Which solution should be included in this design?

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.
