SAP-C02 Question #211: Real Exam Question with Answer & Explanation

Question

A company is migrating an on-premises content management system (CMS) to AWS Fargate. The company uses the CMS for blog posts that include text, images, and videos. The company has observed that traffic to blog posts drops by more than 80% after the posts are more than 30 days old. The CMS runs on multiple VMs and stores application state on disk. This application state is shared across all instances across multiple Availability Zones Images and other media are stored on a separate NFS file share. The company needs to reduce the costs of the existing solution while minimizing the impact on performance. Which combination of steps will meet these requirements MOST cost-effectively? (Choose two.)

Options

• AStore media in an Amazon S3 Standard bucket. Create an S3 Lifecycle configuration that
• BStore media on an Amazon Elastic File System (Amazon EFS) volume Attach the EFS volume to
• CStore application state on an Amazon Elastic File System (Amazon EFS) volume. Attach the EFS
• DStore application state on an Amazon Elastic Block Store (Amazon EBS) volume. Attach the EBS
• EStore media in an Amazon S3 Standard bucket. Create an S3 Lifecycle configuration that

Explanation

To cost-effectively migrate an on-premises CMS with shared application state and NFS media to AWS Fargate, while accommodating declining traffic for older posts, scalable and shared storage solutions are needed.

Common mistakes.

• B. Storing media on an Amazon Elastic File System (EFS) volume is generally more expensive than Amazon S3 for large amounts of static content, especially when S3 lifecycle policies can be used to optimize costs for infrequently accessed media.
• D. Amazon EBS volumes are block storage, which are typically attached to a single EC2 instance in a specific Availability Zone and are not directly shareable across multiple Fargate tasks or instances in different AZs for shared application state.
• E. This option is identical to A, indicating a potential issue with the question's choices, but A is designated as part of the correct answer.

Concept tested. Cost-effective storage solutions for CMS components (static media, shared application state) on AWS Fargate
