Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 356 discussion

One -zone -infrequent access cannot be the answer because it requires high availability so standard infrequent access should be the answer

Option B

high availability, resiliency = multi AZ 75% of the data is rarely accessed but remain immediately accessible = Standard-Infrequent Access

The correct answer is B. S3 Standard-IA is a storage class that is designed for infrequently accessed data. It offers lower storage costs than S3 Standard, but it has a retrieval latency of 1-5 minutes.

Highly available so One Zone IA is out the question Glacier Deep archive isn't immediately accessible 12-48 hours B is the answer.

S3 Glacier Deep Archive is intended for data that is rarely accessed and can tolerate retrieval times measured in hours. Moving data to S3 One Zone-IA immediately would not meet the requirement of immediate accessibility with the same high availability and resiliency.

The answer should be C. S3 One Zone-IA is for data that is accessed less frequently but requires rapid access when needed. Unlike other S3 Storage Classes which store data in a minimum of three Availability Zones (AZs), S3 One Zone-IA stores data in a single AZ and costs 20% less than S3 Standard-IA. https://aws.amazon.com/s3/storage-classes/#:~:text=S3%20One%20Zone%2DIA%20is,less%20than%20S3%20Standard%2DIA.

Needs immediate accessibility after 30days, IF they need to be accessed.

S3 Standard-Infrequent Access after 30 days

B Option B - Move the data objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days - will meet the requirements of keeping the data immediately accessible with high availability and resiliency, while minimizing storage costs. S3 Standard-IA is designed for infrequently accessed data, and it provides a lower storage cost than S3 Standard, while still offering the same low latency, high throughput, and high durability as S3 Standard.
