What is a key component of the Horizontal Pattern probe?

The key component of the Horizontal Pattern probe is its inclusion of a sensor specifically designed for horizontal discovery, known as the Horizontal Discovery Sensor. This sensor plays a critical role in executing the discovery process for horizontal patterns, which are used to identify and map out various elements within the network infrastructure, such as servers, services, and applications.

The Horizontal Discovery Sensor functions by collecting data as it interacts with devices in a designated range or network segment, allowing for comprehensive visibility into the infrastructure. This capability ensures that the discovered items can be accurately represented in the Configuration Management Database (CMDB), thereby facilitating better management and decision-making processes.

While other aspects mentioned in the options are relevant to the broader context of discovery, they do not define the primary focus of the Horizontal Pattern probe as effectively as the presence of the Horizontal Discovery Sensor does. This sensor's design and functionality are what enable the probe to perform specialized probing tasks needed for effective network mapping and management.
