Which of the following are components of a structured cabling scheme?

A structured cabling scheme is a standardized architecture that consolidates and organizes the cabling used in a network. It is crucial for ensuring efficient communication and organization within a building. Each of the components mentioned plays a vital role in the overall cabling infrastructure.

The work area refers to the space where users connect devices to the network, typically including outlets and wiring for end-user equipment. This area is essential as it ensures that users can access network services effectively.

The telecommunications room, often called the server room or main distribution area, is where the network equipment (such as switches, routers, and servers) is housed. This room serves as a central point where the cabling converges and is essential for housing critical systems that manage network traffic and connectivity.

Horizontal cabling is the cabling that runs from telecommunications rooms to the work areas. This component connects all the individual work areas to the telecommunications room and ensures data transfer throughout the network.

Since each of these components is vital to a structured cabling scheme, encompassing all facets of network installation and organization, the answer that includes all of them is indeed correct.
