Which of the following are key components of IBM QRadar?

The key components of IBM QRadar include data nodes, event processors, and flow processors, which play crucial roles in the operation and functionality of the SIEM system.

Data nodes are essential because they store and manage data collected from various log sources. They ensure that all relevant information is available for analysis and reporting. Event processors are responsible for the real-time processing of events generated by different data sources. They aggregate and normalize this data, allowing for more efficient analysis and threat detection. Flow processors, on the other hand, manage network flows collected from various devices, providing insight into network behavior and potential issues.

Together, these components work in unison to ensure that QRadar can effectively analyze security data, detect potential threats, and deliver actionable insights to security teams. Their integration is critical for maintaining a robust security posture within an organization. This foundational structure is what makes QRadar a powerful tool for security information and event management.

Other options mentioned include terms that do not align with the core architecture of QRadar, focusing instead on components or functions that are either not standard in QRadar's framework or misrepresent the architecture's fundamental elements.
