In a single domain QRadar deployment, which IP addresses are considered local?
- A . Any private IP address
- B . Any public IP address
- C . Any IP address that is defined in the network hierarchy
- D . Any IP address that is not defined in the network hierarchy
C
Explanation:
In a single domain QRadar deployment, the IP addresses considered local are those that are defined in the network hierarchy. Here is a detailed explanation:
Network Hierarchy: QRadar uses a network hierarchy to define and manage IP addresses within the organization. This hierarchy allows QRadar to understand which IP addresses are part of the internal network and which are external.
Defining Local IP Addresses: Any IP address that is specified within the network hierarchy is considered local. This includes all the subnets and IP ranges that are part of the internal network.
Purpose: By defining the network hierarchy, QRadar can effectively differentiate between internal (local) and external (non-local) traffic, enabling more accurate detection and correlation of security events.
This approach helps in identifying suspicious activities by comparing the source and destination of traffic against the defined internal network.

Which is a valid routing rule combination?
- A . Drop and Bypass Correlation
- B . Drop and Log Only
- C . Forward and Bypass Correlation
- D . Bypass Correlation and Log Only
C
Explanation:
Forward: Data is forwarded to a specified destination. It is also stored in the database and processed by the Custom Rules Engine (CRE).
Drop: Data is dropped, meaning it is not stored in the database and is not processed by the CRE. If you select the “Drop” option, any events that match this rule are credited back 100% to the license.
Bypass Correlation: Data bypasses the CRE but is stored in the database. This option allows events to be used in analytic apps and for historical correlation runs. It’s useful when you want specific events to skip real-time rules.
Log Only (Exclude Analytics): Events are stored in the database and flagged as “Log Only.” They bypass the CRE and are not available for historical correlation. These events contribute to neither offenses nor real-time analytics.
Now, let’s look at the valid combinations:
Forward and Drop: Data is forwarded to a specified destination, but it is not stored in the database or processed by the CRE. Dropped events are credited back to the license.
Forward and Bypass Correlation: Data is forwarded to a destination and stored in the database, but CRE rules do not run on it. Useful for scenarios where you want events to bypass real-time rules but still be available for historical correlation.
Forward and Log Only (Exclude Analytics): Events are forwarded to a destination, stored as “Log Only,” and bypass the CRE. They are not available for historical correlation and are credited back to the license.
In which QRadar section can the administrator view the license giveback rate?
- A . Admin tab > system settings
- B . Log Activity tab > AQL query in the Advanced Search "select LicenseGiveback from license"
- C . Admin tab > License pool management
- D . Log Activity tab by searching for the term "giveback" in the Quick Filter
C
Explanation:
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.
Which profile database does the Server Discovery function use to discover several types of servers on a network?
- A . Flow profile database
- B . Network profile database
- C . Domain profile database
- D . Asset profile database
D
Explanation:
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.
When restoring backups of your apps in a QRadar environment, what information is restored?
- A . The last known good version of your apps configuration, your application data, and any apps that were configured on an App Host are restored.
- B . The applications that are installed on the Console are restored, and any applications that are installed on an AppHost must be backed up separately.
- C . The apps configuration, the console configuration, and app data are restored.
- D . The apps configuration and app data are restored.
A
Explanation:
When restoring backups of your apps in a QRadar environment, the system restores the last known good version of your apps’ configuration, your application data, and any apps that were configured on an App Host. This comprehensive restoration process ensures that all critical components of your applications, including their configurations and data, are recovered to their previous states. This is crucial for maintaining the integrity and functionality of the applications after a restoration.

What is the main reason for tuning a building block?
- A . Increasing the performance of the ecs-ec-ingress service
- B . Reducing the number of false positives
- C . Properly documenting the building block for future administrators
- D . Reducing EPS usage
B
Explanation:
Tuning a building block in IBM QRadar SIEM V7.5 is primarily aimed at reducing the number of false positives. This process involves adjusting the rules and logic within the building block to better differentiate between normal and suspicious activity.
Here’s the detailed explanation:
False Positives: High numbers of false positives can overwhelm analysts and obscure genuine threats.
Tuning helps in refining detection criteria to reduce these false alarms.
Rule Adjustments: Modifying the thresholds, conditions, and filters within the building block rules to ensure they more accurately reflect the environment’s typical behavior.
