Question 1

An administrator wants to export a list of events to a CSV file. Which items are in the default columns of the search result?

ALog Source. Event Count. High Level Category. Related Offense

BEvent Name. Application, Username, Log Source

CUsername. Source Port. Event Count, Magnitude

DProtocol. Storage Time, Destination Port, Source Port

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.

Question 2

When adjusting a custom email template, which two elements do you edit to include the customizations?

A<heading> <text>

B<heading> <body>

C<subject> <text>

D<subject> <body>

Answer : D

When adjusting a custom email template in IBM QRadar SIEM V7.5, the two elements that need to be edited to include customizations are:

<subject>: This element defines the subject line of the email, which can be customized to provide a clear and relevant description of the email's content.

<body>: This element contains the main content of the email. Customizing the body allows administrators to include specific information, formatting, and messages relevant to the recipient.

Customizing these elements ensures that the email notifications are informative and tailored to the needs of the recipients.

Reference The QRadar SIEM user and configuration guides provide instructions on customizing email templates, highlighting the <subject> and <body> elements as key areas for customization.

Question 3

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?

A30 seconds

B5 seconds

C120 seconds

D60 seconds

Answer : D

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 4

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

A/api/gui_app_framework

B/api/data_classification

C/api/system

D/api/siem

Answer : A

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 5

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

AWhen flow sources reach a threshold of 20 Mbps

BWhen processing or storage expands beyond capacity on your single deployed appliance

CWhen you need to upgrade the Log Source Manager application

DWhen your combined log sources are less than 2000 events per second

Answer : B

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 6

What occurs when QRadar reaches the events per second (EPS) or flows per minute (FPM) shared license pool limits?

AIncremental Licensing removes the limits on EPS and FPM.

BQRadar generates a notification that the limit was reached and stops processing.

CData accumulates in a temporary burst handing queue, but QRadar continues to process events and flows.

DEvents and flows continue to process, and the Network and Log Activity tabs remain active.

Answer : C

When IBM QRadar SIEM V7.5 reaches the events per second (EPS) or flows per minute (FPM) shared license pool limits, the following occurs:

Burst Handling Queue: QRadar utilizes a temporary burst handling queue to manage the overflow of events and flows. This queue temporarily holds data until the system can process it.

Continued Processing: QRadar continues to process events and flows despite reaching the license limits, ensuring no data is lost.

Efficiency: This mechanism allows QRadar to handle short-term spikes in data volume without compromising the integrity or continuity of event and flow processing.

Reference The handling of EPS and FPM limits is described in IBM QRadar SIEM's system administration and configuration guides, which explain how QRadar manages data when license thresholds are exceeded.

Question 7

What is the primary method used by QRadar to alert users to problems?

ASystem Notifications

BSystem Summary

CUse Case Manager

DQRadar Assistant

Answer : A

The primary method used by IBM QRadar SIEM V7.5 to alert users to problems is through System Notifications. Here's how it works:

System Notifications: These are alerts generated by QRadar to inform users of various issues, such as system performance problems, license issues, or security incidents.

Visibility: Notifications are prominently displayed in the QRadar GUI, ensuring that administrators and users can quickly identify and respond to any problems.

Customization: Users can configure notification settings to receive alerts for specific types of issues, ensuring they stay informed about critical aspects of the system's health and performance.

Reference IBM QRadar SIEM documentation outlines the use of System Notifications as the primary method for alerting users to issues, detailing how to configure and manage these alerts.
