A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

1-3Data Engineering

An engineer asks what the CIM defines for each of its data models. What does Splunk document?

A fixed index layout per domainThe CIM is a search-time schema rather than an index layout.
Every field a vendor may emitSplunk contrasts this with the DMTF model, which is more complete.
The least common denominatorCorrect · your answerCorrect.
A retention policy per domainRetention is unrelated to the model definition.

Correct.

Concept

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.

Source

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.
