Palo Alto Networks PSE-HARDWARE-FIREWAL Online Questions & Answers

• Question 11:

  What is the minimum configuration to stop a Cobalt Strike Malleable C2 attack inline and in real time?

  A. Next-Generation CASB on PAN-OS 10.1
  B. Advanced Threat Prevention and PAN-OS 10.2
  C. Threat Prevention and Advanced WildFire with PAN-OS 10.0
  D. DNS Security, Threat Prevention, and Advanced WildFire with PAN-OS 9.x
  B. Advanced Threat Prevention and PAN-OS 10.2

  ---

  Explanation

  Cobalt Strike is a popular post-exploitation framework often used by attackers for Command and Control (C2) operations. Malleable C2 profiles allow attackers to modify the behavior of their C2 communication, making detection more difficult.

  Stopping these attacks in real time requires deep inline inspection and the ability to block zero-day and evasive threats.

  Why "Advanced Threat Prevention and PAN-OS 10.2" (Correct Answer B)?Advanced Threat Prevention (ATP) on PAN-OS 10.2 uses inline deep learning models to detect and block Cobalt Strike Malleable C2 attacks in real time. ATP is

  designed to prevent evasive techniques and zero-day threats, which is essential for blocking Malleable C2. PAN-OS 10.2 introduces enhanced capabilities for detecting malicious traffic patterns and inline analysis of encrypted traffic.

  ATP examines traffic behavior and signature-less threats, effectively stopping evasive C2 profiles.

  PAN-OS 10.2 includes real-time protections specifically for Malleable C2. Why not "Next-Generation CASB on PAN-OS 10.1" (Option A)?Next-Generation CASB (Cloud Access Security Broker) is designed to secure SaaS applications and does not provide the inline C2 protection required to stop Malleable C2

  attacks. CASB is not related to Command and Control detection.

  Why not "Threat Prevention and Advanced WildFire with PAN-OS 10.0" (Option C)?Threat Prevention and Advanced WildFire are effective for detecting and preventing malware and known threats. However, they rely heavily on signatures

  and sandboxing for analysis, which is not sufficient for stopping real-time evasive C2 traffic . PAN-OS 10.0 lacks the advanced inline capabilities provided by ATP in PAN-OS 10.2. Why not "DNS Security, Threat Prevention, and Advanced WildFire with PAN-OS 9.x" (Option D)?While DNS Security and Threat Prevention are valuable for blocking malicious domains and known threats, PAN-OS 9.x does not provide the

  inline deep learning capabilities needed for real-time detection and prevention of Malleable C2 attacks. The absence of advanced behavioral analysis in PAN- OS 9.x makes this combination ineffective against advanced C2 attacks.

• Question 12:

  Which use case is valid for Palo Alto Networks Next-Generation Firewalls (NGFWs)?

  A. Code-embedded NGFWs provide enhanced internet of things (IoT) security by allowing PAN-OS code to be run on devices that do not support embedded virtual machine (VM) images.
  B. Serverless NGFW code security provides public cloud security for code-only deployments that do not leverage virtual machine (VM) instances or containerized services.
  C. IT/OT segmentation firewalls allow operational technology resources in plant networks to securely interface with IT resources in the corporate network.
  D. PAN-OS GlobalProtect gateways allow companies to run malware and exploit prevention modules on their endpoints without installing endpoint agents.
  C. IT/OT segmentation firewalls allow operational technology resources in plant networks to securely interface with IT resources in the corporate network.

  ---

  Explanation

  Palo Alto Networks Next-Generation Firewalls (NGFWs) provide robust security features across a variety of use cases. Let's analyze each option:

  A. Code-embedded NGFWs provide enhanced IoT security by allowing PAN-OS code to be run on devices that do not support embedded VM images.

  This statement is incorrect. NGFWs do not operate as "code-embedded" solutions for IoT devices. Instead, they protect IoT devices through advanced threat prevention, device identification, and segmentation capabilities.

  B. Serverless NGFW code security provides public cloud security for code-only deployments that do not leverage VM instances or containerized services.

  This is not a valid use case. Palo Alto NGFWs provide security for public cloud environments using VM- series firewalls, CN-series (containerized firewalls), and Prisma Cloud for securing serverless architectures. NGFWs do not operate in

  "code-only" environments.

  C. IT/OT segmentation firewalls allow operational technology (OT) resources in plant networks to securely interface with IT resources in the corporate network.

  This is a valid use case. Palo Alto NGFWs are widely used in industrial environments to provide IT/OT segmentation, ensuring that operational technology systems in plants or manufacturing facilities can securely communicate with IT

  networks while protecting against cross-segment threats. Features like App-ID, User- ID, and Threat Prevention are leveraged for this segmentation.

  D. PAN-OS GlobalProtect gateways allow companies to run malware and exploit prevention modules on their endpoints without installing endpoint agents.

  This is incorrect. GlobalProtect gateways provide secure remote access to corporate networks and extend the NGFW's threat prevention capabilities to endpoints, but endpoint agents are required to enforce malware and exploit prevention

  modules.

  Key Takeaways:

  IT/OT segmentation with NGFWs is a real and critical use case in industries like manufacturing and utilities.

  The other options describe features or scenarios that are not applicable or valid for NGFWs.

• Question 13:

  Which statement applies to the default configuration of a Palo Alto Networks NGFW?

  A. Security profiles are applied to all policies by default, eliminating implicit trust of any data traversing the firewall.
  B. The default policy action for intrazone traffic is deny, eliminating implicit trust within a security zone.
  C. The default policy action allows all traffic unless explicitly denied.
  D. The default policy action for interzone traffic is deny, eliminating implicit trust between security zones.
  D. The default policy action for interzone traffic is deny, eliminating implicit trust between security zones.

  ---

  Explanation

  The default configuration of a Palo Alto Networks NGFW includes a set of default security rules that determine how traffic is handled when no explicit rules are defined. Here's the explanation for each option:

  Option A: Security profiles are applied to all policies by default, eliminating implicit trust of any data traversing the firewall Security profiles (such as Antivirus, Anti-Spyware, and URL Filtering) are not applied to any policies by default.

  Administrators must explicitly apply them to security rules.

  This statement is incorrect.

  Option B: The default policy action for intrazone traffic is deny, eliminating implicit trust within a security zone

  By default, traffic within the same zone (intrazone traffic) is allowed . For example, traffic between devices in the "trust" zone is permitted unless explicitly denied by an administrator.

  This statement is incorrect.

  Option C: The default policy action allows all traffic unless explicitly denied

  Palo Alto Networks firewalls do not have an "allow all" default rule. Instead, they include a default "deny all" rule for interzone traffic and an implicit "allow" rule for intrazone traffic.

  This statement is incorrect.

  Option D: The default policy action for interzone traffic is deny, eliminating implicit trust between security zones

  By default, traffic between different zones (interzone traffic) is denied. This aligns with the principle of zero trust, ensuring that no traffic is implicitly allowed between zones. Administrators must define explicit rules to allow interzone traffic.

  This statement is correct.

• Question 14:

  In addition to Advanced DNS Security, which three Cloud-Delivered Security Services (CDSS) subscriptions utilize inline machine learning (ML)? (Choose three)

  A. Enterprise DLP Advanced URL Filtering
  B. Advanced WildFire
  C. Advanced Threat Prevention
  D. IoT Security
  A. Enterprise DLP Advanced URL Filtering
  B. Advanced WildFire
  D. IoT Security

  ---

  Explanation

  To answer this question, let's analyze each Cloud-Delivered Security Service (CDSS) subscription and its role in inline machine learning (ML). Palo Alto Networks leverages inline ML capabilities across several of its subscriptions to provide real-time protection against advanced threats and reduce the need for manual intervention.

  A. Enterprise DLP (Data Loss Prevention)

  Enterprise DLP is a Cloud-Delivered Security Service that prevents sensitive data from being exposed. Inline machine learning is utilized to accurately identify and classify sensitive information in real-time, even when traditional data patterns

  or signatures fail to detect them. This service integrates seamlessly with Palo Alto firewalls to mitigate data exfiltration risks by understanding content as it passes through the firewall.

  B. Advanced URL Filtering

  Advanced URL Filtering uses inline machine learning to block malicious URLs in real-time. Unlikelegacy URL filtering solutions, which rely on static databases, Palo Alto Networks' Advanced URL Filtering leverages ML to identify and stop

  new malicious URLs that have not yet been categorized in static databases. This proactive approach ensures that organizations are protected against emerging threats like phishing and malware-hosting websites.

  C. Advanced WildFire

  Advanced WildFire is a cloud-based sandboxing solution designed to detect and prevent zero-day malware. While Advanced WildFire is a critical part of Palo Alto Networks' security offerings, it primarily uses static and dynamic analysis rather than inline machine learning. The ML-based analysis in Advanced WildFire happens after a file is sent to the cloud for processing, rather than inline, so it does not qualify under this question's scope.

  D. Advanced Threat Prevention

  Advanced Threat Prevention (ATP) uses inline machine learning to analyze traffic in real-time and block sophisticated threats such as unknown command-and-control (C2) traffic. This service replaces the traditional Intrusion Prevention

  System (IPS) approach by actively analyzing network traffic and blocking malicious payloads inline. The inline ML capabilities ensure ATP can detect and block threats that rely on obfuscation and evasion techniques.

  E. IoT Security

  IoT Security is focused on discovering and managing IoT devices connected to the network. While this service uses machine learning for device behavior profiling and anomaly detection, it does not leverage inline machine learning for real-

  time traffic inspection. Instead, it operates at a more general level by providing visibility and identifying device risks.

  Key Takeaways:

  Enterprise DLP, Advanced URL Filtering, and Advanced Threat Prevention all rely on inline machine learning to provide real-time protection.

  Advanced WildFire uses ML but not inline; its analysis is performed in the cloud.

  IoT Security applies ML for device management rather than inline threat detection.

• Question 15:

  A systems engineer (SE) has joined a team to work with a managed security services provider (MSSP) that is evaluating PAN-OS for edge connections to their customer base. The MSSP is concerned about how to efficiently handle routing with all of its customers, especially how to handle BGP peering, because it has created a standard set of rules and settings that it wants to apply to each customer, as well as to maintain and update them. The solution requires logically separated BGP peering setups for each customer. What should the SE do to increase the probability of Palo Alto Networks being awarded the deal?

  A. Work with the MSSP to plan for the enabling of logical routers in the PAN-OS Advanced Routing Engine to allow sharing of routing profiles across the logical routers.
  B. Collaborate with the MSSP to create an API call with a standard set of routing filters, maps, and related actions, then the MSSP can call the API whenever they bring on a new customer.
  C. Confirm to the MSSP that the existing virtual routers will allow them to have logically separated BGP peering setups, but that there is no method to handle the standard criteria across all of the routers.
  D. Establish with the MSSP the use of vsys as the better way to segregate their environment so that customer data does not intermingle.
  A. Work with the MSSP to plan for the enabling of logical routers in the PAN-OS Advanced Routing Engine to allow sharing of routing profiles across the logical routers.

  ---

  Explanation

  To address the MSSP's requirement for logically separated BGP peering setups while efficiently managing standard routing rules and updates, Palo Alto Networks offers the Advanced Routing Engine introduced in PAN-OS 11.0. The

  Advanced Routing Engine enhances routing capabilities, including support forlogical routers , which is critical in this scenario.

  Why A is Correct

  Logical routers enable the MSSP to create isolated BGP peering configurations for each customer.

  The Advanced Routing Engine allows the MSSP to share standard routing profiles (such as filters, policies, or maps) across logical routers, simplifying the deployment and maintenance of routing configurations.

  This approach ensures scalability, as each logical router can handle the unique needs of a customer while leveraging shared routing rules. Why Other Options Are Incorrect

  B:While using APIs to automate deployment is beneficial, it does not solve the need for logically separated BGP peering setups. Logical routers provide this separation natively.

  C:While virtual routers in PAN-OS can separate BGP peering setups, they do not support the efficient sharing of standard routing rules and profiles across multiple routers.

  D:Virtual systems (vsys) are used to segregate administrative domains, not routing configurations. Vsys is not the appropriate solution for managing BGP peering setups across multiple customers. Key Takeaways:

  PAN-OS Advanced Routing Engine with logical routers simplifies BGP peering management for MSSPs.

  Logical routers provide the separation required for customer environments while enabling shared configuration profiles.

• Question 16:

  While a quote is being finalized for a customer that is purchasing multiple PA-5400 series firewalls, the customer specifies the need for protection against zero-day malware attacks. Which Cloud-Delivered Security Services (CDSS) subscription add-on license should be included in the quote?

  A. AI Access Security
  B. Advanced Threat Prevention
  C. Advanced WildFire
  D. App-ID
  C. Advanced WildFire

  ---

  Explanation

  Zero-day malware attacks are sophisticated threats that exploit previously unknown vulnerabilities or malware signatures. To provide protection against such attacks, the appropriate Cloud-Delivered Security Service subscription must be

  included.

  Why "Advanced WildFire" (Correct Answer C)?Advanced WildFire is Palo Alto Networks' sandboxing solution that identifies and prevents zero-day malware. It uses machine learning, dynamic analysis, and static analysis to detect unknown

  malware in real time.

  Files and executables are analyzed in the cloud-based sandbox, and protections are shared globally within minutes.

  Advanced WildFire specifically addresses zero-day threats by dynamically analyzing suspicious files and generating new signatures.

  Why not "AI Access Security" (Option A)?AI Access Security is designed to secure SaaS applications by monitoring and enforcing data protection and compliance. While useful for SaaS security, it does not focus on detecting or preventing

  zero-day malware.

  Why not "Advanced Threat Prevention" (Option B)?Advanced Threat Prevention (ATP) focuses on detecting zero-day exploits (e.g., SQL injection, buffer overflows) using inline deep learning but is not specifically designed to analyze and

  prevent zero-day malware. ATP complements Advanced WildFire, but WildFire is the primary solution for malware detection.

  Why not "App-ID" (Option D)?App-ID identifies and controls applications on the network. While it improves visibility and security posture, it does not address zero-day malware detection or prevention.

• Question 17:

  The efforts of a systems engineer (SE) with an industrial mining company account have yielded interest in Palo Alto Networks as part of its effort to incorporate innovative design into operations using robots and remote-controlled vehicles in dangerous situations. A discovery call confirms that the company will receive control signals to its machines over a private mobile network using radio towers that connect to cloud-based applications that run the control programs. Which two sets of solutions should the SE recommend?

  A. That 5G Security be enabled and architected to ensure the cloud computing is not compromised in the commands it is sending to the onsite machines.
  B. That Cloud NGFW be included to protect the cloud-based applications from external access into the cloud service provider hosting them.
  C. That IoT Security be included for visibility into the machines and to ensure that other devices connected to the network are identified and given risk and behavior profiles.
  D. That an Advanced CDSS bundle (Advanced Threat Prevention, Advanced WildFire, and Advanced URL Filtering) be procured to ensure the design receives advanced protection.
  A. That 5G Security be enabled and architected to ensure the cloud computing is not compromised in the commands it is sending to the onsite machines.
  C. That IoT Security be included for visibility into the machines and to ensure that other devices connected to the network are identified and given risk and behavior profiles.

  ---

  Explanation

  5G Security (Answer A):

  In this scenario, the mining company operates on a private mobile network, likely powered by5G technology to ensure low latency and high bandwidth for controlling robots and vehicles.

  Palo Alto Networks 5G Security is specifically designed to protect private mobile networks. It prevents exploitation of vulnerabilities in the 5G infrastructure and ensures the control signals sent to the machines are not compromised by

  attackers.

  Key features include network slicing protection, signaling plane security, and secure user plane communications.

  IoT Security (Answer C):

  The mining operation depends on machines and remote-controlled vehicles, which are IoT devices.

  Palo Alto Networks IoT Security provides:

  Full device visibilityto detect all IoT devices (such as robots, remote vehicles, or sensors).

  Behavioral analysisto create risk profiles and identify anomalies in the machines' operations.

  This ensures a secure environment for IoT devices, reducing the risk of a device being exploited.

  Why Not Cloud NGFW (Answer B):

  While Cloud NGFW is critical for protecting cloud-based applications, the specific concern here is protecting control signals and IoT devices rather than external access into the cloud service.

  The private mobile network and IoT device protection requirements make 5G Security and IoT Security more relevant.

  Why Not Advanced CDSS Bundle (Answer D):

  The Advanced CDSS bundle (Advanced Threat Prevention, Advanced WildFire, Advanced URL Filtering) is essential for securing web traffic and detecting threats, but it does not address the specific challenges of securing private mobile

  networks and IoT devices .

  While these services can supplement the design, they are not the primary focus in this use case. References from Palo Alto Networks Documentation:

• Question 18:

  Which statement appropriately describes performance tuning Intrusion Prevention System (IPS) functions on a Palo Alto Networks NGFW running Advanced Threat Prevention?

  A. Leave all signatures turned on because they do not impact performance.
  B. Create a new threat profile to use only signatures needed for the environment.
  C. Work with TAC to run a debug and receive exact measurements of performance utilization for the IPS.
  D. To increase performance, disable any threat signatures that do not apply to the environment.
  B. Create a new threat profile to use only signatures needed for the environment.

  ---

  Explanation

  Create a New Threat Profile (Answer B):

  Performance tuning in Intrusion 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 create custom threat profiles to 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 by creating a new threat profile . Manually disabling signatures one by one is not scalable or efficient. References from Palo Alto

• Question 19:

  Which technique is an example of a DNS attack that Advanced DNS Security can detect and prevent?

  A. High entropy DNS domains
  B. Polymorphic DNS
  C. CNAME cloaking
  D. DNS domain rebranding
  A. High entropy DNS domains

  ---

  Explanation

  Advanced DNS Security on Palo Alto Networks firewalls is designed to identify and prevent a wide range of DNS-based attacks. Among the listed options, "High entropy DNS domains" is a specific example of a DNS attack that Advanced DNS Security can detect and block. Why "High entropy DNS domains" (Correct Answer A)?High entropy DNS domains are often used in attacks where randomly generated domain names (e.g., gfh34ksdu.com) are utilized by malware or bots to evade detection. This is a hallmark of Domain Generation Algorithms (DGA)-based attacks. Palo Alto Networks firewalls with Advanced DNS Security use machine learning to detect such domains by analyzing the entropy (randomness) of DNS queries. High entropy values indicate the likelihood of a dynamically generated or malicious domain. Why not "Polymorphic DNS" (Option B)?While polymorphic DNS refers to techniques that dynamically change DNS records to avoid detection, it is not specifically identified as an attack type mitigated by Advanced DNS Security in Palo Alto Networks documentation. The firewall focuses more on the behavior of DNS queries, such as detecting DGA domains or anomalous DNS traffic patterns. Why not "CNAME cloaking" (Option C)?CNAME cloaking involves using CNAME records to redirect DNS queries to malicious or hidden domains. Although Palo Alto firewalls may detect and block malicious DNS redirections, the focus of Advanced DNS Security is primarily on identifying patterns of DNS abuse like DGA domains, tunneling, or high entropy queries. Why not "DNS domain rebranding" (Option D)?DNS domain rebranding involves changing the domain names associated with malicious activity to evade detection. This is typically a tactic used for persistence but is not an example of a DNS attack type specifically addressed by Advanced DNS Security. Advanced DNS Security focuses on dynamic, real-time identification of suspicious DNS patterns, such as high entropy domains, DNS tunneling, or protocol violations. High entropy DNS domains are directly tied to attack mechanisms like DGAs, making this the correct answer.

• Question 20:

  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. Recommend that the operations team use the free machine learning-powered AIOps for NGFW tool.
  B. Suggest the inclusion of training into the proposal so that the operations team is informed andconfident in working on their firewalls.
  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.
  D. Propose AIOps Premium within Strata Cloud Manager (SCM) to address the company's issues from within the existing technology.
  A. Recommend that the operations team use the free machine learning-powered AIOps for NGFW tool.
  D. Propose AIOps Premium within Strata Cloud Manager (SCM) to address the company's issues from within the existing technology.

  ---

  Explanation

  Free AIOps for NGFW Tool (Answer A):

  The free AIOps for NGFW tool uses machine learning-powered analytics to monitor firewall performance, detect potential capacity issues, and provide insights for proactive management.

  This tool helps operations teamsidentify capacity thresholds, performance bottlenecks, and configuration issues , reducing the reliance on manual expertise for routine tasks.

  By using AIOps, the customer can avoid rushed upgrade projects in the future, as the tool provides predictive insights and recommendations for capacity planning.

  AIOps Premium within Strata Cloud Manager (Answer D):

  AIOps Premiumis a paid version available within Strata Cloud Manager (SCM), offering more advanced analytics and proactive monitoring capabilities.

  It helps address operational challenges by automating workflows and ensuring the health and performance of NGFWs , minimizing the need for constant manual intervention.

  This aligns with the CIO's goal of freeing up the operations team for more valuable business tasks.

  Why Not B:

  While training may help the operations team gain confidence, the long-term focus should be on reducing their manual workload by providing automated tools like AIOps. The CIO's concern indicates that relying on manual expertise for

  ongoing maintenance is not a scalable solution.

  Why Not C:

  Simply informing the CIO about enhanced features from a PAN-OS upgrade does not address the capacity planning issues or reduce the dependency on the operations team for manual issue resolution. References from Palo Alto Networks
