Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A workflow with an on.push trigger for the main branch
GitHub Actions workflows are defined in YAML and can include an 'on' trigger specifying events such as push to a branch. This allows automation of the deployment when code is pushed to main.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A cron job that checks the repository every hour
Why it's wrong here
A scheduled trigger would be inefficient and not event-driven.
- ✗
A GitHub webhook configured in the repository settings
Why it's wrong here
Webhooks are used to notify external services; GitHub Actions uses workflow triggers natively.
- ✗
A pull request review requirement
Why it's wrong here
Pull request reviews do not trigger deployments automatically.
- ✓
A workflow with an on.push trigger for the main branch
Why this is correct
Correct. The on.push event triggers the workflow on push to specified branches.
