Which of the following terms refers to the ability to recover from faults in a system?

The concept of high availability refers to a system's ability to remain operational and accessible even in the face of faults or failures. High availability aims to minimize downtime by implementing redundancy and failover mechanisms, ensuring that critical services remain available to users. This is crucial in cloud environments where uptime is essential for business operations and customer trust.

High availability strategies often involve configurations that can detect failure and reroute traffic or tasks to alternative resources without significant delay. This can include maintaining multiple instances of a service or equipped systems that can take over if one fails. Therefore, the ability to quickly recover from faults is a fundamental characteristic of high availability.

Scalability addresses how well a system can grow and manage increased workloads, disaster recovery focuses on processes and policies that enable data recovery after catastrophic events, and load balancing distributes workloads across resources to ensure no single resource is overwhelmed. While all these concepts are important in cloud security and systems management, high availability specifically pertains to fault recovery and service continuity.
