Answer: D

Answer: D

Explanation:

An extension section of a discovery pattern is a section that allows you to modify or extend the functionality of an existing pattern without customizing it. An extension section can contain shared libraries, which are reusable code snippets that can be invoked from any pattern or extension section. Shared libraries can be used to define common functions, variables, or constants that are used across multiple patterns or extension sections.Shared libraries can also be used to override the default behavior of some built-in functions, such as identification or classification12.Reference=1: ITOM: Extending Discovery/Service Mapping Patterns - GlideFast ServiceNow2: How to Create Discovery Pattern Extensions and Why to Use Them

Answer: C, D

Explanation:

Discovery and Service Mapping are both products that help to identify and map the IT infrastructure and services in an organization. However, they have different approaches and objectives. Discovery uses IP address ranges as the starting point for finding devices and applications on the network, and then runs probes and sensors to collect information and classify them. Discovery focuses on inventory-related use-cases, such as asset management, configuration management, and compliance. Service Mapping uses entry points, such as URLs or host names, as the starting point for mapping business services and their dependencies. Service Mapping runs patterns, which are sequences of operations that follow the traffic connections between devices and applications, and then creates a service map that shows the logical and semantic relationships.Service Mapping focuses on service-related use-cases, such as service availability, impact analysis, and root cause analysis12.

Explanation:

In the ServiceNow Discovery module, under the Recommended Actions pane for an Automated Error Messages list within Discovery > Home, the possible options under ACTION ON ALL include 'View instructions' and 'Retry Discovery'. 'View instructions' allows users to see guidance on how to address the errors, while 'Retry Discovery' enables users to reinitiate the discovery process for the affected devices. 'Make Ranges' and 'Ping IP Addresses' are not standard options in this context. Reference = ServiceNow Discovery documentation and user guides, particularly those discussing the management of automated error messages and recommended actions in Discovery.
