No active controlover routing or traffic flow is applied.

Useful for Network Auditing Before Full Deployment

Analytics mode providesvisibility into site trafficbefore committing toSD-WAN policy changes.

Helpsidentify optimization opportunitiesandtroubleshoot connectivitybefore enabling traffic steering.

(A) Access Mode– Enablesactive routing and steeringof traffic, which isnot desiredfor passive auditing.

(B) Control Mode–Actively controls traffic flowsand enforces policies, not suitable for observation-only setups.

(C) Disabled Mode– Thedevice would not functionin this mode, making it useless for traffic monitoring.

Firewall Deployment– Prisma SD-WAN ION devices must be placed in Analytics mode for initial audits.

Zero Trust Architectures– Helps assess security risks before enabling active controls.

Why Analytics Mode is the Correct Choice?Other Answer Choices AnalysisReferences and Justification:Thus,Analytics Mode (D) is the correct answer, as it allows auditing of site traffic without traffic steering.

Based on the image and default rulestack settings of theCloud NGFW for AWS, the source IP address seen in the data filtering logs will be20.10.10.15, which is the IP address of the load balancer.

Default Rulestack Behavior: By default, the rulestack settings do not inspect or preserve the original client IP (e.g., 10.1.1.2) in the "X-Forwarded-For" header. Instead, the load balancer's IP (20.10.10.15) is recorded as the source IP.

Logging Mechanism: Unless explicitly configured to parse the "X-Forwarded-For" header, the firewall's logs will reflect the IP address of the device directly sending the traffic to the NGFW (the load balancer in this case).

Data Filtering Logs and Source IP Behavior

Prisma Access, a cloud-delivered security platform by Palo Alto Networks, supports specific predefined zones to streamline policy creation and enforcement. These zones are integral to how traffic is managed and secured within the service.

Available Zones in Prisma Access:

Trust Zone:This zone encompasses all trusted and onboarded IP addresses, service connections, ormobile users within the corporate network. Traffic originating from these entities is considered trusted.

Untrust Zone:This zone includes all untrusted IP addresses, service connections, or mobile users outside the corporate network. By default, any IP address or mobile user that is not designated as trusted falls into this category.

Clientless VPN Zone:Designed to provide secure remote access to common enterprise web applications that utilize HTML, HTML5, and JavaScript technologies. This feature allows users to securely access applications from SSL-enabled web browsers without the need to install client software, which is particularly useful for enabling partner or contractor access to applications and for safely accommodating unmanaged assets, including personal devices. Notably, the Clientless VPN zone is mapped to the trust zone by default, and this setting cannot be changed.

Analysis of Options:

A. DMZ:A Demilitarized Zone (DMZ) is a physical or logical subnetwork that separates an internal local area network (LAN) from other untrusted networks, typically the internet. While traditional network architectures often employ a DMZ to add an extra layer of security, Prisma Access does not specifically define or utilize a DMZ zone within its predefined zone structure.

B. Interzone:In the context of Prisma Access, "interzone" is not a predefined zone available for user configuration. However, it's worth noting that Prisma Access logs may display a zone labeled "inter-fw," which pertains to internal communication within the Prisma Access infrastructure and is not intended for user-defined policy application.

C. Intrazone:Intrazone typically refers to traffic within the same zone. While security policies can be configured to allow or deny intrazone traffic, "Intrazone" itself is not a standalone zone available for configuration in Prisma Access.

D. Clientless VPN:As detailed above, the Clientless VPN is a predefined zone in Prisma Access, designed to facilitate secure, clientless access to web applications.

Conclusion:

Among the options provided,D. Clientless VPNis the correct answer, as it is an available predefined zone in Prisma Access.

Migrating a perpetual VM-Series firewall license to a flexible VM-Series license involves specific configurations to ensure a seamless transition. The process requires careful planning and execution to align with Palo Alto Networks' licensing models and deployment strategies.

A. Choose "Fixed vCPU Models" for configuration type.When creating a deployment profile for the migration, selecting the appropriate configuration type is crucial. Palo Alto Networks offers two configuration types: Fixed vCPU Models and Flexible vCPU Models.

Fixed vCPU Models:

This configuration aligns with traditional VM-Series models (e.g., VM-300, VM-500) and is suitable for environments where the firewall's resource allocation remains consistent.

Choosing this option ensures that the migrated firewall retains a familiar resource profile, simplifying the transition from a perpetual license.

Flexible vCPU Models:

This configuration allows for dynamic allocation of vCPUs, providing scalability based on varying workload demands.

While offering flexibility, it requires careful planning to match resource allocation with licensing entitlements.

For a straightforward migration that maintains existing resource allocations, selecting "Fixed vCPU Models" is recommended. This choice ensures compatibility with the perpetual VM's configuration and simplifies the licensing transition.

C. Deploy virtual Panorama for management.Effective management of VM-Series firewalls, especially during a migration, necessitates acentralized management platform. Panorama, Palo Alto Networks' centralized management solution, provides comprehensive tools for configuration, monitoring, and licensing management.

Centralized Management:

Panorama offers a single interface to manage multiple firewalls, streamlining policy updates and configuration changes.

Licensing Management:

During the migration to a flexible VM-Series license, Panorama facilitates the application of new licenses and ensures compliance across all managed devices.

Visibility and Reporting:

With Panorama, administrators gain enhanced visibility into traffic patterns and security events, which is crucial during transitional periods.

Deploying a virtual Panorama instance ensures that the migration process is managed efficiently, reducing the risk of configuration errors and ensuring that all firewalls operate under the correct licensing model.

Incorrect Options:

B. Allocate the same number of vCPUs as the perpetual VM.

While maintaining the same number of vCPUs might seem logical, the flexible licensing model allows for dynamic allocation based on current needs. Strictly matching the perpetual VM's vCPU count may not leverage the benefits of the flexible model.

D. Allow only the same security services as the perpetual VM.

The flexible licensing model provides an opportunity to reassess and potentially enhance the security services in use. Restricting to the same services may limit the advantages offered by the new licensing structure.

By selecting the appropriate configuration type and utilizing Panorama for centralized management, organizations can ensure a smooth and efficient migration from a perpetual VM-Series firewall license to a flexible VM-Series license.

When configuringHigh Availability (HA)settings inPanorama, administrators need to ensure that each firewall in the HA pair has a uniquePeer HA1 IP addresswhile using ashared template stack. This is achieved usingTemplate Variables, which allow dynamic configurations per firewall.

Ensures Unique HA1 IP Addresses

HA pairs requiretwo separate HA1 IP addresses(one per firewall).

Usingtemplate variables, the administrator can assign different values to each firewallwithout creating separate templates.

Template Variables Provide Flexibility

Instead ofhardcodingHA1 IP addresses in the template, variables allow different firewalls todynamically inherit unique values.

Thisavoids duplicationand ensures configurationscalabilitywhen managing multiple firewalls.

(A) Template Stack– Defines the overall configuration hierarchy but doesnot provide dynamic IP assignment.

(C) Address Object– Used forsecurity policies and NAT rules, not for HA configurations.

(D) Dynamic Address Group– Primarily used forautomated security policies, not HA settings.

Firewall Deployment– HA configurations require unique peer IPs, and template variables provide dynamic assignment.

Panorama– Template variables enhance scalability and simplify HA configurations across multiple devices.

Why Template Variable is the Correct Answer?Other Answer Choices AnalysisReferences and Justification:Thus,Template Variable (B) is the correct answer, as it allows dynamic peer HA1 IP assignment while using a shared template stack in Panorama.

When a user authenticates and connects to aGlobalProtect gateway, the firewall can collect and evaluate device information usingHost Information Profile (HIP). This feature helps enforce security policies based on the device’s posture before granting or restricting network access.

What is HIP?

Host Information Profile (HIP)is a feature in GlobalProtect that gathers security-related information from the endpoint device, such as:

OS version

Patch level

Antivirus status

Disk encryption status

Host-based firewall status

Running applications

How Does HIP Work?

When a user connects to aGlobalProtect gateway, their device submits itsHIP reportto the firewall.

The firewallevaluatesthis information againstconfigured security policies.

If the devicemeets security compliance, access is granted; otherwise,remediation actions(e.g., blocking access) can be applied.

(A) RADIUS Authentication– While RADIUS is used for user authentication, it doesnot collect device security posture.

(B) IP Address– The user's IP address is tracked but does not providedevice security information.

(D) Session ID– A session ID identifies the user session but does not collect host-based security details.

Firewall Deployment– HIP profiles help enforce security policies based on device posture.

Security Policies– Administrators use HIP checks to restrict non-compliant devices.

Threat Prevention & WildFire– HIP ensures that endpoints are properly patched and protected.

Panorama– HIP reports can be monitored centrally via Panorama.

Zero Trust Architectures– HIP enforcesdevice trustin Zero Trust models.

Why is HIP the Correct Answer?Other Answer Choices AnalysisReferences and Justification:Thus,Host Information Profile (HIP) is the correct answer, as it collects device security information when a user connects to a GlobalProtect gateway.

In Palo Alto Networks Next-Generation Firewall (NGFW), packet processing is categorized into thefast path(also known as theaccelerated path) and theslow path(also known asdeep inspection processing). Theslow pathis responsible for handling operations that require deep content inspection and policy enforcement beyond standard Layer 2-4 packet forwarding.

Slow Path Processing and SSL/TLS DecryptionSSL/TLS decryption is performedonly during the slow pathbecause it involves computationally intensive tasks such as:

Intercepting encrypted trafficand performing man-in-the-middle (MITM) decryption.

Extracting the SSL handshakeand certificate details for security inspection.

Inspecting decrypted payloadsfor threats, malicious content, and compliance with security policies.

Re-encrypting the trafficbefore forwarding it to the intended destination.

This process is critical in environments whereencrypted threatscan bypass traditional security inspection mechanisms. However, it significantly impacts firewall performance, making it a slow path action.

(A) Session Lookup– This occurs in thefast pathas part of session establishment before any deeper inspection. It checks whether an incoming packet belongs to an existing session.

(C) Layer 2–Layer 4 Firewall Processing– These arestateless or stateful filtering actions(e.g., access control, NAT, and basic connection tracking), handled in the fast path.

(D) Security Policy Lookup– This is also in thefast path, where the firewall determines whether to allow, deny, or perform further inspection based on the defined security policy rules.

Firewall Deployment– SSL/TLS decryption is part of the firewall’s deep packet inspection and Zero Trust enforcement strategies.

Security Policies– NGFWs use SSL decryption to enforce security policies, ensuring compliance and blocking encrypted threats.

VPN Configurations– SSL VPNs and IPsec VPNs also undergo decryption processing in specific security enforcement zones.

Threat Prevention– Palo Alto’s Threat Prevention engine analyzes decrypted traffic for malware, C2 (Command-and-Control) connections, and exploit attempts.

WildFire– Inspects decrypted traffic for zero-day malware and sandboxing analysis.

Panorama– Provides centralized logging and policy enforcement for SSL decryption events.

Zero Trust Architectures– Decryption is a crucial Zero Trust principle, ensuring encrypted traffic is not blindly trusted.

Other Answer Choices AnalysisReferences and Justification:Thus,SSL/TLS decryption is the correct answeras it is performed exclusively in the slow path of Palo Alto Networks NGFWs.

To generate authorization codes for Software Next-Generation Firewalls (NGFWs), it is necessary to create a deployment profile within the Palo Alto Networks Customer Support Portal (CSP). This process involves defining the specifics of your deployment, such as the desired firewall model, associated subscriptions, and other relevant configurations.

Once the deployment profile is established, the CSP generates an authorization code corresponding to the specified configuration. This code is then used during the firewall's activation process to license the software and enable the associated subscriptions.

It's important to note that authorization codes are not typically obtained directly from public cloud marketplaces or through Enterprise Support Agreement (ESA) codes. Additionally, while registering the device with the cloud service provider is a necessary step, it does not, by itself, generate the required authorization codes.

Theinline cloud analysis featurein theAdvanced Threat Preventionsubscription enablesreal-time threat detection using machine learning (ML) and deep-learning models. However, for it to be effective, the firewall mustdecrypt encrypted trafficto analyze potential threats hidden withinTLS/SSL connections.

Threat actors often hide malware and exploits in encrypted traffic.

Without SSL decryption, inline cloud analysis cannot inspect encrypted threats.

Decryption allows full visibility into traffic for inline deep-learning threat detection.

A. Configure Advanced Threat Prevention profiles with default settings and only focus on high-risk traffic to avoid affecting network performance.❌

Incorrect, becausedefault settings may not enable inline cloud analysis, and focusingonly on high-risk traffic reduces security effectiveness.

C. Update or create a new anti-spyware security profile and enable the appropriate local deep-learning models.❌

Incorrect, becauseAnti-Spyware profiles detect command-and-control (C2) traffic, butinline cloud analysis requires inspecting full packet content, which requires SSL decryption.

D. Disable anti-spyware to avoid performance impacts and rely solely on external threat intelligence.❌

Incorrect, becausedisabling anti-spyware would leave the network vulnerable. Inline cloud analysis worksin conjunction with threat intelligence and local prevention capabilities.

When log forwarding from aPalo Alto Networks NGFWto theStrata Logging Service (formerly Cortex Data Lake)becomes disconnected, the primary aspect to review isdevice certificates. This is because the firewall usescertificatesfor mutual authentication with the logging service. If these certificates are missing, expired, or invalid, the firewall will fail to establish a secure connection, preventing log forwarding.

Authentication Requirement– The NGFW uses a Palo Alto Networks-issued device certificate for authentication before it can send logs to the Strata Logging Service.

Expiration Issues– If the certificate has expired, the NGFW will be unable to authenticate, causing a disconnection.

Misconfiguration or Revocation– If the certificate is not properly installed, revoked, or incorrectly assigned, the logging service will reject log forwarding attempts.

Cloud Trust Relationship– The firewall relies on secure cloud-based authentication, where certificates validate the NGFW’s identity before log ingestion.

Check Certificate Status

Navigate toDevice > Certificatesin the NGFW web interface.

Verify the presence of a validPalo Alto Networks device certificate.

Look for expiration dates and renew if necessary.

Reinstall Certificates

If the certificate is missing or invalid, reinstall it by retrieving the correct device certificate from thePalo Alto Networks Customer Support Portal (CSP).

Ensure Correct Certificate Chain

Verify that the correct root CA certificate is installed and trusted by the firewall.

Confirm Connectivity to Strata Logging Service

Ensure that outbound connections to the logging service are not blocked due to misconfigured security policies, firewalls, or proxies.

(B) Decryption Profile– SSL/TLS decryption settings affect traffic inspection but have no impact on log forwarding.

(C) Auth Codes– Authentication codes are used during theinitial device registrationwith Strata Logging Service but do not impact ongoing log forwarding.

(D) Software Warranty– The firewall’swarrantydoes not influence log forwarding; however, anactive support licenseis required for continuous access to Strata Logging Service.

Firewall Deployment– Certificates are fundamental to secure NGFW cloud communication.

Security Policies– Proper authentication ensures logs are securely transmitted.

Threat Prevention & WildFire– Logging failures could impact threat visibility and WildFire analysis.

Panorama– Uses the same authentication mechanisms for centralized logging.

Zero Trust Architectures– Requires strict identity verification, including valid certificates.

Key Reasons Why Device Certificates Are CriticalHow to Verify and Fix Certificate IssuesOther Answer Choices AnalysisReferences and Justification:Thus,Device Certificates (A)is the correct answer, as log forwarding depends on a valid, authenticated certificate to establish connectivity with Strata Logging Service.
