Palo Alto Networks PSE-Strata-Pro-24 Exam Dumps

Palo Alto Networks Next-Generation Firewalls (NGFWs) provide robust security features across a variety of use cases. Let's analyze each option:

A . Code-embedded NGFWs provide enhanced IoT security by allowing PAN-OS code to be run on devices that do not support embedded VM images.

This statement is incorrect. NGFWs do not operate as 'code-embedded' solutions for IoT devices. Instead, they protect IoT devices through advanced threat prevention, device identification, and segmentation capabilities.

B . Serverless NGFW code security provides public cloud security for code-only deployments that do not leverage VM instances or containerized services.

This is not a valid use case. Palo Alto NGFWs provide security for public cloud environments using VM-series firewalls, CN-series (containerized firewalls), and Prisma Cloud for securing serverless architectures. NGFWs do not operate in 'code-only' environments.

C . IT/OT segmentation firewalls allow operational technology (OT) resources in plant networks to securely interface with IT resources in the corporate network.

This is a valid use case. Palo Alto NGFWs are widely used in industrial environments to provide IT/OT segmentation, ensuring that operational technology systems in plants or manufacturing facilities can securely communicate with IT networks while protecting against cross-segment threats. Features like App-ID, User-ID, and Threat Prevention are leveraged for this segmentation.

D . PAN-OS GlobalProtect gateways allow companies to run malware and exploit prevention modules on their endpoints without installing endpoint agents.

This is incorrect. GlobalProtect gateways provide secure remote access to corporate networks and extend the NGFW's threat prevention capabilities to endpoints, but endpoint agents are required to enforce malware and exploit prevention modules.

Key Takeaways:

IT/OT segmentation with NGFWs is a real and critical use case in industries like manufacturing and utilities.

The other options describe features or scenarios that are not applicable or valid for NGFWs.

Palo Alto Networks NGFW Use Cases

Industrial Security with NGFWs

Prisma Access (Answer A):

Strata Cloud Manager (SCM) and Panorama provide centralized visibility and management for Prisma 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 monitor Palo Alto Networks Next-Generation Firewalls (NGFWs) deployed in on-premise, hybrid, or multi-cloud environments.

Prisma SD-WAN (Answer E):

SCM and Panorama integrate with Prisma SD-WAN to manage branch connectivity and security, ensuring seamless operation in an SD-WAN environment.

Why Not B:

Prisma Cloud is 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

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.

A large deployment of 500 firewalls requires a scalable, centralized logging and reporting infrastructure. Here's the analysis of each option:

Option A: Combine Panorama for firewall management with Palo Alto Networks' cloud-based Strata Logging Service to offer scalability for the company's logging and reporting infrastructure

The Strata Logging Service (or Cortex Data Lake) is a cloud-based solution that offers massive scalability for logging and reporting. Combined with Panorama, it allows for centralized log collection, analysis, and policy management without the need for extensive on-premises infrastructure.

This approach is ideal for large-scale environments like the one described in the scenario, as it ensures cost-effectiveness and scalability.

This is the correct recommendation.

Option B: Use Panorama for firewall management and to transfer logs from the 500 firewalls directly to a third-party SIEM for centralized logging and reporting

While third-party SIEM solutions can be integrated with Palo Alto Networks NGFWs, directly transferring logs from 500 firewalls to a SIEM can lead to bottlenecks and scalability issues. Furthermore, relying on third-party solutions may not provide the same level of native integration as the Strata Logging Service.

This is not the ideal recommendation.

Option C: Highlight the efficiency of PAN-OS, which employs AI to automatically extract critical logs and generate daily executive reports, and confirm that the purchase of 500 NGFWs is sufficient

While PAN-OS provides AI-driven insights and reporting, this option does not address the requirement for centralized logging and reporting. It also dismisses the need for additional infrastructure to handle logs from 500 firewalls.

This is incorrect.

Option D: Deploy a pair of M-1000 log collectors in the customer data center, and route logs from all 500 firewalls to the log collectors for centralized logging and reporting

The M-1000 appliance is an on-premises log collector, but it has limitations in terms of scalability and storage capacity when compared to cloud-based options like the Strata Logging Service. Deploying only two M-1000 log collectors for 500 firewalls would result in potential performance and storage challenges.

This is not the best recommendation.

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.
