Which of the following are methods used to initiate discovery on a service? (Choose three.)

ServiceNow Service Mapping provides several methods to initiate the discovery and mapping of application services. The primary methods involve defining entry points, which are the access points for a service (e.g., a URL or an IP address and port).
1. Suggestions from Load Balancers (A): Service Mapping can analyze discovered load balancer configurations to identify virtual IP addresses (VIPs). It then suggests creating application services for these VIPs, as they are common entry points for enterprise applications.
2. Import from CSV (B): For large-scale mapping, administrators can create a CSV file containing the entry points for multiple services. This file can be imported into ServiceNow to create and map numerous services in a single bulk operation.
3. Single Entry Point Configuration (C): This is the fundamental method where an administrator manually creates a single application service and configures its entry point. Service Mapping then uses this entry point to begin the discovery and mapping process for that specific service.

D. Map services suggested by the discovery of MID Servers in an enterprise. MID Servers are facilitators of the discovery process, not sources of service suggestions. Discovering a MID Server provides no information about a business service's entry point.
E. Map services based on Assets stored in the CMDB. This is too generic. While entry points are Configuration Items (CIs) in the CMDB, you cannot initiate mapping from a generic "Asset." The process requires a specific entry point CI type.

1. ServiceNow Product Documentation - Create mapped application services: This parent topic outlines the different ways to create application services for mapping. It explicitly lists creating a single service, creating multiple services with a CSV file, and creating services based on suggestions.

2. ServiceNow Product Documentation - Create a single mapped application service: This document details the manual process of defining a service and its entry point, which directly supports option C.

3. ServiceNow Product Documentation - Create multiple mapped application services with a CSV file: This document describes the bulk import process, which directly supports option B.

4. ServiceNow Product Documentation - Create mapped application services based on suggestions: This document explains how Service Mapping can suggest services. It specifically mentions "Suggestions from load balancers" as a primary source, which directly supports option A. It does not mention MID Servers as a source for suggestions.
