Question #31
What parameter contributes to the magnitude score of an offense?
- A . Confidentiality
- B . Availability
- C . Integrity
- D . Credibility
Correct Answer: D
D
Explanation:
In IBM QRadar, the magnitude score of an offense is influenced by several parameters, one of which is credibility. Here’s a detailed explanation:
Magnitude Score: The magnitude score represents the severity and importance of an offense in QRadar. It is a composite score that helps prioritize incidents for investigation.
Credibility Parameter: Credibility assesses the reliability of the event source and the likelihood that the event represents a real threat. Higher credibility indicates that the source is reliable and the threat is more likely to be legitimate.
Contribution to Magnitude: The credibility parameter directly influences the magnitude score by weighting the offense higher if the credibility of the event is high. This ensures that more reliable and potentially more severe incidents are prioritized.
Credibility is one of the key factors used by QRadar to assess and prioritize security incidents, ensuring effective incident management.

Question #32
What is the most restrictive permissions a user needs in order to see all of the events from a particular log source in the Log Activity tab?
- A . The user needs access to the Networks AND Log Sources to see a particular log in the activity tab.
- B . The user’s security profile must include that log source, and the profile needs permission to Networks AND Log Sources.
- C . A user needs access to Flow Sources Only.
- D . The log source must be included in the user’s security profile and the profile needs its precedence set to Log Sources Only.
Correct Answer: B
B
Explanation:
To see all of the events from a particular log source in the Log Activity tab, a user must have the appropriate permissions set in their security profile.
The most restrictive permissions needed are:
Security Profile Inclusion: The log source must be included in the user’s security profile. This means the user must have explicit permission to access events from this log source.
Permissions to Networks and Log Sources: The user’s security profile must also include permissions to both Networks and Log Sources. This ensures the user has the necessary access to view events related to the specified log source within the network context.
These permissions are crucial to control and restrict access, ensuring users can only view data they are authorized to see while maintaining security and privacy within the system.

Correct Answer: A
Question #34
How can an administrator configure a rule response to add event data to a reference set?
- A . Write a custom script.
- B . Use AQL functions.
- C . Use the "add the following data to a reference set" rule test.
- D . Use the "add to reference set" rule response.
Correct Answer: D
D
Explanation:
Administrators can configure a rule response in QRadar to add event data to a reference set by using the "add to reference set" rule response. This is a predefined response action in QRadar that allows specific event data to be added to a reference set when the rule conditions are met.
Navigate to the "Offenses" tab in the QRadar console.
Select "Rules" from the navigation pane.
Create a new rule or edit an existing rule.
In the "Rule Response" section, add a new response.
Select the "Add to Reference Set" response.
Specify the reference set and the data to be added.
Save and deploy the rule.

Question #36
What is the Advanced Search field used for?
- A . Running an Acceptable Query Language search
- B . Running an Advanced Query Language search
- C . Running an ArangoDB Query Language search
- D . Running an Ariel Query Language search
Correct Answer: D
D
Explanation:
The Advanced Search field in IBM QRadar is used for running Ariel Query Language (AQL) searches.
Here’s a detailed explanation:
Ariel Query Language (AQL): AQL is a query language used in QRadar to search and retrieve event and flow data from the Ariel database. It is similar to SQL but tailored for the specific needs of QRadar’s data structure.
Advanced Search Field: The advanced search field provides a user interface for crafting and executing AQL queries. This allows users to perform detailed and complex searches to analyze specific patterns, behaviors, or events in their security data.
Functionality: Using AQL, users can specify criteria for selecting and filtering data, allowing for precise and comprehensive searches. This is essential for deep-dive investigations and custom reports.
The ability to run AQL searches gives analysts powerful tools to extract meaningful insights from their security data.

Question #38
You want to use a quick filter search to look for certain elements:
• 10.100.100.*
• BlueCoat
• TCP_REFRESH_MIS
Which string provides the correct results?
- A . (10.100.100.- Bluecoat TCP_REFRESH_MIS)
- B . 10.100.100.*%Bluecoat%TCP_REFRESH_MIS
- C . "10.100.100.*%AND%Bluecoat%AND%TCP_REFRESH_MIS"
- D . (10.100.100/ AND Bluecoat AND TCP_REFRESH_MIS)
Correct Answer: C
C
Explanation:
In IBM QRadar SIEM V7.5, using a quick filter search requires the correct syntax to find specific elements within the event logs. The correct string to search for the elements 10.100.100.*, Bluecoat, and TCP_REFRESH_MIS is:
String Structure: "10.100.100.*%AND%Bluecoat%AND%TCP_REFRESH_MIS"
Elements: This string combines the IP address pattern, device type, and specific event message using %AND% to ensure that all three elements are included in the search results.
Quotation Marks: The quotation marks are necessary to group the search terms and ensure that the search engine interprets them correctly.

Question #39
An administrator would like to optimize event and flow payload searches for log data that is stored for up to a month.
What does an administrator need to do to achieve that requirement?
- A . Perform a clean on the search model.
- B . Configure the retention period for property indexes.
- C . Configure the retention period for payload indexes.
- D . Configure the retention period for search indexes.
Correct Answer: C
C
Explanation:
To optimize event and flow payload searches for log data stored for up to a month, an administrator should configure the retention period for payload indexes.
Here’s the process:
Retention Period Configuration: Set the retention period for payload indexes to match the desired data storage duration (e.g., one month).
Improved Search Efficiency: By configuring the retention period appropriately, QRadar ensures that the indexed data is efficiently searchable, improving performance during searches.
Index Management: Regularly manage and clean up indexes to maintain optimal system performance and storage utilization.
Reference
The IBM QRadar SIEM administration guides provide instructions on configuring retention periods for
various types of indexes, including payload indexes, to optimize search performance.

Question #40
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?
- A . Set as Default
- B . Include in my Quick Searches
- C . Include in my Dashboard
- D . Share with Everyone
Correct Answer: A
A
Explanation:
Similar to the previous question, when a QRadar administrator creates a new saved search and wants it to be the first search displayed upon opening the Log Activity tab, the correct option to enable is "Set as Default." Here’s the detailed process:
Saved Search Creation: The administrator specifies the search parameters and criteria to create a new saved search.
Enabling Default Setting: By selecting the "Set as Default" checkbox, the administrator ensures that this search will automatically run and display when the Log Activity tab is accessed.
Utility: This option is particularly useful for quickly accessing the most relevant data without needing to manually select and run the saved search each time.
Setting a default search helps maintain focus on critical security events by providing immediate access to predefined search results.
