Final answer:
The distribution layer in a network serves the functions of providing network access to the user, interconnecting large-scale networks, fault isolation, and high-speed backbone connectivity.
Step-by-step explanation:
A function of the distribution layer in a network is to provide network access to the user. It acts as the intermediary between the core layer and the access layer, facilitating the flow of data between these layers and ensuring that users can connect to the network and access resources.
Additionally, the distribution layer also plays a role in interconnecting large-scale networks. It allows for the integration and communication between different networks, allowing data to be transmitted between them.
The distribution layer also serves a purpose in fault isolation. By implementing redundancy and fault-tolerant features, it can detect and isolate network faults, ensuring that the rest of the network remains operational.
Lastly, the distribution layer provides high-speed backbone connectivity. It acts as a backbone for the network, providing high-bandwidth connections that facilitate efficient communication between different parts of the network.
