Which of the following methods is last in the port probe order?

In the context of ServiceNow Discovery, the correct sequence of the port probe order is important for establishing connections to devices and gathering data. HTTP is last in the port probe order because it is typically seen as a higher-level application layer protocol.

Discovery starts with low-level access methods, which are more direct and can provide broader access to information about the devices being scanned. For instance, SNMP and WMI allow for querying specific attributes of devices and operating systems. SSH, being a secure shell protocol, provides command-line access and is also prioritized higher than HTTP due to its robustness and security features.

HTTP is often used to access web-based interfaces or APIs for devices, but it is considered last in the order because it generally requires that other options (like SNMP and SSH) first establish a connection or gather critical information. As a result, using more foundational protocols first helps ensure a smoother and more thorough discovery process.

Thus, understanding that HTTP is the final method employed in the port probe order clarifies why it plays a unique role in the broader context of ServiceNow’s Discovery process.
