Resource Configuration History

Answer - B.

The AWS documentation mentions the following.

A configuration history is a collection of the configuration items for a given resource over any time period.

A configuration history can help you answer questions about, for example, when the resource was first created, how the resource has been configured over the last month, and what configuration changes were introduced yesterday at 9 AM.

The configuration history is available to you in multiple formats.

AWS Config automatically delivers a configuration history file for each resource type that is being recorded to an Amazon S3 bucket that you specify.

You can select a given resource in the AWS Config console and navigate to all previous configuration items for that resource using the timeline.

Additionally, you can access the historical configuration items for a resource from the API.

The correct answer to the question is B. Configuration History.

AWS Config is a service that allows you to assess, audit, and evaluate the configurations of your AWS resources. It provides a detailed view of the resource inventory and their configuration changes, which is helpful in terms of compliance auditing, troubleshooting, and security analysis.

In AWS Config, a Configuration Item (CI) represents the configuration of a resource at a particular point in time. AWS Config records the state of each resource at a specific time and tracks any configuration changes to that resource over time.

The Configuration History is a collection of all the configuration items that have been recorded for a given resource over time. It includes the details of all changes made to the resource configuration, including the time and date of each change, the person or service that made the change, and the previous and current configuration states. Configuration history is stored in Amazon S3 and is available for 7-14 days.

Configuration Recorder is a component of AWS Config that continuously records changes made to AWS resources and stores the configuration data in S3. The Configuration Stream is an Amazon Kinesis Data Stream that enables you to receive notifications when configuration changes occur. Finally, Configuration Snapshot is a point-in-time backup of the configuration settings for a resource.

In summary, the Configuration History is a collection of all the configuration items for a resource over any time.
