PCNSE PCNSE Firewall Technology and Architecture 4 — Questions and Answers
Question 1: Which Palo Alto Networks feature enables the firewall to identify users even when they authenticate through a proxy or Citrix environment?
- GlobalProtect
- XML API User-ID agent
- Terminal Services Agent (TSA) (Correct answer)
- Captive Portal
Correct answer: Terminal Services Agent (TSA)
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)?
- Processing each security function in separate sequential passes
- Analyzing the packet once while simultaneously performing all security functions (Correct answer)
- Parallel processing of packets across multiple SPCs only
- Running App-ID and User-ID in parallel separate threads
Correct answer: Analyzing the packet once while simultaneously performing all security functions
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?
- Traffic is blocked permanently
- The user sees a page asking them to confirm they want to proceed (Correct answer)
- The session is silently allowed without logging
- The URL is quarantined for admin review
Correct answer: The user sees a page asking them to confirm they want to proceed
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?
- To override App-ID and classify traffic as a custom application (Correct answer)
- To allow all applications regardless of security rules
- To override Content-ID inspection for specific applications
- To change the application threat level
Correct answer: To override App-ID and classify traffic as a custom application
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'?
- Address objects define individual IPs/ranges/FQDNs; address groups combine multiple address objects (Correct answer)
- Address groups support FQDN while address objects do not
- Address objects are for IPv6 only; address groups are for IPv4
- There is no functional difference between them
Correct answer: Address objects define individual IPs/ranges/FQDNs; address groups combine multiple address objects
Address objects define a single IP, range, subnet, or FQDN, while address groups aggregate multiple address objects for simplified policy management.
Question 6: Which Palo Alto Networks security profile type inspects traffic for known exploit attempts and vulnerability attacks?
- Antivirus profile
- Anti-Spyware profile
- Vulnerability Protection profile (Correct answer)
- WildFire Analysis profile
Correct answer: Vulnerability Protection profile
Vulnerability Protection profiles detect and block exploit attempts targeting known software vulnerabilities using IPS signatures.
Question 7: What is the function of the Palo Alto Networks 'Decryption Broker' feature?
- It decrypts traffic and forwards plaintext copies to third-party security tools (Correct answer)
- It acts as a certificate authority for SSL inspection
- It brokers SSL certificates between clients and servers
- It manages decryption keys in a hardware security module
Correct answer: It decrypts traffic and forwards plaintext copies to third-party security tools
Decryption Broker allows the firewall to decrypt SSL/TLS traffic and forward the plaintext to third-party inline security appliances for additional inspection.
