What occurs when QRadar reaches the events per second (EPS) or flows per minute (FPM) shared license pool limits?

  1. Incremental Licensing removes the limits on EPS and FPM.
  2. QRadar generates a notification that the limit was reached and stops processing.
  3. Data accumulates in a temporary burst handing queue, but QRadar continues to process events and flows.
  4. Events and flows continue to process, and the Network and Log Activity tabs remain active.

Answer(s): C

Explanation:

When IBM QRadar SIEM V7.5 reaches the events per second (EPS) or flows per minute (FPM) shared license pool limits, the following occurs:

Burst Handling Queue: QRadar utilizes a temporary burst handling queue to manage the overflow of events and flows. This queue temporarily holds data until the system can process it.

Continued Processing: QRadar continues to process events and flows despite reaching the license limits, ensuring no data is lost.

Efficiency: This mechanism allows QRadar to handle short-term spikes in data volume without compromising the integrity or continuity of event and flow processing.

Reference
The handling of EPS and FPM limits is described in IBM QRadar SIEM's system administration and configuration guides, which explain how QRadar manages data when license thresholds are exceeded.



Which three (3) resource restriction types are available in QRadar?

  1. Role-based restrictions
  2. Tenant-based restrictions
  3. User-based restrictions
  4. Service-based restrictions
  5. Event-based restrictions
  6. Domain-based restrictions

Answer(s): A,B,F

Explanation:

IBM QRadar SIEM V7.5 provides several types of resource restriction mechanisms to manage access control and data visibility. The three main types are:

Role-based restrictions: These restrictions limit what actions users can perform based on their assigned roles. Each role has specific permissions that dictate access to different functionalities and data within QRadar.

Tenant-based restrictions: This type of restriction is used in multi-tenant environments, where different tenants (organizational units) need to have isolated views and access to their data. Tenant-

based restrictions ensure that users from one tenant cannot access data from another tenant.

Domain-based restrictions: Domains in QRadar are used to segment data logically. Domain-based restrictions control which data is visible to users based on the domains they have been granted access to.

These restriction types ensure that access control is granular and adheres to organizational security policies.

Reference
IBM QRadar SIEM documentation outlines the use of role-based, tenant-based, and domain-based restrictions for managing access control and data visibility.



How can you configure a log source to provide events to different domains?

  1. Create a saved search on the Network Activity tab to view events in specific domains.
  2. Use the Assistant app to update the domain information for the log source.
  3. Use custom properties to assign events from a single log source to different domains.
  4. Use the Use Case Manager app to update building blocks to support multi domain events.

Answer(s): C

Explanation:

To configure a log source in IBM QRadar SIEM V7.5 to provide events to different domains, administrators can use custom properties. Here's how it works:

Custom Properties: Create and configure custom properties to tag events with specific domain information.

Assigning Events: When events are ingested from a log source, these custom properties can be used to dynamically assign events to different domains based on predefined criteria.

Domain Management: This approach allows flexibility in managing and segregating data from a single log source across multiple domains, ensuring that each domain receives the relevant events.

Reference
The configuration of custom properties for domain assignment is detailed in the QRadar SIEM administration guides, providing step-by-step instructions for setting up and using custom properties for domain management.



An administrator receives a file with all the vital assets in the company and wants to import this file into QRadar. How must this import file be formatted?

  1. CSV file in the format: IP address. Name, Weight. Description
  2. JSON file in the format: IP address. Name, Weight, Domain
  3. XML file in the format: IP address. Name, Weight, Domain
  4. XLS file in the format: IP address, Name. Weight, Description

Answer(s): A

Explanation:

When importing vital asset information into IBM QRadar SIEM V7.5, the import file must be formatted as a CSV file with the following structure:

Format: CSV (Comma-Separated Values)

Fields: The required fields are IP address, Name, Weight, and Description.

IP address: The IP address of the asset.

Name: The name of the asset.

Weight: A numerical value representing the importance or criticality of the asset.

Description: A brief description of the asset.

This format ensures that QRadar can correctly parse and import the asset information, integrating it into its asset database for further analysis and correlation.

Reference

IBM QRadar SIEM documentation provides guidelines on the required CSV format for importing asset information, detailing the necessary fields and their order.
