What must match with the CI Type/Class in order for the CMDB to be populated?

The correct choice relates to the requirement for the Configuration Management Database (CMDB) to be effectively populated when implementing ServiceNow Discovery. Specifically, the classification of Configuration Items (CIs) is pivotal since the information captured must align exactly with the CI Type or Class in the CMDB. This alignment ensures that the data being discovered from IT assets is categorized correctly, allowing for accurate storage and management of this information in the CMDB.

Each CI type or class in ServiceNow is represented by a specific table within the database. When the data retrieved through discovery aligns with the CI classes already present, it can be accurately stored and reflected within the appropriate tables. This reflects the underlying structure of ServiceNow’s database where each class correlates to a particular table, making it crucial for populating the CMDB effectively.

Options concerning the number of CI classes associated with a pattern, the protocol for MID communication, or the phase of exploration do not directly dictate how data should match with the CI Type/Class in the CMDB. They relate to different aspects of the discovery process but do not have the same direct impact on the requirement for correctly populating the CMDB based on CI definitions.
