質問 2:Which statement about the Mesh profile is FALSE?
A. An STA will not modify its Mesh profile unless the profile is deleted from the BSS (the STA is a member of the BSS).
B. All STAs in a Mesh BSS have the same Mesh profile. If two Mesh profiles have the same parameters, the profiles are considered the same.
C. After a Mesh BSS is set up or an STA joins a BSS, the STA generates a Mesh profile.

質問 3: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 rad io/N umber 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

B. Layer 2 roaming indicates that STAs roam within the same subnet.
C. After Layer 3 roaming is performed, the VLAN IDs in the service set of APs are changed.
D. Layer 3 roaming indicates that STAs roam between different subnets.
正解:B,C,D

B. ① > ② > ③
C. ① > ② > ④
D. ⑤ > ② > ③
