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 : A

In IBM QRadar SIEM V7.5, events or flows stop contributing to an offense when the offense becomes dormant. Here's how it works:

Dormant Offense: An offense becomes dormant when there is no new activity contributing to it for a specified period. This indicates that the threat or incident has not had any further related events or flows.

Contribution Stoppage: Once an offense is marked as dormant, no additional events or flows are added to it, which helps in managing the offense lifecycle and resources within QRadar.

This behavior helps in distinguishing between active and inactive threats, allowing security analysts to focus on ongoing incidents.

Reference The QRadar SIEM administration and user guides provide detailed explanations of offense management, including the conditions under which offenses become dormant and how this affects event and flow contributions.

Answer : D

The Server Discovery function in IBM QRadar SIEM V7.5 uses the Asset Profile Database to discover various types of servers on a network. This database stores detailed information about the assets, including server types, configurations, and roles within the network. Here's how it works:

Asset Profile Database: This is the central repository that contains all the discovered asset information.

Discovery Process: During the discovery process, QRadar scans the network to identify servers and other devices, collecting information such as IP addresses, open ports, services, and operating systems.

Classification: The collected data is then analyzed and classified, updating the Asset Profile Database with the types of servers discovered.

Reference IBM QRadar SIEM documentation specifies the use of the Asset Profile Database for server discovery functionalities and provides details on configuring and managing asset profiles.

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 : 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.
