Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 82 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 82
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

An adventure company has launched a new feature on its mobile app. Users can use the feature to upload their hiking and rafting photos and videos anytime. The photos and videos are stored in Amazon S3 Standard storage in an S3 bucket and are served through Amazon CloudFront.

The company needs to optimize the cost of the storage. A solutions architect discovers that most of the uploaded photos and videos are accessed infrequently after 30 days. However, some of the uploaded photos and videos are accessed frequently after 30 days. The solutions architect needs to implement a solution that maintains millisecond retrieval availability of the photos and videos at the lowest possible cost.

Which solution will meet these requirements?

  • A. Configure S3 Intelligent-Tiering on the S3 bucket.
  • B. Configure an S3 Lifecycle policy to transition image objects and video objects from S3 Standard to S3 Glacier Deep Archive after 30 days.
  • C. Replace Amazon S3 with an Amazon Elastic File System (Amazon EFS) file system that is mounted on Amazon EC2 instances.
  • D. Add a Cache-Control: max-age header to the S3 image objects and S3 video objects. Set the header to 30 days.

Selected Answer: A
The correct answer is A. Configure S3 Intelligent-Tiering on the S3 bucket. Amazon S3 Intelligent-Tiering is a storage class that automatically moves objects between two access tiers based on changing access patterns. Objects that are accessed frequently are stored in the frequent access tier and objects that are accessed infrequently are stored in the infrequent access tier. This allows for cost optimization without requiring manual intervention. This makes it an ideal solution for the scenario described, as it can automatically move objects that are infrequently accessed after 30 days to a lower-cost storage tier while still maintaining millisecond retrieval availability.

Option B is not correct as it only moves data to S3 Glacier Deep Archive after 30 days, which would still require additional steps to retrieve the data. Option C is not correct because Amazon Elastic File System (Amazon EFS) is a file storage service for use with Amazon EC2 instances, it does not provide a cost-effective solution for storing and retrieving large amounts of data. Option D is not correct because adding a Cache-Control: max-age header only controls the caching behavior of the objects and does not address the cost optimization requirements.

Option D works for the reduction cost on retrieval request

A is right B S3 Glacier Deep Archive after 30 days is not correct, retrieval takes time so incorrect.

Selected Answer: A
A. Configure S3 Intelligent-Tiering on the S3 bucket: This option would automatically move objects to different storage tiers based on their access patterns. For objects that are infrequently accessed, this would help to reduce storage costs. For those that continue to be accessed frequently, they would remain in a higher-cost but faster-access tier. This should be the option that meets the requirements. B. Configure an S3 Lifecycle policy to transition image and video objects from S3 Standard to S3 Glacier Deep Archive after 30 days: This option would significantly lower storage costs, but the retrieval time for Glacier Deep Archive could take several hours, which does not meet the millisecond retrieval requirement.

Selected Answer: A
B is wrong due to the Glacier Deep Archive part which is not warranted by the question. C is wrong due to the cost of EFS and because it would require some kind of EC2 instance. D would help caching the objects on proxies and clients, but other than that...

Selected Answer: A
I was hesitating between A and D and D looks like a really good option but it's missing one part - we do not do anything with the storage class in this option - we only update the cache TTL which would possibly reduce some costs, however, we keep paying the same price for storage. Hence I switched to A

First half of question drags you to answer B but SA found that some media is being used even after downloads. so data is being accessed in unknown patterns. Way to go is Intelligent tier.

This is my open. The question ask us maintains millisecond retrieval ability. It means we can't use cold storage (So, A, B is not answer). EFS is expensive and not durable. If we use client cache (Ignore client's volume), we can reduce network costs(actually s3's storage costs is really cheap). It means that we can reduce costs too.
