H12-311_V3.0 · Question #190
For areas with roaming requirements, the coverage of adjacent APs should maintain an overlap of more than 50%, so as to ensure the smooth switching of terminals between APs.
The correct answer is B. False. Option B (False) is correct because the recommended coverage overlap between adjacent APs in roaming areas is typically 15–20%, not more than 50%. A 15–20% overlap provides sufficient signal continuity for terminals to detect and associate with the next AP before losing…

Explanation
Option B (False) is correct because the recommended coverage overlap between adjacent APs in roaming areas is typically 15–20%, not more than 50%. A 15–20% overlap provides sufficient signal continuity for terminals to detect and associate with the next AP before losing connection with the current one.
Option A is wrong because a >50% overlap is excessive - it would cause severe co-channel interference between adjacent APs sharing the same channel, degrading throughput and overall network performance rather than improving roaming.
Memory tip: Think of it like highway lane merges - you only need a short overlap zone (15–20%) to smoothly transition, not half the road. "Fifty is too many" - more overlap means more interference, not smoother roaming.
