Exam AWS-SysOps topic 1 question 854 discussion

Amazon S3 inventory is a feature that provides a detailed list of all the objects in an S3 bucket on a daily or weekly basis. When you enable S3 inventory for a bucket, it generates a report that includes the metadata and other details of each object in the bucket. By using Amazon S3 inventory, you can get an accurate and comprehensive list of all the objects in the bucket, including their total count. This feature ensures consistency and reliability in reporting the number of objects, as the inventory data is generated and stored independently from CloudWatch and CLI-based reports.

B. Amazon S3 inventory

Answerer is B Amazon S3 inventory https://docs.aws.amazon.com/AmazonS3/latest/dev/storage-inventory.html Amazon S3 inventory is one of the tools Amazon S3 provides to help manage your storage. You can use it to audit and report on the replication and encryption status of your objects for business, compliance, and regulatory needs. You can also simplify and speed up business workflows and big data jobs using Amazon S3 inventory, which provides a scheduled alternative to the Amazon S3 synchronous List API operation. Amazon S3 inventory provides comma-separated values (CSV), Apache optimized row columnar (ORC) or Apache Parquet (Parquet) output files that list your objects and their corresponding metadata on a daily or weekly basis for an S3 bucket or a shared prefix (that is, objects that have names that begin with a common string). If weekly, a report is generated every Sunday (UTC timezone) after the initial report. For information about Amazon S3 inventory pricing, see Amazon S3 Pricing.

B. Amazon S3 inventory Seem correct

I'll go with B

B. Amazon S3 inventory https://docs.aws.amazon.com/AmazonS3/latest/dev/storage-inventory.html

B is correct...Because C is not specific...

For me it is B. Amazon S3 inventory helps you manage your storage by creating lists of the objects in an S3 bucket on a defined schedule. The inventory lists are published to CSV, ORC, or Parquet files in a destination bucket.

Ridiculous options. I am going with option C. It should've been more specific. From S3 management console -> bucket -> Actions -> Get Total size. (this gives the total size and number of objects in the bucket definitively)
