AWS Certified Cloud Practitioner (CLF-C02) — Question 601

A company has applications that control on-premises factory equipment.

Which AWS service should the company use to run these applications with the LEAST latency?

Answer options

• A. AWS Outposts
• B. Amazon EC2
• C. AWS Lambda
• D. AWS Fargate

Correct answer: A

Explanation

AWS Outposts allows organizations to run AWS infrastructure and services locally within their own physical facilities, delivering the single-digit millisecond latency required to communicate with on-premises machinery. In contrast, standard Amazon EC2, AWS Lambda, and AWS Fargate run in remote AWS Regions, which introduces higher network latency that could disrupt real-time equipment control.
