NEW QUESTION # 16
A QRadar analyst is using the Log Activity screen to investigate the events that triggered an offense.
How can the analyst differentiate events that are associated with an offense?
- A. Fully matched events are not indexed
- B. Separate columns named 'Paritally matched' and 'Fully matched' are populated
- C. A red star icon in the first column of event list indicates a fully-matched event
- D. Partially matched events are not indexed
Answer: C
Explanation:
* QRadar uses a red star icon to visually identify events that directly contributed to triggering an offense.
These events fully matched all the criteria specified in the rule that generated the offense.
* Partially matched events may also be associated with the offense (especially for rules using match counts), but they won't have the red star. These events are still valuable for providing context during investigations.

NEW QUESTION # 20
How can adding indexed properties to QRadar improve the efficiency of searches?
- A. By increasing the size of the data set required to find non-indexed search values
- B. By slowing down the search process
- C. By reducing the size of the data set required to find non-indexed search values
- D. By reducing the number of indexed search values
Answer: C
Explanation:
Adding indexed properties to QRadar can significantly improve the efficiency of searches by reducing the size of the data set required to locate matches for non-indexed search values. Indexing creates references to unique terms in the data and their locations, which means that the search engine can filter the data set by indexed properties first, eliminating irrelevant portions of the data set and thereby reducing the overall volume of data that needs to be searched.

What happens when you select "False Positive" from the right-click menu in the Log Activity tab?
- A. You can tune out events that are known to be false positives.
- B. Items are filtered that match or do not match the selection.
- C. You can investigate an IP address or a user name.
- D. The selected event is filtered based on the selected parameter in the event.
Answer: A
Explanation:
Selecting "False Positive" from the right-click menu in the Log Activity tab opens a window that enables users to tune out events that are known to be false positives, preventing them from generating offenses. This feature is crucial for minimizing noise and focusing on genuine threats, thereby enhancing the efficiency of threat detection and response processes within QRadar.
NEW QUESTION # 24
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?
- A. Host definitions
- B. Host reference
- C. Behavior definition
- D. Device definition
Answer: A
Explanation:
* 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.
NEW QUESTION # 25
Which two (2) types of categories comprise events?
- A. Parsed
- B. Stored
- C. Found
- D. Unsupported
- E. Unfound
Answer: A,B
Explanation:
While the documentation does not explicitly list "Stored" and "Parsed" as categories comprising events, it discusses high-level event categories and the process of categorizing incoming events for easy searching. Without specific mention of the categories "Stored" and "Parsed," the provided documentation does not verify any of the options directly. Further insight into event categories is provided by discussing how events are grouped into high-level categories for organizational purposes.
NEW QUESTION # 26
In QRadar. what do event rules test against?
- A. Event and flow data
- B. The parameters of an offense to trigger more responses
- C. Incoming flow data that is processed by the QRadar Flow Processor
- D. Incoming log source data that is processed in real time by the QRadar Event Processor
Answer: D
Explanation:
Event rules in QRadar test against incoming log source data processed in real time by the QRadar Event Processor. This real-time processing enables QRadar to analyze and respond to security events as they occur, enhancing the system's ability to detect and mitigate threats promptly.
NEW QUESTION # 27
Offense chaining is based on which field that is specified in the rule?
- A. Offense response field
- B. Rule response field
- C. Rule action field
- D. 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.
NEW QUESTION # 28
Which of these statements regarding the deletion of a generated content report is true?
- A. Only specific reports that were not generated from the report template are deleted, but the report template is retained.
- B. All reports that were generated from the report template are deleted, but the report template is retained.
- C. Only specific reports that were not generated from the report template as well as the report template are deleted.
- D. All reports that were generated from the report template as well as the report template are deleted.
Answer: B
Explanation:
When deleting a generated content report in QRadar, all reports that were generated from the report template are deleted, but the report template itself is retained. This ensures that the structure for generating future reports remains intact, while only the instances of reports generated from that template are removed.
NEW QUESTION # 29
To verify whether the login ID that was used to log in to QRadar is assigned to a user, create a list with the LoginlD parameter.
This example refers to what kind of reference data collections?
- A. Reference login
- B. Reference set
- C. Reference map
- D. Reference map of maps
Answer: C
Explanation:
* Understanding Login ID Verification: Verifying whether a login ID is assigned to a user involves checking a mapping of login IDs to user records. This process requires a data structure that can map unique login IDs to user information.
* Suitable Reference Data Collection:
* Reference Map of Maps: Used for storing nested key-value pairs but more complex than needed for simple login ID verification.
* Reference Login: Not a standard reference data collection in QRadar.
* Reference Map: Ideal for mapping login IDs (unique keys) to user details (values).
* Reference Set: Stores unique values but does not map them to any associated data.
* Using Reference Map: The reference map is the appropriate choice as it allows for direct mapping of each login ID to corresponding user details. This structure facilitates efficient verification processes.
* Reference Confirmation: According to IBM QRadar documentation, using a reference map to associate login IDs with user details is a standard approach for verifying user assignments.
References:
* IBM QRadar documentation on reference data collections indicates the use of reference maps for
* mapping unique identifiers like login IDs to user records.
NEW QUESTION # 30
After how much time will QRadar mark an Event offense dormant if no new events or flows occur?
- A. 5 minutes
- B. 30 minutes
- C. 24 hours
- D. 2 hours
Answer: B
Explanation:
QRadar will mark an Event offense as dormant if no new events or flows occur within 30 minutes. However, if QRadar did not process any events within 4 hours, this also triggers the offense to become dormant. Once dormant, the offense remains in this state for 5 days unless new events or flows are added.
