Explanation

IP MPLS is preferred over VRF-Lite for WAN connectivity primarily because of OpEx (Operational Expenditure) savings. With VRF-Lite, the enterprise must manually maintain separate routing tables and VRF configurations on every router along the WAN path, which increases operational complexity and cost. With MPLS, the service provider handles the Layer 3 VPN infrastructure, reducing the burden on enterprise network engineers. Load balancing (A) and reliability (B) can be achieved with both approaches, so they are not the distinguishing preference factors.
