PSE-Strata-Pro-24 Sample Questions Answers

To help a customer understand how Palo Alto Networks can bring value when adopting a Zero Trust architecture, the systems engineer must focus on understanding the customer's specific needs and explaining how the Zero Trust strategy aligns with their business goals. Here’s the detailed analysis of each option:

Option A: Ask the customer about their internal business flows, such as how their users interact with applications and data across the infrastructure

Understanding the customer's internal workflows and how their users interact with applications and data is a critical first step in Zero Trust. This information allows the systems engineer to identify potential security gaps and suggest tailored solutions.

This is correct.

Option B: Explain how Palo Alto Networks can place virtual NGFWs across the customer's network to ensure assets and traffic are seen and controlled

While placing NGFWs across the customer's network may be part of the implementation, this approach focuses on the product rather than the customer's strategy. Zero Trust is more about policies and architecture than specific product placement.

This is incorrect.

Option C: Use the Zero Trust Roadshow package to demonstrate to the customer how robust Palo Alto Networks capabilities are in meeting Zero Trust

While demonstrating capabilities is valuable during the later stages of engagement, the initial focus should be on understanding the customer's business requirements rather than showcasing products.

This is incorrect.

Option D: Ask the customer about their approach to Zero Trust, explaining that it is a strategy more than it is something they purchase

Zero Trust is not a product but a strategy that requires a shift in mindset. By discussing their approach, the systems engineer can identify whether the customer understands Zero Trust principles and guide them accordingly.

This is correct.

Single Pass Architecture (Answer C):

Palo Alto Networks firewalls useSingle Pass Architecture, meaning the firewall processes traffic once for all enabled security services.

This avoids duplicating inspection processes for multiple services like Threat Prevention, URL Filtering, and WildFire.

With a single traffic inspection pass, the firewall applies all security policies without degrading performance, even as additional CDSS subscriptions are enabled.

Management Data Plane Separation (Answer D):

TheManagement PlaneandData Planeare separated on Palo Alto Networks firewalls.

TheManagement Planehandles configuration, logging, and other administrative tasks, while theData Planefocuses solely on processing and forwarding traffic.

This architectural design ensures that enabling additional Cloud-Delivered Security Services does not impact throughput or compromise traffic handling efficiency.

Why Not Parallel Processing (Answer A):

While Parallel Processing is beneficial, it is not the main factor in maintaining consistent throughput as more services are enabled. TheSingle Pass Architectureis the key innovation here.

Why Not Advanced Routing Engine (Answer B):

The Advanced Routing Engine is not directly related to maintaining throughputwhen enabling CDSS subscriptions. It is more applicable to routing protocols and traffic engineering.

Management and Data Plane Overview

When preparing for a customer meeting, it’s important to understand their specific challenges and align solutions accordingly. The notes suggest that the customer is facing difficulties securing their cloud apps and remote users, which are core areas addressed by Palo Alto Networks’ Zero Trust and SASE solutions. However, jumping directly into a pitch or product demonstration without validating the customer's specific challenges may fail to build trust or fully address their needs.

Option A:Leading with a pre-structured pitch about Zero Trust principles may not resonate with the customer if their challenges are not fully understood first. The team needs to gather insights into the customer's security pain points before presenting a solution.

Option B (Correct):Discovery questionsare a critical step in the sales process, especially when addressing complex topics like Zero Trust. By designing targeted questions about the customer’s challenges with identity, devices, data, and access, the SE can identify specific pain points. These insights can then be used to tailor a Zero Trust strategy that directly addresses the customer’s concerns. This approach ensures the meeting is customer-focused and demonstrates that the SE understands their unique needs.

Option C:While a product demonstration of GlobalProtect, Prisma Access, and SaaS security is valuable, it should come after discovery. Presenting products prematurely may seem like a generic sales pitch and could fail to address the customer’s actual challenges.

Option D:Prisma SASEis an excellent solution for addressing cloud security and remote user challenges, but recommending it without first understanding the customer’s specific needs may undermine trust. This step should follow after discovery and validation of the customer’s pain points.

Examples of Discovery Questions:

What are your primary security challenges with remote users and cloud applications?

Are you currently able to enforce consistent security policies across your hybrid environment?

How do you handle identity verification and access control for remote users?

What level of visibility do you have into traffic to and from your cloud applications?

Aperimeter firewallis traditionally deployed at the boundary of a network to protect it from external threats. It provides a variety of protections, including blocking unauthorized access, inspecting traffic flows, and safeguarding sensitive resources. Here is how the options apply:

Option A (Correct):Perimeter firewalls providenetwork layer protectionby filtering and inspecting traffic entering or leaving the network at the outer edge. This is one of their primary roles.

Option B:Power utilization is not a functional or architectural aspect of a firewall and is irrelevant when describing the purpose of a perimeter firewall.

Option C:Securing east-west traffic is more aligned withdata center firewalls, whichmonitor lateral (east-west) movement of traffic within a virtualized or segmented environment. A perimeter firewall focuses on north-south traffic instead.

Option D (Correct):A perimeter firewall primarily securesnorth-south traffic, which refers to traffic entering and leaving the network. It ensures that inbound and outbound traffic adheres to security policies.

Option E (Correct):Perimeter firewalls play a critical role inguarding against external attacks, such as DDoS attacks, malicious IP traffic, and other unauthorized access attempts.

Policy Optimizer is a feature designed to help administrators improve the efficiency and effectiveness of security policies on Palo Alto Networks Next-Generation Firewalls (NGFWs). It focuses on identifying unused or overly permissive policies to streamline and optimize the configuration.

Why "Identify Security policy rules with unused applications" (Correct Answer C)?Policy Optimizer provides visibility into existing security policies and identifies rules that have unused or outdated applications. For example:

It can detect if a rule allows applications that are no longer in use.

It can identify rules with excessive permissions, enabling administrators to refine them for better security and performance.By addressing these issues, Policy Optimizer helps reduce the attack surface and improves the overall manageability of the firewall.

Why not "Recommend best practices on new policy creation" (Option A)?Policy Optimizer focuses on optimizingexisting policies, not creating new ones. While best practices can be applied during policy refinement, recommending new policy creation is notits purpose.

Why not "Show unused licenses for Cloud-Delivered Security Services (CDSS) subscriptions and firewalls" (Option B)?Policy Optimizer is not related to license management or tracking. Identifying unused licenses is outside the scope of its functionality.

Why not "Act as a migration tool to import policies from third-party vendors" (Option D)?Policy Optimizer does not function as a migration tool. While Palo Alto Networks offers tools for third-party firewall migration, this is separate from the Policy Optimizer feature.

The customer is seeking centralized policy management to reduce human error while maintaining compliance with their contractual obligations to AWS and Azure. Here's the evaluation of each option:

Option A: Cloud NGFWs at both CSPs; provide the customer a license for a Panorama virtual appliance from their CSP's marketplace of choice to centrally manage the systems

Cloud NGFW is a fully managed Next-Generation Firewall service by Palo Alto Networks, offered in AWS and Azure marketplaces. It integrates natively with the CSP infrastructure, making it a good fit for customers with existing CSP agreements.

Panorama, Palo Alto Networks' centralized management solution, can be deployed as a virtual appliance in the CSP marketplace of choice, enabling centralized policy management across all NGFWs.

This option addresses the customer's need for centralized management while leveraging their existing contracts with AWS and Azure.

This option is appropriate.

Option B: Cloud NGFWs in AWS and VM-Series firewall in Azure; the customer selects a PAYG licensing Panorama deployment in their CSP of choice

This option suggests using Cloud NGFW in AWS but VM-Series firewalls in Azure. While VM-Series is a flexible virtual firewall solution, it may not align with the customer’s stated preference for CSP-managed services like Cloud NGFW.

This option introduces a mix of solutions that could complicate centralized management and reduce operational efficiency.

This option is less appropriate.

Option C: VM-Series firewalls in both CSPs; manually built Panorama in the CSP of choice on a host of either type: Palo Alto Networks provides a license

VM-Series firewalls are well-suited for cloud deployments but require more manual configuration compared to Cloud NGFW.

Building a Panorama instance manually on a host increases operational overhead and does not leverage the customer’s existing CSP marketplaces.

This option is less aligned with the customer's needs.

Option D: VM-Series firewall and CN-Series firewall in both CSPs; provide the customer a private-offer Panorama virtual appliance from their CSP’s marketplace of choice to centrally manage the systems

This option introduces both VM-Series and CN-Series firewalls in both CSPs. While CN-Series firewalls are designed for Kubernetes environments, they may not be relevant if the customer does not specifically require container-level security.

Adding CN-Series firewalls may introduce unnecessary complexity and costs.

This option is not appropriate.

When configuring Advanced URL Filtering on a Palo Alto Networks firewall, the "Ransomware" category should be explicitly blocked to protect customers from URLs associated with ransomware activities. Ransomware URLs typically host malicious code or scripts designed to encrypt user data and demand a ransom. By blocking the "Ransomware" category, systems engineers can proactively prevent users from accessing such URLs.

Why "Ransomware" (Correct Answer A)?The "Ransomware" category is specifically curated by Palo Alto Networks to include URLs known to deliver ransomware or support ransomware operations. Blocking this category ensures that any URL categorized as part of this list will be inaccessible to end-users, significantly reducing the risk of ransomware attacks.

Why not "High Risk" (Option B)?While the "High Risk" category includes potentially malicious sites, it is broader and less targeted. It may not always block ransomware-specific URLs. "High Risk" includes a range of websites that are flagged based on factors like bad reputation or hosting malicious content in general. It is less focused than the "Ransomware" category.

Why not "Scanning Activity" (Option C)?The "Scanning Activity" category focuses on URLs used in vulnerability scans, automated probing, or reconnaissance by attackers. Although such activity could be a precursor to ransomware attacks, it does not directly block ransomware URLs.

Why not "Command and Control" (Option D)?The "Command and Control" category is designed to block URLs used by malware or compromised systems to communicate with their operators. While some ransomware may utilize command-and-control (C2) servers, blocking C2 URLs alone does not directly target ransomware URLs themselves.

By using the Advanced URL Filtering profile and blocking the "Ransomware" category, the firewall applies targeted controls to mitigate ransomware-specific threats.

Segregating a network into unique BGP environments requires the ability to configure separateeBGP autonomous systems(AS) within the NGFW. Palo Alto Networks firewalls support advanced BGP features, including the ability to create and manage multiple autonomous systems.

Why "It can be addressed by creating multiple eBGP autonomous systems" (Correct Answer B)?PAN-OS supports the configuration of multiple eBGP AS environments. By creating unique eBGP AS numbers for different parts of the network, traffic can be segregated and routed separately. This feature is commonly used in multi-tenant environments or networks requiring logical separation for administrative or policy reasons.

Each eBGP AS can maintain its own routing policies, neighbors, and traffic segmentation.

This approach allows the NGFW to address the customer’s need for segregated internal BGP environments.

Why not "It cannot be addressed because PAN-OS does not support it" (Option A)?This statement is incorrect because PAN-OS fully supports BGP, including eBGP, iBGP, and features like route reflectors, confederations, and autonomous systems.

Why not "It can be addressed with BGP confederations" (Option C)?While BGP confederations can logically group AS numbers within a single AS, they are generally used to simplify iBGP designs in very large-scale networks. They are not commonly used for segregating internal environments and are not required for the described use case.

Why not "It cannot be addressed because BGP must be fully meshed internally to work" (Option D)?Full mesh iBGP is only required in environments without route reflectors. The described scenario does not mention the need for iBGP full mesh; instead, it focuses on segregated environments, which can be achieved with eBGP.

Prisma Access (Answer A):

Strata Cloud Manager (SCM) and Panorama provide centralized visibility and management forPrisma Access, Palo Alto Networks’ cloud-delivered security platform for remote users and branch offices.

NGFW (Answer D):

Both SCM and Panorama are used to manage and monitorPalo Alto Networks Next-Generation Firewalls(NGFWs) deployed in on-premise, hybrid, or multi-cloud environments.

Prisma SD-WAN (Answer E):

SCM and Panorama integrate withPrisma SD-WANto manage branch connectivity and security, ensuring seamless operation in an SD-WAN environment.

Why Not B:

Prisma Cloudis a distinct platform designed for cloud-native security and is not directly managed through Strata Cloud Manager or Panorama.

Why Not C:

Cortex XSIAM(Extended Security Intelligence and Automation Management) is part of the Cortex platform and is not managed by SCM or Panorama.

Panorama Features and Benefits

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.

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. Unlikelegacy 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.

E. IoT Security

IoT Security is focused on discovering and managing IoT devices connected to the network. While this service uses machine learning for device behavior profiling and anomaly detection, it does not leverage inline machine learning for real-time traffic inspection. Instead, it operates at a more general level by providing visibility and identifying device risks.

Key Takeaways:

Enterprise DLP, Advanced URL Filtering, and Advanced Threat Prevention all rely on inline machine learning to provide real-time protection.

Advanced WildFire uses ML but not inline; its analysis is performed in the cloud.

IoT Security applies ML for device management rather than inline threat detection.

In this scenario, the company does not use on-premises Active Directory and manages devices with Entra ID and Jamf, which implies a cloud-native and modern management setup. Below is the evaluation of each option:

Option A: Captive portal

Captive portal is typically used in environments where identity mapping is needed for unmanaged devices or guest users. It provides a mechanism for users to authenticate themselves through a web interface.

However, in this case, the company is managing devices using Entra ID and Jamf, which means identity information can already be centralized through other means. Captive portal is not an ideal solution here.

This option is not appropriate.

Option B: User-ID agents configured for WMI client probing

WMI (Windows Management Instrumentation) client probing is a mechanism used to map IP addresses to usernames in a Windows environment. This approach is specific to on-premises Active Directory deployments and requires direct communication with Windows endpoints.

Since the company does not have an on-premises AD and is using Entra ID and Jamf, this method is not applicable.

This option is not appropriate.

Option C: GlobalProtect with an internal gateway deployment

GlobalProtect is Palo Alto Networks' VPN solution, which allows for secure remote access. It also supports identity-based mapping when deployed with internal gateways.

In this case, GlobalProtect with an internal gateway can serve as a mechanism to provide user and device visibility based on the managed devices connecting through the gateway.

This option is appropriate.

Option D: Cloud Identity Engine synchronized with Entra ID

The Cloud Identity Engine provides a cloud-based approach to synchronize identity information from identity providers like Entra ID (formerly Azure AD).

In a cloud-native environment with Entra ID and Jamf, the Cloud Identity Engine is a natural fit as it integrates seamlessly to provide identity visibility for applicationsand data.

This option is appropriate.

Zero Trust is a strategic framework for securing infrastructure and data by eliminating implicit trust and continuously validating every stage of digital interaction. Palo Alto Networks NGFWs are designed with native capabilities to align with Zero Trust principles, such as monitoring transactions, validating identities, and enforcing least-privilege access. The following narratives effectively address the customer’s question:

Option A:While emphasizing Zero Trust as an ideology is accurate, this response does not directly explain how Palo Alto Networks firewalls facilitate mapping of transactions. It provides context but is insufficient for addressing the technical aspect of the question.

Option B:Decryption and security protections are important for identifying malicious traffic, but they are not specific to mapping transactions within a Zero Trust framework. This response focuses on a subset of security functions rather than the broader concept of visibility and policy enforcement.

Option C (Correct):Placing the NGFW in the network providesvisibility into every traffic flowacross users, devices, and applications. This allows the firewall to map transactions and enforce Zero Trust principles such as segmenting networks, inspecting all traffic, and controlling access. With features like App-ID, User-ID, and Content-ID, the firewall provides granular insights into traffic flows, making it easier to identify and secure transactions.

Option D (Correct):Palo Alto Networks NGFWs usesecurity policies based on users, applications, and data objectsto align with Zero Trust principles. Instead of relying on IP addresses or ports, policies are enforced based on the application’s behavior, the identity of the user, and the sensitivity of the data involved. This mapping ensures that only authorized users can access specific resources, which is a cornerstone of Zero Trust.

Populating user-to-IP mappings is a critical function for enabling user-based policy enforcement in Palo Alto Networks firewalls. The following two methods are valid ways to populate these mappings:

Why "XML API" (Correct Answer A)?The XML API allows external systems to programmatically send user-to-IP mapping information to the firewall. This is a highly flexible method, particularly when user information is available from an external system that integrates via the API. This method is commonly used in environments where the mapping data is maintained in a centralized database or monitoring system.

Why "User-ID" (Correct Answer C)?User-ID is a core feature of Palo Alto Networks firewalls that allows for the dynamic identification of users and their corresponding IP addresses. User-ID agents can pull this data from various sources, such as Active Directory, Syslog servers, and more. This is one of the most common and reliable methods to maintain user-to-IP mappings.

Why not "Captive portal" (Option B)?Captive portal is a mechanism for authenticating users when they access the network. While it can indirectly contribute to user-to-IP mapping, it is not a direct method to populate these mappings. Instead, it prompts users to authenticate, after which User-ID handles the mapping.

Why not "SCP log ingestion" (Option D)?SCP (Secure Copy Protocol) is a file transfer protocol and does not have any functionality related to populating user-to-IP mappings. Log ingestion via SCP is not a valid way to map users to IP addresses.

Protecting web servers from advanced threats like SQL injection, command injection, XSS attacks, and IIS exploits requires a solution capable of deep packet inspection, behavioral analysis, and inline prevention of zero-day attacks. The most effective solution here isAdvanced Threat Prevention (ATP)combined withPAN-OS 11.x.

Why "Advanced Threat Prevention and PAN-OS 11.x" (Correct Answer B)?Advanced Threat Prevention (ATP) enhances traditional threat prevention by usinginline deep learning modelsto detect and block advanced zero-day threats, includingSQL injection, command injection, and XSS attacks. With PAN-OS 11.x, ATP extends its detection capabilities to detect unknown exploits without relying on signature-based methods. This functionality is critical for protecting web servers in scenarios where a dedicated WAF is unavailable.

ATP provides the following benefits:

Inline prevention of zero-day threats using deep learning models.

Real-time detection of attacks like SQL injection and XSS.

Enhanced protection for web server platforms like IIS.

Full integration with the Palo Alto Networks Next-Generation Firewall (NGFW).

Why not "Threat Prevention and PAN-OS 11.x" (Option A)?Threat Prevention relies primarily on signature-based detection for known threats. While it provides basic protection, it lacks the capability to block zero-day attacks using advanced methods like inline deep learning. For zero-day SQL injection and XSS attacks, Threat Prevention alone is insufficient.

Why not "Threat Prevention, Advanced URL Filtering, and PAN-OS 10.2 (and higher)" (Option C)?While this combination includes Advanced URL Filtering (useful for blocking malicious URLs associated with exploits), it still relies onThreat Prevention, which is signature-based. This combination does not provide the zero-day protection needed for advanced injection attacks or XSS vulnerabilities.

Why not "Advanced WildFire and PAN-OS 10.0 (and higher)" (Option D)?Advanced WildFire is focused on analyzing files and executables in a sandbox environment to identify malware. While it is excellent for identifying malware, it is not designed to provide inline prevention for web-based injection attacks or XSS exploits targeting web servers.
