AWS Certified Solutions Architect – Professional — Question 804

Can Provisioned IOPS be used on RDS instances launched in a VPC?

Answer options

• A. Yes, they can be used only with Oracle based instances.
• B. Yes, they can be used for all RDS instances.
• C. No
• D. Yes, they can be used only with MySQL based instances.

Correct answer: B

Explanation

Provisioned IOPS storage is fully supported for all database engines available on Amazon RDS, regardless of whether they are deployed inside a Virtual Private Cloud (VPC). This allows users to meet the high-performance I/O requirements of any supported RDS database engine, such as PostgreSQL, MySQL, MariaDB, Oracle, and SQL Server. Options A and D are incorrect because they limit the feature to specific engines, while Option C is incorrect as VPC deployment does not restrict the use of Provisioned IOPS.
