Answer: Creating Read Replica's

## Explanation **Read Replicas** in Amazon RDS allow you to offload read traffic from your primary database instance to one or more read-only copies of your database. This feature provides several benefits: - **Improved Performance**: Read-heavy database workloads can be distributed across multiple replicas - **Scalability**: You can scale out beyond the capacity constraints of a single database instance for read-heavy workloads - **Availability**: Read replicas can serve read traffic even if the primary instance becomes unavailable - **Geographic Distribution**: Read replicas can be created in different AWS regions for low-latency reads **Why the other options are incorrect:** - **A. Cross region replication**: While cross-region replication can be used with Read Replicas, it's not specifically designed for offloading reads - **C. Using snapshots**: Snapshots are for backup and restore purposes, not for offloading read traffic - **D. Using Multi-AZ feature**: Multi-AZ provides high availability and automatic failover for the primary database, but doesn't offload read traffic Read Replicas are specifically designed to handle read scaling by allowing applications to direct read queries to replica instances while write operations go to the primary instance.
