Question No : 1

A Behavioral Threat Protection (BTP) alert is triggered with an action of "Prevented (Blocked)" on one of several application servers running Windows Server 2022. The investigation determines the involved processes to be legitimate core OS binaries, and the description from the triggered BTP rule is an acceptable risk for the company to allow the same activity in the future.
This type of activity is only expected on the endpoints that are members of the endpoint group "AppServers," which already has a separate prevention policy rule with an exceptions profile named "Exceptions-AppServers" and a malware profile named "Malware-AppServers."
The CGO that was terminated has the following properties:
SHA256: eb71ea69dd19f728ab9240565e8c7efb59821e19e3788e289301e1e74940c208
File path: C:\Windows\System32\cmd.exe
Digital Signer: Microsoft Corporation
How should the exception be created so that it is scoped as narrowly as possible to minimize the security gap?

A.Create the exception via the alert itself, selecting the CGO hash, CGO signer, CGO process path, and applying the scope to the "Exceptions-AppServers" profile.
B.Create a Disable Prevention Rule via Exceptions Configuration with the following selections:
C.Create a Legacy Agent Exception via Exceptions Configuration with the following selections:
D.Create the exception via the alert itself, selecting the CGO hash, CGO signer, CGO process path, and applying the scope to "Global."

정답:
Explanation:
The most secure approach is to create a Disable Prevention Rule via Exceptions Configuration, scoped specifically to the Exceptions-AppServers profile. This rule should include the hash (SHA256), signer (Microsoft Corporation), and file path (C:\Windows\System32\cmd.exe). This ensures the exception is applied only to the trusted, legitimate process on the AppServers group while minimizing the security gap.

Question No : 2

A Cortex XSIAM engineer at a SOC downgrades a critical threat intelligence content pack from the Cortex Marketplace while performing routine maintenance. As a result, the SOC team loses access to the latest threat intelligence data.
Which action will restore the functionality of the content pack to its previously installed version?

A.Contact Palo Alto Networks Support to create an exception to revert to the previously installed version.
B.Back up the current configuration and data, then revert to the previously installed version.
C.Remove all integrations and playbooks associated with the content pack, then revert to the previously installed version.
D.Directly reinstall the previously installed version over the current one.

정답:
Explanation:
To restore the content pack to its previously installed version, the engineer can directly reinstall the desired version from the Cortex Marketplace. Content packs support version management, allowing rollback or upgrade without requiring support intervention or removing existing configurations.

Question No : 5

The following string is a value of a key named "Data2" in the context:
{"@admin":"admin","@dirtyld":"1","@loc":"Lab","@name":"default#1","@oldname":"Test","@time":"2024 /08/28 07:45:15","alert":{"@admin":"admin","@dirtyld":"2","@time":"2024/08/28 07:45:15","member": {"#text":"
Based on the image below, what will be displayed in the "Test result" field when the "Test" button is pressed?

A.1
B."1
C.2
D."2

정답:
Explanation:
The applied transformers extract the value of @dirtyId from the root-level Data2 object. The sequence includes trimming using "Id:" and ending with a quotation mark ". As a result, the root @dirtyId value (1) is returned with a leading quotation mark, so the Test result will display "1.

What should be considered when creating a custom incident domain?

A.Alert grouping will not apply, but SmartScore will.
B.Alert grouping will apply, but SmartScore will not.
C.Alert grouping and SmartScore will not be applied to incidents.
D.Alert grouping and SmartScore will be applied to incidents.

정답:
Explanation:
When creating a custom incident domain in Cortex XSIAM, alert grouping still applies, allowing related alerts to be combined into incidents. However, SmartScore is not applied, since it is reserved for predefined domains.

Question No : 9

Cortex XSIAM has not received any logs for 30 minutes from a Palo Alto Networks NGFW named "MainFW.” An engineer wants to create an alert for this scenario.
Correlation rule settings include:

Time Schedule: Every 30 minutes

Query Timeframe: 30 minutes

Action: Generate alert

Alert Name: No logs received from MainFW in the past 30 minutes
Which query should be used in the correlation rule?
A)

B)

C)

D)

A.Option A
B.Option B
C.Option C
D.Option D

정답:
Explanation:
The correct query is the one using preset = metrics_view with comp sum(total_event_count) as total_events by _reporting_device_name and filtering total_events = 0.
This query directly checks event counts reported by the NGFW ("MainFW"). If no logs are received in the last 30 minutes, the total event count will be 0, which triggers the correlation rule alert.

Question No : 10

What is the purpose of using rolling tokens to manage Cortex XDR agents?

A.To periodically rotate encryption keys used for tenant communication
B.To perform administration on agents without requiring static credentials
C.To authorize agents to download and install content updates D To temporarily disable the agents during maintenance windows

정답:
Explanation:
Rolling tokens in Cortex XDR are used to perform administration on agents without relying on static credentials. This improves security by providing time-limited, automatically rotating tokens that maintain agent management access without exposing long-lived credentials.

Explanation:
In the query action_local_port in (1122, 2234), the word "in" functions as an operator. It checks whether the field action_local_port matches any value in the specified list (1122, 2234).

Question No : 14

A systems engineer overseeing the integration of data from various sources through data pipelines into Cortex XSIAM notices modifications occurring during the ingestion process, and these modifications reduce the accuracy of threat detection and response. The engineer needs to assess the risks associated with the pre-ingestion data modifications and develop effective solutions for data integrity and system efficacy.
Which set of steps must be followed to meet these goals?

A.Develop an advanced monitoring system to track and log all changes made to data during ingestion, and use analytics to compare pre- and post-ingestion states based on XDM to identify and mitigate discrepancies.
B.Design a hybrid approach for critical data fields to be safeguarded against modifications during ingestion, while less critical data fields undergo allowable modifications that are rectified post-ingestion by using XDM to balance performance with data integrity.
C.Implement a pre-ingestion data validation process that aligns with the post-ingestion standards set by XDM, ensuring data consistency and integrity before it enters Cortex XSIA
D.Establish a process to minimize data modifications during ingestion, prioritizing raw data capture and using XDM post-ingestion for necessary transformations and integrity checks.

정답:
Explanation:
The best approach is to minimize data modifications during ingestion, prioritizing raw data capture to preserve accuracy. Then, apply XDM (XSIAM Data Model) transformations and integrity checks post-ingestion. This ensures that threat detection and response are based on unaltered, high-fidelity data while still enabling normalization and enrichment after ingestion.

Question No : 15

Which action will prevent the automatic extraction of indicators such as IP addresses and URLs from a script's output?

A.Add 'ExtractIndicators': False to the script.
B.Add 'IgnoreAutoExtract': True to the script.
C.Use 'AutoExtract': False in the script.
D.Set 'IndicatorExtraction': None in the script.

정답:
Explanation:
To prevent Cortex XSIAM from automatically extracting indicators (like IPs, domains, and URLs) from a script’s output, you must use 'AutoExtract': False in the script. This disables the auto-extraction mechanism for that script.
