To ingest additional events from a Windows DHCP server into Cortex XDR with minimal configuration, the recommended approach is to use theCortex XDR Collector. TheXDR Collectoris a lightweight component designed to collect and forward logs and events from various sources, including Windows servers, to Cortex XDR for analysis and correlation. It is specifically optimized for scenarios where full Cortex XDR agent deployment is not required, and it minimizes configuration overhead by automating much of the data collection process.

For a Windows DHCP server, the XDR Collector can be installed on the server to collect DHCP logs (e.g., lease assignments, renewals, or errors) from the Windows Event Log or other relevant sources. Once installed, the collector forwards these events to the Cortex XDR tenant with minimal setup, requiring only basic configuration such as specifying the target data types and ensuring network connectivity to the Cortex XDR cloud. This approach is more straightforward than alternatives like setting up a full agent or configuring external integrations like Windows Event Collector (WEC) or HTTP collectors, which require additional infrastructure or manual configuration.

Why not the other options?

A. Activate Windows Event Collector (WEC): While WEC can collect events from Windows servers, it requires significant configuration, including setting up a WEC server, configuring subscriptions, and integrating with Cortex XDR via a separate ingestion mechanism. This is not minimal configuration.

C. Enable HTTP collector integration: HTTP collector integration is used for ingesting data via HTTP/HTTPS APIs, which is not applicable for Windows DHCP server events, as DHCP logs are typically stored in the Windows Event Log, not exposed via HTTP.

D. Install the Cortex XDR agent: The Cortex XDR agent is a full-featured endpoint protection and detection solution that includes prevention, detection, and responsecapabilities. While it can collect some event data, it is overkill for the specific task of ingesting DHCP server events and requires more configuration than the XDR Collector.

Exact Extract or Reference:

TheCortex XDR Documentation Portaldescribes theXDR Collectoras a tool for “collecting logs and events from servers and endpoints with minimal setup” (paraphrased from the Data Ingestion section). TheEDU-260: Cortex XDR Prevention and Deploymentcourse emphasizes that “XDR Collectors are ideal for ingesting server logs, such as those from Windows DHCP servers, with streamlined configuration” (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetlists “data source onboarding and integration configuration” as a key skill, which includes configuring XDR Collectors for log ingestion.

Cortex XDR agents on Linux consist of several services that handle different aspects of agent functionality, such as event collection, policy enforcement, and health monitoring.Memory monitoringfor agent health involves tracking the memory usage of the agent’s core processes to ensure they are operating within acceptable limits, which is critical for maintaining agent stability and performance. Thepmd(Process Monitoring Daemon) service is responsible for monitoring the agent’s health, including memory usage, on Linux systems.

Correct Answer Analysis (D):Thepmdservice should be monitored to fulfill the request for memory monitoring. The Process Monitoring Daemon tracks the Cortex XDR agent’s resource usage, including memory consumption, and reports health metrics to the console. Monitoring this service ensures the agent remains healthy and can detect issues like memory leaks or excessive resource usage.

Why not the other options?

A. dypdng: This is not a valid Cortex XDR service on Linux. It appears to be a typo or a misnamed service.

B. clad: The clad service (Cortex Linux Agent Daemon) is responsible for core agent operations, such as communication with the Cortex XDR tenant, but it is not specifically focused on memory monitoring for health purposes.

C. pyxd: The pyxd service handles Python-based components of the agent, such asscript execution for certain detections, but it is not responsible for memory monitoring or agent health.

Exact Extract or Reference:

TheCortex XDR Documentation Portalexplains Linux agent services: “The pmd (Process Monitoring Daemon) service on Linux monitors agent health, including memory usage, to ensure stable operation” (paraphrased from the Linux Agent Deployment section). TheEDU-260: Cortex XDR Prevention and Deploymentcourse covers Linux agent setup, stating that “pmd is the service to monitor for agent health, including memory usage, on Linux systems” (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetincludes “planning and installation” as a key exam topic, encompassing Linux agent deployment and monitoring.

In Cortex XDR,dashboard drilldownsallow users to interact with widgets (e.g., charts or tables) by clicking on elements to access additional details or perform actions. Drilldowns enhance the investigative capabilities of dashboards by linking to related data or views.

Correct Answer Analysis (A, C):

A. Navigate to a different dashboard: A drilldown can be configured to navigate to another dashboard, providing a more detailed view or related metrics. For example, clicking on an alert count in a widget might open a dashboard focused on alert details.

C. Link to an XQL query: Drilldowns often link to anXQL querythat filters data based on the clicked element (e.g., an alert name or source). This allows users to view raw events or detailed records in the Query Builder or Investigation view.

Why not the other options?

B. Initiate automated response actions: Drilldowns are primarily for navigation and data exploration, not for triggering automated response actions. Response actions (e.g., isolating an endpoint) are typically initiated from the Incident or Alert views, not dashboards.

D. Send alerts to console users: Drilldowns do not send alerts to users. Alerts are generated by correlation rules or BIOCs, and dashboards are used for visualization, not alert distribution.

Exact Extract or Reference:

TheCortex XDR Documentation Portaldescribes drilldown functionality: “Dashboard drilldowns can navigate to another dashboard or link to an XQL query to display detailed data based on the selected widget element” (paraphrased from the Dashboards and Widgets section). TheEDU-262: Cortex XDR Investigation and Responsecourse covers dashboards, stating that “drilldowns enable navigation to other dashboards or XQL queries for deeper analysis” (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetincludes “dashboards and reporting” as a key exam topic, encompassing drilldown configuration.
