Which Mesh Mode Minimizes WLC-Tunneled Traffic?
Short answer
B Flex + Bridge combines FlexConnect local switching with bridge mode to minimize wireless traffic tunneled to the WLC in a mesh network.
Question
Key Takeaways
The question tests whether you know that FlexConnect mode in a mesh network enables local switching, while bridge mode alone tunnels all client traffic to the WLC.
This Cisco 300-425 exam question tests mesh wireless design with bridge mode APs and the goal of minimizing traffic tunneled to the WLC. The correct answer is B (Flex + Bridge), which combines FlexConnect local switching with bridge mode to reduce tunneled traffic.
Common mistake: A common mistake is choosing bridge RAP or bridge MAP, assuming bridge mode alone satisfies the requirements, but bridge mode tunnels all data to the WLC, increasing traffic.
Expert Analysis
Why the Answer Is Correct
Flex + Bridge (option B) is correct because it combines FlexConnect local switching with bridge mode for mesh APs. FlexConnect allows the mesh APs to locally switch client traffic, which directly minimizes the wireless traffic tunneled to the WLC. Bridge mode is the standard mesh bridging operation required by the design. Together, they satisfy all stated requirements: bridge mode APs, WPA2-PSK support, and reduced WLC tunneling.
Why the Other Options Are Wrong
Option A (bridge RAP) and option D (bridge MAP) use bridge mode alone, which tunnels all client data to the WLC and fails the minimization requirement. Option C (FlexConnect) provides local switching but does not explicitly include bridge mode, which the question states must be used. Only Flex + Bridge integrates both features needed for this mesh design.
Community Comment Notes
Community members unanimously agree on B. ShamsDimashki noted that "The data traffic must not go to WLC to reduce traffic" and confirmed B. albiprx, Bembs, and Jonycici also selected Flex + Bridge. No dissenting comments were found, reinforcing the technical analysis.
Exam Strategy
When designing mesh networks, focus on the requirement to minimize traffic tunneled to the WLC. FlexConnect is the key feature that enables local switching; combine it with bridge mode for mesh APs to meet the design constraints.
