Paloalto Networks PSE-Strata-Pro-24 Dumps Questions Answers

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 is not 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.

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 a group mapping profile with an include group list to 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 an include group list ensures 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.

The appropriate CDSS subscription to inspect and mitigate suspicious DNS traffic is Advanced DNS Security. Here’s why:

Advanced DNS Security protects against DNS-based threats, including domain generation algorithms (DGA), DNS tunneling (often used for data exfiltration), and malicious domains used in attacks. It leverages machine learning to detect and block DNS traffic associated with command-and-control servers or other malicious activities. In this case, unusually high DNS traffic to an unfamiliar IP address is likely indicative of a DNS-based attack or malware activity, making this the most suitable service.

Option A: Advanced Threat Prevention (ATP) focuses on identifying and blocking sophisticated threats in network traffic, such as exploits and evasive malware. While it complements DNS Security, it does not specialize in analyzing DNS-specific traffic patterns.

Option B: Advanced WildFire focuses on detecting and preventing file-based threats, such as malware delivered via email attachments or web downloads. It does not provide specific protection for DNS-related anomalies.

Option C: Advanced URL Filtering is designed to prevent access to malicious or inappropriate websites based on their URLs. While DNS may be indirectly involved in resolving malicious websites, this service does not directly inspect DNS traffic patterns for threats.

Option D (Correct): Advanced DNS Security specifically addresses DNS-based threats. By enabling this service, the customer can detect and block DNS queries to malicious domains and investigate anomalous DNS behavior like the high traffic observed in this scenario.

How to Enable Advanced DNS Security:

Ensure the firewall has a valid Advanced DNS Security license.

Navigate to Objects > Security Profiles > Anti-Spyware.

Enable DNS Security under the "DNS Signatures" section.

Apply the Anti-Spyware profile to the relevant Security Policy to enforce DNS Security.
