Pass the ServiceNow Certified Implementation Specialist CIS-Discovery Questions and answers with ValidTests

A MID Server needs to have access to the install.service-now.com domain to automatically stay up-to-date with instance versions. This domain hosts the MID Server upgrade files that are downloaded and installed by the MID Server when a new version is available. The MID Server checks for updates every 24 hours by default, or when the mid.upgrade.check_interval property is set12.

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.

The Debug Identification Section in Debug Mode allows you to specify the identification attributes of a CI that you want to debug. These attributes are used to find the CI in the CMDB and run the pattern on it. The identification attributes vary depending on the CI class, but for infrastructure patterns, the common ones are IP and Host Name. These attributes are also used by the horizontal discovery to identify CIs. AWS Endpoint and PID are not valid identification attributes for infrastructure patterns.

A check is a part of Agent Client Collector that defines the osquery commands to run on a CI and the frequency of execution. A check can also specify the conditions for generating alerts or events based on the osquery results.

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 .

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.

In ServiceNow Discovery, the reconciliation process is governed by precedence rules. These rules determine which data source’s information will be retained if there are conflicts when multiple sources discover the same CI. In this case, Altiris has a higher order of precedence (300) compared to ServiceNow (100), as seen in the “Data Source Precedents” section of the image. Therefore, if Altiris discovers ‘Windows2’ for the name attribute on the same CI after ServiceNow sets it to ‘Windows1’, the name will change to ‘Windows2’ due to Altiris’s higher precedence.

The correct variable syntax to populate a custom column in a horizontal discovery pattern is $cmdb_ci_linux_server.u_custom_column.INSERT. This syntax indicates that the value of the custom column will be inserted into the cmdb_ci_linux_server table for the current CI. The other options are either invalid or incorrect syntaxes for this operation12.

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 scheduled job is a background process that runs at a specified time or interval to perform a specific task1. It is not a method for deleting specific CIs that are not discovered in 30 days. The other options are methods for deleting or updating CIs based on discovery data. A UI policy is a script that can dynamically change the behavior of a form or list2. A service mapping is a process that creates a map of the relationships between CIs that support a business service3. A data policy is a rule that enforces data consistency and accuracy by validating the data entered into a record.
