Certified Implementation Specialist CIS-Discovery Book

Global variables are variables that are automatically available for all steps in horizontal discovery patterns. They store information about the target CI, such as its IP address, host name, operating system, and credentials. There are two global variables that may be used for steps in horizontal discovery patterns: system and computer_system. The system variable contains the information about the target CI’s IP address, host name, and credentials. The computer_system variable contains the information about the target CI’s operating system, such as its name, version, and architecture12.

The reconciliation process in ServiceNow refers to the method of ensuring data integrity and consistency in the Configuration Management Database (CMDB) by allowing only designated authoritative data sources to write or update information at the CI (Configuration Item) table and attribute level. This process helps maintain accurate and reliable data in the CMDB by controlling how and from where data is sourced and updated. The other options describe different processes or aspects of CMDB management and are not directly related to the reconciliation process. References = ServiceNow CMDB documentation, particularly the sections on CI data management and reconciliation processes.

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.

Without seeing the specific image, it's challenging to definitively identify the operation. However, based on the options provided, if the image shows an operation that involves interpreting or extracting data from a variable, then "Parse Variable" is the most likely answer. "Parse Variable" is used in ServiceNow Discovery patterns to analyze and extract data from variables collected during the discovery process. References = ServiceNow Discovery documentation, particularly the sections on Discovery Pattern Designer and the various operations that can be used in patterns.
