ServiceNow Updated CIS-Discovery Exam Questions and Answers by haleema

Discovery finds and maps dependencies for the following types of storage devices: Direct-attached storage (DAS), network-attached storage (NAS), or storage area network (SAN)1. NAS or SAN storage that is discovered via a Storage Management Initiative Specification (SMI-S) and Common Information Model (CIM) is also supported2. Discovery collects information about storage area networks from specialized devices, such as storage arrays and Fibre Channel (FC) switches, and creates specific references between the tables in the SAN3. Discovery does not support Multiple area network (MAN) or Redundant Array of Independent Disks (RAID) as types of storage devices.

 CI reclassification is the process of changing the class of a CI in the CMDB based on the discovery data. It can be done manually or automatically, depending on the configuration settings. CI reclassification can result in data loss if the new class has fewer or different attributes than the original class, and the existing attribute values are not preserved or mapped to the new class. This can happen when a CI is switched to a different class hierarchy, such as from a Linux Server to a Windows Server, or when a CI is downgraded to a less specific class, such as from a Database to a Software Instance. Therefore, switching and downgrading have a higher chance of leading to lost data during CI reclassification.

The image provided shows a ServiceNow expression used to concatenate two pieces of information. The $name_details[1] suggests that 'name_details' is an array or a list variable, and we're accessing the second element (considering indexing starts at 0). This indicates that 'name_details' is not a tabular variable but rather a list or an array, and there is a scalar value labeled '1' which is being used to index this array. The 'exec_info' and 'executableDir' are likely attributes or properties of the objects within the 'name_details' array and '$process' object, respectively. There is no indication that this is from a WMI query operation step, nor is there any inherent reason why this value could not be used in a pattern step. ServiceNow Discovery patterns can use such expressions to extract and concatenate data during the discovery process.

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.
