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

• Question 21:

  A company with a large Active Directory (AD) of over 20,000 groups has user roles based on group membership in the directory. Up to 1,000 groups may be used in Security policies. The company has limited operations personnel and wants

  to reduce the administrative overhead of managing the synchronization of the groups with their firewalls.

  What is the recommended architecture to synchronize the company's AD with Palo Alto Networks firewalls?

  A. Configure a group mapping profile with custom filters for LDAP attributes that are mapped to the user roles.
  B. Configure a group mapping profile, without a filter, to synchronize all groups.
  C. Configure a group mapping profile with an include group list.
  D. Configure NGFWs to synchronize with the AD after deploying the Cloud Identity Engine (CIE) and agents.
  C. Configure a group mapping profile with an include group list.

  ---

  Explanation

  Synchronizing a large Active Directory (AD) with over 20,000 groups can introduce significant overhead if all groups are synchronized, especially when only a subset of groups (e.g., 1,000 groups) are required for Security policies. The most

  efficient approach is to configure agroupmapping profile with an include group list to minimize unnecessary synchronization and reduce administrative overhead.

  Why "Configure a group mapping profile with an include group list" (Correct Answer C)?Using a group mapping profile with an include group list ensures that only the required 1,000 groups are synchronized with the firewall. This approach:

  Reduces the load on the firewall's User-ID process by limiting the number of synchronized groups.

  Simplifies management by focusing on the specific groups relevant to Security policies.

  Avoids synchronizing the entire directory (20,000 groups), which would be inefficient and resource-intensive.

  Why not "Configure a group mapping profile, without a filter, to synchronize all groups" (Option B)?Synchronizing all 20,000 groups would unnecessarily increase administrative and resource overhead. This approach contradicts the

  requirement to reduce administrative burden.

  Why not "Configure a group mapping profile with custom filters for LDAP attributes that are mapped to the user roles" (Option A)?While filtering LDAP attributes can be useful, this approach is more complex to implement and manage

  compared to an include group list. It does not directly address the problem of limiting synchronization to a specific subset of groups. Why not "Configure NGFWs to synchronize with the AD after deploying the Cloud Identity Engine (CIE) and

  agents" (Option D)?While the Cloud Identity Engine (CIE) is a modern solution for user and group mapping, it is unnecessary in this scenario. A traditional group mapping profile with an include list is sufficient and simpler to implement. CIE is

  typically used for complex hybrid or cloud environments.

• Question 22:

  Which three known variables can assist with sizing an NGFW appliance? (Choose three.)

  A. Connections per second
  B. Max sessions
  C. Packet replication
  D. App-ID firewall throughput
  E. Telemetry enabled
  A. Connections per second
  B. Max sessions
  D. App-ID firewall throughput

  ---

  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.

• Question 23:

  A systems engineer should create a profile that blocks which category to protect a customer from ransomware URLs by using Advanced URL Filtering?

  A. Ransomware
  B. High Risk
  C. Scanning Activity
  D. Command and Control
  A. Ransomware

  ---

  Explanation

  When configuring Advanced URL Filtering on a Palo Alto Networks firewall, the "Ransomware" category should be explicitly blocked to protect customers from URLs associated with ransomware activities. Ransomware URLs typically host malicious code or scripts designed to encrypt user data and demand a ransom. By blocking the "Ransomware" category, systems engineers can proactively prevent users from accessing such URLs. Why "Ransomware" (Correct Answer A)? The "Ransomware" category is specifically curated by Palo Alto Networks to include URLs known to deliver ransomware or support ransomware operations. Blocking this category ensures that any URL categorized as part of this list will be inaccessible to end- users, significantly reducing the risk of ransomware attacks. Why not "High Risk" (Option B)?While the "High Risk" category includes potentially malicious sites, it is broader and less targeted. It may not always block ransomware-specific URLs. "High Risk" includes a range of websites that are flagged based on factors like bad reputation or hosting malicious content in general. It is less focused than the "Ransomware" category. Why not "Scanning Activity" (Option C)?The "Scanning Activity" category focuses on URLs used in vulnerability scans, automated probing, or reconnaissance by attackers. Although such activity could be a precursor to ransomware attacks, it does not directly block ransomware URLs.

  Why not "Command and Control" (Option D)?The "Command and Control" category is designed to block URLs used by malware or compromised systems to communicate with their operators. While some ransomware may utilize

  commandand-control (C2) servers, blocking C2 URLs alone does not directly target ransomware URLs themselves.

  By using the Advanced URL Filtering profile and blocking the "Ransomware" category, the firewall applies targeted controls to mitigate ransomware-specific threats.

• Question 24:

  When a customer needs to understand how Palo Alto Networks NGFWs lower the risk of exploitation by newly announced vulnerabilities known to be actively attacked, which solution and functionality delivers the most value?

  A. Advanced URL Filtering uses machine learning (ML) to learn which malicious URLs are being utilized by the attackers, then block the resulting traffic.
  B. Advanced Threat Prevention's command injection and SQL injection functions use inline deep learning against zero-day threats.
  C. Single Pass Architecture and parallel processing ensure traffic is efficiently scanned against any enabled Cloud-Delivered Security Services (CDSS) subscription.
  D. WildFire loads custom OS images to ensure that the sandboxing catches any activity that would affect the customer's environment.
  B. Advanced Threat Prevention's command injection and SQL injection functions use inline deep learning against zero-day threats.

  ---

  Explanation

  The most effective way to reduce the risk of exploitation by newly announced vulnerabilities is through Advanced Threat Prevention (ATP) . ATP uses inline deep learning to identify and block exploitation attempts, even for zero-day

  vulnerabilities, in real time.

  Why "Advanced Threat Prevention's command injection and SQL injection functions use inline deep learning against zero-day threats" (Correct Answer B)?Advanced Threat Prevention leverages deep learning models directly in the data path,

  which allows it to analyze traffic in real time and detect patterns of exploitation, including newly discovered vulnerabilities being actively exploited in the wild.

  It specifically targets advanced tactics like:

  Command injection.

  SQL injection.

  Memory-based exploits.

  Protocol evasion techniques.

  This functionality lowers the risk of exploitation by actively blocking attack attempts based on their behavior, even when a signature is not yet available. This approach makes ATP the most valuable solution for addressing new and actively

  exploited vulnerabilities.

  Why not "Advanced URL Filtering uses machine learning (ML) to learn which malicious URLs are being utilized by the attackers, then block the resulting traffic" (Option A)?While Advanced URL Filtering is highly effective at blocking access to

  malicious websites, it does not provide the inline analysis necessary to prevent direct exploitation of vulnerabilities. Exploitation often happens within the application or protocol layer, which Advanced URL Filtering does not inspect. Why not

  "Single Pass Architecture and parallel processing ensure traffic is efficiently scanned against any enabled Cloud-Delivered Security Services (CDSS) subscription" (Option C)?Single Pass Architecture improves performance by ensuring all

  enabled services (like Threat Prevention, URL Filtering, etc.) process traffic efficiently. However, it is not a feature that directly addresses vulnerability exploitation or zero-day attack detection. Why not "WildFire loads custom OS images to

  ensure that the sandboxing catches anyactivity that would affect the customer's environment" (Option D)?WildFire is a sandboxing solution designed to detect malicious files and executables. While it is useful for analyzing malware, it does

  not provide inline protection against exploitation of newly announced vulnerabilities, especially those targeting network protocols or applications.

• Question 25:

  A security engineer has been tasked with protecting a company's on-premises web servers but is not authorized to purchase a web application firewall (WAF).

  Which Palo Alto Networks solution will protect the company from SQL injection zero-day, command injection zero-day, Cross-Site Scripting (XSS) attacks, and IIS exploits?

  A. Threat Prevention and PAN-OS 11.x
  B. Advanced Threat Prevention and PAN-OS 11.x
  C. Threat Prevention, Advanced URL Filtering, and PAN-OS 10.2 (and higher)
  D. Advanced WildFire and PAN-OS 10.0 (and higher)
  B. Advanced Threat Prevention and PAN-OS 11.x

  ---

  Explanation

  Protecting web servers from advanced threats like SQL injection, command injection, XSS attacks, and IIS exploits requires a solution capable of deep packet inspection, behavioral analysis, and inline prevention of zero-day attacks. The most effective solution here is Advanced Threat Prevention (ATP) combined with PAN-OS 11.x . Why "Advanced Threat Prevention and PAN-OS 11.x" (Correct Answer B)?Advanced Threat Prevention (ATP) enhances traditional threat prevention by using inline deep learning models to detect and block advanced zero-day threats, including SQL injection, command injection, and XSS attacks . With PAN-OS 11.x, ATP extends its detection capabilities to detect unknown exploits without relying on signature-based methods. This functionality is critical for protecting web servers in scenarios where a dedicated WAF is unavailable.

  ATP provides the following benefits:

  Inline prevention of zero-day threats using deep learning models.

  Real-time detection of attacks like SQL injection and XSS.

  Enhanced protection for web server platforms like IIS.

  Full integration with the Palo Alto Networks Next-Generation Firewall (NGFW).

  Why not "Threat Prevention and PAN-OS 11.x" (Option A)?Threat Prevention relies primarily on signature-based detection for known threats. While it provides basic protection, it lacks the capability to block zero-day attacks using advanced

  methods like inline deep learning. For zero-day SQL injection and XSS attacks, Threat Prevention alone is insufficient. Why not "Threat Prevention, Advanced URL Filtering, and PAN-OS 10.2 (and higher)" (Option C)?While this combination

  includes Advanced URL Filtering (useful for blocking malicious URLs associated with exploits), it still relies on Threat Prevention , which is signature-based. This combination does not provide the zero-day protection needed for advanced

  injection attacks or XSS vulnerabilities. Why not "Advanced WildFire and PAN-OS 10.0 (and higher)" (Option D)?Advanced WildFire is focused on analyzing files and executables in a sandbox environment to identify malware. While it is

  excellent for identifying malware, it is not designed to provide inline prevention for web-based injection attacks or XSS exploits targeting web servers.

• Question 26:

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

  ---

  Explanation

  Segregating a network into unique BGP environments requires the ability to configure separateeBGP autonomous systems (AS) within the NGFW. Palo Alto Networks firewalls support advanced BGP features, including the ability to create

  and manage multiple autonomous systems.

  Why "It can be addressed by creating multiple eBGP autonomous systems" (Correct Answer B)? PAN-OS supports the configuration of multiple eBGP AS environments. By creating unique eBGP AS numbers for different parts of the network,

  traffic can be segregated and routed separately. This feature is commonly used in multi-tenant environments or networks requiring logical separation for administrative or policy reasons.

  Each eBGP AS can maintain its own routing policies, neighbors, and traffic segmentation.

  This approach allows the NGFW to address the customer's need for segregated internal BGP environments.

  Why not "It cannot be addressed because PAN-OS does not support it" (Option A)?This statement is incorrect because PAN-OS fully supports BGP, including eBGP, iBGP, and features like route reflectors, confederations, and autonomous

  systems.

  Why not "It can be addressed with BGP confederations" (Option C)?While BGP confederations can logically group AS numbers within a single AS, they are generally used to simplify iBGP designs in very large-scale networks. They are not

  commonly used for segregating internal environments and are not required for the described use case. Why not "It cannot be addressed because BGP must be fully meshed internally to work" (Option D)?Full mesh iBGP is only required in

  environments without route reflectors. The described scenario does not mention the need for iBGP full mesh; instead, it focuses on segregated environments, which can be achieved with eBGP.

• Question 27:

  A prospective customer is concerned about stopping data exfiltration, data infiltration, and command-and- control (C2) activities over port 53. Which subscription(s) should the systems engineer recommend?

  A. Threat Prevention
  B. App-ID and Data Loss Prevention
  C. DNS Security
  D. Advanced Threat Prevention and Advanced URL Filtering
  C. DNS Security

  ---

  Explanation

  DNS Security (Answer C):

  DNS Securityis the appropriate subscription for addressing threats over port 53 .

  DNS tunneling is a common method used for data exfiltration, infiltration, and C2 activities , as it allows malicious traffic to be hidden within legitimate DNS queries.

  The DNS Security service applies machine learning models to analyze DNSqueries in real-time, block malicious domains, and prevent tunneling activities.

  It integrates seamlessly with the NGFW, ensuring advanced protection against DNS-based threats without requiring additional infrastructure.

  Why Not Threat Prevention (Answer A):

  Threat Prevention is critical for blocking malware, exploits, and vulnerabilities, but it does not specifically address DNS-based tunneling or C2 activities over port 53. Why Not App-ID and Data Loss Prevention (Answer B):

  While App-ID can identify applications, and Data Loss Prevention (DLP) helps prevent sensitive data leakage, neither focuses on blocking DNS tunneling or malicious activity over port 53. Why Not Advanced Threat Prevention and Advanced URL Filtering (Answer D):

  Advanced Threat Prevention and URL Filtering are excellent for broader web and network threats, but DNS tunneling specifically requires the DNS Security subscription , which specializes in DNS-layer threats. References from Palo Alto

• Question 28:

  A company has multiple business units, each of which manages its own user directories and identity providers (IdPs) with different domain names. The company's network security team wants to deploy a shared GlobalProtect remote access

  service for all business units to authenticate users to each business unit's IdP.

  Which configuration will enable the network security team to authenticate GlobalProtect users to multiple SAML IdPs?

  A. GlobalProtect with multiple authentication profiles for each SAML IdP
  B. Multiple authentication mode Cloud Identity Engine authentication profile for use on the GlobalProtect portals and gateways
  C. Authentication sequence that has multiple authentication profiles using different authentication methods
  D. Multiple Cloud Identity Engine tenants for each business unit
  A. GlobalProtect with multiple authentication profiles for each SAML IdP

  ---

  Explanation

  To configure GlobalProtect to authenticate users from multiple SAML identity providers (IdPs), the correct approach involves creating multiple authentication profiles, one for each IdP. Here's the analysis of each option:

  Option A: GlobalProtect with multiple authentication profiles for each SAML IdP

  GlobalProtect allows configuring multiple SAML authentication profiles, each corresponding to a specific IdP.

  These profiles are associated with the GlobalProtect portal or gateway. When users attempt to authenticate, they can be directed to the appropriate IdP based on their domain or other attributes.

  This is the correct approach to enable authentication for users from multiple IdPs.

  Option B: Multiple authentication mode Cloud Identity Engine authentication profile for use on the GlobalProtect portals and gateways

  The Cloud Identity Engine (CIE) can synchronize identities from multiple directories, but it does not directly support multiple SAML IdPs for a shared GlobalProtect setup.

  This option is not applicable.

  Option C: Authentication sequence that has multiple authentication profiles using different authentication methods

  Authentication sequences allow multiple authentication methods (e.g., LDAP, RADIUS, SAML) to be tried in sequence for the same user, but they are not designed for handling multiple SAML IdPs.

  This option is not appropriate for the scenario.

  Option D: Multiple Cloud Identity Engine tenants for each business unit

  Deploying multiple CIE tenants for each business unit adds unnecessary complexity and is not required for configuring GlobalProtect to authenticate users to multiple SAML IdPs.

  This option is not appropriate.

• Question 29:

  Which two statements clarify the functionality and purchase options for Palo Alto Networks AIOps for NGFW? (Choose two.)

  A. It is offered in two license tiers: a commercial edition and an enterprise edition.
  B. It is offered in two license tiers: a free version and a premium version.
  C. It uses telemetry data to forecast, preempt, or identify issues, and it uses machine learning (ML) to adjust and enhance the process.
  D. It forwards log data to Advanced WildFire to anticipate, prevent, or identify issues, and it uses machine learning (ML) to refine and adapt to the process.
  B. It is offered in two license tiers: a free version and a premium version.
  C. It uses telemetry data to forecast, preempt, or identify issues, and it uses machine learning (ML) to adjust and enhance the process.

  ---

  Explanation

  Palo Alto Networks AIOps for NGFW is a cloud-delivered service that leverages telemetry data and machine learning (ML) to provide proactive operational insights, best practice recommendations, and issue prevention.

  Why "It is offered in two license tiers: a free version and a premium version" (Correct Answer B)?AIOps for NGFW is available in two tiers:

  Free Tier:Provides basic operational insights and best practices at no additional cost.

  Premium Tier:Offers advanced capabilities, such as AI-driven forecasts, proactive issue prevention, and enhanced ML-based recommendations.

  Why "It uses telemetry data to forecast, preempt, or identify issues, and it uses machine learning (ML) to adjust and enhance the process" (Correct Answer C)?AIOps uses telemetry data from NGFWs to analyze operational trends, forecast

  potential problems, and recommend solutions before issues arise. ML continuously refines these insights by learning from real-world data, enhancing accuracy and effectiveness over time.

  Why not "It is offered in two license tiers: a commercial edition and an enterprise edition" (Option A)?This is incorrect because the licensing model for AIOps is based on "free" and "premium" tiers, not "commercial" and "enterprise" editions.

  Why not "It forwards log data to Advanced WildFire to anticipate, prevent, or identify issues, and it uses machine learning (ML) to refine and adapt to the process" (Option D)?AIOps does not rely on Advanced WildFire for its operation.

  Instead, it uses telemetry data directly from the NGFWs to perform operational and security analysis.

• Question 30:

  Which action can help alleviate a prospective customer's concerns about transitioning from a legacy firewall with port-based policies to a Palo Alto Networks NGFW with application-based policies?

  A. Discuss the PAN-OS Policy Optimizer feature as a means to safely migrate port-based rules to application-based rules.
  B. Assure the customer that the migration wizard will automatically convert port-based rules to application- based rules upon installation of the new NGFW.
  C. Recommend deploying a new NGFW firewall alongside the customer's existing port-based firewall until they are comfortable removing the port-based firewall.
  D. Reassure the customer that the NGFW supports the continued use of port-based rules, as PAN-OS automatically translates these policies into application-based policies.
  A. Discuss the PAN-OS Policy Optimizer feature as a means to safely migrate port-based rules to application-based rules.

  ---

  Explanation

  A. Discuss the PAN-OS Policy Optimizer feature as a means to safely migrate port-based rules to application-based rules.

  PAN-OS includes the Policy Optimizer tool, which helps migrate legacy port-based rules to application- based policies incrementally and safely. This tool identifies unused, redundant, or overly permissive rules and suggests optimized policies

  based on actual traffic patterns.

  Why Other Options Are Incorrect

  B:The migration wizard does not automatically convert port-based rules to application-based rules. Migration must be carefully planned and executed using tools like the Policy Optimizer.

  C:Running two firewalls in parallel adds unnecessary complexity and is not a best practice for migration.

  D:While port-based rules are supported, relying on them defeats the purpose of transitioning to application-based security.
