What is the primary purpose of the Splunk Common Information Model (CIM)?

To enforce a single mandatory data format that all sources must use before sending data to Splunk

To replace the need for indexers by storing all normalized data in a separate high-performance database

To automatically encrypt all indexed data to meet compliance requirements

To provide a standardized set of field names and event tags that allow data from different sources to be searched and analyzed consistently

An analyst is troubleshooting why a specific sourcetype is not populating the `user` field in the Authentication data model, even though the raw events contain a `UserID` field. The CIM Validation tool shows the events are tagged correctly. The analyst checks props.conf and sees no alias for `UserID`. What is the most efficient fix?

Modify the raw events during ingestion to rename `UserID` to `user`.

Create a calculated field that extracts `UserID` and names it `user`.

Use event tagging to add the `user` tag to the sourcetype.

Add a field alias in props.conf and transforms.conf mapping `UserID` to `user` for the sourcetype.

When extending a CIM data model with custom tags, what is the best practice to maintain normalization?

Avoid using any tags and rely solely on field names for normalization

Use custom tags in addition to the standard CIM tags, not as replacements

Use the same custom tag for all events regardless of domain

Replace all standard CIM tags with custom tags to avoid confusion

A security engineer runs the CIM Validation tool and sees that a sourcetype has events tagged with `authentication` but the `src` field is not populated. The raw events contain a field named `Source_IP`. The validation report also shows that `user` is correctly populated. What should the engineer do to fix the `src` field issue?

Create a calculated field that extracts `Source_IP` and names it `src`.

Re-ingest the data with a sourcetype that already has the `src` field defined.

Add the `network` tag to the sourcetype so the `src` field is recognized.

Add a field alias mapping `Source_IP` to `src` in props.conf and transforms.conf.
