A company has about 100 Amazon Linux EC2 instances. You want to use Amazon Inspector to test the security state of applications that run on these instances so that the security exposure, vulnerabilities, and deviations from security best practices are reported.
Amazon Inspector needs to be installed before performing the host assessments.
Which method can quickly install the Amazon Inspector Agent on all required EC2 instances?

Answer options:

A.Use the “Amazon Linux AMI with Amazon Inspector Agent” for the EC2 instances. The Inspector optimized AMI preinstalled the Inspector agent. So, no further actions are required.
B.Use “wget https://inspector-agent.amazonaws.com/linux/latest/install” to install the agent on EC2 instances.
C.Use an Ansible inventory document to manage EC2 instances and an Ansible playbook to install the agent on multiple EC2 instances at the same time.
D.Install the agent on multiple EC2 instances using the Systems Manager Run Command. The command document is AmazonInspector-ManageAWSAgent.

Answer: D
Option A is incorrect because a large number of EC2 instances may have to change the AMI with a preinstalled Inspector agent. This would be time-consuming and not an efficient way to achieve the asks.
Option B is incorrect because installing agents on each machine manually is time-consuming work and not an efficient way to achieve the asks.
Option C is incorrect because users need to maintain Ansible files and playbook to install the inspector agent. This would be time-consuming and not an efficient way to achieve the asks.
Option D is CORRECT because AWS Systems Manager Run Command can easily install the Inspector agent on selected EC2 instances. This method should be able to manage multiple instances at the same time.
