IBM Exam C1000-156 Topic 6 Question 18 Discussion

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.
