Question

What is the purpose of the core layer in the Cisco hierarchical network design model?

a. To connect end devices
b. To provide access control
c. To route traffic between different networks
d. To provide high-speed, high-capacity backbone connectivity

Answer 1

The core layer's purpose in the Cisco network design model is to provide high-speed backbone connectivity, routing data efficiently across various networks but not directly connecting end devices or controlling access.

Step-by-step explanation:

The purpose of the core layer in the Cisco hierarchical network design model is to provide high-speed, high-capacity backbone connectivity. This layer is central to the network's overall performance and efficiency, as it is responsible for the fast and reliable transportation of large amounts of data across different regions of a network. The core layer is not designed to connect end devices directly or to provide access control; its primary function is to ensure that data traffic is routed effectively between the different networks that make up the larger network infrastructure.
