AWS Certified Solutions Architect – Associate (SAA-C03) — Question 187

A company has a Microsoft .NET application that runs on an on-premises Windows Server. The application stores data by using an Oracle Database Standard Edition server. The company is planning a migration to AWS and wants to minimize development changes while moving the application. The AWS application environment should be highly available.

Which combination of actions should the company take to meet these requirements? (Choose two.)

Answer options

• A. Refactor the application as serverless with AWS Lambda functions running .NET Core.
• B. Rehost the application in AWS Elastic Beanstalk with the .NET platform in a Multi-AZ deployment.
• C. Replatform the application to run on Amazon EC2 with the Amazon Linux Amazon Machine Image (AMI).
• D. Use AWS Database Migration Service (AWS DMS) to migrate from the Oracle database to Amazon DynamoDB in a Multi-AZ deployment.
• E. Use AWS Database Migration Service (AWS DMS) to migrate from the Oracle database to Oracle on Amazon RDS in a Multi-AZ deployment.

Correct answer: B, E

Explanation

Option B is correct because rehosting the application on AWS Elastic Beanstalk with a Multi-AZ deployment ensures high availability with minimal changes. Option E is correct as it allows the Oracle database to be migrated to Oracle on Amazon RDS, which supports Multi-AZ deployments for enhanced availability. Options A, C, and D involve significant changes or do not align with the requirement for high availability.
