Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 606 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 606
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A solutions architect is designing an application that will allow business users to upload objects to Amazon S3. The solution needs to maximize object durability. Objects also must be readily available at any time and for any length of time. Users will access objects frequently within the first 30 days after the objects are uploaded, but users are much less likely to access objects that are older than 30 days.

Which solution meets these requirements MOST cost-effectively?

  • A. Store all the objects in S3 Standard with an S3 Lifecycle rule to transition the objects to S3 Glacier after 30 days.
  • B. Store all the objects in S3 Standard with an S3 Lifecycle rule to transition the objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days.
  • C. Store all the objects in S3 Standard with an S3 Lifecycle rule to transition the objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) after 30 days.
  • D. Store all the objects in S3 Intelligent-Tiering with an S3 Lifecycle rule to transition the objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days.

Selected Answer: B
Minimum Days for Transition to S3 Standard-IA or S3 One Zone-IA 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. For example, you cannot create a Lifecycle rule to transition objects to the S3 Standard-IA storage class one day after you create them. Amazon S3 doesn't support this transition within the first 30 days because newer objects are often accessed more frequently or deleted sooner than is suitable for S3 Standard-IA or S3 One Zone-IA storage. Similarly, if you are transitioning noncurrent objects (in versioned buckets), you can transition only objects that are at least 30 days noncurrent to S3 Standard-IA or S3 One Zone-IA storage. https://docs.aws.amazon.com/AmazonS3/latest/userguide/lifecycle-transition-general-considerations.html

Answer is B. C is wrong because one-zone doesn't maximize durability, it compromises it.

No, both Standard-IA and OZ-IA have SAME durability. What differs it the availability. Durability is calculated based on how many times the data is copied and made redundant, inherently by the service itself. But that redundancy can be across one building (AZ) or multiple availability zones.

I believe it's C. The following link mentions One Zone-IA offers 99.999999999% durability. Questions says nothing about HA

B Intelligent tiering will automatically transition to S3 One Zone-IA which is not needed for durability.

A S3 Glacier is most cost effective

Between A & B, this is the tie-breaker: "Objects also must be readily available at any time and for any length of time" While Glacier IS more cost effective but it won't make the objects readily available at any time for any duration.... this is only possible with IA.
