A company stores data in an on-premises Oracle relational database. The company needs to make the data available in Amazon Aurora PostgreSQL for analysis. The company uses an AWS Site-to-Site VPN connection to connect its on-premises network to AWS.

The company must capture the changes that occur to the source database during the migration to Aurora PostgreSQL.

Which solution will meet these requirements?

A. Use the AWS Schema Conversion Tool (AWS SCT) to convert the Oracle schema to Aurora PostgreSQL schema. Use the AWS Database Migration Service (AWS DMS) full-load migration task to migrate the data.
B. Use AWS DataSync to migrate the data to an Amazon S3 bucket. Import the S3 data to Aurora PostgreSQL by using the Aurora PostgreSQL aws_s3 extension.
C. Use the AWS Schema Conversion Tool (AWS SCT) to convert the Oracle schema to Aurora PostgreSQL schema. Use AWS Database Migration Service (AWS DMS) to migrate the existing data and replicate the ongoing changes.
D. Use an AWS Snowball device to migrate the data to an Amazon S3 bucket. Import the S3 data to Aurora PostgreSQL by using the Aurora PostgreSQL aws_s3 extension.

Which combination of steps will meet these requirements? (Choose two.)

A. Replace the EC2 instance with a larger compute optimized instance.
B. Configure Amazon EC2 Auto Scaling with multiple Availability Zones in private subnets.
C. Configure a NAT gateway in a public subnet to handle web requests.
D. Replace the EC2 instance with a larger memory optimized instance.
E. Configure an Application Load Balancer in a public subnet to distribute web traffic.

A company's marketing data is uploaded from multiple sources to an Amazon S3 bucket. A series of data preparation jobs aggregate the data for reporting. The data preparation jobs need to run at regular intervals in parallel. A few jobs need to run in a specific order later.

The company wants to remove the operational overhead of job error handling, retry logic, and state management.

Which solution will meet these requirements?

A. Use an AWS Lambda function to process the data as soon as the data is uploaded to the S3 bucket. Invoke other Lambda functions at regularly scheduled intervals.
B. Use Amazon Athena to process the data. Use Amazon EventBridge Scheduler to invoke Athena on a regular internal.
C. Use AWS Glue DataBrew to process the data. Use an AWS Step Functions state machine to run the DataBrew data preparation jobs.
D. Use AWS Data Pipeline to process the data. Schedule Data Pipeline to process the data once at midnight.

A company maintains its accounting records in a custom application that runs on Amazon EC2 instances. The company needs to migrate the data to an AWS managed service for development and maintenance of the application data. The solution must require minimal operational support and provide immutable, cryptographically verifiable logs of data changes.

Which solution will meet these requirements MOST cost-effectively?

A. Copy the records from the application into an Amazon Redshift cluster.
B. Copy the records from the application into an Amazon Neptune cluster.
C. Copy the records from the application into an Amazon Timestream database.
