Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 373 discussion

Access patterns is given, therefore D is the most logical answer. Intelligent tiering is for random, unpredictable access.

I dont get how its A 1. Each morning, the company uses the data from the previous 30 days 2. Four times each year, the company uses the data from the previous 12 months to perform analysis and train other ML models 3. The data must be available with minimal delay for up to 1 year. After 1 year, the data must be retained for archival purposes The data ingestion happens 4 times a year, that means that after the initial 30 days it still needs to be pulled 3 more times, why would you put the data in standard infrequent if you were going to use it 3 more times and speed is a requirement? Makes more sense to put it in S3 standard, or intelligent then straight to glacier.

Clear access pattern. data in Standard-Infrequent Access is for data requires rapid access when needed

A and B, Intelligent Tiering cannot be configured. It is managed by AWS. C SIA does not allow immediate access for "each morning" D is best for 30 day standard access, SIA after 30 days and archive after 1 year

See reasoning below, just accidentally voted A

The data is used every day (typical use case for Standard) for 30 days, for the remaining 12 months it is used 3 or 4 times (typical use case for IA), after 12 months it is not used at all but must be kept (typical use case for Glacier Deep Archive).

This option optimizes costs while meeting the data access requirements: Store new data in S3 Standard for first 30 days of frequent access Transition to S3 Standard-IA after 30 days for infrequent access up to 1 year Archive to Glacier Deep Archive after 1 year for long-term archival

First 30 days data accessed every morning = S3 Standard Beyond 30 days data accessed quarterly = S3 Standard-Infrequent Access Beyond 1 year data retained = S3 Glacier Deep Archive

Option A meets the requirements most cost-effectively. The S3 Intelligent-Tiering storage class provides automatic tiering of objects between the S3 Standard and S3 Standard-Infrequent Access (S3 Standard-IA) tiers based on changing access patterns, which helps optimize costs. The S3 Lifecycle policy can be used to transition objects to S3 Glacier Deep Archive after 1 year for archival purposes. This solution also meets the requirement for minimal delay in accessing data for up to 1 year. Option B is not cost-effective because it does not include the transition of data to S3 Glacier Deep Archive after 1 year. Option C is not the best solution because S3 Standard-IA is not designed for long-term archival purposes and incurs higher storage costs. Option D is also not the most cost-effective solution as it transitions objects to the S3 Standard-IA tier after 30 days, which is unnecessary for the requirement to retrain the suite of ML models each morning using data from the previous 30 days.

Agree with UnluckyDucky , the correct option is D

Should be D. see this: https://www.examtopics.com/discussions/amazon/view/68947-exam-aws-certified-solutions-architect-associate-saa-c02/
