What are the two main types of Horizontal Discovery Patterns?

The correct answer focuses on the two main types of Horizontal Discovery Patterns in ServiceNow Discovery: Infrastructure and Applications.

Horizontal Discovery Patterns are designed to help identify and map the relationships between various IT resources. In this context, "Infrastructure" refers to the foundational elements that support the IT environment, such as servers, storage, and networking devices. "Applications," on the other hand, pertain to software programs that operate on the infrastructure, including databases and application servers. Together, these two categories provide a comprehensive view of the IT landscape, allowing organizations to understand how their infrastructure supports application performance and availability.

This distinction is crucial because effective discovery of both infrastructure and applications enables IT professionals to manage dependencies, optimize resources, and ensure better service delivery. In contrast, while the other options mention various components of the IT environment, they don't represent the overarching framework that Horizontal Discovery Patterns aim to achieve. For instance, "hardware and software" might capture the essence of IT components but fails to fully underscore the relationship and structural aspects that Infrastructure and Applications convey.
