Exam AWS Certified Developer - Associate DVA-C02 topic 1 question 28 discussion

Exam question from Amazon's AWS Certified Developer - Associate DVA-C02
Question #: 28
Topic #: 1
[All AWS Certified Developer - Associate DVA-C02 Questions]

A company hosts a client-side web application for one of its subsidiaries on Amazon S3. The web application can be accessed through Amazon CloudFront from https://www.example.com. After a successful rollout, the company wants to host three more client-side web applications for its remaining subsidiaries on three separate S3 buckets.
To achieve this goal, a developer moves all the common JavaScript files and web fonts to a central S3 bucket that serves the web applications. However, during testing, the developer notices that the browser blocks the JavaScript files and web fonts.
What should the developer do to prevent the browser from blocking the JavaScript files and web fonts?

  • A. Create four access points that allow access to the central S3 bucket. Assign an access point to each web application bucket.
  • B. Create a bucket policy that allows access to the central S3 bucket. Attach the bucket policy to the central S3 bucket
  • C. Create a cross-origin resource sharing (CORS) configuration that allows access to the central S3 bucket. Add the CORS configuration to the central S3 bucket.
  • D. Create a Content-MD5 header that provides a message integrity check for the central S3 bucket. Insert the Content-MD5 header for each web application request.

C This is a frequent trouble. Web applications cannot access the resources in other domains by default, except some exceptions. You must configure CORS on the resources to be accessed. https://docs.aws.amazon.com/AmazonS3/latest/userguide/cors.html

C The question described is a classic case of Cross-Origin Resource Sharing (CORS) where the browser blocks resources (like JavaScript files and web fonts) that are loaded from a different origin (the central S3 bucket) than the web application. To resolve this, a CORS configuration needs to be added to the central S3 bucket to allow these resources to be accessed from the different origins of the web applications.
