1. [x] Set `jobs.example_matrix.strategy.max-parallel` to 2
1. [ ] Set `jobs.example_matrix.strategy.concurrency` to 2
1. [ ] Use GitHub's REST API to check if the job count is lesser than 2
1. [ ] It's not possible, a matrix will always run all of the jobs in parallel if there are runners available

### Is this statement true? `Docker container actions are usually slower than JavaScript actions`
> Docker container actions are slower than JavaScript actions
1. [x] True
1. [ ] False
> Because of the latency to build and retrieve the container, Docker container actions are slower than JavaScript actions.
### When creating a custom GitHub Action you have to store the source code in `.github/workflows` directory
> https://docs.github.com/en/actions/creating-actions/about-custom-actions#choosing-a-location-for-your-action
1. [x] False
1. [ ] True
> That is true for `workflows`, not for `actions`
### When creating custom GitHub Actions - in what file does all the action `metadata` have to be defined?
Metadata examples: name, description, outputs or required inputs
> https://docs.github.com/en/actions/creating-actions/metadata-syntax-for-github-actions
1. [x] In the `action.yml` or `action.yaml` file in the action repository
1. [ ] In the repository `README` file

1. [ ] It's edited in GitHub Marketplace UI when published for sharing
1. [ ] In the `action.yml` or `action.yaml` file in the action repository, but it is not required if the action is not meant to be shared and used by the public

> Re-running a workflow uses the same commit SHA and Git ref of the original event that triggered the workflow run.
1. [ ] You cannot re-run workflows in GitHub Actions. You have to trigger a new workflow which will run with latest changes
