Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 534 discussion

C seems the most sutiable. Is the lowest cost. After 30 days is backup only, doesn't specify frequent access. Therefor we must transition the items after 30 days to Glacier Flexible Retrieval. Also it says deletion after 90 days, so all answers specifying a transition after 90 days makes no sense.

The Glacier min storage duration is 90 days. All the options using Glacier are wrong. Only A is feasible.

A: When logs are created, they are initially automatically created to S3 Standard. What are you transitioning anyway? B & D: You could've just deleted logs after 90 days. No need to move them somewhere else then delete them. That's just money down the drain.

C: Lowest cost

Not A: Objects are created in S3 Standard, so it doesn't make sense to 'transition' them there "30 days after creation" Not B or C: No need to "move all objects to the S3 Glacier Flexible Retrieval storage class after 90 days" because we want to delete, not archive, them. Even if we would delete them right after moving, we would pay 90 days minimum storage duration. Plus, we are using "Infrequent Access" classes here, but we have no access at all.

requirement : frequently analysis search cost : S3 STD 0.0004 vs IA 0.001 so IA is more expensive than STD(A)

C is most cost-effective

Things to note are: 30 days frequent access and 90 days after creation, so you only need to do 2 things, not 3. Objects in S3 will be stored by default for 30 days before you can move it to somewhere else, so C is the answer. https://docs.aws.amazon.com/AmazonS3/latest/userguide/lifecycle-transition-general-considerations.html

C is the correct one . As after 30 days it doesn't says about access / retrieval , only backup so move items after 30 days to Glacier Flexible Retrieval. And after it says deletion , so expiration action will ensure that the objects are deleted after 90 days, even if they are not accessed

I think - it is B The first 30 days, the logs need to be highly available for frequent analysis. The S3 Standard storage class is the most expensive storage class, but it also provides the highest availability. After 30 days, the logs still need to be retained for backup purposes, but they do not need to be accessed frequently. The S3 Standard-IA storage class is a good option for this, as it is less expensive than the S3 Standard storage class. After 90 days, the logs can be moved to the S3 Glacier Flexible Retrieval storage class. This is the most cost-effective storage class for long-term archiving. The expiration action will ensure that the objects are deleted after 90 days, even if they are not accessed

C is the most cost effective solution.

C most likely.

Question says "All logs must be highly available for 30 days for frequent analysis" I think the answer is A. Glacier is not made for frequent access.

I think B
