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

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

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

Key - high availability and resiliency Key-the data to remain immediately accessible Its not C or D because its One zone its no B even if glacier is cheaper the problem is that data must be immediately accesible so the answer is B

Option B

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

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.

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.

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.
