Which of the following is a component of backbone cabling that runs between building floors?  Group of answer choicesVertical cross connectIDFMDFWork area

Identifying the Correct Component

To find the component of backbone cabling that runs between building floors, we need to examine the options provided:

1. Vertical cross connect: This refers to a connection point that allows for the interconnection of wiring between levels of a building, particularly in vertical systems.

2. IDF (Intermediate Distribution Frame): This is a distribution frame that connects horizontal cabling to the backbone cabling; it is typically located in a wiring closet.

3. MDF (Main Distribution Frame): This connects the telecommunication or data lines from the outside to the internal network; it is generally found on the main floor or a central location.

4. Work area: This refers to the area where end-user devices are connected, typically not involved in the backbone routing.

Conclusion

Among the provided options, the Vertical Cross Connect is the correct answer as it specifically relates to the backbone cabling that runs vertically between building floors.
