XSIAM-Engineer Palo Alto Networks XSIAM Engineer Questions and Answers

The "partially protected" status on a Linux endpoint typically occurs when the kernel modules fail to load because of unsupported kernel versions or when the agent is outdated and requires an upgrade. Both conditions prevent the agent from providing full protection capabilities.

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.

Setting the "--memory-swap" option to "-1" during Cortex XSIAM engine deployment configures the container to run without requiring swap capabilities. This ensures the engine operates fully within allocated RAM, improving stability and avoiding issues related to memory swapping.

To meet the requirements, the engineer must enable scope enforcement by setting SBAC mode to Restrictive and assigning the Europe endpoint group (EG:Europe) as the scope. For role assignment, the correct predefined role is Privileged IT Admin, since it allows endpoint management, policy creation, and Live Terminal but does not permit user role management.

Cortex XSIAM allows configuring Email and Slack as direct alert notification options without requiring a playbook. PagerDuty and SMS integrations, however, require orchestration through playbooks.

In a For Each Input loop, each iteration takes the next value from the list inputs while keeping constant inputs unchanged.

On the second iteration:

x = X (second value of W,X,Y,Z)

y = b (second value of a,b,c,d)

z = 9 (constant for all iterations).

So, the values are X, b, 9.

When a disable injection and prevention rule is applied to a running process, the security capabilities are detached for the lifetime of that process. Even after disabling the rule, the capabilities are not reapplied automatically; the process must be restarted to restore security enforcement.

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).

In a Broker VM cluster, the Syslog Collector applet runs in active/standby mode (active on the primary node, standby on others), while the Kafka Collector applet runs in active/active mode (active on all nodes). This design ensures both high availability and scalability for ingestion.

To use a custom script in an alert layout, the script must be tagged with "general-purpose-dynamic-section", then a general purpose dynamic section is added to the layout, and finally the section settings are edited to attach the automation script. This ensures the script executes and displays results dynamically within the alert layout.

Cortex XSIAM ingests structured third-party logs (such as CEF, LEEF, and JSON) by breaking down the key-value pairs and saving them in a normalized table format. This enables efficient correlation, analytics, and query performance across diverse log sources while preserving data fidelity.

The correct command is !ToTable data=${parentIncidentFields.custom_fields.incidentassignment}, which converts the specified context data into a tabular format. This allows fields such as runStatus and startDate to be clearly displayed in a table when troubleshooting playbook tasks.

For upgrading a non-Linux Kubernetes cluster, the correct installer type is Helm, since Helm charts are the supported method for deploying and managing Cortex XDR agents in Kubernetes environments.

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.
