Which solution will meet these requirements?
Set up an AWS CloudTrail event that has a rule to identify all S3 buckets that are not versioning-enabled across Regions.
Use Amazon S3 Storage Lens to identify all S3 buckets that are not versioning-enabled across Regions.
Enable IAM Access Analyzer for S3 to identify all S3 buckets that are not versioning-enabled across Regions.
Create an S3 Multi-Region Access Point to identify all S3 buckets that are not versioning-enabled across Regions.
Explanations:
AWS CloudTrail is primarily used for logging and monitoring API calls, not for directly assessing the properties of S3 buckets such as versioning status. While it can log bucket creation and configuration changes, it doesn’t inherently provide a mechanism to identify non-versioned buckets across Regions.
Amazon S3 Storage Lens provides visibility into storage usage and activity trends across S3 buckets, including versioning status. It can generate reports that specifically include information about versioning, making it suitable for identifying buckets that are not versioning-enabled across multiple Regions.
IAM Access Analyzer for S3 focuses on analyzing resource policies and permissions to identify access risks, rather than the configuration settings of S3 buckets such as versioning status. It does not provide the capability to directly identify non-versioning-enabled buckets.
S3 Multi-Region Access Points are designed to simplify access to S3 buckets across Regions but do not assess the versioning status of those buckets. This option does not provide any functionality for identifying whether buckets are versioning-enabled or not.
