A large chain of stores currently uses MPLS-based T1 lines to connect their stores to their data center. An architect must design a new solution to improve availability and reduce costs while keeping these considerations in mind: -The company uses multicast to deliver training to the stores. -The company uses dynamic routing protocols and has implemented QoS. -To simplify deployments, tunnels should be created dynamically on the hub when additional stores open.Which solution should be included in this design?

A. VPLS B. GET VPN C. DMVPN D. IPsec
