CIS-Discovery Exam Dumps - ServiceNow Certified Implementation Specialist Questions and Answers

During the Discovery process, the Model Category of the Configuration Item (CI) determines if an Asset record is created. A Model Category is a grouping of models that share the same asset tracking strategy and the same CI and Asset tables. The asset tracking strategy defines whether Discovery creates an Asset record for each CI of that Model Category. There are three possible asset tracking strategies: Create Assets, Don’t create Assets, and Create Consumable Assets12.

Hardware Models are templates that define the attributes and default values for a specific type of hardware configuration item (CI). Hardware Models can have a one-to-many relationship with the following entities:

Assets: An asset is a tangible or intangible resource that is tracked and managed by the organization, such as a laptop, a license, or a contract. A Hardware Model can be associated with multiple assets that share the same characteristics and specifications.

Configuration Items: A CI is any component that needs to be managed in order to deliver an IT service, such as a server, an application, or a user. A Hardware Model can be associated with multiple CIs that share the same characteristics and specifications.

Model Categories: A model category is a classification of Hardware Models based on their function, such as network, storage, or server. A Hardware Model can belong to one or more model categories that define its scope and usage.

The image shows a part of a horizontal pattern in Pattern Designer that uses the WMI Query operation to retrieve information about the processes running on a Windows server. The operation takes a WQL query as an input parameter and returns a tabular variable that contains the results of the query. The tabular variable is named ‘WMI Query’ by default, but it can be renamed by the user. The WQL query in the image selects four attributes from the Win32_Process class: Name, MaximumWorkingSetSize, PageFaults, and PeakVirtualSize. These attributes are stored as scalar variables in the tabular variable, and they can be accessed by using the dot notation, such as WMI Query.Name or WMI Query.MaximumWorkingSetSize. Therefore, the most probable results of the image are a tabular variable named ‘WMI Query’ and two scalar variables named ‘MaximumWorkingSetSize’ and ‘PeakVirtualSize’.

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.

The Duplicate CI Remediator is a feature of ServiceNow Discovery that helps to identify and merge duplicate CIs in the CMDB. It uses predefined rules and criteria to compare CIs across different data sources and determine if they are duplicates. It also provides a user interface to review and approve the suggested merges, or to manually merge CIs as needed. The Duplicate CI Remediator helps to improve the accuracy and quality of the CMDB data and reduce the maintenance efforts.

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 Functionality Definition is a configuration record that defines what protocols to detect from within a Behavior. A Behavior is a set of Functionality Definitions that Discovery uses to identify and explore a device or application. A Functionality Definition specifies the order, type, and parameters of the probes that Discovery launches to gather information about a device or application12.

The Credential Affinity table is a table that associates an IP address and a credential in Discovery1. It is used to store the credential that was successfully used to access a device during Discovery2. It can also be used to manually assign a credential to an IP address or a range of IP addresses3. The other options are not tables that associate an IP address and a credential in Discovery. The Service Affinity table is a table that associates a business service and a credential. The Service CI Association table is a table that associates a business service and a configuration item (CI). The Tags table is a table that stores tags that can be applied to records in any table.

The Shazzam Batch Size property determines how many IP addresses are scanned by a single Shazzam probe1. If this value is set to 1000 and a discovery must scan 10,000 IP addresses using a single MID Server, it creates 10 Shazzam probes with each probe scanning 1000 IP addresses. This property can be configured in the Discovery Properties module under Discovery Definition2.
