Topic #: 1

[All AWS Certified Developer - Associate DVA-C02 Questions]

A developer is creating a publicly accessible enterprise website consisting of only static assets. The developer is hosting the website in Amazon S3 and serving the website to users through an Amazon CloudFront distribution. The users of this application must not be able to access the application content directly from an S3 bucket. All content must be served through the Amazon CloudFront distribution.

Which solution will meet these requirements?

A. Create a new origin access control (OAC) in CloudFront. Configure the CloudFront distribution's origin to use the new OAC. Update the S3 bucket policy to allow CloudFront OAC with read and write access to access Amazon S3 as the origin.
B. Update the S3 bucket settings. Enable the block all public access setting in Amazon S3. Configure the CloudFront distribution's with Amazon S3 as the origin. Update the S3 bucket policy to allow CloudFront write access.
C. Update the S3 bucket's static website settings. Enable static website hosting and specifying index and error documents. Update the CloudFront origin to use the S3 bucket's website endpoint.
D. Update the CloudFront distribution's origin to send a custom header. Update the S3 bucket policy with a condition by using the aws:RequestTag/tag-key key. Configure the tag-key as the custom header name, and the value being matched is the header's value.

changing to A. Origin access identity is now considered a legacy solution. The official AWS documentation now recommends that Origin Access Control is used instead.

Selected Answer: C

We don't want to provide write access to CloudFront since it's a static website. S3 should suffice

Option C requires public access to the bucket to be allowed. "The users of this application must not be able to access the application content directly from an S3 bucket. All content must be served through the Amazon CloudFront distribution." OAC allows us to turn this feature off and still access the bucket contents via cloudfront.

Selected Answer: A

While enabling the block all public access setting in Amazon S3 is a good security practice and necessary for this scenario, simply allowing CloudFront "write access" is not relevant since the scenario involves serving static assets, not writing to the S3 bucket. This option also doesn't specify using an OAC or a similar method to ensure exclusive access through CloudFront.
