GitHub Actions Certification — Question 5

Which command can you include in your workflow file to set the output parameter for an action?

Answer options

• A. echo "::debug::action_color=purple"
• B. echo "action_color=purple" >> $GITHUB_OUTPUT
• C. echo "action_color=purple" >> $GITHUB_ENV
• D. echo "::add-mask::$ACTION_COLOR"

Correct answer: B

Explanation

The correct answer is B because it uses the $GITHUB_OUTPUT environment variable to set the output parameter for an action in GitHub workflows. Option A is for debugging, option C sets environment variables instead of output parameters, and option D is used for masking sensitive data, not for setting outputs.
