QUESTION 1
In Layer 3 roaming, STAs roam from one AP to another AP, and the service VLANs of the corresponding VAPs change.
After roaming, data packets of the STAs are sent to the service VLAN of the AP to which STAs roam.

A. TRUE
B. FALSE

Answer: B

QUESTION 2
Which of the following statements about precautions for HSB configuration is FALSE?

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 both the active and standby ACs.
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 the active AC. Then perform configurations on the standby AC.
C. 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.
D. 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.

Answer: B

QUESTION 3
In the figure, transparent transmission of STP packets may cause mutual impact between bops. To prevent the impact, which statement about STP is TRUE?

B. STP needs to be enabled on only MP3’s wired interfaces.
C. STP needs to be enabled on the wired interfaces of both MPP and MP3.
D. STP needs to be enabled on MP1 and MP2.

Answer: C
