ServiceNow Certified Implementation Specialist CIS-Discovery New Questions

From the Discovery Status record, a Device record in ServiceNow Discovery contains a link to the discovered Configuration Item (CI). This link provides direct access to the CI record that was discovered and processed during the discovery cycle. The Device record does not contain the contents of the CI, a link to the discovered Asset, or a link to the CMDB Health Dashboard. References = ServiceNow Discovery documentation, focusing on the details of Discovery Status records and the information contained within Device records.

A horizontal discovery pattern is a sequence of operations that collects information about a specific type of configuration item (CI), such as an operating system, a database, or a web server1. A horizontal discovery pattern does not use the connectivity section, which is only used for the application pattern type2. The connectivity section defines how to connect to a CI and run commands on it3. A horizontal discovery pattern uses the following sections1:

• Variables: Defines the variables that store the data collected by the pattern and map them to the target table fields.
• Identification: Defines the criteria to identify a CI and update or create a record in the CMDB.
• Operations: Defines the actions to perform on the target CI, such as running commands, querying databases, or parsing files.

The Set Parameter Value operation is used to assign a value to a variable in a Discovery pattern1. The syntax for this operation is as follows2:

Set Parameter Value: =

The  can be either a constant or an expression. To declare a constant, unchanging value, one must use quotes around the value. For example2:

Set Parameter Value: $name = "John"

This assigns the string “John” to the variable $name. The quotes indicate that the value is a constant and will not change. The other options, hash tag, brackets, and dollar sign, are not used to declare a constant value. They have different meanings in the syntax of the Set Parameter Value operation. A hash tag (#) is used to indicate a comment2. Brackets ([]) are used to access an element of an array or a map2. A dollar sign

The Application Pattern Type is a pattern that discovers applications and their dependencies by using probes and sensors1. It has two main components: the Run Order and the Identification Section2. The Run Order defines the sequence of probes and sensors that Discovery uses to find and classify CIs2. The Identification Section specifies the criteria that Discovery uses to identify CIs and their relationships2. The other options, CI Type and Operating System, are not specific to the Application Pattern Type. They are used for other pattern types, such as the Horizontal Pattern Type and the Service Mapping Pattern Type3 .
