Exam AWS Certified Cloud Practitioner topic 1 question 363 discussion

Answer is B, question is asking for retrieve the files immediately. S3 Standard-IA is for data that is accessed less frequently, but requires rapid access when needed. https://aws.amazon.com/s3/storage-classes/

S3 Glacier Flexible Retrieval needs minutes or for bulk retrievals 5-12 hours https://aws.amazon.com/s3/storage-classes/glacier/

Answer is Glacier Instant Retrieval. The customer 'Rarely' retrieves the file and not 'less frequently' . So the answer is 'C'

C : glacier instant retrieval The key word is 'rarely' https://aws.amazon.com/s3/storage-classes/glacier/instant-retrieval/ Amazon S3 Glacier Instant Retrieval is an archive storage class that delivers the lowest-cost storage for long-lived data that is rarely accessed and requires retrieval in milliseconds S3 Standard-IA is for data that is accessed less frequently

B. S3 Standard-Infrequent Access (S3 Standard-IA) https://aws.amazon.com/s3/storage-classes/ "S3 Standard-IA is for data that is accessed less frequently, but requires rapid access when needed. S3 Standard-IA offers the high durability, high throughput, and low latency of S3 Standard, with a low per GB storage price and per GB retrieval charge. This combination of low cost and high performance make S3 Standard-IA ideal for long-term storage, backups, and as a data store for disaster recovery files. "

S3 Standard-Infrequent Access (S3 Standard-IA

https://aws.amazon.com/about-aws/whats-new/2021/11/amazon-s3-glacier-storage-class-amazon-s3-glacier-flexible-retrieval/ The key word is "Immediate". Choice "C" is for Flexible Retrieval. Availability is defined in the link above.

New type of Glacier Instant Retrieval. Is ideal for archive data that needs immediate access, such as medical images, news media assets, or user-generated content archives. With S3 Glacier Instant Retrieval, you can save up to 68% on storage costs compared to using the S3 Standard-Infrequent Access (S3 Standard-IA). https://aws.amazon.com/s3/storage-classes/

B is the answer.

B. S3 Standard-Infrequent Access (S3 Standard-IA) S3 Standard-Infrequent Access (S3 Standard-IA) is the most cost-effective storage class for infrequently accessed data, such as audio files that are 5 megabytes in size and are rarely accessed. S3 Standard-IA provides the same high durability, availability, and performance of S3 Standard storage at a lower cost, and it allows for immediate retrieval of files. The retrieval fees for S3 Standard-IA are less expensive than the fees for S3 Standard, and the data retrieval costs for S3 Standard-IA are lower than S3 Glacier Flexible Retrieval and S3 Glacier Deep Archive. The company should choose this class because it will have immediate access to the files and will pay less for storage and retrieval costs.

B is correct. Glacier means the files can't retrieve immediately.

You can choose from three archive storage classes optimized for different access patterns and storage duration. For archive data that needs immediate access, such as medical images, news media assets, or genomics data, choose the S3 Glacier Instant Retrieval storage class, an archive storage class that delivers the lowest cost storage with milliseconds retrieval. For archive data that does not require immediate access but needs the flexibility to retrieve large sets of data at no cost, such as backup or disaster recovery use cases, choose S3 Glacier Flexible Retrieval (formerly S3 Glacier), with retrieval in minutes or free bulk retrievals in 5-12 hours. To save even more on long-lived archive storage such as compliance archives and digital media preservation, choose S3 Glacier Deep Archive, the lowest cost storage in the cloud with data retrieval within twelve hours.
