Palo Alto firewalls can gather User-ID mappings from proxies via Syslog (Option B), parsing log messages with user-IP data, and XFF Headers (Option D), extracting user info from HTTP headers (X-Forwarded-For) if the proxy supports it.

Option A (Client Probing) queries clients, not proxies. Option C (Server Monitoring) targets servers like AD, not proxies. Documentation lists these methods for proxy integration.

For HIP match logs to be visible on the data center firewall, the following conditions must be met:

HIP profiles added to security rules: HIP profiles must be applied to security rules on the data center firewall to enforce access restrictions based on the received HIP reports. If the HIP profiles are not associated with the security rules, the firewall will not evaluate traffic against these profiles, and consequently, no HIP match logs will be generated.

User-ID enabled on the incoming zone: User-ID must be enabled on the zone where the users are located in the data center firewall. The User-ID feature is responsible for mapping IP addresses to user names, which is critical for applying policies based on user identity and, by extension, for HIP-based policy enforcement.

The other options (A and D) are related to logging and log forwarding but would not directly impact the generation or visibility of HIP match logs on the data center firewall itself.

When dealing with a false positive, particularly for a spyware threat detected through DNS queries (as indicated by the category "dns-c2"), the correct course of action involves creating an exception in the Anti-Spyware profile, not the Vulnerability Protection profile. This is because the Anti-Spyware profile in Palo Alto Networks firewalls is designed to detect and block spyware threats, which can include command and control (C2) activities often signaled by DNS queries.

The steps to configure an exception for this specific spyware signature (threat ID: 1000011111) are as follows:

Navigate to Objects > Security Profiles > Anti-Spyware. This is where all the Anti-Spyware profiles are listed.

Select the related Anti-Spyware profile that is currently applied to the security policy which is generating the false positive.

Within the profile, go to the DNS Exceptions tab. This tab allows you to specify exceptions based on DNS signatures.

Search for the related threat ID (in this case, 1000011111) and click enable to create an exception for it. By doing this, you instruct the firewall to bypass the detection for this specific signature, effectively treating it as a false positive.

Commit the changes to make the exception active.

By following these steps, the administrator can effectively address the false positive without disabling the overall spyware protection capabilities of the firewall.

The standalone User-ID agent (Option C) offloads user-to-IP mapping to an external server, reducing the firewall’s management CPU usage compared to the integrated agent, which runs on the firewall. Option A is false; neither requires domain membership. Option B is incorrect; the integrated agent uses more resources. Option D is false; the standalone agent can run on any server. The original answer (B) was incorrect, contributing to the 83% Core Concepts score.
