Demo Questions
Question 1
Which command does an administrator run in QRadar to get a list of installed applications and their App-ID values output to the screen?
- opt/qradar/support/deployment_info.sh
- /opt/qradar/support/recon ps
- /opt/qradar/support/recon connect 1005
- /opt/qradar/support/threadTop.sh
Correct answer: A
Explanation:
To get a list of installed applications and their App-ID values in IBM QRadar SIEM, the administrator can run the following command:Command: /opt/qradar/support/deployment_info.shFunction: This command outputs detailed information about the current deployment, including a list of all installed applications and their associated App-ID values.Usage: The administrator executes this command in the terminal, and the information is displayed on the screen.Reference IBM QRadar SIEM V7.5 administration guides include this command as a standard tool for retrieving deployment information, including details about installed applications and their IDs.

Question 2
A user reports that some data points are missing from a generated report. The logs show these notifications, which are determined to be the root cause of the problem:
The accumulator was unable to aggregate all events/flows for this interval.
In what timeframe does this system need to complete data aggregation for it to be deemed successful?
- 30 seconds
- 5 seconds
- 120 seconds
- 60 seconds
Correct answer: D
Explanation:
In IBM QRadar SIEM V7.5, the accumulator process must complete data aggregation within a specific timeframe to be deemed successful:Timeframe: 60 secondsAggregation Process: The accumulator aggregates events and flows for reporting and analysis. If it cannot complete this task within 60 seconds, it is considered unsuccessful.Impact: Failure to aggregate within the specified timeframe can result in missing data points in reports and dashboards, affecting the accuracy and completeness of the information presented.Reference The QRadar SIEM administration guides detail the accumulator process and the importance of completing data aggregation within 60 seconds to ensure accurate reporting.

Question 3
What is the main reason for tuning a building block?
- Increasing the performance of the ecs-ec-ingress service
- Reducing the number of false positives
- Properly documenting the building block for future administrators
- Reducing EPS usage
Correct answer: 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 normaland 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.Improved Accuracy: Enhanced precision in detecting true security incidents, thus improving the overall effectiveness of the SIEM solution.Reference IBM QRadar SIEM administration guides and best practice documents emphasize the importance of tuning to minimize false positives, ensuring more actionable alerts.
