A municipality must keep irreplaceable ordinance PDFs durable and available even if an entire AWS Region becomes unavailable. Which storage reliability strategy best fits?
Select an answer to reveal the explanation.
Short Explanation
One Region’s S3 durability is great until that Region is the problem. Cross-Region Replication puts a second, distant copy of those ordinance PDFs where a regional outage can’t erase them.
Full Explanation
S3 Cross-Region Replication copies objects to another Region to support multi-Region durability and availability goals for irreplaceable content. Single-Region S3 still depends on that Region; EBS on one instance and workstation disks introduce single points of failure unsuitable for ordinance archives. Versioning is commonly paired with CRR to protect against overwrite or delete events. For municipal legal PDFs, CRR is the appropriate replication strategy.
