Paloalto Networks Updated PSE-SWFW-Pro-24 Exam Questions and Answers by beatriz

The VM-Series tiering simplifies the product portfolio.

Why B is correct: The four-tier model (VE, VE-Lite, VE-Standard, VE-High) simplifies the selection process for customers by grouping VM-Series models based on performance and resource allocation. This makes it easier to choose the appropriate VM-Series instance based on their needs without having to navigate a long list of individual models.

Why A, C, and D are incorrect:

A. To obscure the supported hypervisor manufacturer into generic terms: The tiering is not related to obscuring hypervisor information. The documentation clearly states supported hypervisors.

C. To define the maximum limits for key criteria based on allocated memory: While memory is a factor in performance, the tiers are based on a broader set of resource allocations (vCPUs, memory, throughput) and features, not just memory.

D. To define the priority level of support customers expect when opening a TAC case: Support priority is based on support contracts, not the VM-Series tier.

Palo Alto Networks References: VM-Series datasheets and the VM-Series deployment guides explain the tiering model and its purpose of simplifying the portfolio.

The VM-Series plugin enables integration between Panorama and VM-Series firewalls.

Why C and D are correct:

C. To use Panorama to configure public cloud VM-Series firewall integrations, the VM-Series firewall plugin must be installed on Panorama: The plugin on Panorama provides the necessary functionality for managing VM-Series deployments in cloud environments.

D. The VM-Series firewall plugin on Panorama is not built in and must be installed to enable communication and manage the environment: The plugin is a separate installation on Panorama.

Why A and B are incorrect:

A. The installed VM-Series firewall plugin on the VM-Series firewall can only be upgraded or deleted: There is no VM-Series plugin installed on the VM-Series firewall itself. The plugin resides on Panorama.

B. The Panorama plugin must be installed on the VM-Series firewall to enable communication with Panorama: As stated above, the plugin is installed on Panorama, not on the VM-Series firewall. Communication is established through API calls.

‘QUESTION NO: 41Which three statements describe benefits of the memory scaling feature introduced in PAN-OS 10.2? (Choose three.)

A. Increased maximum throughput with additional memoryB. Increased maximum sessions with additional memoryC. Increased maximum number of Dynamic Address Groups with additional memoryD. Increased number of tags per IP address with additional memoryE. Increased maximum security rule count with additional memory

Answer: BCE

Memory scaling in PAN-OS 10.2 and later enhances capacity for certain functions.

Why B, C, and E are correct:

B. Increased maximum sessions with additional memory: More memory allows the firewall to maintain state for a larger number of concurrent sessions.

C. Increased maximum number of Dynamic Address Groups with additional memory: DAGs consume memory, so scaling memory allows for more DAGs.

E. Increased maximum security rule count with additional memory: More memory allows the firewall to store and process a larger number of security rules.

Why A and D are incorrect:

A. Increased maximum throughput with additional memory: Throughput is primarily related to CPU and network interface performance, not memory.

D. Increased number of tags per IP address with additional memory: The number of tags per IP is not directly tied to the memory scaling feature.

Palo Alto Networks References:

PAN-OS Release Notes for 10.2 and later: The release notes for PAN-OS versions introducing memory scaling explain the benefits in detail.

PAN-OS Administrator's Guide: The guide may also contain information about resource limits and the impact of memory scaling.

The release notes specifically mention the increased capacity for sessions, DAGs, and security rules as key benefits of memory scaling.

A. DNS sinkholing: DNS sinkholing redirects DNS requests for known malicious domains to a designated server, preventing users from accessing those sites. It doesn't inherently protect or hide an internal network in outbound flows. It's more of a preventative measure against accessing malicious external resources.

B. User-ID: User-ID maps network traffic to specific users, enabling policy enforcement based on user identity. It provides visibility and control but doesn't hide the internal network's addressing scheme in outbound connections.

C. App-ID: App-ID identifies applications traversing the network, allowing for application-based policy enforcement. Like User-ID, it doesn't mask the internal network's addressing.

D. NAT (Network Address Translation): NAT translates private IP addresses used within an internal network to a public IP address when traffic leaves the network. This effectively hides the internal IP addressing scheme from the external network. Outbound connections appear to originate from the public IP address of the NAT device (typically the firewall), thus protecting and hiding the internal network's structure.

Comprehensive and Detailed In-Depth Step-by-Step Explanation:The Cloud NGFW (Next-Generation Firewall) for AWS and Azure is a cloud-native security service that requires specific tools for management and configuration. According to the Palo Alto Networks Systems Engineer Professional - Software Firewall documentation, the following features are used to manage Cloud NGFW in these public cloud environments:

Palo Alto Networks Ansible playbooks (Option B): Ansible is an automation tool that Palo Alto Networks supports for managing Cloud NGFW deployments. Ansible playbooks use the XML API to automate configuration changes, policy enforcement, and monitoring for Cloud NGFW in AWS and Azure. This allows for scalable and repeatable management, reducing manual effort and ensuring consistency across deployments. The documentation highlights Ansible as a key automation tool for cloud-native firewalls, including Cloud NGFW.

Panorama (Option C): Panorama is Palo Alto Networks’ centralized management platform for firewalls, including Cloud NGFW. It provides a unified interface for managing policies, configurations, and logs for Cloud NGFW instances in AWS and Azure. Panorama integrates with the cloud provider’s APIs to ensure seamless management, offering features like policy push, logging, and reporting. This is a standard practice for customers requiring centralized control over their cloud security infrastructure.

Options A (Azure Firewall Portal) and D (AWS Firewall Manager) are incorrect. The Azure Firewall Portal is specific to Microsoft Azure’s native firewall and does not manage Palo Alto Networks Cloud NGFW. Similarly, AWS Firewall Manager is a native AWS service for managing AWS WAF and Shield, not Palo Alto Networks Cloud NGFW. These tools are not designed to integrate with or manage Palo Alto Networks’ cloud-native firewall solutions.
