Question

Quizplus · Accepted Answer

Fault tolerance at the disk level refers to the ability of a storage device to maintain data availability in the event of a component failure. On the other hand, fault tolerance at the server level refers to the ability of a server to maintain availability in the event of a hardware or software failure, which may include failures of multiple components. These two types of fault tolerance are different, as they apply to different levels of the IT infrastructure.
