XSIAM-Engineer Questions and Answers

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 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).

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.

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.

The correct command is cytool config proxy --host crtxbroker01.company.net --port 8888, which configures the Cortex XDR agent to route its traffic through the Broker VM acting as a proxy. This allows the agent to register and download updates without requiring direct internet access.

During Cortex XSIAM tenant activation, data at rest is configured with AES 128 encryption by selecting "BYOK" (Bring Your Own Key) under the Advanced → Encryption Method option and following the wizard’s instructions. This ensures secure key management and compliance with encryption standards.

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.

The correct query is the preset = host_inventory_applications with filters for application_name contains "ai_app" and version in ("12.1", "12.2", "12.4", "12.5"). This directly identifies hosts that have the vulnerable application and specific versions installed, matching the analyst’s request to find assets exposed to the zero-day CVE.

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.

The Multi-select option allows a dashboard widget in Cortex XSIAM to be filtered by more than one dynamic value, enabling flexible data exploration and visualization across multiple selected criteria.

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.

When a playbook execution reaches a breakpoint on a non-manual task, you can skip the task with the breakpoint to allow the playbook to continue, or manually trigger continuation using "Run Script Now" or "Complete Manually". These actions resume execution without restarting the entire playbook.
