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

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 : 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 : 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 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

TACACS (Terminal Access Controller Access-Control System) authentication is a protocol used in IBM QRadar SIEM V7.5 for authenticating users by forwarding their credentials to an external server. Here's how it works:

Encryption: TACACS encrypts the entire payload of the authentication packet, including the username and password, ensuring secure transmission.

Forwarding Credentials: After encryption, the credentials are forwarded to an external TACACS server, which performs the actual authentication.

Authentication Process: The external server checks the credentials against its database and sends a response back to QRadar indicating whether the authentication is successful or not.

Reference IBM QRadar SIEM documentation explains TACACS authentication in detail, highlighting its secure encryption and external server verification process.

Answer : B

When configuring a log source in IBM QRadar SIEM V7.5, the protocols used to receive data into the event ingress component are critical for ensuring proper data collection and analysis. The main protocols that are supported for this purpose are:

Syslog: A widely used protocol for message logging, supported by many network devices and servers.

HTTP Receiver: Allows QRadar to receive logs via HTTP POST requests, enabling integration with various web services and applications.

SNMP (Simple Network Management Protocol): Used for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior.

Reference IBM QRadar SIEM documentation and product guides confirm that these are the supported protocols for receiving data into the event ingress component. The specific details on protocol support can be found in the QRadar SIEM administration and configuration manuals.

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.
