Palo Alto Networks Systems Engineer Professional - Hardware Firewall PSE-Strata-Pro-24 Exam Questions with Experts Answers Updated Recently

Panorama is Palo Alto Networks’ centralized management solution for managing multiple firewalls. It supports multiple deployment options to suit different infrastructure needs. The valid deployment options are as follows:

Why "As a virtual machine (ESXi, Hyper-V, KVM)" (Correct Answer A)?Panorama can be deployed as a virtual machine on hypervisors like VMware ESXi, Microsoft Hyper-V, and KVM. This is a common option for organizations that already utilize virtualized infrastructure.

Why "With a cloud service provider (AWS, Azure, GCP)" (Correct Answer B)?Panorama is available for deployment in the public cloud on platforms like AWS, Microsoft Azure, and Google Cloud Platform. This allows organizations to centrally manage firewalls deployed in cloud environments.

Why "As a dedicated hardware appliance (M-100, M-200, M-500, M-600)" (Correct Answer E)?Panorama is available as a dedicated hardware appliance with different models (M-100, M-200, M-500, M-600) to cater to various performance and scalability requirements. This is ideal for organizations that prefer physical appliances.

Why not "As a container (Docker, Kubernetes, OpenShift)" (Option C)?Panorama is not currently supported as a containerized deployment. Containers are more commonly used for lightweight and ephemeral services, whereas Panorama requires a robust and persistent deployment model.

Why not "On a Raspberry Pi (Model 4, Model 400, Model 5)" (Option D)?Panorama cannot be deployed on low-powered hardware like Raspberry Pi. The system requirements for Panorama far exceed the capabilities of Raspberry Pi hardware.

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.

When sizing a Palo Alto Networks NGFW appliance, it's crucial to consider variables that affect its performance and capacity. These include the network's traffic characteristics, application requirements, and expected workloads. Below is the analysis of each option:

Option A: Connections per second

Connections per second (CPS) is a critical metric for determining how many new sessions the firewall can handle per second. High CPS requirements are common in environments with high traffic turnover, such as web servers or applications with frequent session terminations and creations.

This is an important sizing variable.

Option B: Max sessions

Max sessions represent the total number of concurrent sessions the firewall can support. For environments with a large number of users or devices, this metric is critical to prevent session exhaustion.

This is an important sizing variable.

Option C: Packet replication

Packet replication is used in certain configurations, such as TAP mode or port mirroring for traffic inspection. While it impacts performance, it is not a primary variable for firewall sizing as it is a specific use case.

This is not a key variable for sizing.

Option D: App-ID firewall throughput

App-ID throughput measures the firewall's ability to inspect traffic and apply policies based on application signatures. It directly impacts the performance of traffic inspection under real-world conditions.

This is an important sizing variable.

Option E: Telemetry enabled

While telemetry provides data for monitoring and analysis, enabling it does not significantly impact the sizing of the firewall. It is not a core variable for determining firewall performance or capacity.

This is not a key variable for sizing.
