Your company has a set of EC2 Instances and also servers in their on-premises environment. The configuration management team wants to collect information on these servers, such as the softwares installed. For that, they can record it in their configuration management database. How could you achieve this in the easiest way possible?

Answer options:

A.Use the AWS Config tool to get the configuration of all the servers.
B.Use the AWS Systems Manager to get the software inventory on the servers.
C.Use the EC2 dashboard to get the configuration of all the servers.
D.Use Amazon Cloudwatch to get the configuration of all the servers.

Correct Answer: B
The AWS Documentation mentions the following.
You can use AWS Systems Manager Inventory to collect operating system (OS), application, and instance metadata from your Amazon EC2 instances and your on-premises servers or virtual machines (VMs) in your hybrid environment. You can query the metadata to quickly understand which instances are running the software and configurations required by your software policy, and which instances need to be updated.
Option A is incorrect because this can check for the configuration changes in resources, but not get information on the actual software installed on the servers.
Option C is incorrect because the dashboard does not have this information available.
Option D is incorrect because you can get logs and metrics from Cloudwatch but not get the list of software installed.
