A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
An engineer asks what the CIM defines for each of its data models. What does Splunk document?
Correct.
Checked against help.splunk.com, August 2026Concept
A narrow shared vocabulary is easier to satisfy than a complete one. Defining only what every source in a domain can supply is what makes normalisation achievable at all.
Why C
Splunk documents that each data model in the CIM consists of a set of field names and tags that define the least common denominator of a domain of interest.
