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

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.

The problem provides several constraints and design requirements that must be carefully considered:

Bandwidth Requirement:

The customer needs an NGFW capable of handling a total throughput of 72 Gbps.

The PA-5445 is specifically designed for high-throughput environments and supports up to 81.3 Gbps Threat Prevention throughput (as per the latest hardware performance specifications). This ensures the throughput needs are fully met with some room for growth.

Interface Compatibility:

The customer mentions that their core switches support up to 40 Gbps interfaces. The design must include aggregate links to meet the overall bandwidth while aligning with the 40 Gbps interface limitations.

The PA-5445 supports 40Gbps QSFP+ interfaces, making it a suitable option for the hardware requirement.

No Change to IP Address Structure:

Since the customer cannot modify their IP address structure, deploying the NGFW in Layer-2 or Virtual Wire mode is ideal.

Virtual Wire mode allows the firewall to inspect traffic transparently between two Layer-2 devices without modifying the existing IP structure. Similarly, Layer-2 mode allows the firewall to behave like a switch at Layer-2 while still applying security policies.

Threat Prevention, DNS, and Sandboxing Requirements:

The customer requires advanced security features like Threat Prevention and potentially sandboxing (WildFire). The PA-5445 is equipped to handle these functionalities with its dedicated hardware-based architecture for content inspection and processing.

Aggregate Interface Groups:

The architecture should include aggregate interface groups to distribute traffic across multiple physical interfaces to support the high throughput requirement.

By aggregating 2 x 40Gbps interfaces on both sides of the path in Virtual Wire or Layer-2 mode, the design ensures sufficient bandwidth (up to 80 Gbps per side).

Why PA-5445 in Layer-2 or Virtual Wire mode is the Best Option:

Option A satisfies all the customer’s requirements:

The PA-5445 meets the 72 Gbps throughput requirement.

2 x 40 Gbps interfaces can be aggregated to handle traffic flow between the core switches and the NGFW.

Virtual Wire or Layer-2 mode preserves the IP address structure, while still allowing full threat prevention and DNS inspection capabilities.

The PA-5445 also supports sandboxing (WildFire) for advanced file-based threat detection.

Why Not Other Options:

Option B:

The PA-5430 is insufficient for the throughput requirement (72 Gbps). Its maximum Threat Prevention throughput is 60.3 Gbps, which does not provide the necessary capacity.

Option C:

While the PA-5445 is appropriate, deploying it in Layer-3 mode would require changes to the IP address structure, which the customer explicitly stated is not an option.

Option D:

The PA-5430 does not meet the throughput requirement. Although Layer-2 or Virtual Wire mode preserves the IP structure, the throughput capacity of the PA-5430 is a limiting factor.

Step 1: Understand the Requirement and Context

Customer Need: Segregate the internal network into unique BGP environments, suggesting multiple isolated or semi-isolated routing domains within a single organization.

BGP Basics:

BGP is a routing protocol used to exchange routing information between autonomous systems (ASes).

eBGP: External BGP, used between different ASes.

iBGP: Internal BGP, used within a single AS, typically requiring a full mesh of peers unless mitigated by techniques like confederations or route reflectors.

Palo Alto NGFW: Supports BGP on virtual routers (VRs) within PAN-OS, enabling advanced routing capabilities for Strata hardware firewalls (e.g., PA-Series).

Strata Cloud Manager (SCM) is Palo Alto Networks’ centralized cloud-based management platform for managing network security solutions, including Prisma Access and Prisma SD-WAN. SCM can also integrate with VM-Series firewalls for managing virtualized NGFW deployments.

Why A (Prisma SD-WAN) Is Correct

SCM is the management interface for Prisma SD-WAN, enabling centralized orchestration, monitoring, and configuration of SD-WAN deployments.

Why D (VM-Series NGFW) Is Correct

SCM supports managing VM-Series NGFWs, providing centralized visibility and control for virtualized firewall deployments in cloud or on-premises environments.

Why Other Options Are Incorrect

B (Prisma Cloud): Prisma Cloud is a separate product for securing workloads in public cloud environments. It is not managed via SCM.

C (Cortex XDR): Cortex XDR is a platform for endpoint detection and response (EDR). It is managed through its own console, not SCM.

The default configuration of a Palo Alto Networks NGFW includes a set of default security rules that determine how traffic is handled when no explicit rules are defined. Here's the explanation for each option:

Option A: Security profiles are applied to all policies by default, eliminating implicit trust of any data traversing the firewall

Security profiles (such as Antivirus, Anti-Spyware, and URL Filtering) are not applied to any policies by default. Administrators must explicitly apply them to security rules.

This statement is incorrect.

Option B: The default policy action for intrazone traffic is deny, eliminating implicit trust within a security zone

By default, traffic within the same zone (intrazone traffic) is allowed. For example, traffic between devices in the "trust" zone is permitted unless explicitly denied by an administrator.

This statement is incorrect.

Option C: The default policy action allows all traffic unless explicitly denied

Palo Alto Networks firewalls do not have an "allow all" default rule. Instead, they include a default "deny all" rule for interzone traffic and an implicit "allow" rule for intrazone traffic.

This statement is incorrect.

Option D: The default policy action for interzone traffic is deny, eliminating implicit trust between security zones

By default, traffic between different zones (interzone traffic) is denied. This aligns with the principle of zero trust, ensuring that no traffic is implicitly allowed between zones. Administrators must define explicit rules to allow interzone traffic.

This statement is correct.

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.

Palo Alto Networks AIOps for NGFW is a cloud-delivered service that leverages telemetry data and machine learning (ML) to provide proactive operational insights, best practice recommendations, and issue prevention.

Why "It is offered in two license tiers: a free version and a premium version" (Correct Answer B)?AIOps for NGFW is available in two tiers:

Free Tier: Provides basic operational insights and best practices at no additional cost.

Premium Tier: Offers advanced capabilities, such as AI-driven forecasts, proactive issue prevention, and enhanced ML-based recommendations.

Why "It uses telemetry data to forecast, preempt, or identify issues, and it uses machine learning (ML) to adjust and enhance the process" (Correct Answer C)?AIOps uses telemetry data from NGFWs to analyze operational trends, forecast potential problems, and recommend solutions before issues arise. ML continuously refines these insights by learning from real-world data, enhancing accuracy and effectiveness over time.

Why not "It is offered in two license tiers: a commercial edition and an enterprise edition" (Option A)?This is incorrect because the licensing model for AIOps is based on "free" and "premium" tiers, not "commercial" and "enterprise" editions.

Why not "It forwards log data to Advanced WildFire to anticipate, prevent, or identify issues, and it uses machine learning (ML) to refine and adapt to the process" (Option D)?AIOps does not rely on Advanced WildFire for its operation. Instead, it uses telemetry data directly from the NGFWs to perform operational and security analysis.

The PA-400 Series is the most cost-efficient Palo Alto Networks NGFW for small branch offices. Let’s analyze the options:

PA-400 Series (Recommended Option)

The PA-400 Series (PA-410, PA-415, etc.) is specifically designed for small to medium-sized branch offices with fewer than 50 users.

It provides all the necessary security features, including Advanced Threat Prevention, at a lower price point compared to higher-tier models.

It supports PAN-OS and Cloud-Delivered Security Services (CDSS), making it suitable for securing internet traffic at branch locations.

Why Other Options Are Incorrect

PA-200: The PA-200 is an older model and is no longer available. It lacks the performance and features needed for modern branch office security.

PA-500: The PA-500 is also an older model that is not as cost-efficient as the PA-400 Series.

PA-600: The PA-600 Series does not exist.

Key Takeaways:

For branch offices with fewer than 50 users, the PA-400 Series offers the best balance of cost and performance.

The CN-Series firewalls are Palo Alto Networks’ containerized Next-Generation Firewalls (NGFWs) designed to secure Kubernetes clusters. Unlike the Strata Hardware Firewalls (e.g., PA-Series), which are physical appliances, the CN-Series is a software-based solution deployed within containerized environments. The question focuses on the specific files used to deploy CN-Series firewalls in Kubernetes clusters. Based on Palo Alto Networks’ official documentation, the two correct files are PAN-CN-MGMT-CONFIGMAP and PAN-CN-MGMT. Below is a detailed explanation of why these files are essential, with references to CN-Series deployment processes (noting that Strata hardware documentation is not directly applicable here but is contextualized for clarity).

Step 1: Understanding CN-Series Deployment in Kubernetes

The CN-Series firewall consists of two primary components: the CN-MGMT (management plane) and the CN-NGFW (data plane). These components are deployed as containers in a Kubernetes cluster, orchestrated using YAML configuration files. The deployment process involves defining resources such as ConfigMaps, Pods, and Services to instantiate and manage the CN-Series components. The files listed in the question are Kubernetes manifests or configuration files used during this process.

CN-MGMT Role: The CN-MGMT container handles the management plane, providing configuration, logging, and policy enforcement for the CN-Series firewall. It requires a dedicated YAML file to define its deployment.

CN-NGFW Role: The CN-NGFW container handles the data plane, inspecting traffic within the Kubernetes cluster. It relies on configurations provided by CN-MGMT and additional networking setup (e.g., via CNI plugins).

ConfigMaps: Kubernetes ConfigMaps store configuration data separately from container images, making them critical for passing settings to CN-Series components.

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.

The customer’s question focuses on how Palo Alto Networks Strata Hardware Firewalls maintain throughput performance as more Cloud-Delivered Security Services (CDSS) subscriptions—such as Threat Prevention, URL Filtering, WildFire, DNS Security, and others—are enabled. Unlike traditional firewalls where enabling additional security features often degrades performance, Palo Alto Networks leverages its unique architecture to minimize this impact. The systems engineer (SE) should explain two key concepts—Parallel Processing and Single Pass Architecture—which are foundational to the firewall’s ability to sustain throughput. Below is a detailed explanation, verified against Palo Alto Networks documentation.

Step 1: Understanding Cloud-Delivered Security Services (CDSS) and Performance Concerns

CDSS subscriptions enhance the Strata Hardware Firewall’s capabilities by integrating cloud-based threat intelligence and advanced security features into PAN-OS. Examples include:

Threat Prevention: Blocks exploits, malware, and command-and-control traffic.

WildFire: Analyzes unknown files in the cloud for malware detection.

URL Filtering: Categorizes and controls web traffic.

Traditionally, enabling such services on other firewalls increases processing overhead, as each feature requires separate packet scans or additional hardware resources, leading to latency and throughput loss. Palo Alto Networks claims consistent performance due to its innovative design, rooted in the Single Pass Parallel Processing (SP3) architecture.

Advanced WildFire is Palo Alto Networks' cloud-based malware analysis and prevention solution. It determines whether files are malicious by executing them in a sandbox environment and observing their behavior. To address the customer's concern about the file categorization, the systems engineer must provide evidence of the file's behavior. Here’s the analysis of each option:

Option A: Review the threat logs for information to provide to the customer

Threat logs can provide a summary of events and verdicts for malicious files, but they do not include the detailed behavior analysis needed to convince the customer.

While reviewing the logs is helpful as a preliminary step, it does not provide the level of proof the customer needs.

This option is not sufficient on its own.

Option B: Use the WildFire Analysis Report in the log to show the customer the malicious actions the file took when it was detonated

WildFire generates an analysis report that includes details about the file's behavior during detonation in the sandbox, such as network activity, file modifications, process executions, and any indicators of compromise (IoCs).

This report provides concrete evidence to demonstrate why the file was flagged as malicious. It is the most accurate way to assure the customer that WildFire's decision was based on observed malicious actions.

This is the best option.

Option C: Open a TAG ticket for the customer and allow support engineers to determine the appropriate action

While opening a support ticket is a valid action for further analysis or appeal, it is not a direct way to assure the customer of the current WildFire verdict.

This option does not directly address the customer’s request for immediate proof.

This option is not ideal.

Option D: Do nothing because the customer will realize Advanced WildFire is right

This approach is dismissive of the customer's concerns and does not provide any evidence to support WildFire's decision.

This option is inappropriate.

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 is Advanced Threat Prevention (ATP) combined with PAN-OS 11.x.

Why "Advanced Threat Prevention and PAN-OS 11.x" (Correct Answer B)?Advanced Threat Prevention (ATP) enhances traditional threat prevention by using inline deep learning models to detect and block advanced zero-day threats, including SQL 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 on Threat 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.

Zero Trust principles revolve around minimizing trust in the network and verifying every interaction. To adopt Zero Trust, customers should start by gaining visibility and understanding the network and its transactions.

A. Understand which users, devices, infrastructure, applications, data, and services are part of the network or have access to it.

The first step in adopting Zero Trust is understanding the full scope of the network. Identifying users, devices, applications, and data is critical for building a comprehensive security strategy.

C. Map the transactions between users, applications, and data, then verify and inspect those transactions.

After identifying all assets, the next step is to map interactions and enforce verification and inspection of these transactions to ensure security.

Why Other Options Are Incorrect

B: Enabling CDSS subscriptions is important for protection but comes after foundational Zero Trust principles are established.

D: Implementing VM-Series NGFWs is part of enforcing Zero Trust, but it is not the first step. Visibility and understanding come first.

To secure and protect your traffic using CDSS, Cloud NGFW for AWS provides Palo Alto Networks protections such as:

App-ID. Based on patented Layer 7 traffic classification technology, the App-ID service allows you to see the applications on your network, learn how they work, observe their behavioral characteristics, and understand their relative risk. Cloud NGFW for AWS identifies applications and application functions via multiple techniques, including application signatures, decryption, protocol decoding, and heuristics. These capabilities determine the exact identity of applications traversing your network, including those attempting to evade detection by masquerading as legitimate traffic by hopping ports or using encryption.

Threat Prevention. The Palo Alto Networks Threat Prevention service protects your network by providing multiple layers of prevention to confront each phase of an attack. In addition to essential intrusion prevention service (IPS) capabilities, Threat Prevention possesses the unique ability to detect and block threats on any ports—rather than simply invoking signatures based on a limited set of predefined ports.

Advanced URL Filtering. This critical service built into Cloud NGFW for AWS stops unknown web-based attacks in real-time to prevent patient zero with the industry’s only ML-powered Advanced URL Filtering. Advanced URL Filtering combines the renowned Palo Alto Networks malicious URL database with the industry’s first real-time web protection engine so organizations can automatically and instantly detect and prevent new malicious and targeted web-based threats.

DNS. DNS Security gives you real-time protection, applying industry-first protections to disrupt attacks that use DNS. Tight integration with a Palo Alto Networks Next-Generation Firewall (NGFW) gives you automated protections, prevents attackers from bypassing security measures, and eliminates the need for independent tools or changes to DNS routing. DNS Security gives your organization a critical new control point to stop attacks.

WildFire. Palo Alto Networks Advanced WildFire® is the industry’s largest cloud-based malware prevention engine that protects organizations from highly evasive threats using patented machine learning detection engines, enabling automated protections across network, cloud, and endpoints. Advanced WildFire analyzes every unknown file for malicious intent and then distributes prevention in record time—60 times faster than the nearest competitor—to reduce the risk of patient zero.

The customer’s CIO highlights two key pain points: (1) the operations team lacks expertise to efficiently manage PAN-OS upgrades and support interactions, diverting focus from valuable tasks, and (2) the company lacked tools to monitor NGFW capacity, leading to a rushed upgrade. The goal is to recommend long-term solutions leveraging Palo Alto Networks’ offerings for Strata Hardware Firewalls. Options B and D—training and AIOps Premium within Strata Cloud Manager (SCM)—address these issues by enhancing team capability and providing proactive management tools. Below is a detailed explanation, verified against official documentation.

Step 1: Analyzing the Customer’s Challenges

Expertise Gap: The CIO notes that identifying issues and engaging support requires expertise the operations team doesn’t fully have or can’t prioritize. Upgrading PAN-OS on Strata NGFWs involves tasks like version compatibility checks, pre-upgrade validation, and troubleshooting, which demand familiarity with PAN-OS tools and processes.

Capacity Visibility: The rushed upgrade stemmed from not knowing the NGFWs were nearing capacity (e.g., CPU, memory, session limits), indicating a lack of monitoring or predictive analytics.

Long-term solutions must address both operational efficiency and proactive capacity management, aligning with Palo Alto Networks’ ecosystem for Strata firewalls.

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.

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 optimizing existing policies, not creating new ones. While best practices can be applied during policy refinement, recommending new policy creation is not its 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.
