IBM Updated C1000-162 Exam Questions and Answers by maxim

In IBM Security QRadar SIEM, generating a report using the QRadar Report Wizard requires a "Saved Search" and a "Layout." A Saved Search is a predefined search criterion that users save in QRadar to reuse for various reporting or analysis purposes. It acts as the data source for the report, defining what data will be included. The Layout component refers to the structure and presentation of the report, including how the data from the Saved Search is organized and displayed. It encompasses the formatting, charts, tables, and other visual elements that make up the final report. Together, these components ensure that reports are not only informative but also well-organized and readable, catering to the specific informational needs and preferences of the users or stakeholders.

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 .
