AWS Certified Solutions Architect – Professional — Question 107

An AWS customer runs a public blogging website. The site users upload two million blog entries a month. The average blog entry size is 200 KB. The access rate to blog entries drops to negligible 6 months after publication and users rarely access a blog entry 1 year after publication. Additionally, blog entries have a high update rate during the first 3 months following publication, this drops to no updates after 6 months. The customer wants to use CloudFront to improve his user's load times.
Which of the following recommendations would you make to the customer?

Answer options

• A. Duplicate entries into two different buckets and create two separate CloudFront distributions where S3 access is restricted only to Cloud Front identity
• B. Create a CloudFront distribution with ג€US Europeג€ price class for US/Europe users and a different CloudFront distribution with ג€All Edge Locationsג€ for the remaining users.
• C. Create a CloudFront distribution with S3 access restricted only to the CloudFront identity and partition the blog entry's location in S3 according to the month it was uploaded to be used with CloudFront behaviors.
• D. Create a CloudFront distribution with Restrict Viewer Access Forward Query string set to true and minimum TTL of 0.

Correct answer: C

Explanation

The correct answer, C, is appropriate because it allows for better organization of the S3 data based on publication dates, optimizing caching and behavior settings in CloudFront. Option A is incorrect as duplicating data increases costs and management complexity without adding value. Option B does not address the specific needs of access patterns based on the blog entry's lifecycle. Option D is not suitable as it does not enhance caching efficiency for the described access patterns.
