Which of the following is NOT a type of trace that can be conducted in a utility network?

In a utility network, the types of traces that can be conducted are designed to help users analyze the flow of resources and the relationships between different components within the network. An isolation trace is used to identify all assets that would be isolated when a specific component is deactivated. An upstream trace is aimed at finding all items that supply a given component, while a downstream trace identifies all items supplied by that component.

The term "reverse trace" is not a recognized type of trace in utility network analysis. Tracing typically follows a specific flow direction—upstream or downstream—based on the physical or logical relationships governed by the network's properties. Since "reverse trace" does not correspond to an established tracing methodology in utility networks, it stands out as the correct choice for what is not a type of trace that can be conducted in such contexts.
