Palo Alto Networks PSE-Strata-Pro-24 Palo Alto Networks Systems Engineer Professional - Hardware Firewall Exam Practice Test

Answer : A, B, D

To answer this question, let's analyze each Cloud-Delivered Security Service (CDSS) subscription and its role in inline machine learning (ML). Palo Alto Networks leverages inline ML capabilities across several of its subscriptions to provide real-time protection against advanced threats and reduce the need for manual intervention.

A . Enterprise DLP (Data Loss Prevention)

Enterprise DLP is a Cloud-Delivered Security Service that prevents sensitive data from being exposed. Inline machine learning is utilized to accurately identify and classify sensitive information in real-time, even when traditional data patterns or signatures fail to detect them. This service integrates seamlessly with Palo Alto firewalls to mitigate data exfiltration risks by understanding content as it passes through the firewall.

B . Advanced URL Filtering

Advanced URL Filtering uses inline machine learning to block malicious URLs in real-time. Unlike legacy URL filtering solutions, which rely on static databases, Palo Alto Networks' Advanced URL Filtering leverages ML to identify and stop new malicious URLs that have not yet been categorized in static databases. This proactive approach ensures that organizations are protected against emerging threats like phishing and malware-hosting websites.

C . Advanced WildFire

Advanced WildFire is a cloud-based sandboxing solution designed to detect and prevent zero-day malware. While Advanced WildFire is a critical part of Palo Alto Networks' security offerings, it primarily uses static and dynamic analysis rather than inline machine learning. The ML-based analysis in Advanced WildFire happens after a file is sent to the cloud for processing, rather than inline, so it does not qualify under this question's scope.

D . Advanced Threat Prevention

Advanced Threat Prevention (ATP) uses inline machine learning to analyze traffic in real-time and block sophisticated threats such as unknown command-and-control (C2) traffic. This service replaces the traditional Intrusion Prevention System (IPS) approach by actively analyzing network traffic and blocking malicious payloads inline. The inline ML capabilities ensure ATP can detect and block threats that rely on obfuscation and evasion techniques.

User-ID is a feature in PAN-OS that maps IP addresses to usernames by integrating with various directory services (e.g., Active Directory). User-ID can be implemented through agents provided by Palo Alto Networks. Here's how each option applies:

Option A: Integrated agent

The integrated User-ID agent is built into PAN-OS and does not require an external agent installation. It is configured directly on the firewall and integrates with directory services to retrieve user information.

This is correct.

Option B: GlobalProtect agent

GlobalProtect is Palo Alto Networks' VPN solution and does not function as a User-ID agent. While it can be used to authenticate users and provide visibility, it is not categorized as a User-ID agent.

This is incorrect.

Option C: Windows-based agent

The Windows-based User-ID agent is a standalone agent installed on a Windows server. It collects user mapping information from directory services and sends it to the firewall.

This is correct.

Option D: Cloud Identity Engine (CIE)

The Cloud Identity Engine provides identity services in a cloud-native manner but is not a User-ID agent. It synchronizes with identity providers like Azure AD and Okta.

This is incorrect.

Answer : B

SASE (Secure Access Service Edge) is a cloud-based solution that combines networking and security capabilities to address modern enterprise needs. However, there are scenarios where an on-premises solution is more appropriate.

A . High growth phase with existing and planned mergers, and with acquisitions being integrated.

This scenario typically favors a SASE solution since it provides flexible, scalable, and centralized security that is ideal for integrating newly acquired businesses.

B . Most employees and applications in close physical proximity in a geographic region.

This scenario supports the choice of an on-premises solution. When employees and applications are concentrated in a single geographic region, traditional on-premises firewalls and centralized security appliances provide cost-effective and efficient protection without the need for distributed, cloud-based infrastructure.

C . Hybrid work and cloud adoption at various locations that have different requirements per site.

This scenario aligns with a SASE solution. Hybrid work and varying site requirements are better addressed by SASE's ability to provide consistent security policies regardless of location.

D . The need to enable business to securely expand its geographical footprint.

Expanding into new geographic areas benefits from the scalability and flexibility of a SASE solution, which can deliver consistent security globally without requiring physical appliances at each location.

Key Takeaways:

On-premises solutions are ideal for geographically concentrated networks with minimal cloud adoption.

SASE is better suited for hybrid work, cloud adoption, and distributed networks.

On-Premises vs. SASE Deployment Guide

Answer : A

To address the MSSP's requirement for logically separated BGP peering setups while efficiently managing standard routing rules and updates, Palo Alto Networks offers the Advanced Routing Engine introduced in PAN-OS 11.0. The Advanced Routing Engine enhances routing capabilities, including support for logical routers, which is critical in this scenario.

Why A is Correct

Logical routers enable the MSSP to create isolated BGP peering configurations for each customer.

The Advanced Routing Engine allows the MSSP to share standard routing profiles (such as filters, policies, or maps) across logical routers, simplifying the deployment and maintenance of routing configurations.

This approach ensures scalability, as each logical router can handle the unique needs of a customer while leveraging shared routing rules.

Why Other Options Are Incorrect

B: While using APIs to automate deployment is beneficial, it does not solve the need for logically separated BGP peering setups. Logical routers provide this separation natively.

C: While virtual routers in PAN-OS can separate BGP peering setups, they do not support the efficient sharing of standard routing rules and profiles across multiple routers.

D: Virtual systems (vsys) are used to segregate administrative domains, not routing configurations. Vsys is not the appropriate solution for managing BGP peering setups across multiple customers.

Key Takeaways:

PAN-OS Advanced Routing Engine with logical routers simplifies BGP peering management for MSSPs.

Logical routers provide the separation required for customer environments while enabling shared configuration profiles.

Answer : A

A . Discuss the PAN-OS Policy Optimizer feature as a means to safely migrate port-based rules to application-based rules.

PAN-OS includes the Policy Optimizer tool, which helps migrate legacy port-based rules to application-based policies incrementally and safely. This tool identifies unused, redundant, or overly permissive rules and suggests optimized policies based on actual traffic patterns.

Why Other Options Are Incorrect

B: The migration wizard does not automatically convert port-based rules to application-based rules. Migration must be carefully planned and executed using tools like the Policy Optimizer.

C: Running two firewalls in parallel adds unnecessary complexity and is not a best practice for migration.

D: While port-based rules are supported, relying on them defeats the purpose of transitioning to application-based security.

North-south traffic refers to the flow of data in and out of a network, typically between internal resources and the internet. To secure this type of traffic, Palo Alto Networks recommends specific CDSS subscriptions in addition to DNS Security:

A . SaaS Security

SaaS Security is designed for monitoring and securing SaaS application usage but is not essential for handling typical north-south traffic.

B . Advanced WildFire

Advanced WildFire provides cloud-based malware analysis and sandboxing to detect and block zero-day threats. It is a critical component for securing north-south traffic against advanced malware.

C . Enterprise DLP

Enterprise DLP focuses on data loss prevention, primarily for protecting sensitive data. While important, it is not a minimum recommendation for securing north-south traffic.

D . Advanced Threat Prevention

Advanced Threat Prevention (ATP) replaces traditional IPS and provides inline detection and prevention of evasive threats in north-south traffic. It is a crucial recommendation for protecting against sophisticated threats.

E . Advanced URL Filtering

Advanced URL Filtering prevents access to malicious or harmful URLs. It complements DNS Security to provide comprehensive web protection for north-south traffic.

Key Takeaways:

Advanced WildFire, Advanced Threat Prevention, and Advanced URL Filtering are minimum recommendations for NGFWs handling north-south traffic, alongside DNS Security.

SaaS Security and Enterprise DLP, while valuable, are not minimum requirements for this use case.

Cloud-Delivered Security Services

Answer : C

Zero-day malware attacks are sophisticated threats that exploit previously unknown vulnerabilities or malware signatures. To provide protection against such attacks, the appropriate Cloud-Delivered Security Service subscription must be included.

Why 'Advanced WildFire' (Correct Answer C)?

Advanced WildFire is Palo Alto Networks' sandboxing solution that identifies and prevents zero-day malware. It uses machine learning, dynamic analysis, and static analysis to detect unknown malware in real time.

Files and executables are analyzed in the cloud-based sandbox, and protections are shared globally within minutes.

Advanced WildFire specifically addresses zero-day threats by dynamically analyzing suspicious files and generating new signatures.

Why not 'AI Access Security' (Option A)?

AI Access Security is designed to secure SaaS applications by monitoring and enforcing data protection and compliance. While useful for SaaS security, it does not focus on detecting or preventing zero-day malware.

Why not 'Advanced Threat Prevention' (Option B)?

Advanced Threat Prevention (ATP) focuses on detecting zero-day exploits (e.g., SQL injection, buffer overflows) using inline deep learning but is not specifically designed to analyze and prevent zero-day malware. ATP complements Advanced WildFire, but WildFire is the primary solution for malware detection.

Why not 'App-ID' (Option D)?

App-ID identifies and controls applications on the network. While it improves visibility and security posture, it does not address zero-day malware detection or prevention.
