NEW QUESTION # 29
Device-ID can be used in which three policies? (Choose three.)
- A. Security
- B. Quality of Service (QoS)
- C. Policy-based forwarding (PBF)
- D. SD-WAN
- E. Decryption
Answer: A,B,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.
NEW QUESTION # 30
A customer claims that Advanced WildFire miscategorized a file as malicious and wants proof, because another vendor has said that the file is benign.
How could the systems engineer assure the customer that Advanced WildFire was accurate?
- A. Review the threat logs for information to provide to the customer.
- B. Open a TAG ticket for the customer and allow support engineers to determine the appropriate action.
- C. Use the WildFire Analysis Report in the log to show the customer the malicious actions the file took when it was detonated.
- D. Do nothing because the customer will realize Advanced WildFire is right.
Answer: C
Explanation:
Advanced WildFire is Palo Alto Networks' cloud-based malware analysis and prevention solution. It determines whether files are malicious by executing them in a sandbox environment and observing their behavior. To address the customer's concern about the file categorization, the systems engineer must provide evidence of the file's behavior. Here's the analysis of each option:
* Option A: Review the threat logs for information to provide to the customer
* Threat logs can provide a summary of events and verdicts for malicious files, but they do not include the detailed behavior analysis needed to convince the customer.
* While reviewing the logs is helpful as a preliminary step, it does not provide the level of proof the customer needs.
* This option is not sufficient on its own.
* Option B: Use the WildFire Analysis Report in the log to show the customer the malicious actions the file took when it was detonated
* WildFire generates an analysis report that includes details about the file's behavior during detonation in the sandbox, such as network activity, file modifications, process executions, and any indicators of compromise (IoCs).
* This report provides concrete evidence to demonstrate why the file was flagged as malicious. It is the most accurate way to assure the customer that WildFire's decision was based on observed malicious actions.
* This is the best option.
* Option C: Open a TAG ticket for the customer and allow support engineers to determine the appropriate action
* While opening a support ticket is a valid action for further analysis or appeal, it isnot a direct way to assure the customer of the current WildFire verdict.
* This option does not directly address the customer's request for immediate proof.
* This option is not ideal.
* Option D: Do nothing because the customer will realize Advanced WildFire is right
* This approach is dismissive of the customer's concerns and does not provide any evidence to support WildFire's decision.
* This option is inappropriate.

NEW QUESTION # 31
Which two tools should a systems engineer use to showcase the benefit of an evaluation that a customer has just concluded?
- A. Best Practice Assessment (BPA)
- B. Firewall Sizing Guide
- C. Golden Images
- D. Security Lifecycle Review (SLR)
Answer: A,D
Explanation:
After a customer has concluded an evaluation of Palo Alto Networks solutions, it is critical to provide a detailed analysis of the results and benefits gained during the evaluation. The following two tools are most appropriate:
* Why "Best Practice Assessment (BPA)" (Correct Answer A)?The BPA evaluates the customer's firewall configuration against Palo Alto Networks' recommended best practices. It highlights areas where the configuration could be improved to strengthen security posture. This is an excellent tool to showcase how adopting Palo Alto Networks' best practices aligns with industry standards and improves security performance.
* Why "Security Lifecycle Review (SLR)" (Correct Answer B)?The SLR provides insights into the customer's security environment based on data collected during the evaluation. It identifies vulnerabilities, risks, and malicious activities observed in the network and demonstrates how Palo Alto Networks' solutions can address these issues. SLR reports use clear visuals and metrics, making it easier to showcase the benefits of the evaluation.
* Why not "Firewall Sizing Guide" (Option C)?The Firewall Sizing Guide is a pre-sales tool used to recommend the appropriate firewall model based on the customer's network size, performance requirements, and other criteria. It is not relevant for showcasing the benefits of an evaluation.
* Why not "Golden Images" (Option D)?Golden Images refer to pre-configured templates for deploying firewalls in specific use cases. While useful for operational efficiency, they are not tools for demonstrating the outcomes or benefits of a customer evaluation.
Reference: Palo Alto Networks documentation for Best Practice Assessment (BPA) and Security Lifecycle Review (SLR) confirms their role in showcasing evaluation benefits.
NEW QUESTION # 32
Regarding APIs, a customer RFP states: "The vendor's firewall solution must provide an API with an enforcement mechanism to deactivate API keys after two hours." How should the response address this clause?
- A. No - The PAN-OS XML API does not support keys.
- B. No - The API keys can be made, but there is no method to deactivate them based on time.
- C. Yes - The default setting must be changed from no limit to 120 minutes.
- D. Yes - This is the default setting for API keys.
Answer: C
Explanation:
Palo Alto Networks' PAN-OS supports API keys for authentication when interacting with the firewall's RESTful and XML-based APIs. By default, API keys do not have an expiration time set, but the expiration time for API keys can be configured by an administrator to meet specific requirements, such as a time-based deactivation after two hours. This is particularly useful for compliance and security purposes, where API keys should not remain active indefinitely.
Here's an evaluation of the options:
* Option A: This is incorrect because the default setting for API keys does not include an expiration time. By default, API keys are valid indefinitely unless explicitly configured otherwise.
* Option B: This is incorrect because PAN-OS fully supports API keys. The API keys are integral to managing access to the firewall's APIs and provide a secure method for authentication.
* Option C: This is incorrect because PAN-OS does support API key expiration when explicitly configured. While the default is "no expiration," the feature to configure an expiration time (e.g., 2 hours) is available.
* Option D (Correct): The correct response to the RFP clause is that the default API key settings need to be modified to set the expiration time to 120 minutes (2 hours). This aligns with the customer requirement to enforce API key deactivation based on time. Administrators can configure this using the PAN-OS management interface or the CLI.
How to Configure API Key Expiration (Steps):
* Access the Web Interface or CLI on the firewall.
* Navigate to Device > Management > API Key Lifetime Settings (on the GUI).
* Set the desired expiration time (e.g., 120 minutes).
* Alternatively, use the CLI to configure the API key expiration:
set deviceconfig system api-key-expiry <time-in-minutes>
commit
* Verify the configuration using the show command or by testing API calls to ensure the key expires after the set duration.

NEW QUESTION # 33
What is used to stop a DNS-based threat?
- A. Buffer overflow protection
- B. DNS proxy
- C. DNS tunneling
- D. DNS sinkholing
Answer: D
Explanation:
DNS-based threats, such as DNS tunneling, phishing, or malware command-and-control (C2) activities, are commonly used by attackers to exfiltrate data or establish malicious communications. Palo Alto Networks firewalls provide several mechanisms to address these threats, and the correct method is DNS sinkholing.
* Why "DNS sinkholing" (Correct Answer D)?DNS sinkholing redirects DNS queries for malicious domains to an internal or non-routable IP address, effectively preventing communication with malicious domains. When a user or endpoint tries to connect to a malicious domain, the sinkhole DNS entry ensures the traffic is blocked or routed to a controlled destination.
* DNS sinkholing is especially effective for blocking malware trying to contact its C2 server or preventing data exfiltration.
* Why not "DNS proxy" (Option A)?A DNS proxy is used to forward DNS queries from endpoints to an upstream DNS server. While it can be part of a network's DNS setup, it does not actively stop DNS- based threats.
* Why not "Buffer overflow protection" (Option B)?Buffer overflow protection is a method used to prevent memory-related attacks, such as exploiting software vulnerabilities. It is unrelated to DNS- based threat prevention.
* Why not "DNS tunneling" (Option C)?DNS tunneling is itself a type of DNS-based threat where attackers encode malicious traffic within DNS queries and responses. This option refers to the threat itself, not the method to stop it.
Reference: Palo Alto Networks DNS Security documentation confirms that DNS sinkholing is a key mechanism for stopping DNS-based threats.
NEW QUESTION # 34
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. 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.
- B. Recommend that the operations team use the free machine learning-powered AIOps for NGFW tool.
- C. Suggest the inclusion of training into the proposal so that the operations team is informed andconfident in working on their firewalls.
- D. Propose AIOps Premium within Strata Cloud Manager (SCM) to address the company's issues from within the existing technology.
Answer: B,D
Explanation:
* Free AIOps for NGFW Tool (Answer A):
* Thefree AIOps for NGFW toolusesmachine learning-powered analyticsto 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 providespredictive insights and recommendationsfor capacity planning.
* AIOps Premium within Strata Cloud Manager (Answer D):
* AIOps Premiumis a paid version available within Strata Cloud Manager (SCM), offering more advanced analyticsand proactive monitoring capabilities.
* It helps address operational challenges byautomating workflowsand ensuring thehealth 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 providingautomated toolslike 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 issuesor reduce the dependency on the operations team for manual issue resolution.

NEW QUESTION # 35
Which two actions can a systems engineer take to discover how Palo Alto Networks can bring value to a customer's business when they show interest in adopting Zero Trust? (Choose two.)
- A. Ask the customer about their approach to Zero Trust, explaining that it is a strategy more than it is something they purchase.
- B. Explain how Palo Alto Networks can place virtual NGFWs across the customer's network to ensure assets and traffic are seen and controlled.
- C. Use the Zero Trust Roadshow package to demonstrate to the customer how robust Palo Alto Networks capabilities are in meeting Zero Trust.
- D. Ask the customer about their internal business flows, such as how their users interact with applications and data across the infrastructure.
Answer: A,D
Explanation:
To help a customer understand how Palo Alto Networks can bring value when adopting a Zero Trust architecture, the systems engineer must focus on understanding the customer's specific needs and explaining how the Zero Trust strategy aligns with their business goals. Here's the detailed analysis of each option:
* Option A: Ask the customer about their internal business flows, such as how their users interact with applications and data across the infrastructure
* Understanding the customer's internal workflows and how their users interact with applications and data is a critical first step in Zero Trust. This information allows the systems engineer to identify potential security gaps and suggest tailored solutions.
* This is correct.
* Option B: Explain how Palo Alto Networks can place virtual NGFWs across the customer's network to ensure assets and traffic are seen and controlled
* While placing NGFWs across the customer's network may be part of the implementation, this approach focuses on the product rather than the customer's strategy. Zero Trust is more about policies and architecture than specific product placement.
* This is incorrect.
* Option C: Use the Zero Trust Roadshow package to demonstrate to the customer how robust Palo Alto Networks capabilities are in meeting Zero Trust
* While demonstrating capabilities is valuable during the later stages of engagement, the initial focus should be on understanding the customer's business requirements rather than showcasing products.
* This is incorrect.
* Option D: Ask the customer about their approach to Zero Trust, explaining that it is a strategy more than it is something they purchase
* Zero Trust is not a product but a strategy that requires a shift in mindset. By discussing their approach, the systems engineer can identify whether the customer understands Zero Trust principles and guide them accordingly.
* This is correct.

* Zero Trust Architecture Principles inNIST 800-207
NEW QUESTION # 36
Which two actions should a systems engineer take when a customer is concerned about how to remain aligned to Zero Trust principles as they adopt additional security features over time? (Choose two)
- A. Use the Best Practice Assessment (BPA) tool to measure progress toward Zero Trust principles.
- B. Use the Policy Optimizer tool to understand security rules allowing users to bypass decryption.
- C. Turn on all licensed Cloud-Delivered Security Services (CDSS) subscriptions in blocking mode for all policies.
- D. Apply decryption where possible to inspect and log all new and existing traffic flows.
Answer: A,D
Explanation:
When adopting additional security features over time, remaining aligned with Zero Trust principles requires a focus on constant visibility, control, and adherence to best practices. The following actions are the most relevant:
* Why "Apply decryption where possible to inspect and log all new and existing traffic flows" (Correct Answer B)?Zero Trust principles emphasize visibility into all traffic, whether encrypted or unencrypted. Without decryption, encrypted traffic becomes a blind spot, which attackers can exploit.
By applying decryption wherever feasible, organizations ensure they can inspect, log, and enforce policies on encrypted traffic, thus adhering to Zero Trust principles.
* Why "Use the Best Practice Assessment (BPA) tool to measure progress toward Zero Trust principles" (Correct Answer C)?The BPA tool provides detailed insights into the customer's security configuration, helping measure alignment with Palo Alto Networks' Zero Trust best practices. It identifies gaps in security posture and recommends actionable steps to strengthen adherence to Zero Trust principles over time.
* Why not "Turn on all licensed Cloud-Delivered Security Services (CDSS) subscriptions in blocking mode for all policies" (Option A)?While enabling CDSS subscriptions (like Threat Prevention, URL Filtering, Advanced Threat Prevention) in blocking mode can enhance security, it is not an action specifically tied to maintaining alignment with Zero Trust principles. A more holistic approach, such as decryption and BPA analysis, is critical to achieving Zero Trust.
* Why not "Use the Policy Optimizer tool to understand security rules allowing users to bypass decryption" (Option D)?Policy Optimizer is used to optimize existing security rules by identifying unused or overly permissive policies. While useful, it does not directly address alignment with Zero Trust principles or help enforce decryption.
Reference: Palo Alto Networks' Zero Trust documentation and Best Practice Assessment (BPA) confirm the importance of decryption and best practices in aligning with Zero Trust principles.
NEW QUESTION # 37
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.

* Palo Alto Networks5G Securityis 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 arenot compromisedby 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 NetworksIoT Securityprovides:
* 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):
* WhileCloud NGFWis critical for protecting cloud-based applications, the specific concern here is protecting control signals and IoT devicesrather than external access into the cloud service.
* The private mobile network and IoT device protection requirements make5G SecurityandIoT Securitymore 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 networksandIoT devices.
* While these services can supplement the design, they are not theprimary focusin this use case.

- A. PAN-CN-MGMT-CONFIGMAP
- B. PAN-CNI-MULTUS
- C. PAN-CN-MGMT
- D. PAN-CN-NGFW-CONFIG
Answer: A,D
Explanation:
CN-Series firewalls are Palo Alto Networks' containerized NGFWs designed for protecting Kubernetes environments. These firewalls provide threat prevention, traffic inspection, and compliance enforcement within containerized workloads. Deploying CN-Series in a Kubernetescluster requires specific configuration files to set up the management plane and NGFW functionalities.
* Option A (Correct):PAN-CN-NGFW-CONFIGis required to define the configurations for the NGFW itself. This file contains firewall policies, application configurations, and security profiles needed to secure the Kubernetes environment.
* Option B (Correct):PAN-CN-MGMT-CONFIGMAPis a ConfigMap file that contains the configuration for the management plane of the CN-Series firewall. It helps set up the connection between the management interface and the NGFW deployed within the Kubernetes cluster.
* Option C:This option does not represent a valid or required file for deploying CN-Series firewalls. The management configurations are handled via the ConfigMap.
* Option D:PAN-CNI-MULTUSrefers to the Multus CNI plugin for Kubernetes, which is used for enabling multiple network interfaces in pods. While relevant for Kubernetes networking, it is not specific to deploying CN-Series firewalls.

NEW QUESTION # 39
A company plans to deploy identity for improved visibility and identity-based controls for least privilege access to applications and data. The company does not have an on-premises Active Directory (AD) deployment, and devices are connected and managed by using a combination of Entra ID and Jamf.
Which two supported sources for identity are appropriate for this environment? (Choose two.)
- A. Cloud Identity Engine synchronized with Entra ID
- B. GlobalProtect with an internal gateway deployment
- C. Captive portal
- D. User-ID agents configured for WMI client probing
Answer: A,B
Explanation:
In this scenario, the company does not use on-premises Active Directory and manages devices with Entra ID and Jamf, which implies a cloud-native and modern management setup. Below is the evaluation of each option:
* Option A: Captive portal
* Captive portal is typically used in environments where identity mapping is needed for unmanaged devices or guest users. It provides a mechanism for users to authenticate themselves through a web interface.
* However, in this case, the company is managing devices using Entra ID and Jamf, which means identity information can already be centralized through other means. Captive portal is not an ideal solution here.
* This option is not appropriate.
* Option B: User-ID agents configured for WMI client probing
* WMI (Windows Management Instrumentation) client probing is a mechanism used to map IP addresses to usernames in a Windows environment. This approach is specific to on-premises Active Directory deployments and requires direct communication with Windows endpoints.
* Since the company does not have an on-premises AD and is using Entra ID and Jamf, this method is not applicable.
* This option is not appropriate.
* Option C: GlobalProtect with an internal gateway deployment
* GlobalProtect is Palo Alto Networks' VPN solution, which allows for secure remote access. It also supports identity-based mapping when deployed with internal gateways.
* In this case, GlobalProtect with an internal gateway can serve as a mechanism to provide user and device visibility based on the managed devices connecting through the gateway.
* This option is appropriate.
* Option D: Cloud Identity Engine synchronized with Entra ID
* The Cloud Identity Engine provides a cloud-based approach to synchronize identity information from identity providers like Entra ID (formerly Azure AD).
* In a cloud-native environment with Entra ID and Jamf, the Cloud Identity Engine is a natural fit as it integrates seamlessly to provide identity visibility for applicationsand data.
* This option is appropriate.

NEW QUESTION # 40
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. DNS Security
- B. App-ID and Data Loss Prevention
- C. Threat Prevention
- D. Advanced Threat Prevention and Advanced URL Filtering
Answer: A
Explanation:
Option C: It can be addressed with BGP confederations
Description: BGP confederations divide a single AS into sub-ASes (each with a private Confederation Member AS number), reducing the iBGP full-mesh requirement while maintaining a unified external AS.
Analysis:
How It Works:
Single AS (e.g., AS 65000) is split into sub-ASes (e.g., 65001, 65002).
Within each sub-AS, iBGP full mesh or route reflectors are used.
Between sub-ASes, eBGP-like peering (confederation EBGP) connects them, but externally, it appears as one AS.
Segregation:
Each sub-AS can represent a unique BGP environment (e.g., department, site) with its own routing policies.
Firewalls within a sub-AS peer via iBGP; across sub-ASes, they use confederation EBGP.
PAN-OS Support:
Configurable under "Network > Virtual Routers > BGP > Confederation" with a Confederation Member AS number.
Ideal for large internal networks needing segmentation without multiple public AS numbers.
Benefits:
Simplifies internal BGP management.
Aligns with the customer's need for unique internal BGP environments.
Verification:
"BGP confederations reduce full-mesh burden by dividing an AS into sub-ASes" (docs.paloaltonetworks.com
/pan-os/10-2/pan-os-networking-admin/bgp/bgp-confederations).
"Supports unique internal routing domains" (knowledgebase.paloaltonetworks.com).
Conclusion: Directly addresses the requirement with a supported, practical solution. Applicable.
Option D: It cannot be addressed because BGP must be fully meshed internally to work Analysis:
iBGP Full Mesh: Traditional iBGP requires all routers in an AS to peer with each other, scaling poorly (n(n-
1)/2 connections).
Mitigation: PAN-OS supports alternatives:
Route Reflectors: Centralize iBGP peering.
Confederations: Divide the AS into sub-ASes (see Option C).
This statement ignores these features, falsely claiming BGP's limitation prevents segregation.
Verification:
"Confederations and route reflectors eliminate full-mesh needs" (docs.paloaltonetworks.com/pan-os/10-2/pan- os-networking-admin/bgp/bgp-confederations).
Conclusion: Incorrect-PAN-OS overcomes full-mesh constraints. Not Applicable.
Step 3: Recommendation Justification
Why Option C?
Alignment: Confederations allow the internal network to be segregated into unique BGP environments (sub- ASes) while maintaining a single external AS, perfectly matching the customer's need.
Scalability: Reduces iBGP full-mesh complexity, ideal for large or segmented internal networks.
PAN-OS Support: Explicitly implemented in BGP configuration, validated by documentation.
Why Not Others?
A: False-PAN-OS supports BGP and segregation.
B: eBGP is for external ASes, not internal segregation; less practical than confederations.
D: Misrepresents BGP capabilities; full mesh isn't required with confederations or route reflectors.
Step 4: Verified References
BGP Confederations: "Divide an AS into sub-ASes for internal segmentation" (docs.paloaltonetworks.com
/pan-os/10-2/pan-os-networking-admin/bgp/bgp-confederations).
PAN-OS BGP: "Supports eBGP, iBGP, and confederations for routing flexibility" (paloaltonetworks.com, PAN-OS Networking Guide).
Use Case: "Confederations suit large internal networks" (knowledgebase.paloaltonetworks.com).
NEW QUESTION # 41
Which two statements clarify the functionality and purchase options for Palo Alto Networks AIOps for NGFW? (Choose two.)
- A. It uses telemetry data to forecast, preempt, or identify issues, and it uses machine learning (ML) to adjust and enhance the process.
- B. It is offered in two license tiers: a free version and a premium version.
- C. 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.
- D. It is offered in two license tiers: a commercial edition and an enterprise edition.
Answer: A,B
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.

* 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.
NEW QUESTION # 42
Which two statements correctly describe best practices for sizing a firewall deployment with decryption enabled? (Choose two.)
- A. 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.
- B. SSL decryption traffic amounts vary from network to network.
- C. Large average transaction sizes consume more processing power to decrypt.
- D. 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.
Answer: A,B
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 "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" (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 directly relevant to sizing considerations for firewall deployments with decryption enabled.
Reference: Palo Alto Networks SSL Decryption Best Practices outlines considerations for sizing deployments with decryption, including variability in SSL traffic and the impact of encryption algorithms like ECDHE.

Which two tools should a systems engineer use to showcase the benefit of an evaluation that a customer has just concluded?
- A. Best Practice Assessment (BPA)
- B. Firewall Sizing Guide
- C. Golden Images
- D. Security Lifecycle Review (SLR)
Answer: A,D
Explanation:
After a customer has concluded an evaluation of Palo Alto Networks solutions, it is critical to provide a detailed analysis of the results and benefits gained during the evaluation. The following two tools are most appropriate:
* Why "Best Practice Assessment (BPA)" (Correct Answer A)?The BPA evaluates the customer's firewall configuration against Palo Alto Networks' recommended best practices. It highlights areas where the configuration could be improved to strengthen security posture. This is an excellent tool to showcase how adopting Palo Alto Networks' best practices aligns with industry standards and improves security performance.
* Why "Security Lifecycle Review (SLR)" (Correct Answer B)?The SLR provides insights into the customer's security environment based on data collected during the evaluation. It identifies vulnerabilities, risks, and malicious activities observed in the network and demonstrates how Palo Alto Networks' solutions can address these issues. SLR reports use clear visuals and metrics, making it easier to showcase the benefits of the evaluation.
* Why not "Firewall Sizing Guide" (Option C)?The Firewall Sizing Guide is a pre-sales tool used to recommend the appropriate firewall model based on the customer's network size, performance requirements, and other criteria. It is not relevant for showcasing the benefits of an evaluation.
* Why not "Golden Images" (Option D)?Golden Images refer to pre-configured templates for deploying firewalls in specific use cases. While useful for operational efficiency, they are not tools for demonstrating the outcomes or benefits of a customer evaluation.
Reference: Palo Alto Networks documentation for Best Practice Assessment (BPA) and Security Lifecycle Review (SLR) confirms their role in showcasing evaluation benefits.
NEW QUESTION # 44
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 an include group list.
- B. Configure a group mapping profile with custom filters for LDAP attributes that are mapped to the user roles.
- C. Configure NGFWs to synchronize with the AD after deploying the Cloud Identity Engine (CIE) and agents.
- D. Configure a group mapping profile, without a filter, to synchronize all groups.
Answer: A
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 listto 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 aninclude group listensures 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.
