Explanation:
Explanation:
-
Cross region replication (Option A) is the correct answer because it specifically enables data redundancy across different AWS regions. This feature creates a replica of your RDS database in a different AWS region, providing disaster recovery capabilities and geographic redundancy.
-
Creating Read Replicas (Option B) typically operates within the same region or across Availability Zones within the same region, but does not inherently provide cross-region redundancy. While you can create cross-region read replicas, this is a specific configuration that falls under cross-region replication capabilities.
Cross-region replication in RDS provides:
-
Disaster recovery capabilities
-
Geographic data distribution
-
Compliance with data residency requirements
-
Reduced latency for global applications
-
Enhanced data durability across multiple geographic locations
