In the N+1 backup networking shown in the figure, the global priority of AC3 is set to 5, and the global priorities of AC1 and AC2 are set to 6. The API-specific priority of AC1 is set to 3, and the AP3-specific priority of AC2 is set to 3. When no AP connects to AC1, AC2, and AC3, which AC will API, AP2, AP3, and AP4 connect to respectively?

• A.API connects to AC3, AP2 connects to AC1 or AC2, AP3 connects to AC3, and AP4 connects to AC3.
• B.API connects to AC1, AP2 connects to AC3, AP3 connects to AC2, and AP4 connects to AC3.
• C.API connects to AC3, AP2 connects to AC3, AP3 connects to AC3, and AP4 connects to AC1 or AC2.
• D.API connects to AC1, AP2 connects to AC1 or AC2, AP3 connects to AC2, and AP4 connects to AC1 or AC2.

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

In the dual-link cold standby load balancing networking shown in the figure, two SSIDs Huawei and Guest are configured on AC1, and the SSID Huawei is configured on AC2. The two ACs have the same SSID Huawei configuration. API has gone online and set up the primary CAPWAP tunnel with AC1. When the primary CAPWAP tunnel between API and AC1 is disconnected and an active/standby switchover occurs, what is the service status of users connected to the SSID Guest? (Multiple Choice)

• A.In local forwarding mode, service transmission remains uninterrupted and new users can connect to the SSID Guest.
• B.In local forwarding mode, service transmission remains uninterrupted, but new users cannot connect to the SSID Guest.
• C.In centralized forwarding mode, service transmission remains uninterrupted, but new users cannot connect to the SSID Guest.
• D.In centralized forwarding mode, service transmission is interrupted and new users cannot connect to the SSID Guest.

In smart roaming, to determine whether a neighbor AP with better signals exists, an 802.11k-incapable STA needs to start scanning to obtain neighbor AP information.

• A.TRUE
• B.FALSE

Which of the following statements about active neighbor probe is FALSE?

• A.Active probe is used to establish neighbor relationships between authorized APs.
• B.Active probe is used to obtain the maximum interference signal strength between authorized neighboring APs, in which signal strength of the neighboring AP is the key.
• C.Active probe and passive probe are used to collect interference information from rogue APs.
• D.An AP periodically sends Probe Request frames destined for a specified multicast address on different channels. After receiving the frames, surrounding APs learn that the AP is a neighbor.
