Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
To store and distribute container images
Why this is correct
Container registries like Docker Hub, Google Container Registry, or AWS ECR store images and allow them to be pulled by Kubernetes or other systems.
- ✗
To run unit tests on container images
Why it's wrong here
Unit tests are run during CI, not by the registry.
- ✗
To store application source code
Why it's wrong here
Source code is typically stored in a version control system like Git, not a container registry.
- ✗
To scan images for vulnerabilities
Why it's wrong here
While some registries offer scanning, the primary purpose is storage and distribution, not scanning.
