Which specification outlines how a filesystem bundle should be packaged into an image?

• A. OCI Image Specification
• B. Image Specification
• C. Runtime Specification
• D. Distribution Specification

Answer: (B)

The concept being tested is how container images are formed from a filesystem bundle. The Image Specification defines how the actual filesystem contents, along with metadata like the configuration and the list of layers, are packaged into an image and how those pieces are linked together in a manifest. This specification standardizes the layout so that tools can create images consistently and runtimes can interpret them correctly. The other specifications focus on different stages: the Runtime Specification describes how a container is executed, and the Distribution Specification covers pushing and pulling images from registries. The widely adopted standard that implements this packaging is the OCI Image Specification, but in this context, the term used to describe the packaging process itself is Image Specification.
