Advanced Firewall extends standard firewall capabilities with DNS Tunnel and DNS Application Control. Those controls detect and manage DNS-based tunneling, command channels, or application behavior that simple network-service rules cannot adequately control. Option D (DNS Tunnel and DNS Application Control) is correct because DNS Tunnel and DNS Application Control are advanced firewall features.
Why the other options are incorrect:
A. Destination NAT: Destination NAT rewrites destination addresses. The tested Advanced Firewall value is DNS tunnel/application control, not NAT translation.
B. FQDN Filtering with wildcard: FQDN filtering applies rules to domain names, including wildcard domain patterns where supported.
C. DNS Dashboards, Insights and Logs: DNS resolves names to IP addresses; it is a support service, not an access protocol or scoring engine by itself.
