A system designed for operational continuity despite system degradation is known as what?

1. Scalable System

2. Efficient System

3. Fault Tolerant System

4. Redundant System

The correct answer is: Fault Tolerant System

A system designed for operational continuity despite system degradation is referred to as a Fault Tolerant System. Fault tolerance refers to the ability of a system to continue functioning correctly even in the presence of faults or failures. This is accomplished through hardware or software mechanisms that allow for the detection and isolation of faults, enabling other components of the system to take over and maintain operation without interruption. In the context of cloud computing and IT infrastructure, fault tolerance is crucial because it ensures high availability and reliability. For example, if a server experiences a hardware failure, a fault-tolerant system might switch to a backup server or redistribute the workload among remaining servers, allowing services to continue without noticeable downtime. The other options, while they may contribute to system performance or availability, do not specifically describe the characteristic of continuing operation in the face of system degradation. A scalable system focuses on the ability to increase capacity, an efficient system emphasizes optimal use of resources, and a redundant system offers backups for failover but does not inherently provide the mechanisms for dynamic recovery and continuous operation like a fault tolerant system does.
