Question #: 651
Topic #: 1

[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company stores a large volume of image files in an Amazon S3 bucket. The images need to be readily available for the first 180 days. The images are infrequently accessed for the next 180 days. After 360 days, the images need to be archived but must be available instantly upon request. After 5 years, only auditors can access the images. The auditors must be able to retrieve the images within 12 hours. The images cannot be lost during this process.

A developer will use S3 Standard storage for the first 180 days. The developer needs to configure an S3 Lifecycle rule.

Which solution will meet these requirements MOST cost-effectively?

A. Transition the objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) after 180 days. S3 Glacier Instant Retrieval after 360 days, and S3 Glacier Deep Archive after 5 years.
B. Transition the objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) after 180 days. S3 Glacier Flexible Retrieval after 360 days, and S3 Glacier Deep Archive after 5 years.
C. Transition the objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 180 days, S3 Glacier Instant Retrieval after 360 days, and S3 Glacier Deep Archive after 5 years.
D. Transition the objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 180 days, S3 Glacier Flexible Retrieval after 360 days, and S3 Glacier Deep Archive after 5 years.

Selected Answer: C

Images cannot be lost = high availability. Transition the objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 180 days, S3 Glacier Instant Retrieval after 360 days, and S3 Glacier Deep Archive after 5 years.

Yes but flexible retrieval is lower in cost than instant retrieval while meeting the SLA of 12 hours for retrieval. Answer is D

"The developer needs to configure an S3 Lifecycle rule."--->One Zone-IA can't transfer to Glacier Instant Retrieval--->A is out. Check - Unsupported lifecycle transitions https://docs.aws.amazon.com/AmazonS3/latest/userguide/lifecycle-transition-general-considerations.html "Images cannot be lost = high availability"--->Can't be One Zone-IA--->B is out. "the images need to be archived but must be available instantly upon request"--->Can't be "Flexible" Retrieval--->D is out. Only C is the correct answer.

Selected Answer: A

A. Here's why this option is the most cost-effective: +S3 One Zone-IA (after 180 days): Offers lower storage costs compared to S3 Standard for infrequently accessed data (180 - 360 days) while maintaining good availability for retrieval. +S3 Glacier Instant Retrieval (after 360 days): Provides immediate access to archived images (360 - 5 years) at a significantly lower cost than S3 Standard storage. Retrieval costs are incurred but typically lower than keeping the data in S3 Standard. +S3 Glacier Deep Archive (after 5 years): Offers the lowest storage cost for long-term archival (beyond 5 years) with retrieval times within 12 hours, meeting the auditor access requirement and minimizing ongoing storage costs.

A is wrong because "The images cannot be lost during this process" then you can use OneZone

https://aws.amazon.com/s3/storage-classes/glacier/#:~:text=S3%20Glacier%20Flexible%20Retrieval%20delivers,year%20and%20is%20retrieved%20asynchronously. S3 Glacier Flexible Retrieval delivers low-cost storage, up to 10% lower cost than S3 Glacier Instant Retrieval. Flexible retrieval is cheaper than Instant retrieval. S3 Glacier Flexible retrieval storage class provides minutes to 12 hours retrieval of data. Which is within the required time by auditors. --> We should select flexible retrieval. The design is not caring about the high availability. The design is caring about cost. One zone-IA is cheaper than standard IA. --> We should select One Zone IA.

"The images cannot be lost during this process" is a core requirement. The design cares about data loss and 5 years is a long time and AZ failure will result in data loss.

Selected Answer: C

"The images cannot be lost during this process" , imho this rules out S3 One zone infrequent access. S3 Glacier Instant Retrieval gives immediate access. S3 Glacier Flexible Retrieval does not give immediate access. so C.
