Palo Alto Networks Systems Engineer Professional - Hardware Firewall PSE-Strata-Pro-24 Prüfungsfragen mit Lösungen (Q43-Q48):

43. Frage
Which two tools should a systems engineer use to showcase the benefit of an evaluation that a customer has just concluded?

A. Golden Images
B. Firewall Sizing Guide
C. Best Practice Assessment (BPA)
D. Security Lifecycle Review (SLR)

Antwort: C,D

Begründung:
After a customer has concluded an evaluation of Palo Alto Networks solutions, it is critical to provide a detailed analysis of the results and benefits gained during the evaluation. The following two tools are most appropriate:
* Why "Best Practice Assessment (BPA)" (Correct Answer A)?The BPA evaluates the customer's firewall configuration against Palo Alto Networks' recommended best practices. It highlights areas where the configuration could be improved to strengthen security posture. This is an excellent tool to showcase how adopting Palo Alto Networks' best practices aligns with industry standards and improves security performance.
* Why "Security Lifecycle Review (SLR)" (Correct Answer B)?The SLR provides insights into the customer's security environment based on data collected during the evaluation. It identifies vulnerabilities, risks, and malicious activities observed in the network and demonstrates how Palo Alto Networks' solutions can address these issues. SLR reports use clear visuals and metrics, making it easier to showcase the benefits of the evaluation.
* Why not "Firewall Sizing Guide" (Option C)?The Firewall Sizing Guide is a pre-sales tool used to recommend the appropriate firewall model based on the customer's network size, performance requirements, and other criteria. It is not relevant for showcasing the benefits of an evaluation.
* Why not "Golden Images" (Option D)?Golden Images refer to pre-configured templates for deploying firewalls in specific use cases. While useful for operational efficiency, they are not tools for demonstrating the outcomes or benefits of a customer evaluation.
Reference: Palo Alto Networks documentation for Best Practice Assessment (BPA) and Security Lifecycle Review (SLR) confirms their role in showcasing evaluation benefits.

44. Frage
What would make a customer choose an on-premises solution over a cloud-based SASE solution for their network?

A. High growth phase with existing and planned mergers, and with acquisitions being integrated.
B. Hybrid work and cloud adoption at various locations that have different requirements per site.
C. The need to enable business to securely expand its geographical footprint.
D. Most employees and applications in close physical proximity in a geographic region.

Antwort: D

Begründung:
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.

45. Frage
Which two files are used to deploy CN-Series firewalls in Kubernetes clusters? (Choose two.)

A. PAN-CN-MGMT-CONFIGMAP
B. PAN-CN-MGMT
C. PAN-CNI-MULTUS
D. PAN-CN-NGFW-CONFIG

Antwort: A,B

Begründung:
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.

46. Frage
A prospective customer is interested in Palo Alto Networks NGFWs and wants to evaluate the ability to segregate its internal network into unique BGP environments.
Which statement describes the ability of NGFWs to address this need?

A. It can be addressed with BGP confederations.
B. It can be addressed by creating multiple eBGP autonomous systems.
C. It cannot be addressed because BGP must be fully meshed internally to work.
D. It cannot be addressed because PAN-OS does not support it.

Antwort: A

Begründung:
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).
* "PAN-OS supports BGP for dynamic routing and network segmentation" (docs.paloaltonetworks.com/pan-os
/10-2/pan-os-networking-admin/bgp).
Step 2: Evaluate Each Option
Option A: It cannot be addressed because PAN-OS does not support it
Analysis:
PAN-OS fully supports BGP, including eBGP, iBGP, confederations, and route reflectors, configurable under
"Network > Virtual Routers > BGP."
Features like multiple virtual routers and BGP allow network segregation and routing policy control.
This statement contradicts documented capabilities.
Verification:
"Configure BGP on a virtual router for dynamic routing" (docs.paloaltonetworks.com/pan-os/10-2/pan-os- networking-admin/bgp/configure-bgp).
Conclusion: Incorrect-PAN-OS supports BGP and segregation techniques. Not Applicable.
Option B: It can be addressed by creating multiple eBGP autonomous systems Analysis:
eBGP: Used between distinct ASes, each with a unique AS number (e.g., AS 65001, AS 65002).
Within a single organization, creating multiple eBGP ASes would require:
Assigning unique AS numbers (public or private) to each internal segment.
Treating each segment as a separate AS, peering externally with other segments via eBGP.
Challenges:
Internally, this isn't practical for a single network-it's more suited to external peering (e.g., with ISPs).
Requires complex management and public/private AS number allocation, not ideal for internal segregation.
Doesn't leverage iBGP or confederations, which are designed for internal AS management.
PAN-OS supports eBGP, but this approach misaligns with the intent of internal network segregation.
Verification:
"eBGP peers connect different ASes" (docs.paloaltonetworks.com/pan-os/10-2/pan-os-networking-admin/bgp
/bgp-concepts).
Conclusion: Possible but impractical and not the intended BGP solution for internal segregation. Not Optimal

47. Frage
Which three use cases are specific to Policy Optimizer? (Choose three.)

A. Enabling migration from port-based rules to application-based rules
B. Discovering 5-tuple attributes that can be simplified to 4-tuple attributes
C. Discovering applications on the network and transitions to application-based policy over time
D. Converting broad rules based on application filters into narrow rules based on application groups
E. Automating the tagging of rules based on historical log data

Antwort: A,C,D

Begründung:
* Discovering Applications on the Network (Answer A):
* Policy Optimizeranalyzes traffic logs to identifyapplications running on the networkthat are currently being allowed by port-based or overly permissive policies.
* It providesvisibilityinto these applications, enabling administrators to transition to more secure, application-based policies over time.
* Converting Broad Rules into Narrow Rules (Answer B):
* Policy Optimizer helps refine policies byconverting broad application filters(e.g., rules that allow all web applications) intonarrower rules based on specific application groups.
* This reduces the risk of overly permissive access while maintaining granular control.
* Migrating from Port-Based Rules to Application-Based Rules (Answer C):
* One of the primary use cases for Policy Optimizer is enabling organizations tomigrate from legacy port-based rules to application-based rules, which are more secure and aligned with Zero Trust principles.
* Policy Optimizer identifies traffic patterns and automatically recommends the necessary application-based policies.
* Why Not D:
* 5-tuple attributes (source IP, destination IP, source port, destination port, protocol)are used in traditional firewalls. Simplifying these attributes to 4-tuple (e.g., removing the protocol) is not a use case for Policy Optimizer, as Palo Alto Networks NGFWs focus onapplication-based policies, not just 5-tuple matching.
* Why Not E:
* Automating tagging of rules based on historical log data is not a specific feature of Policy Optimizer. While Policy Optimizer analyzes log data to recommend policy changes, tagging is not its primary use case.

* Policy Optimizer Overview
* Transitioning to Application-Based Policies
