• B.(a) (d) (b) (c)
• C.(a) (b) (d) (c)
• D.(b) (a) (d) (c)

Which is the correct procedure of Mesh link establishment?

• A.② -> ④ -> ③ -> ①
• B.④ -> ③ -> ② -> ①
• C.② -> ③ -> ④ -> ①
• D.④ -> ② -> ③ -> ①

Which of the following statements are TRUE about band steering supported by Huawei devices? (Multiple Choice)

• A.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.
• B.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%).
• C.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.
• 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.

Which of the following statements about the three backup modes are TRUE? (Multiple Choice)

• A.Dual-link HSB: backs up AP, STA, and CAPWAP link information.
• B.No matter in hot standby or cold standby mode, a standby AC can provide backup services for only one active AC.
• C.VRRP HSB: backs up AP, STA, and CAPWAP link information.
• D.Dual-link backup is a cold backup mode, which does not back up STA information. An AP sets up a link with both the active and standby ACs. During an active/standby switchover or a revertive switchover, STAs need to go online again and services are temporarily interrupted.

Which of the following commands is used to check whether automatic channel selection and automatic transmit power selection are enabled for APs?

• A.[AC-wlan-view] display radio all
• B.[AC-wlan-view] display station ssid wlan-net
• C.[AC-wlan-view] display vap-profile name profile-name
• D.[AC-wlan-view] display rrm-profile name profile-name
