NEW QUESTION # 45
Log events from a previously deployed Windows XDR Collector agent are no longer being observed in the console after an OS upgrade. Which aspect of the log events is the probable cause of this behavior?
Answer: B
Explanation:
After a Windows OS upgrade, previously configured XDR Collector log sources may begin generating larger log events. Cortex XDR Collector has limitations on the size of events it can process and forward. Events that exceed the supported maximum size (commonly referenced as
5 MB) may be dropped and therefore no longer appear in the Cortex XDR console.
NEW QUESTION # 46
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]
Answer: B,C
Explanation:
When dealing with a false positive triggered by a Custom Prevention rule (which blocks activity on an endpoint via an assigned BIOC rule inside a Restrictions profile), you have two primary methods to tune out the authorized behavior:
In Cortex XDR, you can create an exception directly from the generated alert or incident. An alert exception allows you to define specific criteria (such as the specific authorized endpoint name, file path, or user) to safely bypass the prevention policy without disabling the rule entirely for the rest of the company.
Since the rule relies entirely on the custom BIOC query logic you built, you can edit the BIOC definition itself. By adding an exclusion rule directly within the BIOC logic (e.g., adding an AND NOT condition for a specific authorized process path or signing certificate), you prevent the rule from matching that authorized behavior in the future.
NEW QUESTION # 47
Which external threat intelligence source is available out-of-the-box to supplement WildFire verdicts for key artifacts in an incident?
Answer: A
Explanation:
VirusTotal is available as an out-of-the-box external threat intelligence enrichment source for key incident artifacts, supplementing WildFire verdicts with additional reputation and analysis context.
NEW QUESTION # 48
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]
Answer: C,D
Explanation:
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.

NEW QUESTION # 49
A malware profile is configured with all the default settings for a specific endpoint group. For the same group, a restrictions profile has also been configured with the defaults, except with the restriction as shown in the image below. A user opens a command prompt and runs a mimikatz executable from C:\temp.
What is the first alert produced on the XDR Console for that endpoint?
Answer: D
Explanation:
The Restrictions profile blocks executable execution from the configured restricted location. Since the Mimikatz executable is launched from C:\temp and matches the restricted path rule, the first alert generated is for attempted execution from a restricted folder.
