AWS Certified Database – Specialty — Question 252

A company runs an ecommerce application on premises on Microsoft SQL Server. The company is planning to migrate the application to the AWS Cloud. The application code contains complex T-SQL queries and stored procedures.

The company wants to minimize database server maintenance and operating costs after the migration is completed. The company also wants to minimize the need to rewrite code as part of the migration effort.

Which solution will meet these requirements?

Answer options

• A. Migrate the database to Amazon Aurora PostgreSQL. Turn on Babelfish.
• B. Migrate the database to Amazon S3. Use Amazon Redshift Spectrum for query processing.
• C. Migrate the database to Amazon RDS for SQL Server. Turn on Kerberos authentication.
• D. Migrate the database to an Amazon EMR cluster that includes multiple primary nodes.

Correct answer: C

Explanation

The correct answer is C because migrating to Amazon RDS for SQL Server allows the company to maintain compatibility with their existing T-SQL code, minimizing the need for extensive code rewrites. Options A and B involve different database systems that would require significant changes to the application code, while option D does not align with the need for minimizing maintenance and costs.
