You are working in a big organization as an AWS Solutions Architect. At the moment, the company is managing AWS AMIs in different ways without a common pattern. Different teams follow their own processes to create AMIs based on various pipelines. You plan to standardize the creation and management of AMIs through EC2 Image Builder. Which of the following benefits can you achieve with EC2 Image Builder? (Select TWO)

Answer options:

A.EC2 Image Builder pipelines always use the latest operating system in which the latest security patches are installed.
B.In an EC2 Image Builder pipeline, users can choose to install Amazon managed components such as the CloudWatch agent and the CodeDeploy agent.
C.With an EC2 Image Builder pipeline, users can automatically deploy the AMIs in EC2 instances or Auto Scaling groups in different AWS Regions.
D.In an EC2 Image Builder pipeline, the generated AMIs can be automatically distributed to multiple AWS Regions or shared with other AWS accounts.
E.EC2 Image Builder pipelines are based on Packer so that Packer templates can be reused.

Correct Answers: B and D
Option A is incorrect because the operating system versions can be customized. Users can choose a particular OS version based on their needs.
Option B is CORRECT because users can customize components to build their desired output AMIs. Take the following as an example:
Option C is incorrect because AMIs cannot be automatically deployed on EC2 instances. The image pipeline provides an automation framework for building secure AMIs and container images on AWS.
Option D is CORRECT because EC2 Image Builder supports this. The generated AMIs can be distributed through an AMI pipeline.
Option E is incorrect because EC2 Image Builder utilizes image recipes, and Packer templates cannot be used by EC2 Image Builder.
