A company wants its applications to remain available during a regional outage. Which cloud characteristic should it prioritize?

Fault tolerance is the correct answer because it refers to the ability of a system to continue operating even if one or more components fail. In the context of a regional outage, a fault-tolerant architecture would involve deploying applications across multiple availability zones or regions, ensuring that if one region experiences an outage, the application remains accessible from another. Multi-cloud strategy involves using multiple cloud providers, which can contribute to resilience but isn't the primary characteristic for remaining available during a single regional outage within one cloud provider. Cost management focuses on optimizing expenses, not directly on availability during an outage. DevOps integration is about combining development and operations practices to shorten the development lifecycle, which doesn't directly address outage resilience.
