What does Zscaler Advanced Firewall support that Zscaler Standard Firewall does not?

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.
