Questions # 1:

Based on the _raw_log and XQL query information below, what will be the result(s) of the temp_value?

Question # 1

Options:

123

192.168.10.1

10.120.80.2

149.235.219.208

59977

Answer

Explanation

The XQL query uses regextract with conditions to check if the source IP begins with 149.235. When true, it assigns the replacement value 192.168.10.1, otherwise it extracts the source port. From the given logs, this produces 123 (from the port extraction in the second log) and 192.168.10.1 (replacement for the first log’s matching source IP).

Questions # 2:

Which common issue can result in sudden data ingestion loss for a data source that was previously successful?

Options:

Data source is using an unsupported data format.

Data source has reached its maximum storage capacity.

Data source has reached its end of life for support.

API key used for the integration has expired.

Answer

Explanation

A sudden data ingestion loss for a previously successful data source commonly occurs when the API key used for the integration has expired, breaking authentication and preventing further log collection.

Questions # 3:

Administrators from Building 3 have been added to Cortex XSIAM to perform limited functions on a subset of endpoints. Custom roles have been created and applied to the administrators to limit their permissions, but their access should also be constrained through the principle of least privilege according to the endpoints they are allowed to manage. All endpoints are part of an endpoint group named "Building3," and some endpoints may also be members of other endpoint groups.

Which technical control will restrict the ability of the administrators to manage endpoints outside of their area of responsibility, while maintaining visibility to Building 3's endpoints?

Options:

SBAC enabled in Building 3's IP range with the "EG:Building3" tag assigned to each administrator's scope

SBAC enabled in Permissive Mode with the "EG:Building3" tag assigned to each administrator's scope

SBAC enabled in Restrictive Mode with the "EG:Building3" tag assigned to each administrator's scope

SBAC enabled globally with the "EG:Building3" tag assigned to each administrator's scope

Answer

Explanation

To enforce least privilege for Building 3 administrators, SBAC must be enabled in Restrictive Mode and the administrators’ scope must be limited to EG:Building3. This ensures they can only manage endpoints within the Building 3 group, even if those endpoints are also part of other groups, while blocking access to endpoints outside their responsibility.

Questions # 4:

An application which ingests custom application logs is hosted in an on-premises virtual environment on an Ubuntu server, and it logs locally to a .csv file.

Which set of actions will allow the ingestion of the .csv logs into Cortex XSIAM directly from the server?

An application which ingests custom application logs is hosted in an on-premises virtual environment on an Ubuntu server, and it logs locally to a .csv file.

Which set of actions will allow the ingestion of the .csv logs into Cortex XSIAM directly from the server?

Options:

Install a Broker VM in the environment, and configure the CSV Collector to collect the files of interest.

Install a Cortex XDR agent on the Ubuntu server, and configure the agent to collect the files of interest.

Install a Broker VM in the environment, and migrate the application to the Broker VM.

Install XDR Collector on the Ubuntu server, and configure the agent to collect the files of interest.

Answer

Explanation

The correct approach is to install a Broker VM in the environment and configure its CSV Collector applet to ingest the .csv log files directly from the Ubuntu server. This enables secure ingestion of custom application logs into Cortex XSIAM without modifying the application or requiring an XDR agent on the server.

Questions # 5:

In the Incident War Room, which command is used to update incident fields identified in the incident layout?

Options:

!setIncidentFields

!setParentIncidentFields

!setParentIncidentContext

!updateParentIncidentFields

Answer

Explanation

The !setIncidentFields command is used in the Incident War Room to directly update incident fields that are defined in the incident layout, ensuring the incident record reflects the latest information.

Questions # 6:

Which cytool command will look up the policy being applied to a Cortex XDR agent?

Options:

cytool adaptive_policy interval 0

cytool payload_execution query

cytool adaptive_policy recalc

cytool persist print agent_settings.db

Answer

Explanation

The cytool adaptive_policy recalc command is used to look up and recalculate the policy being applied to a Cortex XDR agent, allowing engineers to verify the active policy enforcement on the endpoint.

Questions # 7:

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

Options:

Add 'ExtractIndicators': False to the script.

Add 'IgnoreAutoExtract': True to the script.

Use 'AutoExtract': False in the script.

Set 'IndicatorExtraction': None in the script.

Answer

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.

Questions # 8:

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?

Options:

Contact Palo Alto Networks Support to create an exception to revert to the previously installed version.

Back up the current configuration and data, then revert to the previously installed version.

Remove all integrations and playbooks associated with the content pack, then revert to the previously installed version.

Directly reinstall the previously installed version over the current one.

Answer

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.

Questions # 9:

What is the function of the "MODEL" section when creating a data model rule?

Options:

To make a list of all the relevant fields to be mapped from the logs to XDM

To define the mapping between a single dataset and XDM

To finalize rule definition with all XQL statements

To map log fields to corresponding Cortex XSIAM Data Model (XDM) fields

Answer

Explanation

The MODEL section in a data model rule is used to map log fields to the corresponding Cortex XSIAM Data Model (XDM) fields. This ensures that ingested data aligns with XDM, enabling consistent analytics, detections, and queries across different data sources.

Questions # 10:

Which section of a parsing rule defines the newly created dataset?

Options:

RULE

COLLECT

INGEST

CONST

Answer

Explanation

In a Cortex XSIAM parsing rule, the COLLECT section defines the newly created dataset. This section specifies how the parsed fields and data should be structured and stored for further use in analytics and queries.
