NEW QUESTION # 36
An administrator is evaluating domain criteria based on an event. The result of a regular expression that was defined in a custom property does not match a domain mapping, and the event was automatically assigned to the default domain.
What is the order of precedence if the event does not match the domain definition for custom properties?
- A. Log source, Log source group, Event collector or data gateway, DDS
- B. DLC. Log source, Log source group, Event collector or data gateway
- C. Log source. Log source group, App Hosts
- D. DLS, Log source, Event collector or data gateway. Log source group
Answer: A
Explanation:
In QRadar, when evaluating domain criteria based on an event, the precedence order for domain assignment if the event does not match the domain definition for custom properties is as follows:
Log Source: The first criterion checked is the log source. Each event is associated with a log source, and the domain is determined based on this source.
Log Source Group: If the log source does not provide a domain match, the next criterion is the log source group. Log sources can be grouped together, and domain definitions can be applied at the group level.
Event Collector or Data Gateway: If neither the log source nor the log source group provides a match, QRadar checks the event collector or data gateway for a domain definition.
DDS (Data Domain Service): As the final step, if no other criteria match, the DDS is used to assign the default domain.
This order of precedence ensures that the most specific criteria are checked first before falling back to more general criteria, ensuring accurate domain assignment for events.

Which is a valid routing rule combination?
- A. Drop and Log Only
- B. Bypass Correlation and Log Only
- C. Forward and Bypass Correlation
- D. Drop and Bypass Correlation
Answer: C
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.
