What must be validated after a MID server is installed and marked 'Up'?

After a MID server is installed and marked 'Up', it is essential to validate that it can execute successfully. This is critical because the MID server acts as a communication bridge between the ServiceNow instance and the external network, facilitating the discovery of devices and applications.

Validation involves confirming that the MID server can initiate and complete its designated tasks without issues. This includes checking its connectivity with the ServiceNow instance, ensuring that it can perform discovery on the assigned network segments, and verifying that it can properly interact with the various devices within the environment. Successful execution signifies that the MID server is functioning as intended and can effectively contribute to the overall discovery process.

Understanding this importance highlights how critical validation is to maintain data integrity and operational efficiency in using ServiceNow for discovery.

The other options do suggest important aspects of server management and monitoring but do not pertain directly to the immediate requirement of confirming successful operation following installation. Security checks, performance monitoring, and restart schedules are typically part of ongoing maintenance and operational best practices rather than initial validation post-installation.
