Correct answer & explanation
✓
To speed up searches by pre-aggregating data into smaller datasets
Summary indexing in Splunk is used to precompute and store aggregated results from a search, which allows subsequent searches to run much faster by querying the smaller summary index rather than the full raw data. Option D correctly describes this purpose. Option A is incorrect because summary indexing does not compress raw data; it creates new, summarized data. Option B is incorrect; summary indexing is not used for real-time alerts—alerts are separate. Option C is incorrect; summary indexing does not normalize data to the CIM; data model acceleration or other features do that.
