ServiceNow CIS-Discovery Certified Implementation Specialist - Discovery Exam Practice Test

Answer : B

Credential-less Discovery is a feature of ServiceNow Discovery that allows the instance to identify configuration items (CIs) without using credentials. Credential-less Discovery uses Network Mapper (Nmap), a free and open-source network scanner, to collect information about the CIs by sending packets and analyzing the responses. Nmap must be installed on the MID Server that runs Credential-less Discovery.Credential-less Discovery can be used as a fallback option when credential-based probes fail, or as a primary option for scanning certain types of devices, such as network devices, printers, or IoT devices12.

Answer : A

The Location field for a discovered CI is populated by the Location field of the Discovery Schedule that triggered the discovery of that CI. This is done by the DiscoverySensor script, which gets the location ID from the Discovery Schedule and passes it to the Shazzam probe, which then updates the cidata with the location information. The Location field for a parent CI Type, a Port Probe, or a Discovery Dashboard report does not affect the Location field for a discovered CI.

Answer : B, C

The SNMP Query pattern operation executes an SNMP query on a target device and stores the results in a variable. The Variable Type field determines the format of the results. There are two valid Variable Types for this operation: Table and Scalar. Table is used when the query returns multiple values, such as a list of interfaces or processes.Scalar is used when the query returns a single value, such as the system name or uptime12.

Answer : A

The Discovery pattern log is a log that records the execution of a pattern during Discovery or Service Mapping1.It shows the success or failure of the individual pattern steps, as well as the input and output variables, the CI attributes and relationships, and the errors or warnings2.The ECC Queue is a table that displays the input and output messages from and to MID Servers3.It shows the payload of CI attributes and relationships, the Shazzam probe payload, and the relationships created, but not the success or failure of the individual pattern steps4.The success or failure of the individual pattern steps is specific to the Discovery pattern log and can be used to debug or troubleshoot the pattern execution2.

Answer : C

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 dat

a. 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.

Answer : A, D

In the context of ServiceNow Discovery patterns, the types of temporary variables include Scalar/List and Tabular/Table. Scalar/List variables are used to store single values or lists of values, while Tabular/Table variables are used to store structured data in a table format. Command and SQL statement are not types of temporary variables; rather, they are types of operations or steps that can be used within a pattern to execute commands or SQL queries. Reference = ServiceNow Discovery documentation, especially sections related to Discovery Patterns and the use of temporary variables within patterns.
