Global users read and write the same user profile in their nearby Regions.
Continue operating in another Region if one Region fails.
Choose TWO appropriate components.
Use DynamoDB Global Tables with regional replicas and connect each application to its local replica.
Detailed explanation
Local replicas reduce latency and improve continuity during a regional failure.

Foundation review
Locality
Connecting users to a nearby replica reduces network latency.
Regional resilience
A second replica provides a place to continue when one Region is unavailable.
