# Which domain does the Cilium toFQDNs pattern *.example.com match?

Cilium, Easy (Beginner), Policies. https://k8wiz.com/uquiz/which-domain-does-the-cilium-tofqdns-pattern-examplecom-match

- A. example.com
- B. a.b.example.com
- C. example.com.evil.io
- D. api.example.com

**Answer:** api.example.com

**Explanation:** In a Cilium matchPattern, * matches any characters except a dot, so *.example.com covers exactly one extra label. It doesn't match the bare example.com or a.b.example.com. The **. prefix, as in **.example.com, matches subdomains at any depth.
