S3 Storage Classes

Each month, a leasing firm prepares and delivers PDF statements to all of its clients. Each statement is around 400 KB in length. Customers may obtain their statements from the website for a period of up to 30 days after they are created. Customers are sent a ZIP file containing all of their statements at the conclusion of their three-year lease. Which storage method is the MOST cost-effective in this situation?

• Store the statements using the Amazon S3 Standard storage class. Create a lifecycle policy to move the statements to Amazon S3 Glacier storage after 1 day

• Store the statements using the Amazon S3 Glacier storage class. Create a lifecycle policy to move the statements to Amazon S3 Glacier Deep Archive storage after 30 days

• Store the statements using the Amazon S3 Standard storage class. Create a lifecycle policy to move the statements to Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA) storage after 30 days

• Store the statements using the Amazon S3 Standard-Infrequent Access (S3 Standard-IA) storage class. Create a lifecycle policy to move the statements to Amazon S3 Glacier storage after 30 days

A leading video streaming service delivers billions of hours of content from Amazon S3 to customers around the world. Amazon S3 also serves as the data lake for its big data analytics solution. The data lake has a staging zone where intermediary query results are kept only for 24 hours. These results are also heavily referenced by other parts of the analytics pipeline.

Which of the following is the MOST cost-effective strategy for storing this intermediary query data?

• Store the intermediary query results in S3 Standard storage class

• Store the intermediary query results in S3 Glacier Instant Retrieval storage class

• Store the intermediary query results in S3 Standard-Infrequent Access storage class

• Store the intermediary query results in S3 One Zone-Infrequent Access storage class

A media agency stores its re-creatable assets on Amazon S3 buckets. The assets are accessed by a large number of users for the first few days and the frequency of access falls down drastically after a week. Although the assets would be accessed occasionally after the first week, but they must continue to be immediately accessible when required. The cost of maintaining all the assets on S3 storage is turning out to be very expensive and the agency is looking at reducing costs as much as possible.

As a Solutions Architect, can you suggest a way to lower the storage costs while fulfilling the business requirements?

• Configure a lifecycle policy to transition the objects to Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA) after 30 days

• Configure a lifecycle policy to transition the objects to Amazon S3 Standard-Infrequent Access (S3 Standard-IA) after 7 days

• Configure a lifecycle policy to transition the objects to Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA) after 7 days

• Configure a lifecycle policy to transition the objects to Amazon S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days

An audit department generates and accesses the audit reports only twice in a financial year. The department uses AWS Step Functions to orchestrate the report creating process that has failover and retry scenarios built into the solution. The underlying data to create these audit reports is stored on S3, runs into hundreds of Terabytes and should be available with millisecond latency.

As a solutions architect, which is the MOST cost-effective storage class that you would recommend to be used for this use-case?

• Amazon S3 Standard

• Amazon S3 Intelligent-Tiering (S3 Intelligent-Tiering)

• Amazon S3 Standard-Infrequent Access (S3 Standard-IA)

• Amazon S3 Glacier Deep Archive

You have an S3 bucket that contains files in two different folders - s3://my-bucket/images and s3://my-bucket/thumbnails. When an image is first uploaded and new, it is viewed several times. But after 45 days, analytics prove that image files are on average rarely requested, but the thumbnails still are. After 180 days, you would like to archive the image files and the thumbnails. Overall you would like the solution to remain highly available to prevent disasters happening against a whole AZ.

How can you implement an efficient cost strategy for your S3 bucket? (Select two)

• Create a Lifecycle Policy to transition all objects to S3 Standard IA after 45 days

• Create a Lifecycle Policy to transition objects to S3 Standard IA using a prefix after 45 days

• Create a Lifecycle Policy to transition all objects to Glacier after 180 days

• Create a Lifecycle Policy to transition objects to Glacier using a prefix after 180 days

• Create a Lifecycle Policy to transition objects to S3 One Zone IA using a prefix after 45 days

A medical devices company uses S3 buckets to store critical data. Hundreds of buckets are used to keep the data segregated and well organized. Recently, the development team noticed that the lifecycle policies on the S3 buckets have not been applied optimally, resulting in higher costs.

As a Solutions Architect, can you recommend a solution to reduce storage costs on S3 while keeping the IT team's involvement to a minimum?

• Configure Amazon Elastic File System (Amazon EFS) to provide a fast, cost-effective and sharable storage service

• Use S3 Intelligent-Tiering storage class to optimize the S3 storage costs

• Use S3 One Zone-Infrequent Access, to reduce the costs on S3 storage

• Use S3 Outposts storage class to reduce the costs on S3 storage by storing the data on-premises

A media company is evaluating the possibility of moving its IT infrastructure to the AWS Cloud. The company needs at least 10 TB of storage with the maximum possible I/O performance for processing certain files which are mostly large videos. The company also needs close to 450 TB of very durable storage for storing media content and almost double of it, i.e. 900 TB for archival of legacy data.

As a Solutions Architect, which set of services will you recommend to meet these requirements?

• Amazon EC2 instance store for maximum performance, Amazon S3 for durable data storage, and Amazon S3 Glacier for archival storage

• Amazon S3 standard storage for maximum performance, Amazon S3 Intelligent-Tiering for intelligent, durable storage, and Amazon S3 Glacier Deep Archive for archival storage

• Amazon EBS for maximum performance, Amazon S3 for durable data storage, and Amazon S3 Glacier for archival storage

• Amazon EC2 instance store for maximum performance, AWS Storage Gateway for on-premises durable data access and Amazon S3 Glacier Deep Archive for archival storage
