NEW QUESTION # 17
What happens when the XDR Collector is uninstalled from an endpoint by using the Cortex XDR console?
Answer: C
Explanation:
TheXDR Collectoris a lightweight agent in Cortex XDR used to collect logs and events from endpoints or servers. When uninstalled via the Cortex XDR console, the uninstallation process is initiated remotely, but the actual removal occurs during the endpoint's next communication with the Cortex XDR tenant, known as the heartbeat. The heartbeat interval is typically every few minutes, ensuring timely uninstallation. After uninstallation, the machine's status in the console updates, and associated configuration data is retained for a specific period to support potential reinstallation or auditing.
* Correct Answer Analysis (C):When the XDR Collector is uninstalled using the Cortex XDR console, it is uninstalled during the next heartbeat communication, themachine status changes to Uninstalled, and theconfiguration data is retained for 90 days. This retention period allows administrators to review historical data or reinstall the collector if needed, after which the data is permanently deleted.
* Why not the other options?
* A. The files are removed immediately, and the machine is deleted from the system without any retention period: Uninstallation is not immediate; it occurs at the next heartbeat.
Additionally, Cortex XDR retains configuration data for a period, not deleting it immediately.
* B. The machine status remains active until manually removed, and the configuration data is retained for up to seven days: The machine status updates to Uninstalled automatically, not requiring manual removal, and the retention period is 90 days, not seven days.
* D. The associated configuration data is removed from the Action Center immediately after uninstallation: Configuration data is retained for 90 days, not removed immediately, and the Action Center is not the primary location for this data.
Exact Extract or Reference:
TheCortex XDR Documentation Portalexplains XDR Collector uninstallation: "Whenuninstalled via the console, the XDR Collector is removed at the next heartbeat, the machine status changes to Uninstalled, and configuration data is retained for 90 days" (paraphrased from the XDR Collector Management section). The EDU-260: Cortex XDR Prevention and Deploymentcourse covers collector management, stating that
"uninstallation occurs at the next heartbeat, with a 90-day retention period for configuration data" (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetincludes
"post-deployment management and configuration" as a key exam topic, encompassing XDR Collector uninstallation.

NEW QUESTION # 18
When using Kerberos as the authentication method for Pathfinder, which two settings must be validated on the DNS server? (Choose two.)
Answer: A,D
Explanation:
Pathfinderin Cortex XDR is a tool for discovering unmanaged endpoints in a network, often using authentication methods likeKerberosto access systems securely. Kerberos authentication relies heavily on DNS for resolving hostnames and ensuring proper communication between clients, servers, and the Kerberos Key Distribution Center (KDC). Specific DNS settings must be validated to ensure Kerberos authentication works correctly for Pathfinder.
* Correct Answer Analysis (B, C):
* B. Reverse DNS zone: Areverse DNS zoneis required to map IP addresses to hostnames (PTR records), which Kerberos uses to verify the identity of servers and clients. Without a properly configured reverse DNS zone, Kerberos authentication may fail due to hostname resolution issues.
* C. Reverse DNS records:Reverse DNS records(PTR records) within the reverse DNS zone must be correctly configured for all relevant hosts. These records ensure that IP addresses resolve to the correct hostnames, which is critical for Kerberos to authenticate Pathfinder's access to endpoints.
* Why not the other options?
* A. DNS forwarders: DNS forwarders are used to route DNS queries to external servers when a local DNS server cannot resolve them. While useful for general DNS resolution, they are not specifically required for Kerberos authentication or Pathfinder.
* D. AD DS-integrated zones: Active Directory Domain Services (AD DS)-integrated zones enhance DNS management in AD environments, but they are not strictly required for Kerberos authentication. Kerberos relies on proper forward and reverse DNS resolution, not AD-specific DNS configurations.
Exact Extract or Reference:
TheCortex XDR Documentation Portalexplains Pathfinder configuration: "For Kerberos authentication, ensure that the DNS server has a properly configured reverse DNS zone and reverse DNS records to support hostname resolution" (paraphrased from the Pathfinder Configuration section). TheEDU-260: Cortex XDR Prevention and Deploymentcourse covers Pathfinder setup, stating that "Kerberos requires valid reverse DNS zones and PTR records for authentication" (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetincludes "planning and installation" as a key exam topic, encompassing Pathfinder authentication settings.

NEW QUESTION # 19
Multiple remote desktop users complain of in-house applications no longer working. The team uses macOS with Cortex XDR agents version 8.7.0, and the applications were previously allowed by disable prevention rules attached to the Exceptions Profile "Engineer-Mac." Based on the images below, what is a reason for this behavior?
Answer: D
Explanation:
The scenario involves macOS users with Cortex XDR agents (version 8.7.0) who can no longer run in-house applications that were previously allowed via disable prevention rules in the"Engineer-Mac" Exceptions Profile. This profile is applied to an endpoint group (e.g., "Mac-Engineers"). Theissue likely stems from a change in the endpoint group's configuration or the endpoints' attributes, affecting policy application.
* Correct Answer Analysis (A):The reason for the behavior is that theendpoint IP address changed from 192.168.0.0 range to 192.168.100.0 range. In Cortex XDR, endpoint groups can be defined using dynamic criteria, such as IP address ranges, to apply specific policies like the "Engineer-Mac" Exceptions Profile. If the group "Mac-Engineers" was defined to include endpoints in the 192.168.0.0 range, and the remote desktop users' IP addresses changed to the 192.168.100.0 range (e.g., due to a network change or VPN reconfiguration), these endpoints would no longer belong to the "Mac- Engineers" group. As a result, the "Engineer-Mac" Exceptions Profile, which allowed the in-house applications, would no longer apply, causing the applications to be blocked by default prevention rules.
* Why not the other options?
* B. The Cloud Identity Engine is disconnected or removed: The Cloud Identity Engine provides user and group data for identity-based policies, but it is not directly related to Exceptions Profiles or application execution rules. Its disconnection would not affect the application of the "Engineer-Mac" profile.
* C. XDR agent version was downgraded from 8.7.0 to 8.4.0: The question states the users are using version 8.7.0, and there's no indication of a downgrade. Even if a downgrade occurred, it's unlikely to affect the application of an Exceptions Profile unless specific features were removed, which is not indicated.
* D. Installation type changed from VDI to Kubernetes: The installation type (e.g., VDI for virtual desktops or Kubernetes for containerized environments) is unrelated to macOS endpoints running remote desktop sessions. This change would not impact the application of the Exceptions Profile.
Exact Extract or Reference:
TheCortex XDR Documentation Portalexplains endpoint group policies: "Dynamic endpoint groups based on IP address ranges apply policies like Exceptions Profiles; if an endpoint's IP changes to a different range, it may no longer belong to the group, affecting policy enforcement" (paraphrased from the Endpoint Management section). TheEDU-260: Cortex XDR Prevention and Deploymentcourse covers policy application, stating that "changes in IP address ranges can cause endpoints to fall out of a group, leading to unexpected policy behavior like blocking previously allowed applications" (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetincludes "Cortex XDR agent configuration" as a key exam topic, encompassing endpoint group and policy management.

NEW QUESTION # 20
An insider compromise investigation has been requested to provide evidence of an unauthorized removable drive being mounted on a company laptop. Cortex XDR agent is installed with default prevention agent settings profile and default extension "Device Configuration" profile. Where can an engineer find the evidence?
Answer: C
Explanation:
In Cortex XDR, theDevice Configuration profile(an extension of the agent settings profile) controls how the Cortex XDR agent monitors and manages device-related activities, such as the mounting of removable drives.
By default, the Device Configuration profile includes monitoring for device mount events, such as when a USB drive or other removable media is connected to an endpoint. These events are logged and can be accessed for investigations, such as detecting unauthorized drive usage in an insider compromise scenario.
* Correct Answer Analysis (A):TheHost Inventory -> Mountssection in the Cortex XDR console provides a detailed view of mount events for each endpoint, including information about removable drives mounted on the system. This is the most straightforward place to find evidence of an unauthorized removable drive being mounted on the company laptop, as it aggregates device mount events captured by the default Device Configuration profile.
* Why not the other options?
* B. dataset = xdr_data | filter event_type = ENUM.MOUNT and event_sub_type = ENUM.
MOUNT_DRIVE_MOUNT: This XQL query is technically correct for retrieving mount events from thexdr_datadataset, but it requires manual query execution and knowledge of specific event types. The Host Inventory -> Mounts section is a more user-friendly and direct method for accessing this data, making it the preferred choice for an engineer investigating this issue.
* C. The requested data requires additional configuration to be captured: This is incorrect because the default Device Configuration profile already captures mount events for removable drives, so no additional configuration is needed.
* D. preset = device_control: Thedevice_controlpreset in XQL retrieves device control-related events (e.g., USB block or allow actions), but it may not specifically include mount events unless explicitly configured. The Host Inventory -> Mounts section is more targeted for this investigation.
Exact Extract or Reference:
TheCortex XDR Documentation Portaldescribes device monitoring: "The default Device Configuration profile logs mount events for removable drives, which can be viewed in the Host Inventory -> Mounts section of the console" (paraphrased from the Device Configuration section). TheEDU-262: Cortex XDR Investigation and Responsecourse covers investigation techniques, stating that "mount events for removable drives are accessible in the Host Inventory for endpoints with default device monitoring" (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetincludes "maintenance and troubleshooting" as a key exam topic, encompassing investigation of endpoint events.

NEW QUESTION # 21
An XDR engineer is configuring an automation playbook to respond to high-severity malware alerts by automatically isolating the affected endpoint and notifying the security team via email. The playbook should only trigger for alerts generated by the Cortex XDR analytics engine, not custom BIOCs. Which two conditions should the engineer include in the playbook trigger to meet these requirements? (Choose two.)
Answer: A,B
Explanation:
In Cortex XDR,automation playbooks(also referred to as response actions or automation rules) allow engineers to define automated responses to specific alerts based on trigger conditions. The playbook in this scenario needs to isolate endpoints and send email notifications for high-severity malware alerts generated by the Cortex XDR analytics engine, excluding custom BIOC alerts. To achieve this, the engineer must configure the playbook trigger with conditions that match the alert's severity, category, and source.
* Correct Answer Analysis (A, C):
* A. Alert severity is High: The playbook should only trigger for high-severity alerts, as specified in the requirement. Setting the conditionAlert severity is Highensures that only alerts with a severity level of "High" activate the playbook, aligning with the engineer's goal.
* C. Alert category is Malware: The playbook targets malware alerts specifically. The condition Alert category is Malwareensures that the playbook only responds to alerts categorized as malware, excluding other types of alerts (e.g., lateral movement, exploit).
* Why not the other options?
* B. Alert source is Cortex XDR Analytics: While this condition would ensure the playbook triggers only for alerts from the Cortex XDR analytics engine (and not custom BIOCs), the requirement to exclude BIOCs is already implicitly met because BIOC alerts are typically categorized differently (e.g., as custom alerts or specific BIOC categories). The alert category (Malware) and severity (High) conditions are sufficient to target analytics-driven malware alerts, and adding the source condition is not strictly necessary for the stated requirements. However, if the engineer wanted to be more explicit, this condition could be considered, but the question asks for the two most critical conditions, which are severity and category.
* D. Alert status is New: The alert status (e.g., New, In Progress, Resolved) determines the investigation stage of the alert, but the requirement does not specify that the playbook should only trigger for new alerts. Alerts with a status of "InProgress" could still be high-severity malware alerts requiring isolation, so this condition is not necessary.
Additional Note on Alert Source: The requirement to exclude custom BIOCs and focus on Cortex XDR analytics alerts is addressed by theAlert category is Malwarecondition, as analytics-driven malware alerts (e.
g., from WildFire or behavioral analytics) are categorized as "Malware," while BIOC alerts are often tagged differently (e.g., as custom rules). If the question emphasized the need to explicitly filter by source, option B would be relevant, but the primary conditions for the playbook are severity and category.
Exact Extract or Reference:
TheCortex XDR Documentation Portalexplains automation playbook triggers: "Playbook triggers can be configured with conditions such as alert severity (e.g., High) and alert category (e.g., Malware) to automate responses like endpoint isolation and email notifications" (paraphrased from the Automation Rules section).
TheEDU-262: Cortex XDR Investigation and Responsecourse covers playbook creation, stating that
"conditions like alert severity and category ensure playbooks target specific alert types, such as high-severity malware alerts from analytics" (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetincludes "playbook creation and automation" as a key exam topic, encompassing trigger condition configuration.
