Question 1

What are some of the supported custom property expression types in QRadar?


Correct : B

IBM QRadar SIEM supports various types of custom property expressions to allow users to extract and parse data from logs in flexible and powerful ways. Among the supported custom property expression types, Regex, JSON, and LEEF are frequently utilized:

Regex (Regular Expressions): Regular expressions are a powerful tool used for pattern matching and extraction in text. In QRadar, regex can be used to create custom properties that parse specific patterns from log data, allowing for detailed and precise data extraction.

JSON (JavaScript Object Notation): JSON is a widely used data interchange format that is lightweight and easy to read and write. QRadar supports JSON expressions to parse and extract structured data from logs formatted in JSON.

LEEF (Log Event Extended Format): LEEF is a log format used by various devices to structure log data in a consistent manner. QRadar can utilize LEEF expressions to extract data from logs that use this format.

These types of expressions enhance QRadar's ability to handle diverse log formats and enable more accurate and efficient data analysis.

Question 2

How can an administrator configure a rule response to add event data to a reference set?


Correct : D

Administrators can configure a rule response in QRadar to add event data to a reference set by using the 'add to reference set' rule response. This is a predefined response action in QRadar that allows specific event data to be added to a reference set when the rule conditions are met.

Navigate to the 'Offenses' tab in the QRadar console.

Select 'Rules' from the navigation pane.

Create a new rule or edit an existing rule.

In the 'Rule Response' section, add a new response.

Select the 'Add to Reference Set' response.

Specify the reference set and the data to be added.

Save and deploy the rule.

Question 3

Domain assignments lake precedence over the settings of which other elements from a security profile?


Correct : D

In IBM QRadar SIEM, domain assignments take precedence over the settings of other elements from a security profile, specifically Permission Precedence, Networks, and Log Sources tabs. This hierarchical precedence ensures that the domain settings are enforced across different security configurations. The domain settings effectively override other configurations to maintain consistency and security across the environment. This structure helps in managing access and permissions more effectively by ensuring that the domain-level policies are the primary controlling factor.

Question 4

An administrator is reviewing the system notifications and discovers this error:

Insufficient disk space to complete data export request.

The Export Directory property in the System Settings has the default configuration.

Which disk partition does the administrator need to check?


Correct : A

When the error 'Insufficient disk space to complete data export request' is encountered, and the Export Directory property in the System Settings has the default configuration, the disk partition that needs to be checked is /store/ariel/events/exports. This directory is typically used for exporting event data in QRadar SIEM. The error indicates that the available disk space in this partition is insufficient to handle the export operation. Administrators should check the storage usage of this partition and manage the space by either cleaning up unnecessary files or expanding the storage capacity.

Question 5

Which field is mandatory when you use the DSM Editor to map an event to a OID?


Correct : D

When using the DSM (Device Support Module) Editor in IBM QRadar to map an event to an OID (Object Identifier), the Event ID field is mandatory. The Event ID uniquely identifies the event within QRadar and is essential for ensuring that the correct event data is associated with the appropriate OID. This mapping process allows QRadar to properly categorize and handle events based on their unique identifiers.
