Answer: AWS Business Support

## Explanation AWS Business Support is the **least expensive** AWS Support plan that provides a **full set of AWS Trusted Advisor best practice checks**. Here's why: ### AWS Support Plans Comparison: - **AWS Basic Support**: - Free tier - Only provides **7 core Trusted Advisor checks** - Does **NOT** include the full set of best practice checks - **AWS Developer Support**: - Paid plan - Still only provides **7 core Trusted Advisor checks** - Does **NOT** include the full set of best practice checks - **AWS Business Support**: - Paid plan - Provides **full set of AWS Trusted Advisor best practice checks** - **Least expensive** option that includes all Trusted Advisor features - **AWS Enterprise Support**: - Most expensive plan - Provides full set of AWS Trusted Advisor best practice checks - Includes additional premium features ### Key Point: While both AWS Business Support and AWS Enterprise Support provide the full set of Trusted Advisor checks, **AWS Business Support** is the **least expensive** option that offers this feature. The Basic and Developer Support plans only include limited core checks, not the complete best practice analysis. This makes AWS Business Support the correct answer as the most cost-effective way to access comprehensive Trusted Advisor functionality.
