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 : B

When creating an identity exclusion search in IBM QRadar SIEM V7.5, the time range selected is 'Real time (streaming).' This setting ensures that the search continuously monitors and excludes identities in real-time as data is ingested. Here's the process:

Real-time Monitoring: Continuously updates the search results based on incoming data, providing immediate exclusion of specified identities.

Streaming Data: Processes data in a live stream, ensuring that the exclusion criteria are applied instantaneously as new events occur.

Reference The setup and configuration of identity exclusion searches are detailed in the QRadar SIEM administration guides, highlighting the importance of real-time streaming for effective identity management.

Answer : A

When exporting a list of events to a CSV file in IBM QRadar SIEM V7.5, the default columns included in the search result typically are:

Log Source: The origin of the log data.

Event Count: The number of events.

High Level Category: The broad classification of the event.

Related Offense: The associated offense ID or description.

These columns provide a comprehensive overview of the events, helping analysts quickly understand the context and significance of the data.

Reference IBM QRadar SIEM documentation provides details on the default columns included in search results and their significance in event analysis.

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 : 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.
