An administrator needs to create a Security policy rule that matches DNS traffic sourced from either the LAN or VPN zones, destined for the DMZ or Untrust zones.
The administrator does not want to match traffic where the source and destination zones are LAN, and also does not want to match traffic where the source and destination zones are VPN.
Which Security policy rule type should they use?
The correct answer is Interzone. Since the administrator does not want to match traffic where the source and destination zones are the same (LAN to LAN or VPN to VPN), they need to focus on traffic between different zones. Interzone rules are designed to match traffic that traverses between different zones, which fits the requirement of matching traffic sourced from either the LAN or VPN zones and destined for DMZ or Untrust zones.
