Hi Developers,

Can someone help to explain why D is the correct answer here. Tia.

Which choice represents the three best ways of extending Discovery?

B. Fingerprinting, Classifiers, Discovery Patterns

C. Orchestration, Classifiers, Probes & Sensors

D. Classifiers, Probes & Sensors, Discovery Patterns

D is the correct answer because it represents the three best ways of extending ServiceNow Discovery:

1. Classifiers: Classifiers are used to identify specific devices or systems that are found during the Discovery process. They classify devices based on a set of conditions and assign a CI (Configuration Item) type accordingly. Classifiers ensure that discovered data is accurately organized in the CMDB (Configuration Management Database).
2. Probes & Sensors: Probes are scripts that gather information about devices and systems during the Discovery process. They are responsible for querying the devices and collecting the required data. Sensors, on the other hand, parse and process the data collected by probes. They take the raw data, process it, and then create or update the CI records in the CMDB. By extending probes and sensors, you can gather additional information or improve the data processing capabilities of your Discovery process.
3. Discovery Patterns: Discovery Patterns are a more advanced and flexible method of discovering and mapping devices or systems. They use a graphical pattern designer to define the order and flow of Discovery steps. Patterns provide greater control over the Discovery process and allow you to model complex systems and relationships between CIs. By creating custom patterns, you can tailor the Discovery process to your organization's specific needs.

In contrast, Orchestration is a separate module in ServiceNow that automates tasks and processes across multiple systems. While it can be integrated with Discovery, it is not a direct way of extending the Discovery process itself. Fingerprinting is a part of the identification process in Discovery, but it is not a way to extend Discovery like the other options mentioned in answer D.
