Summary Formula vs. Conditional Highlighting - Dev 401 question

Question

Another Conflicting DEV 401 question...

Hiring managers at Universal containers would like a visual mechanism for determining review score outliers. Review scores are captured as a custom field on a custom Review object and can range from 1 to 10. Any review score that is >8 should be highlighted in green. Any review score that is < 4 should be highlighted in red.

1. Use custom summary formulas
2. Use matrix reports
3. Use conditional highlighting
4. Use charts
