Explanation

The primary goal of fault tolerance is to ensure that a system can continue operating smoothly despite the failure of one or more of its components. This is primarily achieved by eliminating single points of failure (SPOF). A single point of failure refers to any component or system whose failure would cause the entire system to stop functioning. Fault tolerance involves designing systems so that, if one component fails, others can take over the workload without disrupting the operation of the system. Fault tolerance mechanisms typically include: Redundancy (e.g., having backup power supplies, multiple servers, or database replicas). Failover mechanisms to automatically switch to a backup when a failure occurs. By addressing SPOFs, systems can remain available, resilient, and operational even when some
