Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 551 discussion

Answer is A Amazon S3 Glacier: Expedited Retrieval: Provides access to data within 1-5 minutes. Standard Retrieval: Provides access to data within 3-5 hours. Bulk Retrieval: Provides access to data within 5-12 hours. Amazon S3 Glacier Deep Archive: Standard Retrieval: Provides access to data within 12 hours. Bulk Retrieval: Provides access to data within 48 hours.

All the "....after 7 days" options are wrong. Before you transition objects to S3 Standard-IA or S3 One Zone-IA, you must store them for at least 30 days in Amazon S3 https://docs.aws.amazon.com/AmazonS3/latest/userguide/lifecycle-transition-general-considerations.html#:~:text=Minimum%20Days%20for%20Transition%20to%20S3%20Standard%2DIA%20or%20S3%20One%20Zone%2DIA

there's a period before you can transition to any storage class (down the hierarchy) "except for glacier of all types" a minimum of 30 days. However, when transitioning to Glacier directly there's no minimum period to wait so you can choose "A" safely

Its A ya bunch of nerds

C is incorrect. Unsupported lifecycle transitions Amazon S3 does not support any of the following lifecycle transitions. You can't transition from the following: Any storage class to the S3 Standard storage class. Any storage class to the Reduced Redundancy Storage (RRS) class. The S3 Intelligent-Tiering storage class to the S3 Standard-IA storage class. The S3 One Zone-IA storage class to the S3 Intelligent-Tiering, S3 Standard-IA, or S3 Glacier Instant Retrieval storage classes. https://docs.aws.amazon.com/AmazonS3/latest/userguide/lifecycle-transition-general-considerations.html

BC are lifecycle with tiering and infrequent access which are not required here. D is deep archive and can take hours to retrieve so it is not suitable A is cheapest workable option

frequent access pattern- Standard.

Not B - More expensive than A Not C - Intelligent-Tiering moves only objects of at least 128 KB Not D - Glacier Deep Archive takes more than 6 hours to retrieve

Any option with S3 Intelligent-Tiering is out, this is only required when the access patterns are unknown. From the question the access patterns are well known, enough to tie the frequently accessed reports to S3 standard and transition them to S3 glacier after 7days.

its A for me

Tiene mas sentido

Option A Amazon S3 Glacier Standard Retrieval: Provides access to data within 3-5 hours.

most cost effective has to be glacier so A With C it is using intelligence tiering which is 30 days minimum from what I have read, I may be wrong on how I read that.

answer A frequent access during the first week -> keeps data in s3 standard for 7 days stored for several year and retrievable within 6 hours -> can be moved to s3 glacier for data archive purpose

Its A. Data cannot be transitioned from Intelligent Tiering to Standard IA https://docs.aws.amazon.com/AmazonS3/latest/userguide/lifecycle-transition-general-considerations.html

Check Oayoade comment, before transition, 30 days in S3 the files have to be, young padawans
