NEW QUESTION # 39
Which is a valid routing rule combination?
- A. Forward and Bypass Correlation
- B. Drop and Bypass Correlation
- C. Drop and Log Only
- D. Bypass Correlation and Log Only
Answer: A
Explanation:
Forward: Data is forwarded to a specified destination. It is also stored in the database and processed by the Custom Rules Engine (CRE).
Drop: Data is dropped, meaning it is not stored in the database and is not processed by the CRE. If you select the "Drop" option, any events that match this rule are credited back 100% to the license.
Bypass Correlation: Data bypasses the CRE but is stored in the database. This option allows events to be used in analytic apps and for historical correlation runs. It's useful when you want specific events to skip real-time rules.
Log Only (Exclude Analytics): Events are stored in the database and flagged as "Log Only." They bypass the CRE and are not available for historical correlation. These events contribute to neither offenses nor real-time analytics.
Now, let's look at the valid combinations:
Forward and Drop: Data is forwarded to a specified destination, but it is not stored in the database or processed by the CRE. Dropped events are credited back to the license.
Forward and Bypass Correlation: Data is forwarded to a destination and stored in the database, but CRE rules do not run on it. Useful for scenarios where you want events to bypass real-time rules but still be available for historical correlation.
Forward and Log Only (Exclude Analytics): Events are forwarded to a destination, stored as "Log Only," and bypass the CRE. They are not available for historical correlation and are credited back to the license.
NEW QUESTION # 40
What parameter contributes to the magnitude score of an offense?
- A. Integrity
- B. Availability
- C. Confidentiality
- D. Credibility
Answer: 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.

NEW QUESTION # 44
When will events or flows stop contributing to an offense?
- A. When the offense becomes inactive
- B. After the offense is assigned to an analyst
- C. When you protect the offense
- D. When the offense becomes dormant
Answer: D
Explanation:
In IBM QRadar SIEM V7.5, events or flows stop contributing to an offense when the offense becomes dormant. Here's how it works:
Dormant Offense: An offense becomes dormant when there is no new activity contributing to it for a specified period. This indicates that the threat or incident has not had any further related events or flows.
Contribution Stoppage: Once an offense is marked as dormant, no additional events or flows are added to it, which helps in managing the offense lifecycle and resources within QRadar.
This behavior helps in distinguishing between active and inactive threats, allowing security analysts to focus on ongoing incidents.
