SPLK-1002 Macros, Saved Searches and CIM Practice Question
An organization uses the Splunk Common Information Model (CIM) to normalize data from various sourcetypes. After onboarding a new firewall vendor, the data is not populating the Network Traffic data model. Which of the following is the most likely cause?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The appropriate CIM tags have not been assigned to the new sourcetype.
The Splunk CIM uses tags to map sourcetypes to specific data models. Without the appropriate CIM tags (such as 'network' or 'traffic'), the data will not populate the Network Traffic data model, even if the sourcetype is included in data model acceleration or indexed into any index. Option A is incorrect because data model acceleration includes all sourcetypes unless explicitly excluded, but tagging is still required for data model population. Option C is irrelevant because custom indexes do not affect CIM mapping; tagging is the key factor. Option D is incorrect because the CIM normalizes fields via tags and field aliases—exact field name match is not required if proper tags are assigned.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The sourcetype is not included in the 'Network Traffic' data model acceleration.
Why it's wrong here
Acceleration includes sourcetypes automatically if they are tagged correctly.
- ✓
The appropriate CIM tags have not been assigned to the new sourcetype.
Why this is correct
CIM uses tags like 'network' or 'traffic' to map events to data models.
- ✗
The data is being indexed into a custom index that is not monitored by the data model.
Why it's wrong here
Data models work across all indexes; tags are the key mapping mechanism.
- ✗
The fields in the firewall data do not match the data model field names exactly.
Why it's wrong here
CIM mapping uses field aliases and can accommodate field name differences through configuration.
