Question 857 - SAA-C03 discussion

Export

A company wants to implement new security compliance requirements for its development team to limit the use of approved Amazon Machine Images (AMIs).

The company wants to provide access to only the approved operating system and software for all its Amazon EC2 instances. The company wants the solution to have the least amount of lead time for launching EC2 instances.

Which solution will meet these requirements?

A.

Create a portfolio by using AWS Service Catalog that includes only EC2 instances launched with approved AMIs. Ensure that all required software is preinstalled on the AMIs. Create the necessary permissions for developers to use the portfolio.

Answers
A.

Create a portfolio by using AWS Service Catalog that includes only EC2 instances launched with approved AMIs. Ensure that all required software is preinstalled on the AMIs. Create the necessary permissions for developers to use the portfolio.

B.

Create an AMI that contains the approved operating system and software by using EC2 Image Builder. Give developers access to that AMI to launch the EC2 instances.

Answers
B.

Create an AMI that contains the approved operating system and software by using EC2 Image Builder. Give developers access to that AMI to launch the EC2 instances.

C.

Create an AMI that contains the approved operating system Tell the developers to use the approved AMI Create an Amazon EventBridge rule to run an AWS Systems Manager script when a new EC2 instance is launched. Configure the script to install the required software from a repository.

D.

Create an AWS Config rule to detect the launch of EC2 instances with an AMI that is not approved. Associate a remediation rule to terminate those instances and launch the instances again with the approved AMI. Use AWS Systems Manager to automatically install the approved software on the launch of an EC2 instance.

Answers
D.

Create an AWS Config rule to detect the launch of EC2 instances with an AMI that is not approved. Associate a remediation rule to terminate those instances and launch the instances again with the approved AMI. Use AWS Systems Manager to automatically install the approved software on the launch of an EC2 instance.

Suggested answer: A

Explanation:

AWS Service Catalog is designed to allow organizations to manage a catalog of approved products (including AMIs) that users can deploy. By creating a portfolio that contains only EC2 instances launched with preapproved AMIs, the company can enforce compliance with the approved operating system and software for all EC2 instances. Service Catalog also streamlines the process of launching EC2 instances, reducing the lead time while ensuring that developers use only the approved configurations.

Option B (EC2 Image Builder): While EC2 Image Builder helps in creating and managing AMIs, it doesn't provide the enforcement mechanism that Service Catalog does.

Option C (EventBridge rule and Systems Manager script): This solution is reactive and involves more operational complexity compared to Service Catalog.

Option D (AWS Config rule): This option is reactive (it terminates non-compliant instances after launch) and introduces additional operational overhead.
