QUESTION: 25

When do you consider reconfiguring your QRadar environment to a distributed deployment?

When flow sources reach a threshold of 20 Mbps
When processing or storage expands beyond capacity on your single deployed appliance
When you need to upgrade the Log Source Manager application
When your combined log sources are less than 2000 events per second

Answer(s): B

Explanation:

Reconfiguring your IBM QRadar environment to a distributed deployment is considered under the following circumstances:

Capacity Limits: When the processing or storage requirements of your QRadar environment exceed the capacity of a single appliance, it becomes necessary to distribute the workload across multiple systems.

Performance Improvement: A distributed deployment allows for better load balancing and performance optimization by distributing event and flow processing tasks.

Scalability: As your organization's data volume grows, a distributed deployment ensures that QRadar can handle the increased load without degradation in performance.

Reference
IBM QRadar SIEM administration guides discuss the considerations and benefits of moving to a distributed deployment when scaling beyond the capacity of a single appliance.

QUESTION: 26

What is the REST API interface to install and manage applications that are created by using the GUI Application Framework Software Development Kit?

/api/gui_app_framework
/api/data_classification
/api/system
/api/siem

Answer(s): A

Explanation:

The primary method used by IBM QRadar to install and manage applications created using the GUI Application Framework Software Development Kit (SDK) is through the REST API interface:

API Endpoint: /api/gui_app_framework

Functionality: This endpoint allows administrators to manage the lifecycle of applications, including installation, updates, and removal.

Integration: Provides seamless integration with the GUI Application Framework, enabling the development and deployment of custom applications within QRadar.

Reference
The IBM QRadar API documentation provides details on the /api/gui_app_framework endpoint and its usage for managing GUI applications.

QUESTION: 27

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

Answer(s): 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 seconds

Aggregation 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: 28

You want to use a quick filter search to look for certain elements:

. 10.100.100.*

· BlueCoat

· TCP_REFRESH_MIS

Which string provides the correct results?

(10.100.100.- Bluecoat TCP_REFRESH_MIS)
10.100.100.*%Bluecoat%TCP_REFRESH_MIS
"10.100.100.*%AND%Bluecoat%AND%TCP_REFRESH_MIS"
(10.100.100/ AND Bluecoat AND TCP_REFRESH_MIS)

Answer(s): C

Explanation:

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.
