A. Sidelobe

B. Signal reflection

C. Harmonic signal

D. Sideband

A. Authentication using a digital certificate

B. MAC address bypass authentication

C. Authentication using a common account

D. Third-party authentication

A. The AP and ACs set up the primary and backup tunnels at the same time and complete configuration delivery.

B. The AP sends a Join Request message, notifying the standby AC that the configurations have been delivered.

C. After receiving the Join Request message, the AC sets up a CAPWAP tunnel with the AP but does not deliver configurations to the AP.

D. The AP sends a Discovery Request message to the standby AC in broadcast mode.

A. Active probe is used to establish neighbor relationships between authorized APs.

B. Active probe and passive probe are used to collect interference information from rogue APs.

C. 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.

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.

A. Sizes of Disassociation and Deauthentication frames

B. Source addresses of Disassociation and Deauthentication frames

C. Number of Disassociation and Deauthentication frames

D. Destination addresses of Disassociation and Deauthentication frames

A. The AP accesses the virtual address of the active or standby AC.

B. The AP accesses the physical address of the active AC.

C. The AP accesses the physical address of the standby AC.

D. The AP accesses any address configured on the AC.

A. None of them

B. AC1

C. AC2

D. Either of them

A. FALSE

B. TRUE

A. FALSE

B. TRUE

A. When configuring dual-link HSB, you need to run the commit command on the active AC to deliver the configuration to APs after completing service configurations on the active AC. Then perform configurations on the standby AC.

B. When configuring dual-link HSB, you need to run the commit command on the active AC to deliver the configuration to APs after completing service configurations on both the active and standby ACs.

C. During an active/standby switchover between two ACs, services forwarded through the tunnel may be interrupted because the switchover takes a long time. New users cannot go online and online users cannot roam between APs.

D. When configuring dual-link HSB, ensure that active and standby ACs deliver the same WLAN service configuration to an AP. If the configurations are inconsistent, the AP may not work properly after an active/standby switchover between ACs.

A. FALSE

B. TRUE

A. 1. The MP periodically broadcasts PREQ. 2. The MPs/MPPs receiving the PREQ reply with unicast PREP. 3. The route and return route are established between two points.

B. 1. The MPP periodically broadcasts RANN. 2. The MP receiving the RANN sends a unicast PREQ to the MPP. 3. The MPP replies with a PREP. 4. The route is established between MP and MPP.

C. 1. The MPP periodically broadcasts PREQ. 2. The MP receiving the PREQ sends a unicast PREP to the MPP. 3. The route is established between MP and MPP.

D. 1. The MPP periodically broadcasts RANN. 2. The MP receiving the RANN sends a unicast PREP to the MPP. 3. The route is established between MP and MPP.

A. User information

B. OU information

C. Information of the domain where the OU is located

D. User group information
