Question

You are evaluating assets and come across a server that must be operational 99.99 percent of the time. what would you use to achieve this?

Answer 1

A failover cluster would be most useful in this situation. This would allow the server to have a backup (or failover) that could take action when the main server(s) stop functioning or need to be taken down for a time. This gives the security of knowing that there will always be at least one server in the cluster that is operational.
