H19-401_V2.0 Exam Dumps : HCSP-Presales-Campus Network Planning and Design V2.0

iStack (Intelligent Stack) is a horizontal virtualization technology used primarily at the access and aggregation layers of the campus network. It allows multiple physical switches to be connected via stack cables and managed as a single logical device with a unified management IP and configuration file. This eliminates the need for complex protocols like STP (Spanning Tree Protocol) to prevent loops, as the links between the stack and the upstream devices are treated as a single inter-device Eth-Trunk.

Global radio calibration is a process where the WAC or iMaster NCE calculates the optimal channel and power levels for all APs. It is not a "the more, the better" task. Frequent or immediate calibration during peak hours can cause "flapping," where APs constantly change channels, leading to service interruptions and client disconnections. Huawei recommends performing global calibration during off-peak hours (e.g., at night) or using AI-based calibration (CampusInsight) which makes gradual, intelligent adjustments rather than disruptive immediate changes.

The NetEngine AR5710-S8T1XWE is a high-performance converged gateway designed for small and medium branches. According to the technical specifications for the AR5710-S series, the built-in WAC (Wireless Access Controller) capability allows for the management of up to 64 APs (with an initial free license for 32 APs). This hyper-converged design allows a single device to handle routing, switching, security, and wireless management, which is a key recommendation for "Simplified Branch" scenarios in the V2.0 guide.
