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

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 theWeb InterfaceorCLIon the firewall.

Navigate toDevice > 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

commit

Verify the configuration using the show command or by testing API calls to ensure the key expires after the set duration.

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.

WildFire Analysis Reports

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.

Discovering Applications on the Network (Answer A):

Policy Optimizeranalyzes traffic logs to identifyapplications running on the networkthat are currently being allowed by port-based or overly permissive policies.

It providesvisibilityinto these applications, enabling administrators to transition to more secure,application-based policies over time.

Converting Broad Rules into Narrow Rules (Answer B):

Policy Optimizer helps refine policies byconverting broad application filters(e.g., rules that allow all web applications) intonarrower rules based on specific application groups.

This reduces the risk of overly permissive access while maintaining granular control.

Migrating from Port-Based Rules to Application-Based Rules (Answer C):

One of the primary use cases for Policy Optimizer is enabling organizations tomigrate from legacy port-based rules to application-based rules, which are more secure and aligned with Zero Trust principles.

Policy Optimizer identifies traffic patterns and automatically recommends the necessary application-based policies.

Why Not D:

5-tuple attributes (source IP, destination IP, source port, destination port, protocol)are used in traditional firewalls. Simplifying these attributes to 4-tuple (e.g., removing the protocol) is not a use case for Policy Optimizer, as Palo Alto Networks NGFWs focus onapplication-based policies, not just 5-tuple matching.

Why Not E:

Automating tagging of rules based on historical log data is not a specific feature of Policy Optimizer. While Policy Optimizer analyzes log data to recommend policy changes, tagging is not its primary use case.
