Which benefit describes the capability of a system to recover from unexpected failures?

1. Scalability

2. Resilience

3. Flexibility

4. Performance

The correct answer is: Resilience

The benefit that best describes the capability of a system to recover from unexpected failures is resilience. Resilience refers to the ability of a system to absorb disturbances and continue to function effectively. In the context of IT and cloud environments, resilience ensures that systems can maintain operations despite failures, allowing for minimal downtime and quick recovery. Resilient systems often incorporate redundancy, failover strategies, and backup mechanisms to ensure that in the event of an unexpected disruption—such as hardware failure, network outages, or software issues—the system can restore services swiftly and return to normal operations. This characteristic is crucial for maintaining business continuity and reliability in a cloud environment, where uptime is a critical metric for success. In contrast, scalability relates to a system's ability to handle growth in workload or user demand, flexibility pertains to the system's ability to adapt to changing requirements or setups, and performance focuses on how efficiently a system operates under certain conditions. While these are all important traits for cloud systems, they do not specifically address the system's capability to recover from failures, which is why resilience is the correct choice.
