CIS-Discovery Exam Dumps - Certified Implementation Specialist - Discovery

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.

The Extension section in a horizontal pattern is executed after the Identification sections have completed and the CI has been identified. The Extension section allows adding additional attributes or relationships to the CI, or launching other patterns for further discovery12.

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.

ServiceNow Discovery can be extended in three main ways: Classifiers, Probes & Sensors, and Discovery Patterns. Classifiers are used to identify the type of device or application that is being discovered, based on the information returned by a probe. Probes are commands or scripts that are executed on the target device or application to collect data. Sensors are scripts that process the data collected by probes and create or update configuration items (CIs) in the CMDB. Discovery Patterns are graphical representations of the discovery process that can be customized or created to discover specific types of devices or applications, using classifiers, probes, and sensors as building blocks.

For a MID Server to access servers using Windows Remote Management (WinRM), it's necessary to specify that WinRM should be used as the protocol for Windows management. This is typically done by setting the appropriate MID Server parameter, such as mid.windows.management_protocol, to WinRM. This configuration tells the MID Server to use the WinRM protocol when communicating with the target servers for executing commands and collecting data. The answer is derived from understanding how ServiceNow Discovery uses MID Servers to perform remote operations and the need to configure these MID Servers appropriately to communicate using different protocols like WinRM. It is not sufficient to just add the WinRM parameter on target servers or simply add the MID Servers as a trusted source with DNS; the MID Server itself must be configured to use WinRM. Setting a 'JEA Property' to true is not relevant to the basic configuration of a MID Server for WinRM access.

A horizontal discovery pattern is a set of steps that execute operations to identify, classify, and populate attributes for configuration items (CIs) of a specific category or class, such as infrastructure or application. A horizontal pattern can be applied to any operating system or platform that supports the required protocols and commands12.

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.

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.
