Paloalto Networks Updated PCNSE Exam Questions and Answers by aysha

A transparent proxy operates by intercepting traffic without client configuration, typically redirecting HTTP (port 80) or HTTPS (port 443) to a proxy port on the firewall. In Palo Alto Networks NGFWs, when configuring a NAT rule for a transparent proxy, the standard translated port is 8080 (Option C), commonly used for proxy services. This port is where the firewall redirects client traffic for processing (e.g., URL filtering or decryption) before forwarding it to the destination.

Option A (80) is the original HTTP port, not a proxy port. Option B (443) is for HTTPS, not transparent proxy redirection. Option D (4443) is non-standard and unrelated. Documentation and best practices confirm 8080 for this use case.

But this is valid only for overlapping configuration" "You need to be careful, what is actually defined in the template. For example - if you decide to enable HA in the template, but after that you decide to not push it with template and just disable it again (remove the check from the "Enable HA" checkbox). This still will be part of the template, because now your template is explicitely defining HA disabled. If you made a change in the template, and later decide that you don't want to control this setting with template, you need to revert the config by clicking the green bar next to the changed value"

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.
