Which of the following features of RDS allows for data redundancy across regions?
A
Cross region replication
B
Creating Read Replica's
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
