問題 #57
Which three known variables can assist with sizing an NGFW appliance? (Choose three.)
- A. Packet replication
- B. App-ID firewall throughput
- C. Max sessions
- D. Telemetry enabled
- E. Connections per second
答案：B,C,E
解題說明：
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
問題 #58
Which two statements correctly describe best practices for sizing a firewall deployment with decryption enabled? (Choose two.)
- A. Large average transaction sizes consume more processing power to decrypt.
- 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. 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.
答案：B,C
解題說明：
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 directlyrelevant to sizing considerations for firewall deployments with decryption enabled.
問題 #59
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. 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. 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.
答案：A,B
解題說明：
* 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.

問題 #60
A customer asks a systems engineer (SE) how Palo Alto Networks can claim it does not lose throughput performance as more Cloud-Delivered Security Services (CDSS) subscriptions are enabled on the firewall.
Which two concepts should the SE explain to address the customer's concern? (Choose two.)
- A. Advanced Routing Engine
- B. Single Pass Architecture
- C. Parallel Processing
- D. Management Data Plane Separation
答案：B,C
解題說明：
The customer's question focuses on how Palo Alto Networks Strata Hardware Firewalls maintain throughput performance as more Cloud-Delivered Security Services (CDSS) subscriptions-such as Threat Prevention, URL Filtering, WildFire, DNS Security, and others-are enabled. Unlike traditional firewalls where enabling additional security features often degrades performance, Palo Alto Networks leverages its unique architecture to minimize this impact. The systems engineer (SE) should explain two key concepts-Parallel Processing andSingle Pass Architecture-which are foundational to the firewall's ability to sustain throughput. Below is a detailed explanation, verified against Palo Alto Networks documentation.
Step 1: Understanding Cloud-Delivered Security Services (CDSS) and Performance Concerns CDSS subscriptions enhance the Strata Hardware Firewall's capabilities by integrating cloud-based threat intelligence and advanced security features into PAN-OS. Examples include:
* Threat Prevention: Blocks exploits, malware, and command-and-control traffic.
* WildFire: Analyzes unknown files in the cloud for malware detection.
* URL Filtering: Categorizes and controls web traffic.
Traditionally, enabling such services on other firewalls increases processing overhead, as each feature requires separate packet scans or additional hardware resources, leading to latency and throughput loss. Palo Alto Networks claims consistent performance due to its innovative design, rooted in theSingle Pass Parallel Processing (SP3)architecture.
問題 #61
In which two locations can a Best Practice Assessment (BPA) report be generated for review by a customer?
(Choose two.)
- A. Strata Cloud Manager (SCM)
- B. PANW Partner Portal
- C. Customer Support Portal
- D. AIOps
答案：B,C
解題說明：
The Best Practice Assessment (BPA) report evaluates firewall and Panorama configurations against Palo Alto Networks' best practice recommendations. It provides actionable insights to improve the security posture of the deployment. BPA reports can be generated from the following locations:
* Why "PANW Partner Portal" (Correct Answer A)?Partners with access to the Palo Alto Networks Partner Portal can generate BPA reports for customers as part of their service offerings. This allows partners to assess and demonstrate compliance with best practices.
* Why "Customer Support Portal" (Correct Answer B)?Customers can log in to the Palo Alto Networks Customer Support Portal to generate their own BPA reports. This enables organizations to self-assess and improve their firewall configurations.
* Why not "AIOps" (Option C)?While AIOps provides operational insights and best practice recommendations, it does not generate full BPA reports. BPA and AIOps are distinct tools within the Palo Alto Networks ecosystem.
* Why not "Strata Cloud Manager (SCM)" (Option D)?Strata Cloud Manager is designed for managing multiple Palo Alto Networks cloud-delivered services and NGFWs but does not currently support generating BPA reports. BPA is limited to the Partner Portal and Customer Support Portal.
