Paloalto Networks Updated PSE-Strata-Pro-24 Exam Questions and Answers by sultan

Security Lifecycle Review (SLR) (Answer A):

TheSecurity Lifecycle Review (SLR)is a detailed report generated by Palo Alto Networks firewalls that providesvisibility into application usage, threats, and policy alignmentwith industry standards.

During the POV, running an SLR near the end of the timeline allows the customer to see:

How well their current security policies align withCritical Security Controls (CSC)or other industry standards.

Insights into application usage and threats discovered during the POV.

This providesactionable recommendationsfor optimizing policies and ensuring the purchased functionality is being effectively utilized.

Why Not B:

While creating custom dashboards and reports at the beginning might provide useful insights, the question focuses onverifying progress toward meeting CSC standards. This is specifically addressed by the SLR, which is designed to measure and report on such criteria.

Why Not C:

Pulling information fromSCM dashboards like Best Practices and Feature Adoptioncan help assess firewall functionality but may not provide acomprehensive review of compliance or CSC alignment, as the SLR does.

Why Not D:

WhilePANhandler golden imagescan help configure features in alignment with specific subscriptions or compliance goals, they are primarily used to deploy predefined templates, not to assess security policy effectiveness or compliance with CSC standards.

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 isAdvanced Threat Prevention (ATP)combined withPAN-OS 11.x.

Why "Advanced Threat Prevention and PAN-OS 11.x" (Correct Answer B)?Advanced Threat Prevention (ATP) enhances traditional threat prevention by usinginline deep learning modelsto detect and block advanced zero-day threats, includingSQL 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 onThreat 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.

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.

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 moreadvanced 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 thecapacity planning issuesor reduce the dependency on the operations team for manual issue resolution.
