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typically occurs when the kernel modules fail to load because of unsupported kernel versions or when the agent is outdated and requires an upgrade.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.

Reputation commands such as !ip rely on a configured and enabled reputation integration instance (for example, VirusTotal, Palo Alto WildFire, or other threat intel sources). If no such instance is available, the command execution will fail, since it cannot retrieve enrichment data.

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.

To enable Cloud Identity Engine on Cortex XSIAM, it must first be activated on HUB, Palo Alto Networks’ centralized service management platform. Once activated, it can be configured and integrated with Cortex XSIAM for identity-based visibility and enforcement.

Broker VM options appear greyed out in the Agent Settings profile when the Local Agent Settings applet is activated without an FQDN. An FQDN is required for agents to resolve and connect to the Broker VM as a download source.

To migrate XDR agents without internet from tenant A to tenant B, the engineer must install a new Broker C registered to tenant B to establish communication, and also register Broker A with tenant B so existing agents can transition their communication path smoothly during migration.

The correct command is cytool import suex -path , which imports a supplied support exception (suex) file onto a Linux endpoint, ensuring the exception is applied locally.

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.

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.

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).

The parsing_rules_errors dataset records compilation errors that occur when a parsing rule cannot be properly built or executed. This helps engineers identify and fix issues in rule definitions before logs are processed.

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.

In Cortex XSIAM’s Alert Layout Builder, the "War Room" and "Work Plan" tabs are optional and can be removed, while the "Alert Info" tab is mandatory and cannot be deleted. This ensures that essential alert details are always retained, while collaboration and workflow tabs can be customized.
