In the WLAN network cross-WAC roaming scenario, a WAC can only be added to one roaming group at a time, and the WACs in the same roaming group must use the same software VRC version.

• ATrue
• BFalse

• B

Explanation

Option A is correct because in Huawei's WLAN cross-WAC roaming architecture, each WAC (Wireless Access Controller) can belong to only one roaming group at a time - this is a deliberate design constraint that prevents roaming conflicts and ensures predictable handoff behavior between controllers. Additionally, all WACs within the same roaming group must run the same software version (VRC - Version Release Candidate) to guarantee protocol compatibility during inter-controller roaming negotiations; version mismatches would cause roaming failures or inconsistent client experiences.

Option B is wrong because it suggests either constraint is flexible, but both are hard requirements enforced by the WAC software - not configuration options that can be loosened.

Memory tip: Think of a roaming group like a sports league - a team (WAC) can only be in one league at a time, and all teams in that league must play by the same rulebook (same VRC version). Mixed rules = chaos on the court.
