A
Using Multi-AZ feature
B
Using Read Replica feature
C
Using Database Migration Service
D
Using AWS Backup
Explanation:
The correct answer is B - Using Read Replica feature.
Explanation:
-
Read Replica feature allows you to create read-only copies of your database instance in the same AWS Region or in different AWS Regions. Cross-region read replicas enable you to replicate data to another region for disaster recovery or to serve read traffic from locations closer to your users.
-
Multi-AZ feature (Option A) provides high availability within a single AWS Region by maintaining a synchronous standby replica in a different Availability Zone, but it does not replicate data to another region.
-
Database Migration Service (Option C) is used for migrating databases to AWS, not for ongoing replication.
-
AWS Backup (Option D) is for backup and recovery purposes, not for real-time data replication.
