A customer requests that you design their Layer 3 VPN solution so that all site-to-site traffic goes through a central site, in a hub-and-spoke fashion You must choose between using one or two interfaces on the hub WAN link.
In this scenario, which solution would you use?

Exhibit.

You are asked to design a solution that will provision a circuit from the corporate headquarters to a remote branch. The circuit must be secure, and must support IGP adjacencies. IPsec has been chosen to secure traffic across the WAN connection.
Referring to the exhibit which statement describes another requirement for this circuit to function correctly?

Your customer is deploying a data center with redundant connections for WAN services through ISP-1 and ISP-2. Your customer has decided to deploy an active/passive Internet connection uplink model and pay-per-use for a passive connection associated with ISP-2. The customer wants to ensure limited use of the connection through ISP-2.
Which two actions would you perform to meet the objective? (Choose two )

You are asked to create a point-to-multipoint DCI that does not overwhelm the data plane with MAC learning traffic.
Which protocol would you use in this situation?

You want to migrate your network from using Draft-Rosen to multicast VPN, Due to functional similarities, it will help operations personnel make the transition if they are familiar with certain technologies In this scenario, which technology would be helpful?
