AWS Certified Solutions Architect – Associate (SAA-C03) — Question 572

A company's SAP application has a backend SQL Server database in an on-premises environment. The company wants to migrate its on-premises application and database server to AWS. The company needs an instance type that meets the high demands of its SAP database. On-premises performance data shows that both the SAP application and the database have high memory utilization.

Which solution will meet these requirements?

Answer options

• A. Use the compute optimized instance family for the application. Use the memory optimized instance family for the database.
• B. Use the storage optimized instance family for both the application and the database.
• C. Use the memory optimized instance family for both the application and the database.
• D. Use the high performance computing (HPC) optimized instance family for the application. Use the memory optimized instance family for the database.

Correct answer: C

Explanation

Since both the SAP application and the SQL Server database exhibit high memory utilization in the on-premises performance metrics, selecting memory optimized EC2 instances for both tiers is the most appropriate solution. Compute optimized, storage optimized, and HPC optimized instances do not prioritize RAM to the degree required by these memory-intensive workloads. Therefore, using memory optimized instances for both components ensures optimal performance and stability post-migration.
