Exam 350-101 Topic 5 Question 44 Discussion

Bridge mode in a Cisco wireless mesh deployment allows access points to operate as mesh infrastructure nodes, typically as a Root AP (RAP) or Mesh AP (MAP), so Ethernet segments can be connected across a wireless backhaul. Cisco's mesh design documentation states that in a point-to-point bridging scenario, a mesh AP can extend a remote network by using the backhaul radio "to bridge two segments of a switched network." This directly maps to option A: point-to-point communication between network segments.
In Catalyst 9800 mesh deployments, Cisco documents converting an AP to bridge mode withcapwap ap mode bridge, after which the AP rejoins the controller in bridge mode and can be assigned a mesh role. Cisco also defines the RAP as the AP with the wired connection toward the WLC, while the MAP joins through its radio path toward the RAP. Option B is incorrect because bridge mode does not force all traffic to 2.4 GHz; Cisco mesh backhaul can use configured backhaul radios. Option C describes RRM/TPC behavior, not bridge mode.
Option D incorrectly associates mesh bridge mode with WAN edge functions. Reference topics:Wireless Network Implementation - mesh AP roles, RAP/MAP operation, wireless backhaul, and Ethernet bridging.
