In Huawei's smart roaming solution, which of the following methods can be used by a WAC to discover and maintain neighboring AP entries of STAs? (Select All that Apply)
Answer(s): B,C
In Huawei's smart roaming solution, the WAC can discover and maintain neighboring AP entries of STAs by using two methods: passive listening and active scanning. Passive listening means that the AP listens to the Probe frames sent by STAs and reports them to the WAC. Active scanning means that the AP periodically and proactively scans neighboring APs of STAs and reports them to the WAC.

Which of the following statements about the home agent are true? (Select All that Apply)
Answer(s): B,D
The home agent is a device that communicates with the gateway on the STAs' home network at Layer 3 and maintains the binding entries of STAs' home addresses and care-of addresses. A home WAC can function as a home agent of STAs, while a home AP cannot.

Which of the following advantages does BSS coloring provide in Wi-Fi 6? (Select All that Apply)
Answer(s): A,C,D
BSS coloring is a feature introduced in Wi-Fi 6 that assigns different colors to different BSSs to reduce co-channel interference. BSS coloring provides the following advantages:Higher packet rate on the air interface: BSS coloring reduces collisions between packets from different BSSs on the same channel, improving packet transmission efficiency. More efficient channel use: BSS coloring allows spatial reuse of channels by different BSSs, increasing channel utilization.Higher concurrency in high-density scenarios: BSS coloring reduces interference among neighboring APs and improves network performance in high-density scenarios.

An AP may preferentially use the BTM mode to steer some STAs. With which of the following protocols are such STAs compliant?
Answer(s): D
An AP may preferentially use the BTM mode to steer some STAs that are compliant with 802.11v protocol. BTM stands for BSS Transition Management, which is a feature defined in 802.11v protocol that allows an AP to send a request to a STA to switch to another BSS.
