Paloalto Networks PSE-Strata-Pro-24 Dumps

Understanding the Problem:

The issue is thatAdvanced Threat Prevention (ATP) logsare visible on the firewall but are not being ingested into the company’s SIEM.

This implies that the ATP subscription is working and generating logs on the firewall but the logs are not being forwarded properly to the SIEM.

Action to Resolve:

Log Forwarding Configuration:

Verify that the Security policy rules configured to inspect traffic using Advanced Threat Prevention are set toforward logsto the SIEM instance.

This is a common oversight. Even if the logs are generated locally, they will not be forwarded unless explicitly configured.

Configuration steps to verify in the Palo Alto Networks firewall:

Go toPolicies > Security Policiesand check the "Log Forwarding" profile applied.

Ensure the "Log Forwarding" profile includes the correct settings to forwardThreat Logsto the SIEM.

Go toDevice > Log Settingsand ensure the firewall is set to forward Threat logs to the desired Syslog or SIEM destination.

Why Not the Other Options?

A (Enable the Threat Prevention license):

The problem does not relate to the license; the administrator already confirmed the license is active.

B (Check with the SIEM vendor):

While verifying SIEM functionality is important, the first step is to ensure the logs are being forwarded correctly from the firewall to the SIEM. This is under the systems administrator’s control.

C (Have the SIEM vendor troubleshoot):

This step should only be takenafterconfirming the logs are forwarded properly from the firewall.

Strata Cloud Manager (SCM) is Palo Alto Networks’ centralized cloud-based management platform for managing network security solutions, including Prisma Access and Prisma SD-WAN. SCM can also integrate with VM-Series firewalls for managing virtualized NGFW deployments.

Why A (Prisma SD-WAN) Is Correct

SCM is the management interface for Prisma SD-WAN, enabling centralized orchestration, monitoring, and configuration of SD-WAN deployments.

Why D (VM-Series NGFW) Is Correct

SCM supports managing VM-Series NGFWs, providing centralized visibility and control for virtualized firewall deployments in cloud or on-premises environments.

Why Other Options Are Incorrect

B (Prisma Cloud):Prisma Cloud is a separate product for securing workloads in public cloud environments. It is not managed via SCM.

C (Cortex XDR):Cortex XDR is a platform for endpoint detection and response (EDR). It is managed through its own console, not SCM.

Palo Alto Networks Strata Cloud Manager Overview

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).

References: "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.

Option C: It can be addressed with BGP confederations

Description: BGP confederations divide a single AS into sub-ASes (each with a private Confederation Member AS number), reducing the iBGP full-mesh requirement while maintaining a unified external AS.

Analysis:

How It Works:

Single AS (e.g., AS 65000) is split into sub-ASes (e.g., 65001, 65002).

Within each sub-AS, iBGP full mesh or route reflectors are used.

Between sub-ASes, eBGP-like peering (confederation EBGP) connects them, but externally, it appears as one AS.

Segregation:

Each sub-AS can represent a unique BGP environment (e.g., department, site) with its own routing policies.

Firewalls within a sub-AS peer via iBGP; across sub-ASes, they use confederation EBGP.

PAN-OS Support:

Configurable under "Network > Virtual Routers > BGP > Confederation" with a Confederation Member AS number.

Ideal for large internal networks needing segmentation without multiple public AS numbers.

Benefits:

Simplifies internal BGP management.

Aligns with the customer’s need for unique internal BGP environments.

Verification:

"BGP confederations reduce full-mesh burden by dividing an AS into sub-ASes" (docs.paloaltonetworks.com/pan-os/10-2/pan-os-networking-admin/bgp/bgp-confederations).

"Supports unique internal routing domains" (knowledgebase.paloaltonetworks.com).

Conclusion: Directly addresses the requirement with a supported, practical solution.Applicable.

Option D: It cannot be addressed because BGP must be fully meshed internally to work

Analysis:

iBGP Full Mesh: Traditional iBGP requires all routers in an AS to peer with each other, scaling poorly (n(n-1)/2 connections).

Mitigation: PAN-OS supports alternatives:

Route Reflectors: Centralize iBGP peering.

Confederations: Divide the AS into sub-ASes (see Option C).

This statement ignores these features, falsely claiming BGP’s limitation prevents segregation.

Verification:

"Confederations and route reflectors eliminate full-mesh needs" (docs.paloaltonetworks.com/pan-os/10-2/pan-os-networking-admin/bgp/bgp-confederations).

Conclusion: Incorrect—PAN-OS overcomes full-mesh constraints.Not Applicable.

Step 3: Recommendation Justification

Why Option C?

Alignment: Confederations allow the internal network to be segregated into unique BGP environments (sub-ASes) while maintaining a single external AS, perfectly matching the customer’s need.

Scalability: Reduces iBGP full-mesh complexity, ideal for large or segmented internal networks.

PAN-OS Support: Explicitly implemented in BGP configuration, validated by documentation.

Why Not Others?

A: False—PAN-OS supports BGP and segregation.

B: eBGP is for external ASes, not internal segregation; less practical thanconfederations.

D: Misrepresents BGP capabilities; full mesh isn’t required with confederations or route reflectors.
