Which of the following is not true about the distribution layer?

a. Point where the individual LANs connect to the network.
b. Routing and filtering is done here.
c. The speed is slower than the core layer.
d. All the above are true.

d. All the above are true.
Explanation: The distribution layer in the network is the point where the individual LANs connect to the campus network routers or Layer 3 switches. Routing and filtering policies are more easily implemented at the distribution layer without having a negative impact on the performance of the network data traffic. Also, the speed of the network data connections at the distribution layer is typically slower than at the core.

b. Which routers can be connected on the distribution layer?
c. Which layer will the hosts be on?
