The correct answer is that ticket closure is not a way to populate the Configuration Management Database (CMDB). The CMDB relies on various methods to gather and update information about configuration items (CIs), but ticket closure does not serve as a mechanism for directly populating this critical database.

Web Services play a significant role in integrating external systems to push data into the CMDB in a structured format. Discovery is another essential method, as it employs automated processes to identify and record CIs and their relationships within the infrastructure. Manual input allows users to add or modify records directly within the CMDB, providing flexibility for situations that may not be captured automatically.

In contrast, ticket closure refers to the process of resolving and closing incident or service request tickets in service management. While ticket closure may involve updating CI information as part of the incident or request resolution, it does not inherently contribute to the direct population of the CMDB itself. Therefore, it is correctly identified as the option that does not populate the CMDB.
