AWS Certified Solutions Architect Associate SAA-C03 Practice Question
An online retail corporation requires its e-commerce platform to sustain high availability and resist service disruptions from geographical incidents. The platform is currently experiencing increased customer activity and requires a configuration that mitigates disturbances while preserving transactional integrity in the face of data center outages. What architectural enhancement should be made to reduce the impact of such disruptions on the platform's operation?
Optimize the existing infrastructure within one location with redundant power and networking to ensure uninterrupted service.
Implement a dynamic scaling service to automatically adjust resources in response to changing customer activity.
Extend the platform's presence to multiple geographic locations with data storage replication across these localities.
Arrange for additional standby instances within the current operating area for manual switching during incidences.
Establishing the e-commerce platform across multiple geographical areas, using data storage services capable of replicating information between these areas, is fundamental for mitigating regional failures. This configuration ensures that the platform remains operational and that transactional data is consistent, even if one area experiences a significant outage, hence facilitating continued access and functionality of the platform. Solutions that consider only a single geographical zone or dependent availability zones do not offer protection against broad-area service interruptions. Standby servers within the same zone, while useful for localized failures, do not cover broad-area disruptions, and scaling services typically address capacity rather than regional availability concerns.
