[Huawei WAN Products and Solutions] Huawei NetEngine AR6710-L14T2X4 supports only the convergence of SD-WAN and switches.

The Huawei NetEngine AR6710-L14T2X4 is a multi-service enterprise router that supports hyper-convergence across multiple functional domains—including routing, switching, SD-WAN, security (firewall, IPS), and network management. It is not limited strictly to the convergence of SD-WAN and switching.

Option A is incorrect because the statement uses the restrictive word "only," which ignores the device's native support for advanced routing protocols, integrated firewall security capabilities, and WAN optimization features alongside SD-WAN and switching functionalities.
