Deploying an application across multiple Availability Zones within a single AWS Region provides which benefit?

Deploying an application across multiple Availability Zones (AZs) within a single AWS Region is a core strategy for building a resilient and highly available architecture. Each AZ is an isolated location within a region, designed to be independent of failures in other AZs. If one AZ experiences an outage (e.g., power failure, network disruption), the application can continue to run in the other AZs, minimizing downtime and ensuring continuous operation. Improved connection performance for global customers is incorrect because AZs are within a single region; for global performance, you'd use multiple regions or services like Amazon CloudFront. Reduced overall data storage costs is incorrect; multi-AZ deployments might increase storage costs due to replication. Ability to shut down an Availability Zone during periods of low demand is incorrect; AZs are infrastructure components, not designed to be shut down by users for cost savings.
