A platform team wants a scheduled pipeline that bakes a fresh hardened machine image every week. Which EC2 Image Builder resource specifies the base image, the ordered software components to apply, and the storage settings for the output?
Show answer and explanation
Answer: B
An image recipe is the blueprint for the output AMI. It names a parent image, the build and test components applied in order, and the root volume storage settings. The image pipeline schedules builds and combines the recipe with an infrastructure configuration for the build instances and a distribution configuration that copies the finished image to other accounts and Regions.
Why the other options are wrong
- A. An infrastructure configuration describes the instance type, subnet, security groups, and IAM instance profile used while the build runs. It does not define the base image or the components.
- C. A distribution configuration controls where the finished image is copied, including target accounts, Regions, and tags applied to the outputs. It does not list the components or the parent image.
- D. A lifecycle policy automatically deprecates, disables, or deletes old image versions based on age or count. It does not specify what goes into a build.
