AWS Technical Essentials 2025 – 400 Free Practice Questions to Pass the Exam

The primary function of Amazon EC2 (Elastic Compute Cloud) is to provide resizable compute capacity in the cloud. This service enables users to quickly scale their computing resources up or down as needed, which is essential for handling varying workloads and application demands. With EC2, users can launch virtual servers, known as instances, that run applications and services, thus fulfilling the need for flexible and scalable computing power.

This flexibility allows organizations to deploy applications without the upfront investment in hardware, facilitate testing and development processes, and manage production workloads efficiently. The pay-as-you-go pricing model further enhances this capability, as users only pay for the compute capacity they use.

Other options, while they pertain to cloud services, do not accurately capture the primary function of EC2. For example, storing data securely is more aligned with services like Amazon S3, which is specifically designed for object storage. Managing user permissions relates to AWS IAM (Identity and Access Management), which is focused on access management rather than computing capacity. Finally, distributing web content is typically handled by Amazon CloudFront, a content delivery service that helps improve the delivery of content and applications to end-users.
