Question 3

A workflow running on a GitHub-hosted ubuntu-latest runner needs Node.js 20 but the maintainer wants to confirm whether that version is already available in the runner's tool cache before adding a setup-node step, to avoid an unnecessary download at runtime. Where should the maintainer look to authoritatively confirm the preinstalled Node.js versions for the current ubuntu-latest image?

Accepted Answer

The GitHub Actions runner image release notes (the runner-images repository README/software list) for the Ubuntu image version

Answer

The organization's Actions usage policy allow list in enterprise settings

Answer

The output of the actions/cache action's restore step in a previous run

Answer

The runner group configuration page under organization Actions settings

Question 4

You are authoring a JavaScript action. Your team recently migrated the codebase to target the latest supported Node.js runtime on GitHub-hosted runners. In action.yml, the current metadata block reads:

runs:
  using: 'node16'
  main: 'dist/index.js'

Runners have begun emitting deprecation warnings, and you want the action to execute on the current default Node runtime. Which single change to the metadata correctly updates the action?

Accepted Answer

Change the value of the `using` key to `node24`.

Answer

Add a `node-version: 20` key alongside `main` under `runs`.

Answer

Change `using` to `javascript` and add `runtime: node20`.

Answer

Set `using: docker` and reference a Node 20 base image in an `image` key.

Question 5

As an organization owner, you define a configuration variable named DEPLOY_REGION at the organization level. You want only three specific repositories out of the 40 in your organization to be able to read this variable in their workflows. When creating the variable via the GitHub UI, which access configuration should you choose?

Accepted Answer

Set the variable's repository access to "Selected repositories" and add the three repositories to the list

Answer

Set the variable's repository access to "All repositories" and rely on branch protection rules in the three repos

Answer

Create the variable as an environment variable in each of the three repositories instead

Answer

Set the variable's repository access to "Private repositories" so only internal repos can read it
