ServiceNow Updated CIS-Discovery Exam Questions and Answers by haleema

In the ServiceNow Discovery module, under the Recommended Actions pane for an Automated Error Messages list within Discovery > Home, the possible options under ACTION ON ALL include "View instructions" and "Retry Discovery". "View instructions" allows users to see guidance on how to address the errors, while "Retry Discovery" enables users to reinitiate the discovery process for the affected devices. "Make Ranges" and "Ping IP Addresses" are not standard options in this context.References= ServiceNow Discovery documentation and user guides, particularly those discussing the management of automated error messages and recommended actions in Discovery.

The Pattern Designer is a graphical tool that allows users to create and edit horizontal discovery patterns. The Pattern Designer has three main sections: the left section shows the CI type and the pattern type, the middle section shows the pattern steps and the flow diagram, and the far-right section shows the details of the selected step or operation. The far-right section can display the following tabs, depending on the type of step or operation selected12:

Operations: This tab shows the list of available operations that can be added to the pattern, such as Execute Command, Parse File, Set Parameter Value, etc. Operations are the basic building blocks of a pattern that perform specific actions on the target device or the MID Server.

CI Attributes: This tab shows the list of attributes that can be set or updated for the CI type of the pattern, such as name, serial number, manufacturer, etc. CI attributes are used to populate the CI record in the CMDB with the information collected by the pattern.

Temporary Variables: This tab shows the list of temporary variables that can be created or used by the pattern, such as $result, $output, $user_var, etc. Temporary variables are used to store and manipulate data within the pattern, such as the output of a command, the value of a parameter, or the result of a calculation.

CMDB Dashboard: This tab shows the CMDB dashboard that displays the CI record and its related lists, such as relationships, identification rules, sensors, etc. The CMDB dashboard is used to preview and verify the outcome of the pattern on the CI record in the CMDB.

Debug mode is a feature of the Pattern Designer that allows you to test and troubleshoot your patterns in real time. To activate Debug mode, you need to have the admin role or a role that includes the pattern_designer_debug permission. Debug mode is not available for users who only have the pattern_designer_read permission1.

In a discovery pattern, CI Attributes are the fields that store the information about the configuration items (CIs) that are discovered by the pattern. The Pattern Designer is a graphical interface that allows users to create and edit patterns using drag-and-drop operations. In the Pattern Designer, there are two types of CI Attributes that are available: Main pattern CI type and Related CI types. The Main pattern CI type is the CI type that the pattern is designed to discover, such as Windows Server, Linux Server, or Database. The Related CI types are the CI types that are related to the main CI type, such as IP Address, Network Adapter, or Software Installation. Users can select the CI Attributes from these types to populate the CMDB tables with the data collected by the pattern123.
