Question 1

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 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?

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 3

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 4

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 5

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 6

When creating an identity exclusion search, what time range do you select?

APrevious 7 days

BReal time (streaming)

CPrevious 30 days

DPrevious 5 minutes

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.

Question 7

What is the default day and time setting for when QRadar generates weekly reports?

ASunday 01:00 AM

BMonday 02:00 AM

CSunday 02:00 AM

DMonday 01:00 AM

Answer : A

In IBM QRadar SIEM V7.5, the default setting for generating weekly reports is configured to occur on:

Day: Sunday

This setting ensures that the reports are generated during a typical low-activity period, minimizing the impact on system performance and ensuring that the latest data from the previous week is included.

Reference The default configuration for report generation times is specified in the IBM QRadar SIEM V7.5 administration and user documentation.
