Which two options does the firewall use to dynamically populate address group members? (Choose two.)
A dynamic address group populates its members dynamically using look ups for tags and tag-based filters. Tags are metadata elements or attribute-value pairs that are registered for each IP address. Tag-based filters use logical and and or operators to match the tags and determine the membership of the dynamic address group. For example, you can create a dynamic address group that includes all IP addresses that have the tags ''web-server'' and ''linux''. You can also use static tags as part of the filter criteria.Reference:Policy Object: Address Groups,Use Dynamic Address Groups in Policy,Statics vs. Dynamic Address Objects Groups
Which feature must be configured to enable a data plane interface to submit DNS queries originated from the firewall on behalf of the control plane?
By default, the firewall uses the management (MGT) interface to access external services, such as DNS servers, external authentication servers, Palo Alto Netw orks services such as soft ware, URL updates, licenses, and AutoFocus. An alternative to using the MGT interface is configuring a data port (a standard interface) to access these services. The path from the interface to th e service on a server is aservice route.

The WebUI on the same interface can be accessed by going to the interface's IP address using https on port 4443. The port for WebUI management is changed because the tcp/443 socket used by GlobalProtect takes precedence
