AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A financial services firm has applications that are crucial for its day-to-day operations. This firm cannot afford a downtime of more than 2 hours and must ensure data is not lost beyond a 5-minute interval in case of a system failure. The current deployment spans across several fault-tolerant zones within a single region. Which disaster recovery approach should be recommended to meet the firm's stringent continuity needs?
Formulating an active-active topology distributed over several geographical regions with traffic management to control workload distribution.
Periodic data backups to a durable storage service with cross-region replication capabilities, allowing for restoration in a different geographic area if needed.
Adopting a strategy where crucial parts of the system are always ready to be activated in a geographically separate region.
Arranging a scaled-down, on-demand version of the application stack in another region, which can be brought online in response to disruptions.
