Question #:1
Offense chaining is based on which field that is specified in the rule?
Rule action field
Offense response field
Rule response field
Offense index field
Answer: D
Explanation
Offense chaining in IBM Security QRadar SIEM V7.5 is based on the offense index field specified in the rule.
This means that if a rule is configured to use a specific field, such as the source IP address, as the offense
index field, there will only be one offense for that specific source IP address while the offense is active. This
mechanism is crucial for tracking and managing offenses efficiently within the system.
Question #:2
What Is the result of the following AQL statement?
Returns all fields where the username contains the ERS string and is case-sensitive
Returns all fields where the username contains the ERS string and is case-insensitive
Returns all fields where the username is different from the ERS string and is case-insensitive
Returns all fields where the username is different from the ERS string and is case-sensitive
Answer: B
Explanation
The AQL (Ariel Query Language) statement provided would return all fields from the 'events' table where the
'username' column contains the string 'ERS', regardless of case. The 'ILIKE' operator in AQL is used for
case-insensitive pattern matching, which means that it will match 'ers', 'Ers', 'ErS', etc.

Raw event or flow data
Flow or parsing data
Raw event or processed data
Flow or processed data
Answer: A
Explanation
A Quick filter search in IBM Security QRadar SIEM operates on raw event or flow data. This type of search
allows users to rapidly filter through large volumes of data to find specific events or flows of interest without
the need for complex query syntax. Quick filter searches are particularly useful for conducting initial analyses
or when looking for specific indicators within the raw data streams. The ability to search directly on raw event
or flow data enables analysts to work with the most granular level of information available, facilitating
detailed investigations and the identification of subtle patterns or anomalies that might indicate security issues
.
Question #:4
Many offenses are generated and an analyst confirms that they match some kind of vulnerability scanning.
Which building block group needs to be updated to include the source IP of the vulnerability assessment (VA)
scanner to reduce the number of offenses that are being generated?
Host reference
Host definitions
Behavior definition
Device definition
Answer: B
Vulnerability Scans and Offenses: VA scanners frequently trigger alerts as their activity can resemble
malicious behavior.
Host Definitions: This QRadar building block group helps define known hosts, including their
attributes and roles on the network.
Adding to Definitions: Including the VA scanner's IP in the host definitions allows QRadar to
recognize it and properly categorize its activity.
Question #:5
Which condition is required to display the "Include in my Dashboard" parameter in the Log Activity tab while
saving a search?

Filter the columns that are listed in the Available Columns list and disable the Enable Unique Counts to
display the flow counts instead of average counts over Real Time
This parameter is only displayed if the search is grouped
The search must be set to Advanced Search and must be propagated with a high level of confidence
The result limits cannot be empty and not in a group
Answer: D
Question #:6
How does a Device Support Module (DSM) function?
A DSM is a configuration file that combines received events from multiple log sources and displays
them as offenses in QRadar.
A DSM is a background service running on the QRadar appliance that reaches out to devices deployed
in a network for configuration data.
A DSM is a configuration file that parses received events from multiple log sources and converts them
to a standard taxonomy format that can be displayed as outputs.
A DSM is an installed appliance that parses received events from multiple log sources and converts
them to a standard taxonomy format that can be displayed as outputs.
Answer: D
Question #:7
A task is set up to identify events that were missed by the Custom Rule Engine. Which two (2) types of events
does an analyst look for?
Log Only Events sent to a Data Store
High Level Category: User Defined Events
Forwarded Events to different destination
High Level Category Unknown Events
Low Level Category: Stored Events
Answer: A D

Explanation
To identify events that were missed by the Custom Rule Engine (CRE) in IBM Security QRadar SIEM, an
analyst would primarily look for "Log Only Events sent to a Data Store" and "High Level Category Unknown
Events." Log Only Events are those that are stored directly without being processed by the CRE, indicating
they might have been overlooked or not matched by any existing rules. High Level Category Unknown Events
are those that do not fit into any of the predefined categories in QRadar, suggesting that the CRE might not
have rules to handle or categorize these events properly. These types of events are crucial for analysts to
review to ensure that no significant incidents are missed and to refine the rule set for better detection in the
future.
Question #:8
Which parameter is calculated based on the relevance, severity, and credibility of an offense?
Magnitude rating
Severity age
Impact rating
Answer: A
Explanation
Understanding Offense Parameters in QRadar: In IBM QRadar, offenses are evaluated and
prioritized based on several parameters that determine the significance and potential impact of the
security incident.
Key Parameters:
Relevance: Indicates how relevant the event is to the organization's environment.
Severity: Represents the potential damage or impact the event could have on the system.
Credibility: Reflects the likelihood that the event represents a true security incident.
Magnitude Rating Calculation: The magnitude rating is a composite score that is calculated using the
relevance, severity, and credibility of an offense. This rating helps security analysts prioritize incidents
based on their potential threat level.
Reference Confirmation: According to IBM QRadar documentation, the magnitude rating is the
parameter that is derived from the relevance, severity, and credibility of an offense.

magnitude rating based on relevance, severity, and credibility .

Question #:9
Which two (2) options are used to search offense data on the By Networks page?
Raw/Flows
Events/Flows
NetIP
Severity
Network
Answer: B E
Explanation
To search offense data on the By Networks page, an analyst can use the options "Events/Flows" to filter based
on the types of data points, and "Network" to specify the network they want to search for. This allows for a
focused search on specific networks and types of data.
Question #:10
During an active offense review, an analyst observed that a single source system generated a significant
amount of high-rate traffic for transferring ^bound mail via port 25. The system responsible for this traffic was
not authorized to function as a mail server.
lat is the correct action in this situation?
Add the IP address of the source system to the Host Definition Mail Servers building block.
Continue to investigate the offense and follow the organization’s response processes to stop the source
system’s traffic.
Submit a request to the firewall team to allow this type of traffic from the source system to remote
destinations.
Use the False Positive Wizard to tune the specific event and event category.
Answer: B
Explanation
Understanding the Scenario: The detection of unauthorized high-rate traffic for transferring outbound
mail via port 25 indicates potential misuse or compromise of the source system.
Appropriate Response:
Investigate the Offense: The first step is to continue investigating the offense to gather more

details about the source system and the nature of the traffic.
Organizational Response Processes: Following the organization’s established response
processes ensures that appropriate actions are taken to mitigate the threat, which may include
blocking the traffic, isolating the system, or further forensic analysis.
Avoiding Incorrect Actions:
Adding to Building Blocks: Adding the IP address to the Host Definition Mail Servers building
block would incorrectly categorize the unauthorized system as a legitimate mail server.
Allowing Traffic: Submitting a request to the firewall team to allow this traffic would permit
unauthorized activity and potentially exacerbate the security issue.
False Positive Wizard: Using the False Positive Wizard is not suitable as this situation represents
a genuine security concern rather than a false positive.
Reference Confirmation: According to IBM QRadar documentation, the recommended action in such
scenarios is to follow the organization’s incident response processes to ensure a thorough and effective
response.
