ServiceNow CIS-Discovery Exam Questions

In the context of ServiceNow Discovery patterns, the types of temporary variables include Scalar/List and Tabular/Table. Scalar/List variables are used to store single values or lists of values, while Tabular/Table variables are used to store structured data in a table format. Command and SQL statement are not types of temporary variables; rather, they are types of operations or steps that can be used within a pattern to execute commands or SQL queries. Reference = ServiceNow Discovery documentation, especially sections related to Discovery Patterns and the use of temporary variables within patterns.

In ServiceNow Discovery, a horizontal discovery pattern refers to the logical set of steps that the Discovery process executes to find CI information across the network. Each step in a horizontal discovery pattern performs specific operations such as running probes, executing commands, or querying databases to gather information about the configuration items (CIs). It's about expanding the breadth of discovery across devices and applications, rather than going in-depth into a specific CI's details, which would be vertical discovery. Classifiers, credential depots, and port scanning tools are part of the discovery process but do not describe the horizontal discovery pattern itself.

For ServiceNow Discovery to detect a Windows device, the Windows Management Instrumentation (WMI) service needs to be running on the host. WMI is a Windows feature that provides a standardized way to access management information about operating system components and services. Discovery uses WMI to query Windows hosts for information about their hardware, software, and system configuration. SSH is used for Unix-like systems, WinRM is an alternative Windows management protocol, and CIM (Common Information Model) is a cross-platform standard; however, WMI is the primary service used for Windows device discovery.

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. Reference = ServiceNow Discovery documentation, particularly the sections on Discovery Pattern Designer and the various operations that can be used in patterns.

In ServiceNow Discovery, relationships between Configuration Items (CIs) in a horizontal pattern are created using the 'Create Relation/Reference' operation. This operation allows the pattern to define and establish relationships or references between discovered CIs, based on the information gathered during the discovery process. Options B and C are incorrect as relationships are not automatically created nor is it true that they cannot be created via patterns. Option D, 'Create Connections,' is not a standard operation in this context. Reference = ServiceNow Discovery documentation, specifically the sections on creating and managing horizontal discovery patterns.
