A company stores its data objects in Amazon S3 Standard storage. A solutions architect has found that 75% of the data is rarely accessed after 30 days. The company needs all the data to remain immediately accessible with the same high availability and resiliency, but the company wants to minimize storage costs.
Which storage solution will meet these requirements?
The company needs to minimize storage costs while ensuring that data remains immediately accessible with high availability and resiliency. S3 Standard-Infrequent Access (S3 Standard-IA) is designed for infrequently accessed data but still provides high availability and low latency similar to S3 Standard storage. S3 Standard-IA is cost-effective because it charges less for storage and is suitable for data that is accessed less frequently. Moving data to S3 Standard-IA after 30 days meets the company's requirements of maintaining accessibility and durability while reducing costs.
One -zone -infrequent access cannot be the answer because it requires high availability so standard infrequent access should be the answer
Highly available so One Zone IA is out the question Glacier Deep archive isn't immediately accessible 12-48 hours B is the answer.
Needs immediate accessibility after 30days, IF they need to be accessed.
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.
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 Standard-Infrequent Access after 30 days
Option B
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.
The Question emphasises to kepp same high availability class - S3 One Zone-IA doesnt support multiple Availability Zone data resilience model like S3 Standard-Infrequent Access.
