Which two are requirements for URL Analysis?

The NSX Edge nodes require access to the Internet to download category and reputation definitions, and a layer 7 gateway firewall rule must be configured on the tier-1 gateway uplink to capture DNS traffic. This will allow the URL Analysis service to analyze incoming DNS traffic and block malicious requests. For more information, please see this VMware Documentation article[1], which explains how to configure URL Analysis on NSX.
