A developer is examining a workflow file and sees the following trigger configuration: ```yaml on: push: branches: - main ``` When will this workflow run?

When a pull request is opened against the main branch

When a scheduled cron job runs at a specified time

When code is pushed to the main branch

When any branch is pushed, including feature branches

Consider the following YAML snippet: ```yaml defaults: &defaults runs-on: ubuntu-latest job1: <<: *defaults steps: - run: echo "Hello" ``` What is the effective value of `runs-on` for `job1`?

The value is inherited from the repository's default runner

An error occurs because anchors cannot be used in workflows

Given the following YAML: ```yaml common: &common env: NODE_ENV: production job: <<: *common env: DEBUG: true ``` What is the effective `env` for `job` after YAML expansion?

NODE_ENV: production and DEBUG: true

An error occurs because `env` is defined twice

In a workflow job log, what does a step with a green checkmark (✓) indicate?

The step failed but the workflow continued

The step was skipped due to a condition

The step completed successfully

A workflow with a matrix strategy has 8 jobs. The run failed for 2 jobs: `build (ubuntu-latest, 16)` and `build (windows-latest, 14)`. The logs for `build (ubuntu-latest, 16)` show a compilation error in a C++ file. The logs for `build (windows-latest, 14)` show a different error: `The system cannot find the file specified.` The developer suspects a common cause. What is the most likely common cause?

The matrix strategy is misconfigured, causing the jobs to use the wrong operating system.

A missing dependency that is required by both the C++ compiler and the file lookup.

The `ubuntu-latest` runner is out of memory, and the `windows-latest` runner is out of disk space.

A syntax error in the workflow file that only affects certain matrix combinations.
