Option B enables the required traffic by allowing SSL and web-browsing from UNTRUST to DMZ, denying SSH from UNTRUST to DMZ, allowing MYSQL from DMZ to SERVER, and allowing SSH from SERVER to DMZ. Option A allows SSH from UNTRUST to DMZ, which is not required. Option C denies all the required traffic. Option D denies all traffic from UNTRUST to TRUST, which is irrelevant to the question

Palo Alto Networks firewalls can map IP addresses to usernames using various methods, such as User-ID agents, Captive Portal, GlobalProtect, XML API, and HTTP headers. These methods allow the firewall to enforce security policies based on user identity, rather than just IP address. Some of these methods are:

• Using the XML API: The XML API allows external systems to send user mapping information to the firewall using HTTPS requests. The firewall can then use this information to identify the users behind the IP addresses and apply the appropriate policies1.
• A user connecting into a GlobalProtect gateway using a GlobalProtect Agent: GlobalProtect provides secure remote access to the network by establishing a VPN tunnel between the user’s device and the firewall. When a user connects to a GlobalProtect gateway using a GlobalProtect agent, the firewall can authenticate the user and map the user’s IP address to the username1.
• Usernames inserted inside HTTP Headers: The firewall can also extract usernames from HTTP headers in web traffic. This method requires the web server or proxy server to insert the username into a custom HTTP header that the firewall can read. The firewall can then use this information to map the IP address to the username1.

The NAT Target tab is a table that allows you to specify the target firewalls or device groups for each NAT policy rule on Panorama. This tab is available only on Panorama and not on individual firewalls. The NAT Target tab enables you to create a single NAT policy rulebase on Panorama and then selectively push the rules to the firewalls or device groups that require them. This reduces the complexity and duplication of managing NAT policies across multiple firewalls1. References: NAT Target Tab, NAT Policy Overview, NPTv6 Overview, Updated Certifications for PAN-OS 10.1.
