Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 83 discussion

Storage class: After you configure a filter, you'll start seeing data analysis based on the filter in the Amazon S3 console in 24 to 48 hours. However, storage class analysis observes the access patterns of a filtered data set for 30 days or longer to gather information for analysis before giving a result Storage Lens: All S3 Storage Lens metrics are retained for a period of 15 months. However, metrics are only available for queries for a specific duration, which depends on your metrics selection. This duration can't be modified. Free metrics are available for queries for a 14-day period, and advanced metrics are available for queries for a 15-month period. You have to upgrade regardless to query up to 12 months

Both B and C are good. I guess AWS wants clients to use S3 Storage Lens... Hence I vote C.

C, for sure.

B ..S3 Storage Class Analysis is specifically designed to help you analyze storage access patterns. It monitors the access patterns of objects and provides insights into when it is appropriate to transition objects to different storage classes .

C, S3 Storage Lens offers comprehensive visibility into storage usage and activity trends across the AWS Organization, facilitating informed decisions on cost optimization and storage efficiency

Option C refers to using Amazon S3 Storage Lens, which provides organization-wide visibility into object storage usage and activity trends. By upgrading to include advanced metrics and recommendations, users can access detailed insights that help optimize storage costs across their S3 resources. S3 Storage Lens offers dashboard views and metrics that can directly inform on the appropriate storage class based on actual usage patterns, making it a comprehensive solution for the stated requirements.

Amazon S3 Storage Class Analysis: Amazon S3 provides a Storage Class Analysis tool that helps you analyze access patterns to your S3 objects over time. You can enable it on your S3 bucket to collect data on object access patterns.

Answer is B.

To me here the key sentence is "review data trends for the past 12 months" A = CUR provides detailed usage data but it is not the best tool for this job B = S3 storage class analysis provides recommendation for Standard and Standard IA storage classes, but does not provide data trends C = correct D = Access Analyzer provides visibility for buckets that are configured to allow access to anyone on the internet or other AWS accounts

B is the right answer, because it suffices a bucket analysis --> https://docs.aws.amazon.com/AmazonS3/latest/userguide/analytics-storage-class.html C instead is a solution for a more organization-wide analysis of bucket --> https://docs.aws.amazon.com/AmazonS3/latest/userguide/storage_lens.html

see AMohanty answer

S3 Storage Class Analysis enables you to monitor access patterns across objects to help you decide when to transition data to the right storage class to optimize costs.

C Storage Class is only used for recommendation for Standard to Standard IA

Option B: Amazon S3's Storage Class Analysis function is mainly used to analyze the access patterns of objects in S3 buckets so that you can transfer these objects to the most cost-effective storage class. However, this feature does not provide detailed historical data for the past 12 months; it is more about observing current usage patterns and making the best storage class decisions based on those patterns. If you need detailed storage trends and object status over the past 12 months, option C (using Amazon S3 Storage Lens) may be a better choice. Amazon S3 Storage Lens provides comprehensive storage analysis, including historical trends and advanced metrics, which may be more suitable for analyzing long-term data and storage conditions.

I choose C. B. Storage class analysis only provides recommendations for Standard to Standard IA classes. The company uses a variety of storage classes.

a hard one ... I guess C, but could be B :/

By using Amazon S3 analytics Storage Class Analysis you can analyze storage access patterns to help you decide when to transition the right data to the right storage class. This new Amazon S3 analytics feature observes data access patterns to help you determine when to transition less frequently accessed STANDARD storage to the STANDARD_IA (IA, for infrequent access) storage class. So it meet the qn objective of identify the appropriate storage class for the objects
