Question 1

Which is a valid routing rule combination?

Accepted Answer

C

Explanation: In IBM QRadar SIEM, routing rules determine how incoming events are processed before they are written to storage. A single routing rule can be configured with multiple actions. The combination of "Forward" and "Bypass Correlation" is valid. This configuration allows an event to be sent to an external destination (e.g., another SIEM or a data lake) while also being stored locally on QRadar for searching and reporting, but without being analyzed by the Custom Rules Engine (CRE). This is useful for managing system load or for events that are needed for archival but not for real-time threat detection.

Question 2

An administrator opens the Offenses section and goes to Rules to edit the system notification rule. What is the rule name for system notifications?

Accepted Answer

A

Explanation: In IBM QRadar SIEM, system health events are processed by a specific, predefined rule to generate alerts and offenses for administrators. The default rule responsible for this function is explicitly named "System: Notification". This rule is designed to monitor a wide range of internal system events, such as service failures, license limit warnings, deployment issues, and performance threshold breaches. When one of these events occurs, this rule triggers to create a notification, which typically manifests as an offense on the "Offenses" tab, ensuring that system health issues are promptly brought to the attention of the security team.

Question 3

When configuring a log source, which protocols are used when receiving data into the event ingress component?

Accepted Answer

B

Explanation: The IBM QRadar event ingress component, typically an Event Collector, receives data using various protocols. The most common listener-based, or "push," protocols are Syslog, SNMP, and HTTP Receiver. Syslog is a standard for forwarding log messages. SNMP (Simple Network Management Protocol) is used to receive trap messages from network devices. The HTTP Receiver protocol allows QRadar to act as a web server, collecting events sent via HTTP/S POST requests, which is common for cloud services and custom applications. These three protocols represent a core set of methods by which external sources actively send event data to be received by QRadar.

Question 4

Which two (2) data sources can be assigned to a domain in the Domain Management function?

Accepted Answer

C, D

Explanation: In IBM QRadar SIEM, the Domain Management feature is designed to segregate data, typically for multi-tenant or segmented network environments. This segregation is achieved by assigning specific data-generating assets to a defined domain. The primary sources of data that QRadar processes are events and flows. Therefore, log sources, which generate event data, and flow collectors, which process and generate flow data, are the fundamental objects that can be assigned to a domain to ensure that all data they produce is tagged and isolated within that domain.

Question 5

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

Accepted Answer

A

Explanation: IBM QRadar automatically assigns a default schedule to new weekly reports. According to the product documentation, weekly reports are queued to run at 01:00 AM every Sunday. Administrators may alter this schedule, but if no change is made the first run occurs at that default day/time. Therefore, the only option that matches the documented default is Sunday 01:00 AM (Option A).

Question 6

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

Accepted Answer

C

Explanation: When the rate of incoming events or flows exceeds the licensed Events Per Second (EPS) or Flows Per Minute (FPM) limit, IBM QRadar activates its burst handling mechanism. Instead of dropping the excess data immediately, it is placed into a temporary buffer or queue. QRadar continues to process data from the queue at the maximum licensed rate. This feature is designed to manage short-term spikes in data volume without data loss. A system notification is also generated to alert administrators that the license limit has been exceeded. If the high data rate persists and the queue fills to capacity, new events or flows will then be dropped.

Question 7

A ORadar administrator creates a new saved search in QRadar and wants to add the search to a
dashboard, but the option "Include in my Dashboard" cannot be selected.
What is a possible reason it is unavailable?

Accepted Answer

A

Explanation: To display saved search results as a graphical chart (e.g., bar, pie, time series) on a QRadar dashboard, the search query must contain a GROUP BY clause. If the search is not grouped, it can only be displayed as a list of results. The "Include in my Dashboard" option becomes available to create a chart-based dashboard item only when the search criteria include aggregation and grouping. While permission issues can also restrict dashboard modifications, the most direct and common reason related to the search criteria itself is the absence of a GROUP BY clause, which is a prerequisite for all graphical dashboard items.

Question 8

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

Accepted Answer

D

Explanation: IBM e-mail notification templates are XML fragments that contain a element (mail subject line) and one or more elements (body text). IBM guides state that when you tailor a template you insert or change your own wording, variables, or translations only in those two elements; other tags such as or are structural and normally left untouched. Therefore the two elements you edit to incorporate your customisations are and .

Question 9

A QRadar administrator creates a new saved search in QRadar. Which option does the administrator enable to allow this search to be opened as the Log Activity tab is opened?

Accepted Answer

A

Explanation: The "Set as Default" option is specifically designed to make a saved search the initial view that loads when a user opens the associated tab. When an administrator creates a search in the Log Activity tab and selects "Set as Default" upon saving, QRadar will automatically run that search and display its results every time the administrator opens the Log Activity tab. This overrides the default real-time streaming view, providing a customized initial perspective based on the saved search criteria.

Question 10

From which two (2) resources can an administrator download QRadar security content?

Accepted Answer

A, E

Explanation: IBM QRadar security content, which includes applications, content packs, and extensions, is distributed through two primary channels. The IBM Security App Exchange is the official web-based marketplace where administrators can browse and download content packages. Within the QRadar product itself, the QRadar Assistant App provides an integrated interface to connect to the QRadar Application Repository (which is populated by the App Exchange) to find, download, and install these same extensions directly onto the QRadar Console.

Question 11

The Report wizard provides a step-by-step guide to design, schedule, and generate reports. Which three (3) key elements does the report wizard use to help you create a report?

Accepted Answer

A, B, F

Explanation: The IBM QRadar Report wizard is a structured, step-by-step tool for report creation. The process is organized around three fundamental elements. First, the user defines the Layout, which includes selecting a template, page orientation, and branding elements like a logo. Second, the user specifies the Content by adding and configuring various containers for charts, tables, and event lists. Finally, the user chooses the output Format (such as PDF, HTML, or CSV) and sets up the distribution schedule. These three elements—Layout, Content, and Format—represent the core stages of the report design process within the wizard.

Question 12

What parameter contributes to the magnitude score of an offense?

Accepted Answer

D

Explanation: The magnitude of an offense in IBM QRadar is a calculated value from 0 to 10 that indicates its overall importance and helps prioritize security incidents. This score is determined by three primary parameters: Relevance, Severity, and Credibility. Credibility specifically measures the integrity and certainty of the offense. It is influenced by the reliability rating of the log source that reported the event and increases as multiple sources report the same event, indicating a higher likelihood that the attack is real and not a false positive.

Question 13

In the QRadar GUI. you notice that no new offenses were generated today. A review of the
notifications shows:
MPC: Unable to create new offense. The maximum number of active offenses has been reached.
What is the default value of the maximum number?

Accepted Answer

D

Explanation: The notification "MPC: Unable to create new offense. The maximum number of active offenses has been reached" is generated by the Magistrate Processing Component (MPC) in QRadar. This occurs when the number of open, active offenses meets a predefined system limit, which is designed to maintain system performance. The default value for this limit is 2,500 active offenses. When this threshold is reached, QRadar stops creating new offenses until existing ones are closed or the limit is increased by an administrator. This setting is controlled by the OFFENSECREATIONMAXACTIVEOFFENSES parameter in the nva.conf file.

Question 14

In which QRadar section can the administrator view the license giveback rate?

Accepted Answer

C

Explanation: The License Pool Management section in the QRadar Admin tab is the designated interface for managing and monitoring license allocations across all hosts in a deployment. This screen provides a comprehensive table view of each host's license capacity, current usage, and other key metrics. The "License Giveback" rate, which indicates the amount of unused license capacity a host is returning to the shared pool, is explicitly displayed as a column in this table for each applicable host.

Question 15

A QRadar administrator needs to quickly check the disk space for all managed hosts. Which command does the administrator use?

Accepted Answer

C

Explanation: The /opt/qradar/support/allservers.sh script is a utility used to execute a command on all managed hosts within an IBM QRadar deployment from the console. To check disk space, the standard Linux command is df. The -T flag displays the file system type, and the -h flag presents the sizes in a human-readable format (e.g., KB, MB, GB). Therefore, executing df -Th via the allservers.sh script is the correct and most efficient method to check the disk space for all managed hosts simultaneously.
