AWS Certified Solutions Architect – Associate (SAA-C03) — Question 375

A company is planning to migrate a commercial off-the-shelf application from its on-premises data center to AWS. The software has a software licensing model using sockets and cores with predictable capacity and uptime requirements. The company wants to use its existing licenses, which were purchased earlier this year.

Which Amazon EC2 pricing option is the MOST cost-effective?

Answer options

• A. Dedicated Reserved Hosts
• B. Dedicated On-Demand Hosts
• C. Dedicated Reserved Instances
• D. Dedicated On-Demand Instances

Correct answer: A

Explanation

Dedicated Hosts are required to support Bring Your Own License (BYOL) scenarios that depend on physical sockets and cores, which rules out Dedicated Instances. Because the application has predictable capacity and uptime requirements, opting for Reserved pricing instead of On-Demand pricing ensures the most cost-effective solution.
