Palo Alto Networks Systems Engineer Professional - Hardware Firewall Sample Questions (Q26-Q31):NEW QUESTION # 26
While responding to a customer RFP, a systems engineer (SE) is presented the question, "How do PANW firewalls enable the mapping of transactions as part of Zero Trust principles?" Which two narratives can the SE use to respond to the question? (Choose two.)
  • A. Describe how Palo Alto Networks NGFW Security policies are built by using users, applications, and data objects.
  • B. Emphasize Zero Trust as an ideology, and that the customer decides how to align to Zero Trust principles.
  • C. Explain how the NGFW can be placed in the network so it has visibility into every traffic flow.
  • D. Reinforce the importance of decryption and security protections to verify traffic that is not malicious.
Answer: A,D
Explanation:
The question asks how Palo Alto Networks (PANW) Strata Hardware Firewalls enable the mapping of transactions as part of Zero Trust principles, requiring a systems engineer (SE) to provide two narratives for a customer RFP response. Zero Trust is a security model that assumes no trust by default, requiring continuous verification of all transactions, users, and devices-inside and outside the network. The Palo Alto Networks Next-Generation Firewall (NGFW), part of the Strata portfolio, supports this through its advanced visibility, decryption, and policy enforcement capabilities. Below is a detailed explanation of why options B and D are the correct narratives, verified against official Palo Alto Networks documentation.
Step 1: Understanding Zero Trust and Transaction Mapping in PAN-OS
Zero Trust principles, as defined by frameworks like NIST SP 800-207, emphasize identifying and verifying every transaction (e.g., network flows, application requests) based on context such as user identity, application, and data. For Palo Alto Networks NGFWs, "mapping of transactions" refers to the ability to identify, classify, and control network traffic with granular detail, enabling verification and enforcement aligned with Zero Trust.
The PAN-OS operating system achieves this through:
* App-ID: Identifies applications regardless of port or protocol.
* User-ID: Maps IP addresses to user identities.
* Content-ID: Inspects and protects content, including decryption for visibility.
* Security Policies: Enforces rules based on these mappings.
Reference: Palo Alto Networks Zero Trust Architecture Guide
"Zero Trust requires visibility into all traffic, verification of trust, and enforcement of least privilege policies- capabilities delivered by PAN-OS through App-ID, User-ID, and Content-ID." Step 2: Evaluating the Narratives Let's analyze each option to determine which two best explain how PANW firewalls enable transaction mapping for Zero Trust:
Option A: Emphasize Zero Trust as an ideology, and that the customer decides how to align to Zero Trust principles.
Analysis: While Zero Trust is indeed a guiding philosophy, this narrative is vague and does not directly address how the firewall enables transaction mapping. It shifts responsibility to the customer without highlighting specific PAN-OS capabilities, making it less relevant to the question.
Conclusion: Not a suitable answer.
Reference: Palo Alto Networks Zero Trust Overview - "Zero Trust is a strategy, but Palo Alto Networks provides the tools to implement it." Option B: Reinforce the importance of decryption and security protections to verify traffic that is not malicious.
Analysis: Decryption is a cornerstone of Zero Trust because encrypted traffic (e.g., TLS/SSL) can hide malicious activity. PAN-OS NGFWs use SSL Forward Proxy and SSL Inbound Inspection to decrypt traffic, allowing full visibility into transactions. Once decrypted, App-ID and Content-ID classify the traffic and apply security protections (e.g., threat prevention, URL filtering) to verify it aligns with policy and is not malicious. This directly enables transaction mapping by ensuring all flows are identified and verified.
Step-by-Step Explanation:
Enable decryption under Policies > Decryption to inspect encrypted traffic.
App-ID identifies the application (e.g., HTTPS-based apps).
Content-ID scans for threats, ensuring the transaction is safe.
Logs (e.g., Traffic, Threat) map the transaction details (source, destination, app, user).
Conclusion: Correct answer-directly ties to transaction mapping via visibility and verification.
Reference: PAN-OS Administrator's Guide (11.1) - Decryption Overview
"Decryption enables visibility into encrypted traffic, a requirement for Zero Trust, allowing the firewall to apply security policies and log transaction details." Option C: Explain how the NGFW can be placed in the network so it has visibility into every traffic flow.
Analysis: Network placement (e.g., inline deployment) is important for visibility, but it's a deployment strategy, not a capability of the firewall itself. While visibility is a prerequisite for Zero Trust, this narrative does not explain how the firewall maps transactions (e.g., via App-ID or User-ID). It's too indirect to fully address the question.
Conclusion: Not the strongest answer.
Reference: PAN-OS Deployment Guide - "Inline placement ensures visibility, but mapping requires App-ID and User-ID." Option D: Describe how Palo Alto Networks NGFW Security policies are built by using users, applications, and data objects.
Analysis: This narrative highlights the core PAN-OS features-User-ID, App-ID, and Content-ID-that enable transaction mapping. Security policies in PAN-OS are defined using:
Users: Mapped via User-ID from directory services (e.g., AD).
Applications: Identified by App-ID, even within encrypted flows.
Data Objects: Controlled via Content-ID (e.g., file types, sensitive data).These policies log and enforce transactions, providing the granular context required for Zero Trust (e.g., "Allow user Alice to access Salesforce, but block file uploads").
Step-by-Step Explanation:
Configure User-ID (Device > User Identification) to map IPs to users.
Use App-ID in policies (Policies > Security) to identify apps.
Define data objects (e.g., Objects > Custom Objects > Data Patterns) for content control.
Logs (e.g., Monitor > Logs > Traffic) record transaction mappings.
Conclusion: Correct answer-directly explains transaction mapping via policy enforcement.
Reference: PAN-OS Administrator's Guide (11.1) - Security Policy
"Security policies leverage User-ID, App-ID, and Content-ID to map and control transactions, aligning with Zero Trust least privilege." Step 3: Why B and D Are the Best Choices B: Focuses on decryption and verification, ensuring all transactions (even encrypted ones) are mapped and validated, a critical Zero Trust requirement.
D: Highlights the policy framework that maps transactions to users, apps, and data, enabling granular control and logging-core to Zero Trust enforcement.Together, they cover visibility (B) and enforcement (D), fully addressing how PANW firewalls implement transaction mapping for Zero Trust.
Step 4: Sample RFP Response Narratives
B Narrative: "alo Alto Networks NGFWs enable Zero Trust by decrypting traffic to provide full visibility into transactions. Using SSL decryption and integrated security protections like threat prevention, the firewall verifies that traffic is not malicious, mapping every flow to ensure compliance with Zero Trust principles." D Narrative: "Our NGFWs map transactions through security policies built on users, applications, and data objects. By leveraging User-ID, App-ID, and Content-ID, the firewall identifies who is accessing what application and what data is involved, enforcing least privilege and logging every transaction for Zero Trust alignment." Conclusion The two narratives that best explain how PANW Strata Hardware Firewalls enable transaction mapping for Zero Trust are B and D. These are grounded in PAN-OS capabilities-decryption for visibility and policy- based mapping-verified by Palo Alto Networks documentation up to March 08, 2025, including PAN-OS
11.1 and the Zero Trust Architecture Guide.

NEW QUESTION # 27
Which three known variables can assist with sizing an NGFW appliance? (Choose three.)
  • A. Telemetry enabled
  • B. Packet replication
  • C. Connections per second
  • D. Max sessions
  • E. App-ID firewall throughput
Answer: C,D,E
Explanation:
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.

* Palo Alto Networks documentation on Firewall Sizing Guidelines
* Knowledge Base article on Performance and Capacity Sizing

NEW QUESTION # 28
Which two statements correctly describe best practices for sizing a firewall deployment with decryption enabled? (Choose two.)
  • A. Rivest-Shamir-Adleman (RSA) certificate authentication method (not the RSA key exchange algorithm) consumes more resources than Elliptic Curve Digital Signature Algorithm (ECDSA), but ECDSA is more secure.
  • B. SSL decryption traffic amounts vary from network to network.
  • C. Perfect Forward Secrecy (PFS) ephemeral key exchange algorithms such as Diffie-Hellman Ephemeral (DHE) and Elliptic-Curve Diffie-Hellman Exchange (ECDHE) consume more processing resources than Rivest-Shamir-Adleman (RSA) algorithms.
  • D. Large average transaction sizes consume more processing power to decrypt.
Answer: B,C
Explanation:
When planning a firewall deployment with SSL/TLS decryption enabled, it is crucial to consider the additional processing overhead introduced by decrypting and inspecting encrypted traffic. Here are the details for each statement:
* Why "SSL decryption traffic amounts vary from network to network" (Correct Answer A)?SSL decryption traffic varies depending on the organization's specific network environment, user behavior, and applications. For example, networks with heavy web traffic, cloud applications, or encrypted VoIP traffic will have more SSL/TLS decryption processing requirements. This variability means each deployment must be properly assessed and sized accordingly.
* Why "erfect Forward Secrecy (PFS) ephemeral key exchange algorithms such as Diffie-Hellman Ephemeral (DHE) and Elliptic-Curve Diffie-Hellman Exchange (ECDHE) consume more processing resources than Rivest-Shamir-Adleman (RSA) algorithms" (Correct Answer C)?PFS algorithms like DHE and ECDHE generate unique session keys for each connection, ensuring better security but requiring significantly more processing power compared to RSA key exchange. When decryption is enabled, firewalls must handle these computationally expensive operations for every encrypted session, impacting performance and sizing requirements.
* Why not "Large average transaction sizes consume more processing power to decrypt" (Option B)?While large transaction sizes can consume additional resources, SSL/TLS decryption is more dependent on the number of sessions and the complexity of the encryption algorithms used, rather than the size of the transactions. Hence, this is not a primary best practice consideration.
* Why not "Rivest-Shamir-Adleman (RSA) certificate authentication method consumes more resources than Elliptic Curve Digital Signature Algorithm (ECDSA), but ECDSA is more secure" (Option D)?This statement discusses certificate authentication methods, not SSL/TLS decryption performance. While ECDSA is more efficient and secure than RSA, it is not directlyrelevant to sizing considerations for firewall deployments with decryption enabled.

NEW QUESTION # 29
According to a customer's CIO, who is upgrading PAN-OS versions, "Finding issues and then engaging with your support people requires expertise that our operations team can better utilize elsewhere on more valuable tasks for the business." The upgrade project was initiated in a rush because the company did not have the appropriate tools to indicate that their current NGFWs were reaching capacity.
Which two actions by the Palo Alto Networks team offer a long-term solution for the customer? (Choose two.)
  • A. Propose AIOps Premium within Strata Cloud Manager (SCM) to address the company's issues from within the existing technology.
  • B. Inform the CIO that the new enhanced security features they will gain from the PAN-OS upgrades will fix any future problems with upgrading and capacity.
  • C. Recommend that the operations team use the free machine learning-powered AIOps for NGFW tool.
  • D. Suggest the inclusion of training into the proposal so that the operations team is informed and confident in working on their firewalls.
Answer: A,D
Explanation:
The customer's CIO highlights two key pain points: (1) the operations team lacks expertise to efficiently manage PAN-OS upgrades and support interactions, diverting focus from valuable tasks, and (2) the company lacked tools to monitor NGFW capacity, leading to a rushed upgrade. The goal is to recommend long-term solutions leveraging Palo Alto Networks' offerings for Strata Hardware Firewalls. Options B and D-training and AIOps Premium within Strata Cloud Manager (SCM)- address these issues by enhancing team capability and providing proactive management tools. Below is a detailed explanation, verified against official documentation.
Step 1: Analyzing the Customer's Challenges
* Expertise Gap: The CIO notes that identifying issues and engaging support requires expertise the operations team doesn't fully have or can't prioritize. Upgrading PAN-OS on Strata NGFWs involves tasks like version compatibility checks, pre-upgrade validation, and troubleshooting, which demand familiarity with PAN-OS tools and processes.
* Capacity Visibility: The rushed upgrade stemmed from not knowing the NGFWs were nearing capacity (e.g., CPU, memory, session limits), indicating a lack of monitoring or predictive analytics.
Long-term solutions must address both operational efficiency and proactive capacity management, aligning with Palo Alto Networks' ecosystem for Strata firewalls.
Reference: PAN-OS Administrator's Guide (11.1) - Upgrade Overview
"Successful upgrades require planning, validation, and monitoring to avoid disruptions and ensure capacity is sufficient." Step 2: Evaluating the Recommended Actions Option A: Recommend that the operations team use the free machine learning-powered AIOps for NGFW tool.
Analysis: AIOps for NGFW (free version) is a cloud-based tool that uses machine learning to monitor firewall health, detect anomalies, and provide upgrade recommendations. It offers basic telemetry (e.g., CPU usage, session counts) and alerts, which could have flagged capacity issues earlier. However, it lacks advanced features like automated remediation, detailed capacity planning, or integration with Strata Cloud Manager, limiting its long-term impact. Additionally, it doesn't address the expertise gap, as the team still needs knowledge to interpret and act on insights.
Conclusion: Helpful but not a comprehensive long-term solution.
Reference: AIOps for NGFW Documentation
"The free version provides basic health monitoring and ML-driven insights but lacks premium features for proactive management." Option B: Suggest the inclusion of training into the proposal so that the operations team is informed and confident in working on their firewalls.
Analysis: Palo Alto Networks offers training through the Palo Alto Networks Authorized Training Partners and Cybersecurity Academy, covering PAN-OS administration, upgrades, and troubleshooting. For Strata NGFWs, courses like "Firewall Essentials: Configuration and Management (EDU-210)" teach upgrade best practices, capacity monitoring (e.g., via Device > High Availability > Resources), and support engagement.
How It Solves the Issue:
Reduces reliance on external expertise by upskilling the team.
Enables efficient upgrade planning (e.g., using Best Practice Assessment (BPA) tool).
Frees the team for higher-value tasks by minimizing support escalations.
Long-Term Benefit: A trained team can proactively manage upgrades and capacity, addressing the CIO's concern about expertise allocation.
Conclusion: A strong long-term solution.
Reference: Palo Alto Networks Training Catalog
"Training empowers operations teams to confidently manage NGFWs, including upgrades and capacity planning." Option C: Inform the CIO that the new enhanced security features they will gain from the PAN-OS upgrades will fix any future problems with upgrading and capacity.
Analysis: New PAN-OS versions (e.g., 11.1) bring features like enhanced App-ID, decryption, or ML- based threat detection, improving security. However, these don't inherently solve upgrade complexity or capacity visibility. Capacity issues depend on hardware limits (e.g., PA-5200 Series max sessions), not software features, and upgrades still require expertise. This response oversells benefits without addressing root causes.
Conclusion: Not a valid long-term solution.
Reference: PAN-OS 11.1 Release Notes
"New features enhance security but do not automate upgrade processes or capacity monitoring." Option D: Propose AIOps Premium within Strata Cloud Manager (SCM) to address the company's issues from within the existing technology.
Analysis: AIOps Premium, integrated with Strata Cloud Manager (SCM), is a subscription-based service for managing Strata NGFWs. It provides:
Predictive Analytics: Forecasts capacity needs (e.g., CPU, memory, sessions) using ML.
Upgrade Planning: Recommends optimal upgrade paths and validates configurations.
Proactive Alerts: Identifies issues before they escalate, reducing support calls.
Centralized Management: Monitors all firewalls from SCM, integrating with existing PAN-OS deployments.
How It Solves the Issue:
Prevents rushed upgrades by predicting capacity limits (e.g., via Capacity Saturation Reports).
Simplifies upgrade preparation with automated insights, reducing expertise demands.
Aligns with existing Strata technology, enhancing ROI.
Long-Term Benefit: Offers a scalable, proactive toolset to manage NGFWs, addressing both capacity and operational efficiency.
Conclusion: A robust long-term solution.
Reference: Strata Cloud Manager AIOps Premium Documentation
"AIOps Premium provides advanced capacity planning and upgrade readiness, minimizing operational burden." Step 3: Why B and D Are the Best Choices B (Training): Directly tackles the expertise gap, empowering the team to handle upgrades and capacity monitoring independently. It's a foundational fix, ensuring long-term self-sufficiency.
D (AIOps Premium in SCM): Provides a technological solution to preempt capacity issues and streamline upgrades, reducing the need for deep expertise and support escalations. It complements training by automating complex tasks.
Synergy: Together, they address both human (expertise) and systemic (tools) challenges, aligning with the CIO's goals of operational efficiency and business value.
Step 4: How These Actions Integrate with Strata NGFWs
Training: Teaches use of PAN-OS tools like System Resources (CLI: show system resources) and Dynamic Updates for capacity and upgrade prep.
AIOps Premium: Enhances Strata NGFW management via SCM, pulling telemetry (e.g., from Device > Setup > Telemetry) to predict and resolve issues.
Reference: PAN-OS Administrator's Guide (11.1) - Monitoring
"Combine training and tools like AIOps to optimize NGFW performance and upgrades."

NEW QUESTION # 30
Device-ID can be used in which three policies? (Choose three.)
  • A. Quality of Service (QoS)
  • B. SD-WAN
  • C. Policy-based forwarding (PBF)
  • D. Security
  • E. Decryption
Answer: A,D,E
Explanation:
The question asks about the policies where Device-ID, a feature of Palo Alto Networks NGFWs, can be applied. Device-ID enables the firewall to identify and classify devices (e.g., IoT, endpoints) based on attributes like device type, OS, or behavior, enhancing policy enforcement. Let's evaluate its use across the specified policy types.
Step 1: Understand Device-ID
Device-ID leverages the IoT Security subscription and integrates with the Strata Firewall to provide device visibility and control. It uses data from sources like DHCP, HTTP headers, and machinelearning to identify devices and allows policies to reference device objects (e.g., "IP Camera," "Medical Device"). This feature is available on PA-Series firewalls running PAN-OS 10.0 or later with the appropriate license.
