PCNSE PCNSE Firewall Technology and Architecture 4

Question 1

Which Palo Alto Networks feature enables the firewall to identify users even when they authenticate through a proxy or Citrix environment?

Accepted Answer

Terminal Services Agent (TSA)

Answer

The Terminal Services Agent maps individual user traffic on shared-IP environments like Citrix or RDS by tracking port ranges assigned to each user.

Question 2

In Palo Alto Networks firewall, what is 'single-pass parallel processing' (SP3)?

Accepted Answer

Analyzing the packet once while simultaneously performing all security functions

Answer

SP3 architecture analyzes network traffic in a single pass, simultaneously applying App-ID, User-ID, Content-ID, and policy enforcement without multiple scanning passes.

Question 3

When using Palo Alto Networks URL Filtering with the 'continue' action for a URL category, what happens?

Accepted Answer

The user sees a page asking them to confirm they want to proceed

Answer

The 'continue' action presents the user with a response page requiring them to click through to acknowledge the policy before accessing the site.

Question 4

What is the purpose of Palo Alto Networks 'Application Override' policy?

Accepted Answer

To override App-ID and classify traffic as a custom application

Answer

Application Override policies force the firewall to classify traffic as a specified custom application, bypassing App-ID's standard identification mechanism.

Question 5

In Palo Alto Networks firewalls, what is the difference between an 'address object' and an 'address group'?

Accepted Answer

Address objects define individual IPs/ranges/FQDNs; address groups combine multiple address objects

Answer

Address objects define a single IP, range, subnet, or FQDN, while address groups aggregate multiple address objects for simplified policy management.
