ServiceNow Updated CIS-Discovery Exam Questions and Answers by safiya

To launch any pattern, you need to specify the CI classification and the CI type. The CI classification determines the table where the discovered CI is stored in the CMDB, and the CI type defines the specific attributes and relationships of the CI. For example, if you want to discover a Windows server, you need to select the CI classification as cmdb_ci_win_server and the CI type as Windows Server. These choices are mandatory for any pattern, as they enable Discovery to identify and classify the CIs correctly.

When designing steps with operations requiring variables, it is best practice to query targets for variables1. This allows you to dynamically obtain the values of the variables from the target devices, rather than hard coding them or using scalar variables that may not reflect the current state of the target. Querying targets for variables also enables you to design for a dynamic environment, where the target configuration may change over time.

A Discovery schedule of type Configuration Item collects complete information from the scanned IP ranges and sends it to the CMDB. This type of schedule runs a series of probes and sensors to identify and classify the devices and applications on the network, and to create or update the corresponding configuration items in the CMDB. A Discovery schedule of type Configuration Item can also run patterns to discover more details and relationships about the configuration items.

The Discovery pattern log is a log that records the execution of a pattern during Discovery or Service Mapping1. It shows the success or failure of the individual pattern steps, as well as the input and output variables, the CI attributes and relationships, and the errors or warnings2. The ECC Queue is a table that displays the input and output messages from and to MID Servers3. It shows the payload of CI attributes and relationships, the Shazzam probe payload, and the relationships created, but not the success or failure of the individual pattern steps4. The success or failure of the individual pattern steps is specific to the Discovery pattern log and can be used to debug or troubleshoot the pattern execution2.
