Explanation
Option B is correct because U1900 series unified gateways occupy the core layer (not the access layer) in Huawei's eSpace UC solution, where they handle centralized call processing, media services, and gateway functions for the enterprise. The access layer is instead populated by endpoint devices such as IP phones, softphones, and video terminals that connect users to the network.
Option A is wrong because placing a full-featured unified gateway - which aggregates and processes traffic for the entire solution - at the access layer contradicts its architectural role; access layer devices are lightweight endpoints, not processing hubs.
Memory tip: Think of the "U" in U1900 as Unified/Upward - it sits above the access layer, consolidating and controlling the UC environment from the core, while access-layer devices sit at the edge closest to end users.
