QUESTION 73
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?

QUESTION 74
An engineer must design a solution to provide backup connectivity between two sites. The engineer plans to use an Internet connection but company policy requires the connection to be encrypted. Additionally, there are several applications that utilize multicast to deliver video streams between the sites. Which technology should the design include?

QUESTION 75
