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

Answer : C

In IBM QRadar SIEM V7.5, Anomaly Detection Engine rules that test events or flows for volume changes occurring in regular patterns are known as Anomaly Rules. Here's how they function:

Detection: Anomaly rules are designed to identify deviations from normal behavior by analyzing patterns in the data.

Volume Changes: These rules specifically look for unusual increases or decreases in event or flow volumes that might indicate potential security incidents.

Regular Patterns: By understanding regular patterns in network traffic and event logs, anomaly rules can highlight significant outliers that warrant further investigation.

Reference The functionality and configuration of anomaly rules are covered extensively in the IBM QRadar SIEM administration guide, providing administrators with the tools to effectively detect and respond to abnormal network activities.

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 : A

The primary method used by IBM QRadar SIEM V7.5 to alert users to problems is through System Notifications. Here's how it works:

System Notifications: These are alerts generated by QRadar to inform users of various issues, such as system performance problems, license issues, or security incidents.

Visibility: Notifications are prominently displayed in the QRadar GUI, ensuring that administrators and users can quickly identify and respond to any problems.

Customization: Users can configure notification settings to receive alerts for specific types of issues, ensuring they stay informed about critical aspects of the system's health and performance.

Reference IBM QRadar SIEM documentation outlines the use of System Notifications as the primary method for alerting users to issues, detailing how to configure and manage these alerts.

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

In IBM QRadar SIEM V7.5, managing what functions a user can access is crucial for maintaining security and ensuring that users have appropriate permissions. The Security Profile option is used to manage these access controls. Here's how it works:

Security Profile: Defines the specific permissions and roles assigned to users, dictating what actions they can perform within QRadar. This includes access to various modules, dashboards, and functionalities.

User Role: While related, user roles are more about grouping users with similar permissions rather than defining individual access.

Admin Role: Typically reserved for users with administrative privileges but does not manage the specific functions users can access.

Security Options: This is not a relevant option for managing user access to QRadar functions.

Reference IBM QRadar SIEM V7.5 documentation details how security profiles are configured and managed, providing comprehensive steps on assigning and modifying user access based on roles and profiles.

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 : B, C

To include geographic data updates from MaxMind in IBM QRadar SIEM V7.5, the following two pieces of information from the MaxMind account are required:

API Key: This key is used to authenticate and authorize access to the MaxMind services, ensuring that QRadar can request and receive geographic data updates.

License Key: This key is associated with the MaxMind account and allows QRadar to utilize the licensed geographic data for enhanced location-based analysis.

These keys ensure that the data integration is secure and that the usage complies with MaxMind's licensing agreements.

Reference IBM QRadar SIEM documentation specifies the API key and license key as necessary credentials for integrating MaxMind geographic data, detailed in the setup and configuration sections.
