What should I do if I lose the Network Connection between the two Sites?

I have a customer who asked me what happens when his MPLS goes down. I told him that he would have the most recent replication that has happened is what he would have to work with. since he will be running an active passive model to a hosted data center he just needs to make sure that the replication of the Protected VM's is happening at a manageable RPO for the business.

I guess the real question I have is around the DNS. he said the public DNS is also on the MPLS or WAN. So what would he need to do to protect that in the event of a fail over?

What does he mean that the public DNS is on the MPLS or WAN? Are they talking about the link between their sites going down or all connectivity to a site (eg both to other sites and the internet)?

Either way, this is going to be a whole lot of "it depends". What are they trying to accomplish?
