IBM C1000-156 IBM Security QRadar SIEM V7.5 Administration Exam Practice Test

Answer : D

If the option 'Include in my Dashboard' cannot be selected when creating a saved search in IBM QRadar SIEM V7.5, a possible reason is insufficient permissions. Here's why:

Permissions: The user needs appropriate permissions to add saved searches to the dashboard.

Role-Based Access Control: QRadar uses role-based access control to manage user permissions. The user's role must include the necessary privileges to modify dashboards.

Verification: Ensure that the user has the correct permissions assigned. This can be checked and adjusted in the user management settings.

Reference IBM QRadar SIEM administration guides explain the permissions required for various actions, including adding saved searches to dashboards, and how to configure user roles and permissions.

Answer : C

In IBM QRadar SIEM V7.5, using a quick filter search requires the correct syntax to find specific elements within the event logs. The correct string to search for the elements 10.100.100.*, Bluecoat, and TCP_REFRESH_MIS is:

String Structure: '10.100.100.*%AND%Bluecoat%AND%TCP_REFRESH_MIS'

Elements: This string combines the IP address pattern, device type, and specific event message using %AND% to ensure that all three elements are included in the search results.

Quotation Marks: The quotation marks are necessary to group the search terms and ensure that the search engine interprets them correctly.

Reference IBM QRadar SIEM search documentation provides guidelines on using quick filter searches and the correct syntax for combining multiple search terms.

Answer : A

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.

Answer : C

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.

Answer : A, B, F

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.

Answer : D

In IBM QRadar SIEM V7.5, the default value for the maximum number of active offenses is set to 2500. This limit is in place to manage system performance and ensure efficient processing of security incidents. Here's the detailed information:

Default Setting: The default setting for the maximum number of active offenses is 2500.

Impact: If this limit is reached, QRadar will not generate new offenses until some of the existing offenses are closed or archived.

Configuration: Administrators can adjust this setting based on their organizational needs, but the default value is 2500.

Reference This information is detailed in the QRadar SIEM configuration and tuning guides, which specify default settings and provide instructions for modifying the maximum number of active offenses if necessary.

Answer : C

In IBM QRadar SIEM V7.5, the license giveback rate can be viewed in the License Pool Management section. Here's the step-by-step process:

Access Admin Tab: The administrator needs to navigate to the Admin tab in the QRadar GUI.

License Pool Management: Under the Admin tab, there is an option for License Pool Management.

View License Giveback Rate: Within the License Pool Management section, the administrator can view details about license usage, including the giveback rate.

Reference The QRadar SIEM administration guide provides detailed steps on accessing and managing license information, including the giveback rate, under the Admin tab.
