceeds the start threshold for load balancing between radios. If not, STAs can preferentially associate with the 5 GHz radio.
C. If the number of access users on an AP exceeds the start threshold for load balancing between radios, the AP determines the frequency band to which the STA connects based on radio load difference computed according to the formula (Number of access users on the 5 GHz radio -Number of access users on the 2.4 GHz radio/Number of access users on the 5 GHz radio x 100%).
D. After the number of users associated with an AP reaches the start threshold for load balancing between radios, if the value obtained based on the formula (Number of access users on the 5 GHz radio - Number of access users on the 2.4 GHz radio/Number of access users on the 5 GHz radio x 100%) is greater than the gap-threshold value, the AP preferentially associates with the STA on the 5 GHz radio.
正解：A,B,C
