ServiceNow Certified Implementation Specialist - Discovery CIS-Discovery Exam Questions

Answer : A, B

Answer : D

The default thread count for a MID Server is 25. This means that the MID Server can run up to 25 worker threads simultaneously to execute the jobs assigned to it by the ServiceNow instance. The worker threads are divided into different thread pools based on the priority of the jobs. The MID Server can also adjust the thread count dynamically based on the system resources and the workload.The thread count can be configured by changing the MID Server parameters in the ServiceNow instance12.Reference=1: MID Server Max Threads - Worker Groups - Priority and Queues - ServiceNow2: Product Documentation | ServiceNow

Answer : C

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.

Answer : A, C

The Pattern Designer is a graphical tool that allows users to create and edit horizontal discovery patterns. The Pattern Designer has three main sections: the left section shows the CI type and the pattern type, the middle section shows the pattern steps and the flow diagram, and the far-right section shows the details of the selected step or operation.The far-right section can display the following tabs, depending on the type of step or operation selected12:

Operations: This tab shows the list of available operations that can be added to the pattern, such as Execute Command, Parse File, Set Parameter Value, etc. Operations are the basic building blocks of a pattern that perform specific actions on the target device or the MID Server.

CI Attributes: This tab shows the list of attributes that can be set or updated for the CI type of the pattern, such as name, serial number, manufacturer, etc. CI attributes are used to populate the CI record in the CMDB with the information collected by the pattern.

Temporary Variables: This tab shows the list of temporary variables that can be created or used by the pattern, such as $result, $output, $user_var, etc. Temporary variables are used to store and manipulate data within the pattern, such as the output of a command, the value of a parameter, or the result of a calculation.

CMDB Dashboard: This tab shows the CMDB dashboard that displays the CI record and its related lists, such as relationships, identification rules, sensors, etc. The CMDB dashboard is used to preview and verify the outcome of the pattern on the CI record in the CMDB.

Answer : A, B, D

In a Merge Table pattern operation within ServiceNow Discovery, the editable fields typically include the Target Table, Second Table, and First Table. These fields are configurable and allow users to specify the tables involved in the merge operation. The Target Table is where the merged data will be stored, while the First and Second Tables are the source tables whose data is being merged. The Primary Table is not typically an editable field in this context. Reference = ServiceNow Discovery documentation, particularly the sections discussing pattern design and operations, including Merge Table operations within Discovery Patterns.
