Objective 3.2
Cybersecurity Defense AnalystDescribe SIEM best practices and basic operation concepts of Splunk Enterprise Security, including the interaction between CIM, Data Models and acceleration, Asset and Identity frameworks, and common CIM fields that may be used in investigations
Objective 3.2 sits in Defenses, Data Sources, and SIEM Best Practices, which carries 20% of the Cybersecurity Defense Analyst exam. The questions below are original, written from the official objective title above, and each explanation cites the Splunk page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
A team is onboarding firewall, proxy and endpoint feeds from four vendors and installs the CIM add-on before building searches. What is the CIM?
Correct.
Checked against help.splunk.com, August 2026Concept
Normalizing after indexing rather than before it keeps the raw record intact. The same events can then be read a second way when the first turns out to be wrong.
Why D
Splunk documents the CIM as a shared semantic model focused on extracting value from data, implemented as an add-on of data models, documentation and tools.

Splunk Docs: Overview of the Splunk Common Information Model, checked August 2026The Splunk Common Information Model (CIM) is a shared semantic model focused on extracting value from data. The CIM is implemented as an add-on that contains a collection of data models, documentation, and tools that support the consistent, normalized treatment of data for maximum efficiency at search time.
Now you: objective 3.2 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
One firewall logs a blocked connection as deny and another logs it as drop, yet both must feed one Network Traffic search. How does the CIM relate them?
Sample question 2 of 3
A compliance officer worries that normalizing logs through the CIM alters what was originally collected. What does the CIM leave intact when it defines relationships in event data?
Sample question 3 of 3
An administrator installs the Common Information Model add-on in a distributed deployment. Where does Splunk say to install it?
