Exam H12-811_V2.0 Topic 1 Question 53 Discussion

This statement is false . In Layer 3 in-path WLAN networking , the WAC and Fit APs communicate over Layer 3, which means the APs must discover the WAC through methods that are valid across Layer 3 boundaries. Broadcast is a Layer 2 mechanism and cannot normally be used for WAC discovery across Layer
3 networks. Therefore, saying that APs can obtain the WAC address through broadcast or DHCP in this scenario is incorrect.
In Huawei WLAN deployments, Fit APs can commonly discover the WAC address through methods such as DHCP option-based discovery , DNS , or preconfigured controller information, depending on the deployment model and product features. Because the WAC and AP are not in the same Layer 2 broadcast domain in Layer 3 in-path networking, broadcast discovery is not the standard mechanism here. HCIA- Datacom stresses the difference between Layer 2 direct discovery and Layer 3 discovery methods because this affects initial AP registration, CAPWAP establishment, and troubleshooting when APs fail to go online.
Understanding the discovery mechanism is essential when planning IP addressing, DHCP options, and controller placement in enterprise WLAN designs.
