Palo Alto Networks XDR Analyst Sample Questions (Q34-Q39):

NEW QUESTION # 34
To stop a network-based attack, any interference with a portion of the attack pattern is enough to prevent it from succeeding. Which statement is correct regarding the Cortex XDR Analytics module?

A. It does not interfere with any portion of the pattern on the endpoint.
B. It does not need to interfere with the any portion of the pattern to prevent the attack.
C. It interferes with the pattern as soon as it is observed on the endpoint.
D. It interferes with the pattern as soon as it is observed by the firewall.

Answer: C

Explanation:
The correct statement regarding the Cortex XDR Analytics module is D, it interferes with the pattern as soon as it is observed on the endpoint. The Cortex XDR Analytics module is a feature of Cortex XDR that uses machine learning and behavioral analytics to detect and prevent network-based attacks on endpoints. The Cortex XDR Analytics module analyzes the network traffic and activity on the endpoint, and compares it with the attack patterns defined by Palo Alto Networks threat research team. The Cortex XDR Analytics module interferes with the attack pattern as soon as it is observed on the endpoint, by blocking the malicious network connection, process, or file. This way, the Cortex XDR Analytics module can stop the attack before it causes any damage or compromise.
The other statements are incorrect for the following reasons:
A is incorrect because the Cortex XDR Analytics module does interfere with the attack pattern on the endpoint, by blocking the malicious network connection, process, or file. The Cortex XDR Analytics module does not rely on the firewall or any other network device to stop the attack, but rather uses the Cortex XDR agent installed on the endpoint to perform the interference.
B is incorrect because the Cortex XDR Analytics module does not interfere with the attack pattern as soon as it is observed by the firewall. The Cortex XDR Analytics module does not depend on the firewall or any other network device to detect or prevent the attack, but rather uses the Cortex XDR agent installed on the endpoint to perform the analysis and interference. The firewall may not be able to observe or block the attack pattern if it is encrypted, obfuscated, or bypassed by the attacker.
C is incorrect because the Cortex XDR Analytics module does need to interfere with the attack pattern to prevent the attack. The Cortex XDR Analytics module does not only detect the attack pattern, but also prevents it from succeeding by blocking the malicious network connection, process, or file. The Cortex XDR Analytics module does not rely on any other response mechanism or human intervention to stop the attack, but rather uses the Cortex XDR agent installed on the endpoint to perform the interference.

NEW QUESTION # 35
What is the outcome of creating and implementing an alert exclusion?

A. The Cortex XDR agent will not create an alert for this event in the future.
B. The Cortex XDR agent will allow the process that was blocked to run on the endpoint.
C. The Cortex XDR console will delete those alerts and block ingestion of them in the future.
D. The Cortex XDR console will hide those alerts.

Answer: D

Explanation:
The outcome of creating and implementing an alert exclusion is that the Cortex XDR console will hide those alerts that match the exclusion criteria. An alert exclusion is a policy that allows you to filter out alerts that are not relevant, false positives, or low priority, and focus on the alerts that require your attention. When you create an alert exclusion, you can specify the criteria that define which alerts you want to exclude, such as alert name, severity, source, or endpoint. After you create an alert exclusion, Cortex XDR will hide any future alerts that match the criteria, and exclude them from incidents and search query results. However, the alert exclusion does not affect the behavior of the Cortex XDR agent or the security policy on the endpoint. The Cortex XDR agent will still create an alert for the event and apply the appropriate action, such as blocking or quarantining, according to the security policy. The alert exclusion only affects the visibility of the alert on the Cortex XDR console, not the actual protection of the endpoint. Therefore, the correct answer is B, the Cortex XDR console will hide those alerts12 Reference:

NEW QUESTION # 36
What is the Wildfire analysis file size limit for Windows PE files?

A. 1GB
B. 100MB
C. 500MB
D. No Limit

Answer: B

Explanation:
The Wildfire analysis file size limit for Windows PE files is 100MB. Windows PE files are executable files that run on the Windows operating system, such as .exe, .dll, .sys, or .scr files. Wildfire is a cloud-based service that analyzes files and URLs for malicious behavior and generates signatures and protections for them. Wildfire can analyze various file types, such as PE, APK, PDF, MS Office, and others, but each file type has a different file size limit. The file size limit determines the maximum size of the file that can be uploaded or forwarded to Wildfire for analysis. If the file size exceeds the limit, Wildfire will not analyze the file and will return an error message.
According to the Wildfire documentation1, the file size limit for Windows PE files is 100MB. This means that any PE file that is larger than 100MB will not be analyzed by Wildfire. However, the firewall can still apply other security features, such as antivirus, anti-spyware, vulnerability protection, and file blocking, to the PE file based on the security policy settings. The firewall can also perform local analysis on the PE file using the Cortex XDR agent, which uses machine learning models to assess the file and assign it a verdict2.

Local Analysis: This document explains how the Cortex XDR agent performs local analysis on files that cannot be sent to Wildfire for analysis.

NEW QUESTION # 37
Which of the following paths will successfully activate Remediation Suggestions?

A. Alerts Table > Right-click on a process node > Remediation Suggestions
B. Incident View > Actions > Remediation Suggestions
C. Alerts Table > Right-click on an alert > Remediation Suggestions
D. Causality View > Actions > Remediation Suggestions

Answer: D

Explanation:
Remediation Suggestions is a feature of Cortex XDR that provides you with recommended actions to remediate the root cause and impact of an incident. Remediation Suggestions are based on the analysis of the causality chain, the behavior of the malicious files or processes, and the best practices for incident response. Remediation Suggestions can help you to quickly and effectively contain and resolve an incident, as well as prevent future recurrence.
To activate Remediation Suggestions, you need to follow these steps:
In the Cortex XDR management console, go to Incidents and select an incident that you want to remediate.
Click Causality View to see the graphical representation of the causality chain of the incident.
Click Actions and select Remediation Suggestions. This will open a new window that shows the suggested actions for each node in the causality chain.
Review the suggested actions and select the ones that you want to apply. You can also edit or delete the suggested actions, or add your own custom actions.
Click Apply to execute the selected actions on the affected endpoints. You can also schedule the actions to run at a later time or date.
Reference:

Causality View: This document describes how to use Causality View to investigate the causality chain of an incident.

NEW QUESTION # 38
When is the wss (WebSocket Secure) protocol used?

A. when the Cortex XDR agent connects to WildFire to upload files for analysis
B. when the Cortex XDR agent downloads new security content
C. when the Cortex XDR agent uploads alert data
D. when the Cortex XDR agent establishes a bidirectional communication channel

Answer: D

Explanation:
The WSS (WebSocket Secure) protocol is an extension of the WebSocket protocol that provides a secure communication channel over the internet. It is used to establish a persistent, full-duplex communication channel between a client (in this case, the Cortex XDR agent) and a server (such as the Cortex XDR management console or other components). The Cortex XDR agent uses the WSS protocol to establish a secure and real-time bidirectional communication channel with the Cortex XDR management console or other components in the Palo Alto Networks security ecosystem. This communication channel allows the agent to send data, such as security events, alerts, and other relevant information, to the management console, and receive commands, policy updates, and responses in return. By using the WSS protocol, the Cortex XDR agent can maintain a persistent connection with the management console, which enables timely communication of security-related information and allows for efficient incident response and remediation actions. It's important to note that the other options mentioned in the question also involve communication between the Cortex XDR agent and various components, but they do not specifically mention the use of the WSS protocol. For example:
A . The Cortex XDR agent downloading new security content typically utilizes protocols like HTTP or HTTPS.
B . When the Cortex XDR agent uploads alert data, it may use protocols like HTTP or HTTPS to transmit the data securely.
C . When the Cortex XDR agent connects to WildFire to upload files for analysis, it typically uses protocols like HTTP or HTTPS. Therefore, the correct answer is D, when the Cortex XDR agent establishes a bidirectional communication channel. Reference:
