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.

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.

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?

LDAP Query (Answer B):

Palo Alto Networks NGFWs can queryLDAP directories(such as Active Directory) to validate whether submitted credentials match the corporate directory.

Domain Credential Filter (Answer C):

TheDomain Credential Filterfeature ensures that submitted credentials are checked against valid corporate credentials, preventing credential misuse.

Why Not A:

Group mappingis used to identify user groups for policy enforcement but does not validate submitted credentials.

Why Not D:

WMI client probingis used for user identification but is not a method for validating submitted credentials.

Firewall Sizing Tool (Answer B):

Thefirewall sizing toolis the most accurate way to determine the suitable firewall model based on specific customer requirements, such as throughput, connections per second, and enabled features like App-ID and Threat Prevention.

By inputting traffic patterns, feature requirements, and performance needs, the sizing tool provides tailored recommendations.

Why Not A:

While uploading traffic logs to the calculator tool may help analyze traffic trends, it is not the primary method for determining firewall sizing.

Why Not C or D:

Theproduct configurator toolandproduct selector toolare not designed for detailed performance analysis based on real-world requirements like connections per second or enabled features.

Create a New Threat Profile (Answer B):

Performance tuning inIntrusion Prevention System (IPS)involves ensuring that only the most relevant and necessary signatures are enabled for the specific environment.

Palo Alto Networks allows you to createcustom threat profilesto selectively enable signatures that match the threats most likely to affect the environment. This reduces unnecessary resource usage and ensures optimal performance.

By tailoring the signature set, organizations can focus on real threats without impacting overall throughput and latency.

Why Not A:

Leaving all signatures turned on is not a best practice because it may consume excessive resources, increasing processing time and degrading firewall performance, especially in high-throughput environments.

Why Not C:

While working with TAC for debugging may help identify specific performance bottlenecks, it is not a recommended approach for routine performance tuning. Instead, proactive configuration changes, such as creating tailored threat profiles, should be made.

Why Not D:

Disabling irrelevant threat signatures can improve performance, but this task is effectively accomplished bycreating a new threat profile. Manually disabling signatures one by one is not scalable or efficient.

SASE (Secure Access Service Edge) is a cloud-based solution that combines networking and security capabilities to address modern enterprise needs. However, there are scenarios where an on-premises solution is more appropriate.

A. High growth phase with existing and planned mergers, and with acquisitions being integrated.

This scenario typically favors a SASE solution since it provides flexible, scalable, and centralized security that is ideal for integrating newly acquired businesses.

B. Most employees and applications in close physical proximity in a geographic region.

This scenario supports the choice of an on-premises solution. When employees and applications are concentrated in a single geographic region, traditional on-premises firewalls and centralized security appliances provide cost-effective and efficient protection without the need for distributed, cloud-based infrastructure.

C. Hybrid work and cloud adoption at various locations that have different requirements per site.

This scenario aligns with a SASE solution. Hybrid work and varying site requirements are better addressed by SASE’s ability to provide consistent security policies regardless of location.

D. The need to enable business to securely expand its geographical footprint.

Expanding into new geographic areas benefits from the scalability and flexibility of a SASE solution, which can deliver consistent security globally without requiring physical appliances at each location.

Key Takeaways:

On-premises solutions are ideal for geographically concentrated networks with minimal cloud adoption.

SASE is better suited for hybrid work, cloud adoption, and distributed networks.

On-Premises vs. SASE Deployment Guide

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.
