NEW QUESTION # 76
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?
- A. High Level Category Unknown Events
- B. Low Level Category: Stored Events
- C. Log Only Events sent to a Data Store
- D. High Level Category: User Defined Events
- E. Forwarded Events to different destination
Answer: A,C
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.
NEW QUESTION # 77
Which two (2) of these elements can be used by the Report wizard to design a report?
- A. Assets
- B. Layout
- C. Content
- D. Traffic
- E. Network
Answer: B,C
Explanation:
In the QRadar Report wizard, elements such as "Content" (D) and "Layout" (E) are crucial for designing a report. The "Content" element pertains to the specific data, charts, and information that will be included in the report, defining what insights the report will provide. The "Layout" element involves the organization and presentation of this content within the report, including the structure and visual aspects that determine how the information is displayed to the user. Together, these elements allow for the customization and creation of reports that meet specific informational and aesthetic requirements, making them essential components of the Report wizard in QRadar .
NEW QUESTION # 78
Which two (2) aggregation types are available for the pie chart in the Pulse app?
- A. Average
- B. Total
- C. First
- D. Middle
- E. Last
Answer: B,C
Explanation:
* Pie Chart Logic: Pie charts represent proportions of a whole.expand_more QRadar Pulse supports the following aggregations suitable for this:
* Total (Sum): Calculates the sum of a selected field's values, displaying each slice relative to the whole.
* First: Takes the first value encountered in a field, useful for categorical data to show initial distribution.
NEW QUESTION # 79
In QRadar. what are building blocks?
- A. A collection of tests that don't result in a response or an action
- B. A network hierarchy node
- C. An entry in the reference set named "System Entries"
- D. A rule under the rule group "System"
Answer: A
Explanation:
Building Blocks in QRadar are foundational elements that are used to construct more complex rules. They are essentially a collection of conditional tests or criteria that define specific behaviors, characteristics, or patterns within the network data but do not, by themselves, trigger any responses or actions when those conditions are met.
Building Blocks are designed to be reused in multiple rules, making rule creation more efficient and standardized. For example, a Building Block might define a set of commonmalicious IP addresses or unusual traffic patterns. This Building Block can then be incorporated into several different rules that might deal with various types of threats, each of which requires identifying traffic from or to these malicious IPs as part of their logic.
The reusability of Building Blocks ensures that changes to common criteria, such as updating the list of malicious IP addresses, only need to be made in one place. This approach enhances the maintainability and consistency of the rule set within QRadar, making the system more agile and responsive to changes in the threat landscape.
Building Blocks are a powerful feature within QRadar that promote modularity and efficiency in rule creation, helping organizations tailor their threat detection capabilities to their specific needs without requiring actions or responses to be defined within these foundational elements themselves.

On the Offenses tab, which column explains the cause of the offense?
- A. Offense Type
- B. Description
- C. IPs
- D. Magnitude
Answer: A
Explanation:
On the Offenses tab within QRadar, the "Offense Type" column explains the cause of the offense. The offense type is determined by the rule that triggered the offense, and it dictates the kind of information displayed in the Offense Source Summary pane. This helps analysts understand the nature and origin of the offense, facilitating more effective investigation and response actions.

NEW QUESTION # 88
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 as well as the report template are deleted.
- B. All reports that were generated from the report template are deleted, but the report template is retained.
- C. All reports that were generated from the report template as well as the report template are deleted.
- D. Only specific reports that were not generated from the report template are deleted, but the report template is retained.
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 # 89
What does this example of a YARA rule represent?
- A. Flags containing hex sequence and str1 less than three times
- B. Flags content that contains the hex sequence, and str1 greater than three times
- C. Flags for str1 at an offset of 25 bytes into the file
- D. Flags content that contains the hex sequence, and hex! at least three times
Answer: C
Explanation:
A YARA rule is used for malware identification and classification, based on textual or binary patterns. The example provided suggests a rule that flags occurrences of a specific string (str1) at a precise location within a file. The "offset" keyword in YARA rules specifies the exact byte position where the pattern (in this case,
'str1') should appear. Thus, the correct interpretation of the YARA rule example is that it flags instances where
'str1' appears 25 bytes into the file,indicating a very specific pattern match used for identifying potentially malicious files or activities that conform to this pattern.
NEW QUESTION # 90
An analyst must create a reference set collection containing the IPv6 addresses of command-and-control servers in an IBM X-Force Exchange collection in order to write a rule to detect any enterprise traffic with those malicious IP addresses.
What value type should the analyst select for the reference set?
- A. IPv6
- B. IP
- C. IPv4 or IPv6
- D. AlphaNumeric (Ignore Case)
Answer: A
Explanation:
* Specificity: The question states that the addresses are specifically IPv6-formatted. Using the 'IPv6' type ensures precision in the reference set.
* IP Matching by QRadar: QRadar's rule engine will properly match against IPv6 addresses when the reference set type is 'IPv6'.
NEW QUESTION # 91
How can an analyst identify the top rules that generated offenses in the previous week and were closed as false positives or tuned?
- A. Use Case Manager app > CRE Report > Filter Offenses with the following direction > R2R > Select False-Positive, Tuned.
- B. From Reports > CRE Report > Weekly reports > False positives reports
- C. From Reports > Offenses Report > Weekly reports > False positives reports
- D. Use Case Manager app > Active Rules > Filter Offenses with start date > Closure Reason > Select False-Positive, Tuned
Answer: D
Explanation:
* Use Case Manager: This app is specifically designed for investigation and analysis of offenses within QRadar. It offers more focused tools for this task than general Reports.
* Active Rules: This view within the Use Case Manager provides insights into rules that directly triggered offenses. This is essential for filtering down to our target rules.
* Filtering:
* Start Date: Allows you to limit the analysis timeframe to the "previous week" as specified in the question.
* Closure Reason: Crucially, this lets you isolate offenses marked as "False Positive" or "Tuned" - the core of the question.
NEW QUESTION # 92
What is the difference between an unknown event and a stored event?
- A. Stored events are mapped to the proper log source. Unknown events are collected and parsed.
- B. Unknown events are collected and parsed, but cannot be mapped or categorized to a specific log source and stored events cannot be understood or parsed by QRadar.
- C. Stored events are collected and parsed but cannot be mapped or categorized to a specific log source.
Unknown events cannot be understood or parsed by QRadar. - D. Unknown events are mapped to the proper log source. Stored events are collected and parsed.
Answer: B
Explanation:
In QRadar, "unknown events" refer to data that is collected and parsed by the system but cannot be accurately mapped or categorized to a specific log source due to lack of sufficient information or matching criteria. On the other hand, "stored events" imply that the data has been retained in the system but may not be fully understood or parsed by QRadar, possibly due to it not conforming to expected formats or lacking recognizable patterns. This distinction highlights the challenges in data categorization and analysis within a SIEM system, where not all collected data can be immediately attributed to known sources or fully analyzed due to various constraints .
NEW QUESTION # 93
The magnitude rating of an offense in QRadar is calculated based on which values?
- A. Relevance, credibility, severity
- B. Relevance, severity, importance
- C. Criticality, severity, credibility
- D. Criticality, severity, importance
Answer: A
Explanation:
The magnitude rating of an offense in QRadar is calculated based on relevance, severity, and credibility. Relevance determines the impact on the network, credibility indicates the integrity of the offense, and severity represents the level of threat. QRadar uses complex algorithms to calculate and periodically re-evaluate the offense magnitude rating.
NEW QUESTION # 94
Which type of rule requires a saved search that must be grouped around a common parameter
- A. Anomaly Rule
- B. Flow Rule
- C. Common Rule
- D. Event Rule
Answer: D
NEW QUESTION # 95
