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?
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.
What does Policy Optimizer allow a systems engineer to do for an NGFW?
Policy Optimizer is a feature designed to help administrators improve the efficiency and effectiveness of security policies on Palo Alto Networks Next-Generation Firewalls (NGFWs). It focuses on identifying unused or overly permissive policies to streamline and optimize the configuration.
Why 'Identify Security policy rules with unused applications' (Correct Answer C)?
Policy Optimizer provides visibility into existing security policies and identifies rules that have unused or outdated applications. For example:
It can detect if a rule allows applications that are no longer in use.
It can identify rules with excessive permissions, enabling administrators to refine them for better security and performance.
By addressing these issues, Policy Optimizer helps reduce the attack surface and improves the overall manageability of the firewall.
Why not 'Recommend best practices on new policy creation' (Option A)?
Policy Optimizer focuses on optimizing existing policies, not creating new ones. While best practices can be applied during policy refinement, recommending new policy creation is not its purpose.
Why not 'Show unused licenses for Cloud-Delivered Security Services (CDSS) subscriptions and firewalls' (Option B)?
Policy Optimizer is not related to license management or tracking. Identifying unused licenses is outside the scope of its functionality.
Why not 'Act as a migration tool to import policies from third-party vendors' (Option D)?
Policy Optimizer does not function as a migration tool. While Palo Alto Networks offers tools for third-party firewall migration, this is separate from the Policy Optimizer feature.
Which two statements correctly describe best practices for sizing a firewall deployment with decryption enabled? (Choose two.)
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.
Which three tools can a prospective customer use to evaluate Palo Alto Networks products to assess where they will fit in the existing architecture? (Choose three)
When evaluating Palo Alto Networks products, prospective customers need tools that can help them assess compatibility, performance, and value within their existing architecture. The following tools are the most relevant:
Why 'Proof of Concept (POC)' (Correct Answer A)?
A Proof of Concept is a hands-on evaluation that allows the customer to deploy and test Palo Alto Networks products directly within their environment. This enables them to assess real-world performance, compatibility, and operational impact.
Why 'Security Lifecycle Review (SLR)' (Correct Answer C)?
An SLR provides a detailed report of a customer's network security posture based on data collected during a short evaluation period. It highlights risks, vulnerabilities, and active threats in the customer's network, demonstrating how Palo Alto Networks solutions can address those risks. SLR is a powerful tool for justifying the value of a product in the customer's architecture.
Why 'Ultimate Test Drive' (Correct Answer D)?
The Ultimate Test Drive is a guided hands-on workshop provided by Palo Alto Networks that allows prospective customers to explore product features and capabilities in a controlled environment. It is ideal for customers who want to evaluate products without deploying them in their production network.
Why not 'Policy Optimizer' (Option B)?
Policy Optimizer is used after a product has been deployed to refine security policies by identifying unused or overly permissive rules. It is not designed for pre-deployment evaluations.
Why not 'Expedition' (Option E)?
Expedition is a migration tool that assists with the conversion of configurations from third-party firewalls or existing Palo Alto Networks firewalls. It is not a tool for evaluating the suitability of products in the customer's architecture.
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?
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.
