Guide to Fault Tolerance

Fault Tolerance is an important concept in the area of business continuity and disaster recovery. This concept is essential because it ensures that a system continues to function even in the event of partial system failure.
What is Fault Tolerance?
Fault Tolerance refers to the ability of a system to continue its operations, possibly at a reduced level, rather than failing completely, when some part of the system fails.
How does Fault Tolerance work?
Fault Tolerance works through a combination of redundant hardware and software. This redundancy allows a system to continue to operate even when a component fails. For instance, a server may have multiple hard drives so that if one fails, others can take over.
Exam Tips: Answering Questions on Fault Tolerance
1. Understand the key concepts: The main idea behind fault tolerance is continued system operation despite partial system failure. This should form the basis of your answers.
2. Know examples of fault-tolerant systems: Being able to describe situations where fault-tolerant systems are used can help illustrate your understanding of the concept.
3. Focus on redundancy elements: Exam questions often focus on how redundancy is used to achieve fault tolerance. Be ready to discuss these points in detail.
Remember that a clear understanding of the key concept and well-organised presentation of your knowledge can help you do well in exam questions on Fault Tolerance.

Fault Tolerance practice test

Fault Tolerance refers to the ability of a system, component, or infrastructure to continue functioning without interruption even when one or more of its parts fail. The goal of fault tolerance is to minimize the risk of system downtime, data loss, and other negative impacts on business operations. Fault tolerance can be achieved through various approaches, such as redundancy, load balancing, and failover systems that can take over the failed components. Implementing fault-tolerant systems will involve additional costs. However, it is important for organizations to weigh these costs against the potential losses that could result from system failures and interrupted operations, especially for mission-critical systems.
