A company is using flaws Database Migration Service (flaws DMS) to replicate data from a source database in a data center to a target Amazon Aurora PostgreSQL database. The company has created a DMS replication task with change data capture (CDC).
The replication instance sometimes gets interrupted and affects critical functionality. The company must improve the replication instance's resiliency and receive notifications about interruptions.
Which solution will meet these requirements with the LEAST operational overhead?

A. Copy data from the source database to Amazon S3 by using flaws DataSync. Configure flaws Lambda functions to copy the data to the target database. Configure Amazon CloudWatch alarms to monitor the Lambda functions for errors and throttles. Use an Amazon Simple Notification Service (Amazon SNS) topic for email notification.

B. Create Amazon CloudWatch alarms to monitor DMS replication task metrics and host metrics. Use an Amazon Simple Notification Service (Amazon SNS) topic for email notification and to invoke an flaws Lambda function to configure a standby DMS replication instance in a different flaws Region.

C. Create Amazon CloudWatch alarms to monitor DMS replication task metrics and host metrics. Use an Amazon Simple Notification Service (Amazon SNS) topic for email notification. After receiving the notification, configure a new DMS replication task in the same flaws Region.

D. Modify the DMS replication instance by tuming on Multi-AZ support. Create Amazon CloudWatch alarms to monitor DMS replication task metrics and host metrics. Use an Amazon Simple Notification Service (Amazon SNS) topic for email notification.
