An organization plans to deploy multicast across two different autonomous systems. Their solution must allow RPs to:
*discover active sources outside their domain
*use the underlying routing information for connectivity with other RPs
*announce sources joining the group
Which solution supports these requirements?

The customer solution requires QoS to support streaming multimedia over a WAN. An architect chooses to use Per-Hop Behavior. Which solution should the engineer use to of mark traffic traveling between branch sites?

Refer to the exhibit. EIGRP has been configured on all links. The spoke nodes have been configured as EIGRP stubs, and the WAN links to R3 have higher bandwidth and lower delay than the WAN links to R4.
When a link failure occurs at the R1-R2 link, what happens to traffic on R1 that is destined for a subnet attached to R2?

Which solution allows overlay VNs to communicate with each other in an SD-WAN Architecture?

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?
