Selected Answer: B

What IP Service Affinity Does (per the documentation): “The IP service affinity functionality stores a mapping between an IP address, port, and the application service class that Discovery identified on that port.” So: • It remembers what application (e.g., Apache, Oracle, Tomcat) was found running on a specific IP/port combo. • This helps ServiceNow optimize future discoveries of application services, not infrastructure.

Selected Answer: D

A system property called glide.discovery.ip_service_affinity allows Discovery to remember the last port of the IP address that was discovered. This property is set to false by default.
