Answer explanation

A context clue is given in the question itself that helps identify which term best describes the concept the company wants, “They want to ensure that their servers are running even in the event that a single Data Center goes down".

Fault Tolerance is a concept in IT in which a computer system or set of infrastructure is designed in such a way that when one component fails (be it hardware , software, or network) a backup component takes over operations immediately so that there is no loss of service. So if the company hosted servers at two Data Centers, even if one Data Center went down the other Data Center would "turn on" and continue running those servers without any loss in service.
