The Splunk Common Information Model (CIM) add-on is a collection of pre-built data models and knowledge
objects that help you normalize your data from different sources and make it easier to analyze and report on
it3. The CIM add-on includes several data models that cover various domains such as Alerts, Email, Database,
Network Traffic, Web and more3. Therefore, options A, B and C are correct because they are names of some
of the data models included in the CIM add-on. Option D is incorrect because User permissions is not a name
of a data model in the CIM add-on.

POST workflow actions are custom actions that send a POST request to a web server when you click on a field value in your search results. POST workflow actions can be configured with various options, such as label name, base URL, URI parameters, post arguments, app context, etc. One of the options that are required to create a POST workflow action is post arguments. Post arguments are key-value pairs that are sent in the body of the POST request to provide additional information to the web server. Post arguments can include field values from your data by using dollar signs around the field names.

The tag=Priv* search will return events containing a tag named Privileged, as well as any other tag that starts
