An Internal Security Audit of AWS Resources Within a Company

question 155

Multiple Choice

An internal security audit of AWS resources within a company found that a number of Amazon EC2 instances running Microsoft Windows workloads were missing several important operating system-level patches. A Solutions Architect has been asked to fix existing patch deficiencies, and to develop a workflow to ensure that future patching requirements are identified and taken care of quickly. The Solutions Architect has decided to use AWS Systems Manager. It is important that EC2 instance reboots do not occur at the same time on all Windows workloads to meet organizational uptime requirements. Which workflow will meet these requirements in an automated manner?

• A) Add a Patch Group tag with a value of Windows Servers to all existing EC2 instances. Ensure that all Windows EC2 instances are assigned this tag. Associate the AWS-DefaultPatchBaseline to the Windows Servers patch group. Define an AWS Systems Manager maintenance window, conduct patching within it, and associate it with the Windows Servers patch group. Register instances with the maintenance window using associated subnet IDs. Assign the AWS-RunPatchBaseline document as a task within each maintenance window.
• B) Add a Patch Group tag with a value of Windows Servers to all existing EC2 instances. Ensure that all Windows EC2 instances are assigned this tag. Associate the AWS-WindowsPatchBaseline to the Windows Servers patch group. Create an Amazon CloudWatch Events rule configured to use a cron expression to schedule the execution of patching using the AWS Systems Manager run command. Assign the AWS-RunWindowsPatchBaseline document as a task associated with the Windows Servers patch group. Create an AWS Systems Manager State Manager document to define commands to be executed during patch execution. Add a Patch Group tag with a value of Windows Servers to all existing EC2 instances. Ensure that all Windows EC2 instances are assigned this tag. Associate the AWS-WindowsPatchBaseline to the Windows Servers patch group. Create an Amazon CloudWatch Events rule configured to use a cron expression to schedule the execution of patching using the AWS Systems Manager run command. Assign the AWS-RunWindowsPatchBaseline document as a task associated with the Windows Servers patch group. Create an AWS Systems Manager State Manager document to define commands to be executed during patch execution.
• C) Add a Patch Group tag with a value of either Windows Servers1 or Windows Servers2 to all existing EC2 instances. Ensure that all Windows EC2 instances are assigned this tag. Associate the AWS-DefaultPatchBaseline with both Windows Servers patch groups. Define two non-overlapping AWS Systems Manager maintenance windows, conduct patching within them, and associate each with a different patch group. Register targets with specific maintenance windows using the Patch Group tags. Assign the AWS-RunPatchBaseline document as a task within each maintenance window.
• D) Add a Patch Group tag with a value of either Windows Servers1 or Windows Server2 to all existing EC2 instances. Ensure that all Windows EC2 instances are assigned this tag. Associate the AWS-WindowsPatchBaseline with both Windows Servers patch groups. Define two non-overlapping AWS Systems Manager maintenance windows, conduct patching within them, and associate each with a different patch group. Assign the AWS-RunWindowsPatchBaseline document as a task within each maintenance window. Create an AWS Systems Manager State Manager document to define commands to be executed during patch execution.
