Correct answer & explanation
✓
They are portable across different container runtimes
OCI images are composed of layers (read-only) and are built from a Dockerfile. They are lightweight and portable across different runtimes. They do not include a guest OS (unlike VMs), and they are not tied to a specific runtime.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
They are portable across different container runtimes
Why this is correct
OCI standards ensure portability.
- ✓
They are composed of layers that can be cached and reused
Why this is correct
OCI images use layered filesystems for efficiency.
- ✗
They include a full guest operating system
Why it's wrong here
Containers share the host OS kernel; they do not include a guest OS.
- ✗
They can only be run by Docker
Why it's wrong here
OCI images are runtime-agnostic; any OCI-compliant runtime can run them.
- ✗
They require a hypervisor to run
Why it's wrong here
Containers do not use hypervisors.
