質問 # 10
The most recent Cortex XDR agents are being installed at a newly acquired company. A list with endpoint types (i.e., OS, hardware, software) is provided to the engineer. What should be cross- referenced for the Linux systems listed regarding the OS types and OS versions supported?
正解：D
解説：
For Linux systems specifically, the critical compatibility check is the Kernel Module Version Support document. Unlike Windows or macOS, Linux has significant variability in kernel versions across distributions, and the Cortex XDR agent relies on kernel modules that must be compatible with the specific kernel version running on each endpoint.
質問 # 11
A Custom Prevention rule that was determined to be a false positive alert needs to be tuned. The behavior was determined to be authorized and expected on the affected endpoint. Based on the image below, which two steps could be taken? (Choose two.)
[Image description: A Custom Prevention rule configuration, assumed to trigger a Behavioral Indicator of Compromise (BIOC) alert for authorized behavior]
正解：A、D
解説：
In Cortex XDR, aCustom Prevention ruleoften leveragesBehavioral Indicators of Compromise (BIOCs)to detect specific patterns or behaviors on endpoints. When a rule generates a false positive alert for authorized and expected behavior, tuning is required to prevent future false alerts. The question assumes the alert is related to a BIOC triggered by the Custom Prevention rule, and the goal is to suppress or refine the alert without disrupting security.
* Correct Answer Analysis (A, B):
* A. Apply an alert exception: Analert exceptioncan be created in Cortex XDR to suppress alerts for specific conditions, such as a particular endpoint, user, or behavior. This is a quick way to prevent false positive alerts for authorized behavior without modifying the underlying rule, ensuring the behavior is ignored in future detections.
* B. Apply an alert exclusion to the XDR behavioral indicator of compromise (BIOC) alert:
Analert exclusionspecifically targets BIOC alerts, allowing administrators to exclude certain BIOCs from triggering alerts on specific endpoints or under specific conditions. This is an effective way to tune the Custom Prevention rule by suppressing the BIOC alert for the authorized behavior.
* Why not the other options?
* C. Apply an alert exclusion to the XDR agent alert: This option is incorrect because alert exclusions are applied to BIOCs or specific alert types, not to generic"XDR agent alerts." The term "XDR agent alert" is not a standard concept in Cortex XDR for exclusions, making this option invalid.
* D. Modify the behavioral indicator of compromise (BIOC) logic: While modifying the BIOC logic could prevent false positives, it risks altering the rule's effectiveness for other endpoints or scenarios. Since the behavior is authorized only on the affected endpoint, modifying the BIOC logic is less targeted than applying an exception or exclusion and is not one of the best steps in this context.
Exact Extract or Reference:
TheCortex XDR Documentation Portalexplains alert tuning: "Alert exceptions suppress alerts for specific conditions, such as authorized behaviors, without modifying rules. Alert exclusions can be applied to BIOC alerts to prevent false positives on specific endpoints" (paraphrased from the Alert Management section). The EDU-262: Cortex XDR Investigation and Responsecourse covers alert tuning, stating that "exceptions and BIOC exclusions are used to handle false positives for authorized behaviors" (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetincludes "detection engineering" as a key exam topic, encompassing alert tuning and BIOC management.

質問 # 12
Which statement describes the functionality of fixed filters and dashboard drilldowns in enhancing a dashboard's interactivity and data insights?
正解：C
解説：
Fixed filters let users choose predefined or dynamic values to change the dashboard scope, while dashboard drilldowns provide interactive insights or contextual navigation, such as linking to XQL searches.
The Cortex XDR documentation says fixed dashboard filters allow users to alter scope using predefined and dynamic values from the dashboard header.
質問 # 13
During the deployment of a Broker VM in a high availability (HA) environment, after configuring the Broker VM FQDN, an XDR engineer must ensure agent installer availability and efficient content caching to maintain performance consistency across failovers. Which additionalconfiguration steps should the engineer take?
正解：A
解説：
Cortex XDR's Broker VM HA cluster guidance says to use a load balancer FQDN and that, if you use a trusted CA-signed cert, you upload it to the Broker VM; self-signed certs require no extra steps, but HA still relies on the load balancer.
質問 # 14
What information can be used to create a dynamic endpoint group?
正解：D
解説：
Dynamic endpoint groups can be created using endpoint attributes such as IP address criteria, allowing endpoints to be automatically included when they match the defined network-based condition.
