A county property database needs automated failover across Availability Zones; multi-Region DR is optional for cost reasons. Which recommendation fits?
Select an answer to reveal the explanation.
Short Explanation
Multi-AZ is the building’s sprinkler and backup generator on the same campus. Multi-Region is a second courthouse in another city—you buy it when the business pays for that RTO. Don’t skip Multi-AZ, and don’t force three-Region active-active when they only asked for AZ resilience.
Full Explanation
Multi-AZ database deployments provide synchronous standby failover within a Region for infrastructure failures, meeting high availability without requiring multi-Region complexity. Multi-Region DR addresses Region-level disasters and is a separate cost and RTO decision. Single-AZ with only manual restores fails the automated cross-AZ requirement, forcing unused active-active Regions ignores the optional cost constraint, and Multi-AZ does not replace backups or imply cross-Region copies. Align HA with Multi-AZ and keep multi-Region optional per business need.
