PCNSE PCNSE Advanced Threat Prevention 4 — Questions and Answers
Question 1: Which feature in Advanced Threat Prevention provides protection against evasive C2 traffic that uses encrypted or obfuscated channels?
- App-ID
- Advanced C2 Prevention using ML models via Inline Cloud Analysis (Correct answer)
- DNS Security with passive monitoring
- QoS traffic shaping
Correct answer: Advanced C2 Prevention using ML models via Inline Cloud Analysis
Advanced C2 Prevention uses ML-based Inline Cloud Analysis to detect encrypted or obfuscated command-and-control channels that evade signature-based detection.
Question 2: What happens when a firewall running WildFire receives a 'Phishing' verdict for a submitted URL?
- The firewall immediately drops all traffic from the submitting user
- A phishing signature is generated and distributed to WildFire subscribers (Correct answer)
- The URL is added to the PAN-DB benign list
- The session is marked for QoS deprioritization
Correct answer: A phishing signature is generated and distributed to WildFire subscribers
A Phishing verdict causes WildFire to generate and distribute a new anti-phishing signature to all WildFire-subscribed firewalls.
Question 3: An administrator notices that a Vulnerability Protection profile is consuming high CPU on the firewall. Which action can reduce resource usage without eliminating protection?
- Set all signatures to 'Alert' action
- Enable only 'critical' and 'high' severity signatures in the profile (Correct answer)
- Disable App-ID on the security policy
- Switch WildFire to a private cloud appliance
Correct answer: Enable only 'critical' and 'high' severity signatures in the profile
Limiting active signatures to critical and high severity reduces the number of patterns inspected per session, lowering CPU overhead while maintaining coverage for the most dangerous threats.
Question 4: Which PAN-OS feature allows administrators to view the behavioral activity of a malware sample analyzed by WildFire, such as file system changes and network connections?
- Security policy hit count dashboard
- WildFire Analysis Report (Correct answer)
- Threat log detail view
- Application statistics report
Correct answer: WildFire Analysis Report
The WildFire Analysis Report provides a detailed behavioral breakdown of a submitted sample, including process activity, registry changes, and network communication.
Question 5: A company's compliance policy prohibits sending any internal files to the cloud. Which WildFire deployment mode meets this requirement?
- Public WildFire cloud with file hashing only
- WildFire private cloud using a WF-500 appliance (Correct answer)
- Panorama-based WildFire integration
- WildFire hybrid mode sending only PE files externally
Correct answer: WildFire private cloud using a WF-500 appliance
The WF-500 private cloud appliance performs all sandboxing on-premises so no file content leaves the organization's network.
Question 6: When applying a Security Profile Group to a security policy rule, which profiles are typically bundled together for complete threat prevention coverage?
- URL Filtering, QoS, and NAT profiles
- Antivirus, Anti-Spyware, Vulnerability Protection, URL Filtering, File Blocking, and WildFire Analysis (Correct answer)
- Authentication, Decryption, and DoS Protection profiles
- Data Filtering and Zone Protection profiles only
Correct answer: Antivirus, Anti-Spyware, Vulnerability Protection, URL Filtering, File Blocking, and WildFire Analysis
A complete Threat Prevention profile group combines Antivirus, Anti-Spyware, Vulnerability Protection, URL Filtering, File Blocking, and WildFire Analysis for layered coverage.
Question 7: What is the function of 'Data Filtering' profiles in the context of Threat Prevention on PAN-OS?
- They block executable files from traversing the firewall
- They detect and control the transmission of sensitive data patterns such as credit card numbers or SSNs (Correct answer)
- They filter DNS responses to remove malicious records
- They limit the file size submitted to WildFire for analysis
Correct answer: They detect and control the transmission of sensitive data patterns such as credit card numbers or SSNs
Data Filtering profiles inspect content for predefined or custom data patterns (e.g., PII) and can alert or block transfers containing sensitive information.
