A startup company wants to launch an online learning portal on AWS using CloudFront and S3. They have different subscription models. One model where all the members will have access to basic content but another model where the company provides premium content that includes access to multiple private contents without changing their current links.
How should a Solution Architect design this solution to meet the requirements?

Answer options:

A.Design the learning portal using CloudFront web distribution to deliver the premium private content using Signed Cookies.
B.Design the learning portal using CloudFront web distribution to deliver the premium private content using Signed URLs.
C.Design the learning portal using CloudFront web distribution to deliver the premium private content using S3 pre-signed URLs.
D.Design the learning portal using CloudFront web distribution to deliver the premium private content using CloudFront signed URLs.

Answer: A
Option A is CORRECT. Use signed cookies in the following cases to provide access to multiple restricted files. For example, all the files for a video in HLS format or all of the files in the subscribers` area of the website. You don`t want to change your current URLs.
Option B is incorrect.CloudFront signed URLs and signed cookies provide the same basic functionality, and they allow users to control who can access the content.
Use signed URLs in the following cases.
· You want to restrict access to individual files, for example, an installation download for your application-
· Your users are using a client (for example, a custom HTTP client) that doesn`t support cookies.
Option C is incorrect because S3 pre-signed URLs won’t provide access without changing current links.
Option D is incorrect because CloudFront UTLS won’t provide access without changing current links.
