We'll cover the following

Question 19

An organization wants to share regular updates about their charitable work using static web pages. The pages are expected to generate a large number of views from around the world. The files are stored in an Amazon S3 bucket.

Which action should the solutions architect take to accomplish this?

  1. Generate pre-signed URLs for the files.
  2. Use Cross-Region Replication to all Regions.
  3. Use the geoproximity feature of Amazon Route 53.
  4. Use Amazon CloudFront with the S3 bucket as its origin.

Correct Answer: 4

Explanation: Using Amazon CloudFront to cache the files in edge locations around the world will improve the performance of the webpages.

To serve a static website hosted on Amazon S3, you can deploy a CloudFront distribution using one of these configurations:

  • Using a REST API endpoint as the origin with access restricted by an origin access identity (OAI)
  • Using a website endpoint as the origin with anonymous (public) access allowed
  • Using a website endpoint as the origin with access restricted by a Referer header

INCORRECT: “Generate presigned URLs for the files.” is incorrect as this is used to restrict access, which is not a requirement.

INCORRECT: “Use Cross-Region Replication to all Regions.” is incorrect as this does not provide a mechanism for directing users to the closest copy of the static web pages.

INCORRECT: “Use the geoproximity feature of Amazon Route 53.” is incorrect as this does not include a solution for having multiple copies of the data in different geographic locations.

CORRECT: “Use Amazon CloudFront with the S3 bucket as its origin.” is the correct answer.
